What is packaging material for instant noodles
? There are many packaging material for instant noodles. And different forms of instant noodles use different packaging materials, now let's take bags instant noodles as an example. Packaging materials of bag instant noodles mainly consist of BOPP film and polyethylene.
BOPP Film: The production of BOPP films is to first make a thick film through the melt of high polymer polypropylene through a narrow and long machine head. And then in the special drawing machine, at a certain temperature and set speed, the simultaneous or stepwise stretching in two vertical (vertical and horizontal) directions, a thin film made by suitable cooling or heat treatment or by special processing (such as corona, coating, etc.) BOPP films are colorless, odorless, tasteless, non-toxic, and have high tensile strength, impact strength, rigidity, strong toughness and good transparency.
Polyethylene is a kind of thermoplastic resin produced by polymerization of ethylene. In industry, too, the copolymers of ethylene with a small number of pene-olefin are included. Polyethylene odourless, non-toxic, feel like wax, has good low temperature resistance (the lowest temperature can reach 100 ~ 70 ° C), good chemical stability can prevent most acid and base erosion. Insoluble in ordinary solvents at room temperature, small water absorption, excellent electrical insulation.
The composite of these two packaging materials can be moisture-proof, water-proof and air-proof, extending the storage time of instant noodles.
