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. During the use process, a few customers will reflect stretch. There is a phenomenon that the film is broken, and many customers will think that the quality of the stretch film is caused by changing the production 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 stretch film's edge 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, both sides should be rolled up 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 product trays are tightly wrapped together, which can effectively prevent the joint dislocation of the products during transportation. The moving, at the same time, the elastic stretching force can make complex products cling and soft products tighten, especially in the tobacco and textile industries with packaging effects.

 

Stretch film has high tensile strength, significant elongation, flexibility, and high transparency. It can be widely used in the centralized packaging of various goods. Stretch film is sticky on one side and can be stretched and tightly wrapped around the packaged items to store them in storage. It will not be scattered, damaged, or polluted during transportation. At the same time, due to its high transparency, it can be easily identified and reduce distribution errors. It is also convenient for containerized storage and transportation, especially 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 of 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 permeability. The amount of gas permeation at constant temperature determines the breathability of stretch film. It is also possible to use the test to set up the high-pressure chamber and the low-pressure chamber, test and seal 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, a stretch film must maintain air permeability. Pay attention to the tightness of each system in the working instrument.
