When packing, we should pay attention to protect the edge of the tensile film from being knocked, so as not to cause quality problems due to edge cracking. In addition, the edges to be cut should be neat and flat. The two sides should also be rolled neatly when making. During production, the die head should be cleaned and free of black pollutants. Do not drop the burnt plastic into the stretch film.

The product is wrapped and packaged with the help of the retracting force of the stretched film to form a compact, space-free unit, so that the pallets of the product are tightly wrapped together, which can effectively prevent the mutual dislocation and movement of the products during transportation. At the same time, the adjustable tensile force can make the hard products close to each other and make the soft products compact, especially in the tobacco industry and textile industry.

The stretch film has the characteristics of high tensile strength, large elongation, good flexibility and high transparency, which can be widely used in the centralized packaging of various goods. The stretch film has adhesive on one side and can stretch and wrap the packed goods tightly, so that they will not be scattered, damaged and contaminated during the storage and transportation process. At the same time, due to the high transparency, it can be easily identified and reduce distribution errors. It is also convenient for containerized storage and transportation, especially suitable for pallet packaging, which can realize mechanized loading and unloading operations and greatly improve the packaging and transportation speed. This product is mainly applicable to the packaging of cargo pallets, such as electronics, building materials, chemicals, metal products, auto parts, wires and cables, daily necessities, food and other industries.

Generally speaking, the gas permeability and the gas permeability coefficient are the main indicators to measure the permeability. The permeability of the stretched film is determined by the gas permeability at constant temperature. You can also use the test to set up the high pressure chamber and the low pressure chamber, test and seal them separately, and use the manometer to detect the pressure rise and change of the low pressure chamber. Pay attention to the pressure difference between high pressure and low pressure, and ensure that the inspection process is carried out under the pressure difference between the two high and low pressure chambers. Therefore, in order to ensure the accuracy of the test data, pay attention to the tightness of each system in the working instrument to maintain the permeability of the tensile film.
