PRODUCTION AND CHARACTERISTICS OF LUNCH BOX MACHINE
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.

DO YOU KNOW THE REPAIR AND MAINTENANCE OF DIE CUTTING 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.
WHAT ARE THE ADVANTAGES OF HEAT SHRINK PACKAGING
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.
