In what ways do you judge the quality of the body film (body packaging film)?
With the rapid growth of the Chinese economy and the improvement of people's living standards, consumer goods that have entered our daily life are gradually entering our daily life. In what ways do you judge the quality of the body film (body packaging film)? For most manufacturing plants using skin-packaging machinery and equipment, this issue is a very practical and important issue. By selecting a suitable skin-packing film, the cost of packaging materials can be reduced, and the effect of skin-packaging can be guaranteed. Conducive to improving the comprehensive competitiveness of factories and enterprises, has a leading advantage in the market.
Body-fitting film (body-packing film) operation video:
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.

Third, referring to the above selection principles, according to the characteristics of the product and the actual packaging requirements, selecting the appropriate skin-packing film (body-packing film) can reduce the cost of packaging materials and effectively ensure the packaging effect of the product.
The main types of sarin film (DuPont sand shower body film) and how to choose it?
What are the commercial values of sand shower film advantages (advantages of Dupont sarin film) in skin packaging for hardware products ?
Is sarin film (dupont sarin body film, sand shower film) suitable for packaging high-end hardware products?
Dongguan Zhongtang Fengyuan Packaging Products Factory is a well-known domestic manufacturer of sarin film .
Skin-packing process: The transparent skin-packaging film is properly heated and softened and then covered on the product and the bottom plate. At the same time, vacuum suction is enabled under the bottom plate of the close-pack packaging machine. The body-fitting film is adhered to the bottom plate (color printing paper card, corrugated cardboard or foam cloth, etc.)
After the transparent skin packaging film is properly heated and softened, it is covered on the product and the bottom plate, and the vacuum suction is enabled under the chassis. The body-fitting film is formed and stuck on the chassis (color printing paper card, tile edge board or bubble cloth, etc.).
What is the process principle of PET skin packaging film (PET skin film)? PET skin-packing film (PET skin-packing film) is a plastic film used for skin-packaging made of PET plastic material extruded into a film and then coated with hot melt glue.
What is the process flow of PE skin packaging film (PE skin film)? The transparent PE body packaging film (PE body film) is properly heated and softened, and then covered on the product and the bottom plate.
What is the principle of the PVC body packaging film (PVC body film)? The transparent PVC body packaging film (PVC body film) is appropriately heated and softened, and then covered on the product and the bottom plate.
Vacuum body-fitting film ( vacuum body-packing film ) has many advantages to ensure the perfect body-fitting of circuit board magnetic core hardware products: good toughness, resistance to handling and low temperature Good transparency, fresh and bright after packaging.
What are the main features and advantages of vacuum body film (vacuum body film)?
What are the main uses of PET skin pack film ( PET skin pack film )? Hardware products (furniture hardware, decorative hardware, etc.), auto / motorcycle accessories (such as brake pads, gears), measuring tools (drills, saw blades, etc.), stationery, toys, sports equipment / furniture accessories, pneumatic / hydraulic accessories, crafts, Ceramic / Glass products.
