Vegetable fresh-keeping bag mainly explains what a film is. Anti-fog film is a functional film that can prevent mist and water vapor on the surface of the film. It is mainly used for the display and packaging of fresh and cold products such as sushi, flowers, fruits, vegetables, and meat, following the packaging of fresh products in ordinary film packaging bags. Because the water storage layer of the large plate has a great change in the transportation and sales process, an opaque mist is generated on the packaging bag and the goods are invisible to the user, and the goods are in the bag. The mist inside is susceptible to decay and decay after contact, shortens the shelf life and the deadline of fresh produce, and quickly and anti-fog appears. Not only improves the display of fresh products. Effectively prolong the shelf life of fresh produce, and intensive use in supermarkets.
Anti-fog film has high fog-resistance, high-heat sealing strength, extremely impatient force, high double sheet, high puncture resistance, and high transparency. Safe and healthy, harmless. At present, according to its characteristics, it is further developed in terms of functions. I want to conquer the difficulty of anti-fog of industrial film in China and it may be based on the size of the fog, the effect of controlling temperature and the time of the screen.
Second, input technical content: Technology makes anti-fog masterbatch. Proportion of adding anti-fog material in the production process; control the control conditions of anti-fog film. The addition of anti-fogging agents is not sufficient to prevent the effect of fog. It increases the film fog of the shared site, which entangles the difficulty and increases the cost. At the same time, the choice of additives and reports, the opening between the balance of Li and the fog: For the requirements of the fog of the film with only a fuse, generally it must reach I5mm. The anti-fog film needs to be larger than 20N / 15mm.
In order to achieve the effect of high and low temperature fog: No refrigerator on the surface of the film at 0-49 ℃, no water droplets appear on the surface of the film, and the environment between the above and zero degrees repeats for 24 h.
Manufacturers of well-known plastic bags that are easy to tear on plastic bags have a unique feeling of stretch film tearing, but the disadvantages of application are that they are used for the preparation of plastic bags or tapes and protecting the substrate, etc. Traverso is more likely to tear. The research has developed an easy-to-tear film for the Shanghai Plastics Research Institute, which retains the benefits of film traditional polyethylene plastics, while in the longitudinal and transverse characteristics of the film, it is easy to tear based on the polyethylene resin:
① There is a good performance of tears, the cracks only tear in the longitudinal (or transverse) direction, and the cracks are straight. Easy to use and easy to open.
② Has good mechanical properties, tensile strength (vertical). Opa, 17 Cross. Structured packing and products with opal, elongation at break (150% longitudinal, cross-420) and ldpe films have better protection. ③ The heat dissipation has good sealing performance, and it can be sealed by ordinary heat sealing device.
④ Health performance, edible potassium permanganate (MVL), heavy metal (magnesium / l), evaporation residue (magnesium / l), etc., meet national standards and can be used for food and pharmaceutical packaging. (Comparable to ldpe)
⑤ Good moisture resistance.
⑥ Has good printing performance, can be printed on beautiful models.
How to prevent the aging of food plastic packaging bags?
Food plastic packaging bags are closely related to our lives. At present, there is no product that can completely replace it, but how much do you know about it? Any idea how to prevent it from aging? The following editor of Shandong plastic packaging bag will introduce the techniques of food packaging bag to prevent aging.
1. In the natural environment, that is, under the condition of direct sunlight, the strength of food plastic packaging bags will decrease by about 25% after one week, and will decrease by about 40% after two weeks, which is basically impossible to use. In other words, the storage and storage of plastic packaging bags is very important.
2. The packaging bag is placed in an open air environment and exposed to direct sunlight after packaging. The intensity will decrease sharply, so try to avoid direct sunlight.
3. Excessive participation of recycled materials is also one of the reasons to promote the aging of plastic packaging bags.
4. The temperature of the bag during storage and transportation is too high or it will be exposed to rain, which will cause its strength to decrease, and then fail to meet the quality requirements for maintaining the contents. Therefore, high temperature and rain water should be avoided in normal times.
The above are the aspects that need to be paid attention to to prevent the aging of plastic food packaging bags. I hope it will be helpful to everyone. If you have more knowledge you want to know, please call the company and we will be happy to help you.
