Classification of the use of PE stretch film

There are three main ways to use PE stretch film:

First, the hand wrapped film: This is mainly by manual packaging, manual winding film generally has lower requirements for quality, the weight of each roll is generally around 4KG, 5KG, to facilitate the operation;

Second, the machine wrap film: machine wrap film using mechanical packaging, mainly by the movement of the goods to drive the roll to pack, the film tensile strength requirements are relatively high, there is a certain requirement for the film stretch rate, The general stretch ratio is required to be 300%, and the product has a coil weight of 15KG;

Third, machine pre-stretch wrap film: This type of wrap film is mainly used for mechanical packaging. When packing, the packaging machine first stretches the stretch film to a certain ratio, and then wraps the wrap film around the goods to be packaged. The resilience of the goods tightens the goods, and the product quality is high, with high tensile strength, elongation and puncture resistance;

Fourth, we often use colored film: blue, red, yellow, green, black, the manufacturer uses the goods to package the goods while distinguishing the products, which is convenient for identifying the goods;

Five, small PE winding film, convenient for manual packaging, small parts products, such as: hardware, electronics, etc., light weight, good quality! The article comes from
