BOPA film ---

 

Nylon film is a kind of paper that is very easy to absorb moisture. It will have adverse effects on the use after moisture absorption. For example, the dimensional change causes the overprinting to be inaccurate during printing, and the water film on the surface causes insufficient composite strength, foaming, etc. The nylon film should be protected from moisture in a high humidity environment. Specifically, pay attention to the following aspects:
(1) Do not open the package too early before use.
(2) Run out as much as possible, and leave the remaining film with a good barrier material.
(3) The first color group is not printed on the plate during printing, and pre-drying is performed.
(4) Put in a curing chamber for 2-3 hours before use.
(5) Ensure a reasonable temperature (25 °C ± 2 °C) and humidity (≤ 85% RH) in the production workshop. Biaxially stretched nylon film (BOPA film) is a new type of high-grade packaging material. Compared with traditional polyvinyl chloride film and polyester film, it has excellent resistance to cracking, impact, puncture and odor barrier. It is widely used as packaging materials in the fields of food processing, medical and health, chemical products, etc. It is especially suitable for frozen packaging, vacuum packaging and retort packaging. The preservation and fragrance of foods are far greater than conventional packaging materials.

Polyethylene (PE) film--


The PE film has a large gas permeability, and as the density increases, its gas permeability is lowered. The PE film has moisture resistance and low moisture permeability. Polyethylene film (PE) can produce low-density, medium-density, high-density polyethylene and cross-linked polyethylene with different properties depending on the manufacturing method and control method.

Low density polyethylene (LDPE):
- Its density is about 0.92g/cm2. Low-density polyethylene film has good transparency and heat-sealing property, can be waterproof and moisture-proof; low tensile strength, large tensile elongation, easy to wrinkle, film of 0.03mm or less, tension control should be small, and tension everywhere It should be constant, especially when heated, it is more deformable, making it difficult to color. Therefore, when drying, the film surface temperature should not be too high (within 550C). According to different film forming processes, it can be divided into blown film (IPE), cast film (CPE), low foaming film and so on. The tensile strength and opening property of IPE film are better than that of CPE film. It can be used as food bag and garment bag for front printing. CPE film has uniform thickness, surface gloss, transparency and heat sealability ratio, PE is good, and can be printed on the front and back. However, the production cost is high; the CPE film is mainly used as the inner layer of the composite bag and the packaging of cosmetics, pickles and cakes; the low foaming film has good decorativeness, thick texture, and is not easy to be stretched and deformed, and is printed on the front side for use as a new year painting and trademark. And hand bags and so on.
