The slit stretch film is made of high-quality LLDPE as the base material, do not mix with high-quality tackifiers, and is heated, extruded, cast, and then cooled by chill rolls. It has strong toughness, high elasticity, and Tear, high viscosity, thin thickness, cold resistance, heat resistance, pressure resistance, dustproof, waterproof, single-sided adhesive and double-sided adhesive, etc., can save materials, labor, time, and widely used in papermaking , Logistics, chemicals, plastic raw materials, building materials, food, glass, etc.

Standard thickness of stretch film:
1. Determine the maximum allowable number of microorganisms per unit volume or unit surface area. This method is mainly suitable for anti-mold packaging where the product is very sensitive to microorganisms. The key is to determine the type of product microorganisms and the law of reproduction and growth.

2. Determined according to the maximum allowable water absorption of the packaged product or the maximum allowable dehydration of the product. This method is mainly suitable for the product's moisture-proof packaging design. The key is to calculate the moisture permeability coefficient of the stretch film.

3. Determined according to the maximum allowable oxygen absorption of the packaged product. This method is mainly suitable for barrier packaging of products where the product is very sensitive to oxygen. The key is to calculate the oxygen permeability coefficient of the stretched film.

4. Determined according to the maximum carbon dioxide or oxygen permeability allowed by the stretch film. This method is mainly for the inflatable insurance packaging of the product. Products with declared activity require oxygen insurance or maintain a bright color, as well as high concentration of carbon dioxide. The key to inhibiting the growth and reproduction of microorganisms is to calculate the oxygen permeability coefficient and carbon dioxide permeability coefficient of the stretched film.
