Straws are a common type of daily necessities in our daily life, which are widely used in the field of packaging beverages and making beverages. From the material point, commonly used straw materials are stainless steel, silicone rubber, plastic, etc. However, under the constraints of many factors such as portability, safety and cost, plastic straws are still the most widely used straws. This article mainly introduces the current use status and standards of plastic straws, and provides a certain reference for the future development of the straw industry.
The Chinese National Standard
As a food-contact thing, the straw is in direct contact with the human mucosa during use. What's more, the material of the straw will inevitably migrate into the beverage and the human body. Therefore, the state has formulated relevant standards to regulate related products to ensure safety. The commonly used polymer materials for plastic straws are polypropylene (PP) and polylactic acid (PLA).
Polypropylene straw national standard
Polypropylene is a semi-crystalline thermoplastic with good toughness and mechanical strength, and it is inert and non-toxic to acids, alkalis, organic solvents, etc. This material is suitable for a wide range of temperatures. It is also used in food and beverage packaging materials and has been widely used in straws. Polypropylene straws are natural non-degradable materials, which cannot be naturally decomposed in nature. In recent years, the country has paid more and more attention to environmental protection, and straws which is made of polylactic acid came into being and came into people's vision.
Polylactic acid straw industry standard
Polylactic acid is a thermoplastic polyester material, which has good mechanical properties and processability. Moreover, polylactic acid products can be naturally degraded quickly after being discarded in a variety of ways.
At present, polylactic acid products have been applied to straws which is produced by shrink film wrapper machine, shrink wrap machine and hand held shrink wrap machine. As the country has also issued relevant standards for polylactic acid materials. This standard defines the scope of polylactic acid cold drinking straws and defines related terms. It classifies the polylactic acid cold drinking straws and gives the corresponding physical and chemical specifications, degradation and other requirements and measurement calculation standards. The standard stipulates the inspection rules for polylactic acid cold drinking straws and the requirements for sign packaging.
The Status of Plastic Straws
Plastic straws are currently widely used in packaging beverages, catering industry and household use. According to National Park Service reports, Americans use an average of 1.6 disposable straws per person per day. A person from 5 to 65 years old will use about 38,000 straws. The US uses 500 million plastic straws every day.
Plastic straws are a common part of plastic recycling. However, due to the slim shape of the plastic straw, it easily slips out of the gap during the recycling process. Many plastic straws end up in the ocean. And their shape will cause them to be eaten by some marine animals, causing damage to some marine animals, such as turtles and seabirds. When plastic straws are not recycled, they tend to accumulate in landfills. Plastic straws are often made of very thin plastic, which means that they are easily broken into small pieces of miniature plastic. This makes the recycling of plastic straws difficult. As people pay more and more attention to plastic straws, many large companies have also announced their initiatives to replace the plastic straws with paper straws produced by paper straw machine.
Although plastic straws bring convenience to human life, it does great harm to the environment. It is an inevitable trend for paper straws to replace plastic straws in the future.

Disposable paper cups are favored by many people because of their convenient use and low prices. However, while bringing convenience to the public, disposable paper cups may also have hidden health risks, especially some unqualified paper cups. However, people generally lack the common sense of choosing disposable paper cups in their daily consumption. The following are some purchasing tips for your reference.
The main problems of paper cups on the market
As a sanitary, convenient and inexpensive daily necessities, paper cups are very popular among consumers. At present, there are various disposable papers cups and many brands of the papers cups on the market, which it is difficult for consumers to purchase and use. Now the main problems of disposable paper cups on the market are as follows.
There is a discoloration phenomenon.
After the paper cup is soaked in ethanol with a temperature of 25 ° C and a purity of 65%, no discoloration is allowed. However, many paper cups have discoloration under this condition. The main reason for the problem is that the paper cup machine manufacturer used inks that did not meet the safety and practical requirements of paper cups in the printing process, and the printing process was unreasonable.
The product tag does not meet the regulations.
The product tag is a sign that the manufacturer which produce paper cups by paper cup machine, semi automatic die cutting machine, die cutting machine and automatic die cutting machine communicates the product information to the consumer, so that the consumer understands the product performance and grasps how the product is used safely and correctly. The six items stipulated by the national light industry for product tags include product name, trademark, product standard number, product production date and shelf life, product type, specification, grade and quantity, product qualification mark, product manufacturing company name and address. These information must be accurately and clearly stated. However, some companies have not attached great importance to this provision, resulting in missing or wrong tags. There are also some companies that mark product information on the bottom of paper cups with small letters, which is difficult for consumers to see.
The tips for buying paper cups correctly
Although the hygiene status of paper cups has improved, some inferior paper cups are still on the market. Consumers should have a certain sense of precautions and pay attention when purchasing and using.
