The application of vacuum aluminum foil bag is actually very wide, aluminum foil bag is formed by polyethylene or polyester, aluminum foil, bidirectional tensile polypropylene, nylon and other composite, aluminum foil bag has a good waterproof and moisture-proof effect, can be widely used in a variety of drugs, food, cosmetics, precision instruments, large mechanical equipment and other products packaging. Another feature of the aluminum foil bag is that it can be coated with anti-static liquid, so that the aluminum foil bag used has an anti-static effect, and can pack electronic products, circuit boards, etc.The vacuum foil bags have the following advantages:
1. Aluminum foil surface is very clean, sanitary, any microorganisms can not grow on its surface, and can be in direct contact with food without any concern that can harm human health.
2. As an opaque packaging material, it has good protection for products exposed to the sun line, such as oily products, solid drinks, coffee, etc., is a good packaging material, whether at high temperature or at low temperature, aluminum foil will not penetrate the phenomenon.
3. Low permeability of air and water can protect the internal products well. Aluminum foil itself is not volatile, it itself and the packaged food will not dry or shrink, tasteless and odorless packaging materials, will not make the packaged food have any odor.
4. Stable performance, can adapt to a variety of high and low temperature environment storage, has a certain corrosion resistance.
5. It can be waterproof, maintain umami taste, prevent harmful microorganisms and anti-fouling. It has the characteristics of opaque, silver white, anti-gloss, good barrier, high/low temperature resistance, oil resistance, heat sealing, blocking optical activity, fragrance protection, no odor, softness and so on.
