Summary of relevant knowledge of PE heat shrinkable film

　

1. Protection: This product can be applied to the surface of various products to effectively protect the product from being soiled and scratched during storage, transportation and processing. This product is suitable for various aluminum alloy products, stainless steel products, plexiglass products, furniture, paint panels, mirror panels, alloy panels, various decorative panels, various building panels, etc.

2. Shading effect: When the surface of various products needs deep processing such as spraying and acid etching, the surface that does not need spraying and acid etching needs shading. The shading effect is more important when spraying various colors. The characteristics of shrink film are firm but not firm, and it is firmly attached to the surface of various substrates. After processing, there will be no glue residue and no corrosion.

3. Temperature characteristics: the applicable range is -30 to 70.

4. Moisture resistance: It can be stored and used for a long time in an environment with a relative humidity of 95%.

5. Anti-aging: The anti-aging period of this product is 6 months.

PE heat shrinkable film is suitable for the sales and transportation of various products. It plays a role in firmly covering and protecting products to a certain extent. It is a very important packaging material in our life. At present, this product is popular in the market and has high puncture resistance. The so-called anti-puncture, no matter what kind of sharp things, have a strong penetrating power. PE heat shrinkable film will inevitably have some defects in use. What should I do if there are unknown black spots on the surface of PE heat shrinkable film?

1. Leveling is very important in the whole production process, and it is also the stage we always need to pay attention to. The level is not good, and the post-production effect is not good. Its fluidity is poor, the shape is not uniform, and the color of the aluminized layer is revealed by the ink.

2. The matching degree of ink and adhesive is very important. If the ink and glue do not match. Then to a certain extent, there are rejecters, making it mottled, which is very detrimental to the production effect of the product.

3. Due to the low external tension of the ink, the adhesion between the ink layer and the aluminized layer and the tightness between the layers will decrease unevenly, resulting in black spots.

PE heat shrinkable film is a packaging material, generally used for pallet packaging, and has a fixed shockproof effect. PE heat shrinkable film is a protective film that uses electrostatic adsorption to protect the surface of products, such as electronic manufacturing, building materials, chemicals, metal products, auto parts, wires and cables, papermaking, etc. PE heat shrinkable film has strong buffering ability, good puncture resistance and tear resistance, thin thickness, light material and high cost performance. The pre-stretch rate of PE heat shrinkable film reaches 400%, which can be gathered, waterproof, dustproof and anti-scattering.

If there is a large amount of PE heat shrinkable film, the storage environment is recommended as follows.

1. The storage temperature should not be too high or too low, and should be between -15 and 40 degrees Celsius.

2. When saving, use a reel to store the stretch film. Avoid sun and rain.

3. Refuse to contact with stretch film, acid, alkali or organic solvent, keep the film of stretch film clean and dry.

4. The limited stretch film is not easy to place and should be stored in the warehouse.

5. The stretch film is idle for a long time, so it should be turned over frequently.
