Polyethylene is the largest amount of plastic products , the most important material , is currently the world’s best materials in contact with food bags , food bags on the market are generally made ??of polyethylene material.
PVC is currently the world’s second largest after the polyethylene plastic varieties , mainly for the production of plastic bags , PVC bags , composite bags, can also be used for books , folders , tickets and other cover packaging.
Plastic poisonous?
Polyethylene (PE) is recognized as the world’s best food contact materials, non-toxic, tasteless , odorless, food packaging hygiene standards can be used to hold food , living in the production of polyethylene plastic bags used clamshell packaging mainly plastic wrap and storage bags .

Even the food and do not use plastic bags with food directly into the microwave oven . In fact, the food alone with plastic bags, plastic wrap heated in a microwave oven is not hot , but when its contact with food , hot food will change its grilled hot.
