    First of all, we should fully understand the types of body-fitting films (body-packing films) . From the material point of view, there are mainly PVC, EVA, PE, PET, sarin (brine) and so on. Specific PE (polyethylene) is divided into non-sticky and sticky body-packed packaging films. Sarin film (DuPont Sarin film / Sarin film) is also non-sticky, because its raw materials are imported from the United States, so the English name is surlyn film.

    Secondly, we must fully understand the advantages and disadvantages of various body-fitting films (body-packing films) . PVC is a semi-rigid body-fitting film with high transparency. It has the advantages of low price, low environmental protection performance, and fragility in low temperature environments (below 4 degrees, especially in the north), which may cause damage to the bag and scattered products, thereby losing the protective function of skin packaging. Therefore, for general standard parts, packaging screws, hardware accessories, etc., try not to use PVC skin packaging film (unless the first consideration is low cost). Non-adhesive polyethylene body film can be used in vacuum skin packaging (vacuum protective packaging) of printed circuit boards (PCBs). This product has moderate price, food-grade environmental protection and non-toxicity, high transparency, good vacuum plastic parts molding effect, low temperature resistance (low temperature is not brittle), strong aging resistance, and can play the role of long-term continuous vacuum packaging protection and packaging. Therefore, it is widely used in drills, packaging hardware accessories, saw blades and other hardware tools, lighting accessories, automotive and motorcycle accessories (radiators, brake pads, bearing sleeves, etc.), mold hardware, locks, crafts, stationery, ferrites Magnetic cores, toys, medical supplies, seafood, etc. Frozen aquatic products such as wood, fish and shrimp, pastries such as sushi, and food. PET body film has high transparency and high thermoforming performance, so it is called "non-fragile body assembly packaging film". Mainly used for packaging of large parts, heavy parts and irregular products. Salt film (salt film) has high transparency and tensile properties, but its price is relatively high. Suitable for products with higher packaging value.
