Plastic packaging products food material selection is critical, it not only determines the quality of plastic products, but also to determine safety and environmental protection features, then dry Xin packaging materials in food plastic products What are options? There are common sheet : PET, PP
Xin packaging dry today Xiaobian to introduce PET plastic food packaging;
PET is a milky white or pale yellow, highly crystalline polymers, the surface smooth and shiny. It has excellent mechanical properties over a wide temperature range, long-term use temperature up to 120 ℃, excellent electrical insulation, even at high temperature, its electrical properties are still good.
PET plastic boxes as packaging material and its advantages:
① have good mechanical properties, impact strength is 3-5 times that of other films, folding is good.
② oil, fat resistant, resistant to acid, alkali, resistant to most solvents.
③ low temperature at -70 ℃ to use within a temperature range of 120 ℃, short-term use can withstand 150 ℃ high temperature.
④ gas and water vapor permeability is low, both excellent gas barrier, water, oil and odor performance.
⑤ high transparency, can block ultraviolet rays, good gloss.
⑥ non-toxic, tasteless, health and safety, and can be directly used in food packaging.
Currently PET is currently widely used in plastic food packaging, cosmetics and plastic packaging, electronics blister packaging, toys, plastic packaging, medical blister packaging, plastic packaging and other gifts.
PET plastic boxes of high-grade appearance, but also a 360-degree display packaged products so that consumers see at a glance and then want to buy the product, without the need to unpack. Plastic industry is one of the most commonly used material.
