The manufacturer specializes in printing customized shampoo, shower gel and other trial automatic packaging roll films

In daily production operations, we sometimes don't know much about its material. Here are three common automatic packaging composite films, hoping to be helpful in the future procurement process.

1、 Pet/pe composite roll film:

The material of pet/pe composite is polyethylene terephthalate and high-pressure polyethylene, which is conventionally abbreviated as pet/pe composite film. It has the characteristics of high transparency and good oxygen resistance, so it is especially suitable for inflatable packaging of foods such as bread and cake. Moreover, because the composite film has good heat and cold resistance, it can also be used as a packaging bag for quick-frozen food and cooked food.

2、 Opp/cpp composite roll film:

Opp/cpp composite film is made of biaxially stretched polypropylene and non stretched polypropylene, which is customarily called opp/cpp composite film. Among all composite films, this kind of composite film is relatively transparent. Compared with single film plastic bag, under the same thickness, the cost is higher than that of single film plastic bag, but the hand feel is better than that of single film plastic bag; Because of its good moisture resistance, this film is mainly used in food, mainly for packaging some dry food and fast food, such as biscuits, instant noodles, etc. The disadvantage is that the high temperature resistance and cold resistance are poor, so it is not suitable to package refrigerated and high temperature sterilized food.

3、 Opp/pe composite roll film:

Opp/pe composite bag is composed of bi-directional polypropylene and high-pressure polyethylene composite film bag, which is generally abbreviated as opp/pe composite film. This composite film has very good gas and moisture resistance, so it is especially suitable for the packaging of products such as green tea, and its oil resistance effect is also good, so cooked food and some oil products are also packaged with this composite bag.

4、 Pa/pe composite roll film:

Pa/pe composite bag is composed of biaxial tensile nylon film and high-pressure polyethylene composite film bag, which is generally abbreviated as pa/pe composite film. This composite film has very good gas and moisture resistance, so it is especially suitable for vacuum packaging such as food, and its oil resistance effect is also good, so cooked food and some oil products also use this composite structure.

5、 Pet/pet/pe composite roll film:

Pet/pet/pe composite bag is composed of biaxially stretched polypropylene, aluminized and high-pressure polyethylene composite film bag, which is generally abbreviated as pet/pet/pe composite film. This composite film has good gas and moisture resistance, so it is especially suitable for products with low shading requirements such as ordinary biscuits and trial packaging.

6、 Pet/al/pe composite roll film:

Pet/al/pe composite bag is composed of bi-directional polypropylene, pure aluminum and high-pressure polyethylene composite film bag, which is generally abbreviated as pet/al/pe composite film. This composite film has very good gas and moisture resistance. The shading of pure aluminum is 100%, so it is especially suitable for products with high shading requirements.