Firstly, consumers should choose regular supermarkets and shopping malls to buy paper cups. Never buy paper cups at roadside stalls. Not only do the physical indicators of the paper cups on the roadside stalls not meet the standards, but also the hygiene indicators are difficult to guarantee.
Secondly, pay attention to the product tags. When purchasing paper cups, you should check whether the product label indicates the content that must be marked by national requirements such as shelf life and production date. Consumers should not buy paper cups that have no product tag. Special attention should be paid to see whether the product packaging is marked with the QS mark of quality and safety. Paper cups with the QS mark are paper cups that have passed the mandatory quality and safety inspection and are allowed to enter the market. Paper cups without the QS mark are banned by the state.
Thirdly, consumers should not buy paper cups that clearly appear blue under fluorescent lights. According to national standards, the fluorescent area of the paper cup cannot exceed 5 square centimeters. Fluorescent brighteners can make paper cups white. But this substance is harmful, which can induce cell mutation, weaken the body's immunity, or even cause cancer.

On a hot summer day, it is inevitable to go to the drinks shop to buy a cold drink to quench your thirst. But attentive customers will find that different businesses have different choices for beverage packaging, but most of them are paper cups or plastic cups. What kind of cup do you prefer?
Will you choose a plastic cup or a paper cup
People who choose plastic cups say that plastic cups are more transparent, which helps to see the color, turbidity of the drinks, and the amount of supplements added. The voice of opposition gave the following reasons: first, that plastic cups look cheaper and have a bad touch; second, that paper cups are safer, and plastic cups cannot guarantee that they will not produce hazardous substances under high temperature.
As for the appearance of the beverage packaging, the choice is different because each person has different preferences. But for the safety and health issues, whether it is the beverage itself or its packaging, they are the issues that consumers are most concerned about. Which of the disposable plastic cups and paper cups used in the beverage market is safer?
Paper cup production process
Usually disposable paper cups are composed of the following parts: paper, printing ink, industrial paraffin, coated paper. Many manufacturers do not use food grade wood pulp paper for maximum benefit. If the quality of the paper is not good (recycled waste paper), the use of bleaching powder and optical brighteners cannot be distinguished by ordinary consumers. In addition, after the printed paper cups are stacked, the ink is likely to contaminate the inner wall of the paper cup.
In order to make the paper cup waterproof, it usually needs to be soaked in paraffin. The wax contains a harmful substance called "polycyclic aromatic hydrocarbons". Polyethylene plastic film within the scientific name of coated paper. Many paper cups now use coated paper instead of paraffin. But the outer wall of the "protected" cup without paraffin may become moldy when it gets wet, causing contamination.
Production process of plastic cups
Compared with the production process of paper cups, plastic cups are much simpler. The commonly used plastic cup materials are PET, PP, PS and other materials. PET cups are generally used to make coffee cups, and their transparency is relatively high, suitable for cold drinks. The plastic cups used by chain stores like Starbucks are PET materials.
PP is resistant to high temperature, can be heated by microwave, can hold boiling water, and can be used for a long time at normal temperature. PS is not resistant to high temperatures, so it is commonly used in the field of cold beverage packaging. In the production process, plastic cups are healthier than paper cups. Because the production process of plastic cups is simple, it is packaged immediately after forming and cooling at high temperature.
Plastic cups and disposable paper cups have their own advantages and disadvantages. Different industries have different needs for the two, but there is one thing to be sure, we need to use a qualified paper cup machine to ensure the quality of the product.
We can provide you with all kinds of high-quality die-cutting machines, paper cup machines, paper plate making machines, and paper straw machines, welcome to buy on our official website.
Excellent performance of the heat shrinkable film
The heat-shrinkable film is a thermoplastic film that is stretched and oriented during the production process and shrinks by heat during use. The principle of the heat-shrinkable film is making use of the energy of the film stretched in the longitudinal or transverse direction in the high-elastic state stored in the film and the memory effect of thermoplastics on the shape before bidirectional or unidirectional stretching. It uses the function of restoring the shape before stretching to achieve the purpose of packaging. Heat shrink packaging, using shrink wrap machines, is a packaging method widely used in commodity packaging, which can be used to package various types of products. It has the characteristics of transparency, container, sealing, moisture-proof, simple process and equipment, low packaging cost and various packaging methods, which are favored by merchants and consumers. As manufacturers increasingly pursue differentiated product competition, the market for heat shrinkable film labels for packaging food, beverages and other consumer foods has developed rapidly.
