Is PE or PC better material for food packaging bags?

Food packaging bags are a type of packaging for direct food, and the performance of food packaging materials directly affects the storage life and taste changes of food. Choosing the right packaging materials is the key to successful food packaging. So, is PE or PC the better material for food packaging bags?
PE is a polyethylene plastic that can be processed into HDPE. HDPE is a highly crystalline, non-polar thermoplastic resin that is durable and has strong corrosion resistance. PE is widely recognized as an ideal material for contact food packaging bags in the industry. Environmentally friendly, odorless, and tasteless, with a wax like texture that meets food packaging hygiene standards. Polyethylene film, lightweight and transparent, has moisture resistance, oxygen resistance, acid resistance, alkali resistance, good ductility, is not easily damaged, and has excellent heat sealing properties. It is known as the "flower of plastics" and is an important material for food packaging bags.
 
PC, short for polycarbonate, is an amorphous thermoplastic resin with excellent comprehensive performance. It has excellent electrical insulation, elongation, dimensional stability, and chemical corrosion resistance, as well as high strength, heat resistance, and cold resistance; It can withstand temperatures up to 125 degrees Celsius, low temperatures up to -40 degrees Celsius, and has advantages such as self extinguishing, flame retardant, environmental protection, and coloring. The shadow of PC plastic can be seen everywhere in daily life. Due to the presence of trace amounts of unreacted monomer bisphenol A residue in the resin during synthesis, it is easily dissolved and affects people's health when used as food packaging bags.
