Blown film still has a lot of room for improvement
In recent years, with the rapid development of supermarkets and convenience stores and the formation of cold chains, frozen foods have become more and more popular with people because of their convenient and quick features. At the same time, the rapid development of frozen foods and the implementation of the "Food Safety Law" also put forward higher requirements for the performance and safety of frozen food packaging materials.
From the processing point of view, many kinds of frozen foods have the presence of fat oxidation and aerobic microorganisms. Therefore, it is necessary to prevent the contact of products with oxygen; in the storage, in order to prevent the moisture of frozen foods from escaping from the packaging, free fat to the film. Permeation on the outside affects the flavor and intrinsic quality of the product. It also requires the barrier properties and oil resistance of the packaging materials, as well as the high degree of blockage of gases and liquids. â€
At present, the commonly used blown film in the industry basically satisfies these conditions, but at the same time there are several problems such as “easy deviation when packaging, low transparency, and insufficient material uniformityâ€.
New packaging film allows automatic packaging machine to improve efficiency by 20%
The process used for the new film is the same as the protective film process used in computer and mobile phone screen protection. The transparency and flatness are extremely high. The water droplets are not prone to occur during storage and transportation. The new film can also be used for three-layer co-extrusion. The intermediate layer can be plated with aluminum. The hardness and brittleness are all good.
The production error of the new membrane is only 1%-2%, which can avoid a lot of material waste. In addition to reducing waste at the source, due to the low temperature and high flatness of the hot air, the new film-made bags are not easy to deviate in the packaging process, allowing the automatic packaging machine to increase efficiency by 20%, greatly improving the packaging efficiency, and not wasting bags. .
In addition, due to geographical differences, the southern air is moist and the film made of the same materials and processes is printed. The colors in the north and the south are different. Zhang Jie said that the special process of the new film also solves this problem and the printing color is fuller.
New frozen food packaging film can increase efficiency by 20% for automatic packaging machine
The characteristics of frozen and refrigerated foods must be stored in a low-temperature environment, so that the packaging materials for frozen foods have higher requirements than normal temperature products. Currently, there are still many problems in the application of blown film in the industry for frozen and refrigerated foods, such as brittle fracture. Deformation, easy to break bags, material waste and more.
