1、 PET/PE laminated roll film:
The material of PET/LLDPE food packaging bag is polyethylene terephthalate and high-pressure polyethylene, which is commonly abbreviated as PET/LLDPE composite bag. It has the characteristics of high transparency and good oxygen resistance, so it is particularly suitable for inflatable packaging of bread and cake. And because the heat resistance and cold resistance of the composite laminated films are also very good, it can also be used as a packaging bag for frozen food and cooked food.
2、 BOPP/CPP laminated roll film:
BOPP/CPP composite membrane is made of biaxially stretched polypropylene and untensioned polypropylene, which is commonly called OPP/CPP laminated packaging bag. Among all composite membranes, this composite membrane has high transparency. Compared with single film plastic bags, under the same thickness, the cost is higher than single film plastic bags, but the feel is better than single film bags; Because of its good moisture resistance, the film is used in food, mainly for packaging some dry food and fast food, such as biscuit instant noodles. The disadvantage is that the high temperature and cold resistance are poor, and it is not suitable to package refrigerated and high-temperature sterilized food.
3、 OPP/PE laminated roll film:
BOPP/LDPE laminated packaging bag is composed of biaxially oriented polypropylene and high-pressure polyethylene composite film bag, generally abbreviated as OPP/PE composite bag. This composite bag has very good air and moisture resistance, so it is particularly suitable for packaging products such as green tea. Its oil resistance effect is also good, so cooked food and some oil products are also packaged with this composite bag.
