Stretch film is widely used in various industrial packaging, such as machinery, building materials, chemicals, household appliances, etc. agricultural packaging, corn stalks, etc. Household and wet packaging, such as fruit, food, vegetable preservation, etc. And developed from shrink packaging. With the rapid development of my country's economy, stretch film has been widely used, and the demand is also growing rapidly.

 

my country's packaging industry is developing rapidly, and now stretch film has become a popular packaging method in the market. The reason why stretch film is so popular is inseparable from the performance of stretch film.

For example, PIB masterbatch has a slightly sticky appearance after six-flow treatment. Stretched films are generally PE film materials with sticky additives. It can be self-adhesive. Black stretch film is suitable for the outer packaging of valuables and can effectively prevent theft.

Stretch film has the advantages of non-slip, dust-proof, strong, and damage-proof. It is widely used in carton trays, strip building materials, food assembly, glass ceramics, fertilizers, cement, resin materials, fabrics, empty cans, cans and other packaging.

 

After the stretched film edge material is broken, it is cut neatly. If the cut is uneven, it cannot be shipped as a finished product. Including the cargo ends must be neatly wound. There is no black impurities, the die head should be cleaned, the burnt plastic can not fall in, and the edges should be protected when packaging, so as to avoid collisions that will cause the edges to break and cause quality problems. Without edges and corners, the paper tubes must be aligned, not long on one side and short on the other. Leave a standard margin of 1CM on both sides. Minimize the white indentation at the ends and middle of the surface wrinkles.

 

The thickness of the stretch film should be determined according to the type and shape of the goods. Goods have high strength and heavy weight. Stretch film is not a uniform index. As for what kind of stretch film to choose, high strength should be selected, especially the tensile strength and tear resistance of plastic film and the thickness of the film. of.

For example, the stretch rate of 50μm thickness can also be slightly larger, for example, it can reach 150%-170%. For fragile products, food and light-weight products are the opposite. A normal stretched film with a thickness of 1530μm and a stretch rate of 130% should be selected.
