There are three main ways to use winding film

1、 Manual winding film: This is mainly the way of manual packaging. The manual winding film generally has low requirements for quality, and the weight of each roll is generally about 2kg-5kg to facilitate operation;

2、 Machine winding film: machine winding film adopts mechanical packaging method, which mainly relies on the movement of goods to drive the mold roll for packaging. The requirements for the tensile strength of the film are relatively high, and there are certain requirements for the tensile rate of the film. The general tensile rate is required to be more than 300%, and the coil weight of the product is 15KG;

3、 Machine pre-stretching winding film: this kind of winding film is mainly used for mechanical packaging. When packaging, the packaging machine first stretches the stretching film to a certain proportion, and then winds the winding film on the goods to be packed. The goods are tightly packed by the resilience of the film. The product quality requirements are high, with high tensile strength. The tensile strength generally requires more than 500%, and requires high elongation and puncture resistance;

4、 We often use color film: blue, red, yellow, green, black, which is used by manufacturers to distinguish products while packaging goods, so as to facilitate the identification of goods;

5、 Small winding film, convenient for manual packaging, small parts products, such as hardware, electronics, etc., light weight, easy to use
