Food is closely related to human health, health food is full of our favorite, so the demand for food box bag packaging is also very strict. In the variety of food box bag packaging, compound box bag plastic accounts for a considerable share. Some experts point out that for the future development of food box bags in the new direction: to improve the function of existing plastic, new varieties, promote the development of strength and insulation, cutting amount (thick wall), reuse, recycling classification to protect the environment.
Due to the economic model based on low energy consumption, low pollution and low emissions, low-carbon economy is another major development of agricultural civilization, industrial civilization after human society. Low-carbon economy is the essence of efficient use of electricity, the development of clean electricity, the search for green GDP query, is to reduce power consumption technology, technology and industrial structure innovation and innovation standards and fundamental human livelihood center to carry out the change of mind. Low-carbon economy and sustainable development of China is the implementation of a consistent strategy, which is also the inevitable choice of ecological civilization construction for China to build an innovative country and take the road of new industrialization.
The bag-in-the-box packaging not only enhances the protection of food, but also reduces the amount of plastic and can be reused. On the high barrier treatment of food protection and vacuum box bag packaging, inflatable box bag packaging and other conditions, generally with the need for box bag packaging in composite materials, multi-layer composite materials must have more than one layer of high insulation material. Commonly used high insulation materials, aluminum foil, nylon, polyester and so on. With the advance of foods requiring protection and the very good blocking of ethylene-vinyl alcohol copolymers, polyvinyl alcohol also began to be used. At present, developed countries and a small number of PEN, used in food box bag packaging brings many advantages. The chemical structure of THE PET PEN is similar to that of PET PEN, but the rigidity is much earlier, oxygen permeability, water resistance is several times ahead of PET, and good ultraviolet absorption, low, contains the food no odor gas adsorption, can be repeated.