The shrink film is a good film packaging material, it has the following advantages. 1. Beautiful appearance and close to the product, so it is also called skin-packing, which is suitable for all different types of product packaging. 2. Good protection. You can pack a variety of products in a heat shrinkable packaging bag. Preventing the loss of individual small commodities is also convenient for customers to carry. 3. It is especially suitable for packaging of precision instruments and high-precision electronic components. 4. Choose different resins and formulas. It can produce different mechanical strengths and heat-shrinkable films. It can be used for inner packaging with lower strength and lower weight, and can also be used for mechanical products for containers with higher strength, transport packaging (outer packaging) for building materials, etc. 5. Good anti-theft performance, a variety of food can be packed with a large shrink film to avoid loss.6. Good stability, the product will not fall in the packaging film. 7. Good transparency, allowing customers to directly see the packaged goods for customers to choose products. 8. Good economy, heat shrinkable film packaging is often cheap and with good quality.
Production and application of heat shrinkable packaging
Heat shrink packaging is a very promising form of packaging. At present, there have been cases of using heat shrink packaging to completely replace carton or half-pallet carton. However, due to the immaturity of the current domestic logistics environment, there are some obstacles to the domestic development of heat shrink technology. It is expected that heat shrink packaging will develop rapidly in 3 to 5 years.
The food industry is the largest market for heat shrink packaging. Heat shrinkable film is widely used in the packaging of various fast foods, lactic acid foods, beverages, snacks, beer cans, various alcohols, agricultural and sideline products, dry foods, local specialties, etc. Applications in non-food fields are also increasing, such as labels and caps, seals, fibers and clothing, aerosol products, sports goods, electrical appliances, cosmetics, pharmaceuticals, grease, detergents, stationery, toys, office supplies, kitchen supplies, daily necessities, sundry goods, construction materials, etc.
Shrink film wrapper machineshave different classifications according to different categories. According to the difference of the film, it can be divided into “ pe” film shrink wrap machines and “pof” shrink wrap machines. According to the size of the machine, it can also be divided into fixed shrink film packaging machine and hand-held shrink wrap machine.
The die-cutting machine is a machine that cuts the cardboard into a certain shape through a knife mold, and it is an important equipment for packaging processing. In recent years, with the development of science and technology, die cutting machines have gradually developed towards automation, intelligence, and multi-function. Then, do you know what common failures are in the maintenance of die cutting machines? How should we maintain the die cutting machine?
Die-cutting machine repair common faults
1. Die cutting indentation is inaccurate: the position of die cutting and printing is not aligned, the cardboard is inconsistent with the rules, the position does not match the printed product, the paper position is inconsistent during the operation or the paper is deformed, etc. The reason for the inaccurate location.
Solution: Recalibrate the template, align the printing and die-cutting grid positions, and adjust the positioning rules of the die-cutting machine uniformly to ensure the consistency of the paper feeding position.
2. The die cutting edge is not only bad: the steel knife of the die cutting machine is of poor quality, the knife edge is not sharp, and the adaptability to the die cutting is poor, the steel knife is seriously worn and not replaced in time, the machine pressure is not enough, and the pad paper is not properly handled during operation The reason for the die-cutting edge.
Solution: Replace with a new blade, check the die-cutting pressure, and replace the backing paper.
3. The indentation is not clear and there is a dark line: the dark line indicates the indentation that should not appear, and the fried line is a cardboard break. The reasons for these two situations are the inaccurate thickness of the copper wire pad paper, the pad paper is too high or too low; the pressure is too large or too small, the adjustment is not correct; the paper quality is not good, etc.
Solution: readjust the thickness of the copper wire stack of the die-cutting machine, adjust the pressure of the die-cutting machine, and select the best quality paper according to the process.
4. Cardboard sticking knife plate after die cutting: The reasons are that the knife edge is not sharp, the knife edge is not resilient enough, and the paper is too thick, which causes excessive pressure during die cutting.
Solution: Ensure the blade of the die-cutting machine is sharp, check the rebound level, and check the die-cutting pressure.
Maintenance measures of die cutting machine
1. Operators should pay attention to dust and clean. In actual production, a large amount of waste paper edges will be generated when die cutting the carton, and if it is not noticed, it will enter the chain transmission part, the moving platform of the die cutting part and some rotating motion parts, and may block the photoelectric detection head, etc. Cause malfunction. Therefore, the cleaning of the body of the die-cutting machine must be placed first, and then the machine can be operated without failure.
2. Oil change of die cutting machine. The main action of the die-cutting machine is that the main motor drives the slide bar and the pulley, and then drives the four pairs of toggle bars to move. It can reach 6000 sheets / hour in high-speed work. Without good lubrication and cooling is very troublesome.
How should we use the die cutting machine correctly? The next article tells you the answer.
