First, PET/PE compoundPackaging Coil Film：

OPET/LDPE Composite bag material is polyethylene terephthalate and high-pressure polyethylene, accustomed to abbreviated as PET/PE composite bag, which has the characteristics of high transparency and good oxygen resistance, so it is particularly suitable for inflatable packaging such as bread and cake food. And because of the heat and cold resistance of this composite film is also very good, can also be used as a frozen food and cooking foods packaging bags.

Second, BOPP/CPP composite coil film:

BOPP/CPP Composite film material is bidirectional tensile polypropylene and non-tensile polypropylene, accustomed to known as OPP/CPP composite membrane bag, in all composite membranes, this composite film is relatively high transparency. Compared with single-film plastic bags, the cost is higher than that of single-film plastic bags, but the feel is better than single-film bags, but also because of the film's good moisture resistance, used in food, mainly used to package some dry food and fast food, such as biscuits, instant noodles and so on. Disadvantages are high temperature and cold resistance, not suitable for packaging refrigeration and high-temperature sterilized food.

Third, OPP/PE composite coil film:

BOPP/LDPE CompoundPackaging Coil FilmBag is composed of bidirectional tensile polypropylene and high-pressure polyethylene composite film bag, generally abbreviated as OPP/PE composite bag, this composite bag gas resistance and moisture resistance is very good, so especially suitable for products such as green tea packaging, its oil resistance effect is also good, so cooked food and some oil products are also used in this composite bag packaging.
