The prevalence of cooked food in supermarkets gives shrink film manufacturers a bright future

The food processing industry of shrink film manufacturers is developing rapidly, and the packaging required is also increasing. It is understood that there are many types of green packaging materials on the market, which can be roughly divided into reusable and recycled packaging materials, edible packaging materials, degradable materials and paper materials. The degradable material packaging can be degraded and restored after use, and does not pollute the environment; the paper packaging made of natural plant fiber has a high recycling value and the technology is also mature. Edible packaging materials use natural edible substances (such as polysaccharides, proteins, etc.) as raw materials to form edible packaging films through the interaction of different molecules. According to different materials and processes, it can be divided into polysaccharide edible packaging film, protein edible packaging film, composite edible packaging film, etc. This kind of shrink film manufacturers can not only use automatic, semi-automatic mechanical operation and manual operation for packaging, but also use more reasonable packaging machinery according to different product packaging methods. At present, this product has been widely used in many industries, such as daily necessities, food hygiene, and so on. POF heat shrinkable film has high transparency and good gloss, which can clearly display the appearance of the product, improve the sensory awareness, and reflect the product level. POF heat shrinkable film has a large shrinkage rate, up to 75%, and has good flexibility. It can be packaged for any shape of goods. It has high strength and is suitable for manual, semi-automatic and high-speed automatic packaging. Printing industry: PVC, PC board, aluminum board, film and other printing nameplate surface protection, etc. Using environmentally friendly materials, no toxic and harmful gases will be produced during heat sealing, and it can be used to package food and other sanitary products; good welding performance, wide welding range, good low-temperature weldability; heat shrinkage rate reaches 70%, Special-shaped products have just the right plasticity, and the packaging is natural. While ordinary packaging provides convenience for people's lives, it also generates packaging waste. This not only increases the burden on the environment, but also increases the possibility of waste of resources. With the rapid development of food technology and packaging industry, many new packaging materials and packaging forms continue to appear. Among them, experts believe that edible environmentally friendly packaging materials will lead the sustainable development of the food packaging industry. The furnace size of the shrink film manufacturer is inappropriate. There are two situations in which furnace dimensions are inappropriate. One is that the furnace is too large, and the other is naturally that the furnace is too small. The situation that the furnace is too large is that the product receives less temperature and most of the heat is lost. Therefore, it is necessary to increase the heat shrink packaging machine to a high temperature to shrink better. If the furnace is too small, the film will stick to the inner wall of the furnace, which will be burned. The recycled packaging materials are mainly plastic packaging, which can be made into recycled packaging containers after being treated by physical methods, and recycled packaging products can be made after treatment by chemical methods. Reused packaging materials are mainly used for packaging glass bottles such as beer and beverages. , Can be used repeatedly. However, these two methods have a flaw in their beauty. They only reduce environmental pollution, and in the end, they have to face the problem of environmental pollution. As the concept of low-carbon environmental protection has become the main theme of society, it is being practiced in many fields, as is the field of packaging materials.