The lunch box machine is a machine that quickly manufactures lunch boxes. Compared with the previous machines, the main feature of the lunch box machine is that it eliminates the intermediate link "pulling" of the production of blister products. It is directly formed with plastic particles and scraps. It can also be used directly, which means that it saves the power consumption of reheating after pulling the tab, which is in line with the modern concept of environmental protection and energy saving.
Production of lunch box machine
How does the lunch box machine ensure the safety of the lunch box during production? In fact, the paper trays that we often use have a reflective film on the inside and outside. This layer of material is a polyethylene water barrier film. Every paper tray machine must ensure the existence of this film during the production process. Under the effect of air, the film is simply oxidized to produce a harmful compound. Therefore, in the industry of paper tray machines, this technology of adding film is usually called the soul technology in the production process of paper tray machines.
In addition, we all know that the fast food boxes currently used are basically manufactured using plastic fast food box machines. As a catering industry that mainly uses such plastic boxes, it can be said that it has also developed rapidly with the development of fast food boxes. Takeout packaging from the previous plastic bag packaging to the present fast food box packaging can be said to have been comprehensively developed in terms of hygiene and cleanliness. Here is a brief introduction to the standard of disposable plastic boxes in recent years.
An exquisite lunch box is very important for takeout. When we see that a take-out package is more refined, our first impression will be given a certain bonus, which is where the value of the package is for the industry. The current production of lunch box machines is also developing in a diversified direction.
Disposable lunch boxes are divided according to different materials: plastic lunch boxes, paper lunch boxes, starch lunch boxes, plant straw lunch boxes, etc., and their respective standards are different. Therefore, a manufacturer of disposable plastic lunch boxes must not only obtain a QS production license, but the quality of the products must also meet the requirements of the standard to be called a qualified disposable plastic lunch box. These standards are currently designed and manufactured through the mold of the lunch box machine.
Characteristics of meal box machine
The characteristic of the meal box machine is that the thickness of the product can be adjusted as needed. It is suitable for the production of PP blister packaging for internal and external packaging of foods such as tofu boxes, jelly cups, fast food boxes, bowls and trays. It is precisely because of the excellent performance of the lunch box machine that it is so popular in the market.
At present, most disposable plastic products are processed and manufactured using plastic molding equipment, including meal box machines and plastic cup molding equipment. Compared with general plastic processing equipment, the current sheet machinery is considered to be a better type of equipment. The reason for this is because the products produced by this machinery are currently used in cities. Including plastic lids, plastic boxes, plastic cups, etc., these are more used products. Among them, the disposable plastic fast food box produced by the lunch box machine is regarded as the most used takeout packaging form in the fast food industry. As the main packaging product, the small food box is now compared with the previous plastic bag packaging It is relatively clean and tidy, giving people a certain sense of refinement.
If you want to order a paper box machine, it is recommended that you consult the company's customer service before buying, they will provide you with quality service and useful information.

Heat shrinkable film packaging materials
At first, The PVC shrink film was the main one. With the continuous development of market demand, PVC shrink film gradually decreased, and various PE, PP, PET, PVDC, POF, PO, etc. became the mainstream of the market.
1.PVC：The PVC heat shrinkable film is produced by polymerizing vinyl chloride monomer into polyvinyl chloride resin and then chemically modifying the polyvinyl chloride resin to produce the PVC heat shrinkable film by blow molding or calendering method. The PVC shrink film has good transparency and high shrinkage. Moreover, the cost is low, the tensile strength is large, the temperature shrinkage range is large, and the requirement on the heat source is not high. However, The PVC shrink film has poor environmental protection and is difficult to recycle. Toxic gases are produced during combustion, which is not conducive to environmental protection. It has been banned in Europe and Japan. China's environmental protection requirements are not very high, and the market sales situation is relatively good. PVC is still the most important material in the field of heat shrinkable labels.
2.PVDC：PVDC is a non-toxic, odorless, safe and reliable high barrier material. In addition to the general properties of plasticity, it also has oil resistance, corrosion resistance, taste retention, and a little moisture and mildew resistance. It can directly contact food. It also has excellent printability. PVDC is mainly used for packaging cold meat. The packaging of cold and fresh meat is achieved by using a vacuum packaging machine. Taking advantage of its high shrinkage and high barrier properties, the packaged cold meat not only has a good appearance, but also keeps fresh for a long time.
3.PET：The PET film is an internationally recognized environmentally friendly heat shrinkable film material. Polyester heat shrinkable film is a new type of heat shrinkable packaging material. The main features of the PET heat shrinkable film are: good shrinkage at low temperature, high shrinkage rate, fast shrinkage, five poisons during combustion and low fever. The PET heat shrinkable film also has high transparency, gloss and excellent heat sealability, suitable for high-speed packaging equipment, with good packaging effect, low cost, non-toxic and harmless.
