Which goods are suitable for PE stretch film packaging? Guangzhou plastic film wholesale

PE stretch film is an industrial packaging film material with high tensile strength, high elongation, good self-adhesion and high transparency. It can be used for hand-drawn PE film and machine-drawn film, and can be used for collective packaging of various commodities. With the super winding force and flexibility of the PE stretched film, the goods are tightly and firmly bound into a unit, so that the scattered small pieces become a whole, and even under unlucky circumstances, the goods will not relax or separate. The PE stretched film is very thin, without sharp edges and stickiness, so as to avoid damage.

Poor stretch forming effect: Appearance: the stretched film is broken or poorly formed. When it is too high, the heating amount of the heating plate is not good and the heating temperature does not match. The PE stretched film sticks to the heat sealing plate, which increases the haze of the film and makes the stretching forming locally thinner. If the heating temperature is too low, the heating temperature of the film is low and the stretching temperature of the film cannot be reached. After stretching, there are many fractures and the stretching depth is too deep.

In the competitive stretch film shopping mall, the more layers of PE stretch film, the greater the market share. Therefore, the product is changed from 5 layers to 7 layers or 9 layers, and its application advantages are shown by improving functions or reducing costs. As a result, the production equipment of PE stretched film is also developing towards multi-layer and large-scale

The raw materials used in PE stretched film are mostly paper and plastic. Paper is usually made of light and strong paper, and plastics are made of thermoplastic materials such as modified polyethylene. These raw materials are relatively cheap and can be recycled. Stretched film is easy to process and simple to form, so the manufacturing cost is cheaper than other packaging. Ming' an packaging
