With the rise of the logistics industry, stretch film has also been widely used. Stretch film is mainly used for packaging and bundling some scattered items. It has the functions of waterproof, moisture-proof, and anti-corrosion. Reflecting on the phenomenon of stretch film breaking, many customers will think that the quality of the stretch film is caused by changing the production raw materials during the production process. What should we do if the stretch film is improperly handled during the packing process, causing it to break as soon as it is pulled?
How to prevent the hand stretch film from breaking the details are as follows:


When packing, we should pay attention to protecting the edge of the stretch film from being bumped to avoid the phenomenon of edge cracking and quality problems. Also, the perimeter to be cut is neat and even when cutting. When making, should roll up both sides neatly. When making, wash the die head clean so there is no black contamination, and do not drop the burnt plastic into the stretch film.

With the help of the retraction force of the stretch film, the product is wrapped and packaged to form a compact unit that does not take up space so that the trays of the product are tightly wrapped together, which can effectively prevent the products from being misaligned during transportation. With the movement, the elastic stretching force can make the complex products close to each other and the soft products tighten, especially in the tobacco and textile industries, which have a packaging effect.


Stretch film has high tensile strength, significant elongation, good flexibility, and high transparency and can be widely used in the centralized packaging of various goods. It will not be scattered, damaged, or polluted during storage and transportation. At the same time, due to its high transparency, it is easy to identify and reduce distribution errors. It is also convenient for containerized storage and transportation, especially for pallet packaging. It can realize mechanized loading and unloading operations and significantly improve the packaging and transportation speed. This product is mainly suitable for pallet packaging goods, such as electronics, building materials, chemicals, metal products, auto parts, and wires—bundled packaging for cables, daily necessities, food, and other industries.


Generally speaking, the gas permeability and gas permeability coefficient are the leading indicators to measure the permeability. The gas permeability at constant temperature determines the breathability of the stretched film. It is also possible to use the test to set up the high-pressure chamber and the low-pressure chamber, test and sell them separately, and use a pressure gauge to detect the pressure rise and change of the low-pressure chamber. Among them, pay attention to the pressure difference between high and low pressure to ensure that the inspection process is carried out under the pressure difference between the two high and low-pressure chambers. Therefore, to ensure the accuracy of the test data, the stretch film maintains a constant air permeability. Pay attention to the tightness of each system in the working instrument.
