What is the tensile strength of the stretched film?

If the stretch film is made of environmentally friendly new materials, the tensile force will be great. Metallocene is added during the production process, one meter can basically pull three meters or more, and it will not break, which greatly reduces the cost of workers in the process of using the machine.

Adhesion after contact between stretched films, during the wrapping process and after wrapping, can make the packaging product fasten without loosening. Self-adhesion is affected by many external factors. Such as humidity, dust and pollutants. There are two main methods for obtaining self-adhesive films. The first is to process a film with a smooth and shiny surface; the second is to use an additive that increases the adhesion to make the surface of the stretched film wet, thereby improving the adhesion.

Stretching is the ability of a stretched film to produce elastic elongation after being pulled. Increasing longitudinal stretching will eventually make the stretched film thinner and shorter in width. Although longitudinal stretching is beneficial, overstretching is often not desirable. Because this will make the stretched film thin and easy to tear, while increasing the tension applied to the package.

Stretch film is an industrial film loading product, which has high tensile strength, large elongation, good self-adhesion and high transparency. It is used for manual stretch film and machine stretch film. It can be widely used in the centralized packaging of various goods.

The stretch film is mainly made by mixing and extruding several different polyene resins. It has puncture resistance, super strength and high performance. It wraps the goods stacked on the pallet to make the packaging more stable and neat. Strong waterproof effect, widely used in foreign trade export, paper making, hardware, plastic chemical industry, building materials, food and medicine industries.

The product is wound and packaged with the stretching force of the stretch film after stretching to form a compact unit that does not take up space, so that the product trays are tightly wrapped together, which can effectively prevent the products from being misaligned during transportation. And moving, at the same time, the adjustable tensile force can make the hard products fit tightly, and make the soft products shrink, especially in the tobacco industry and the textile industry. It has a unique packaging effect.
