Everyone has a characteristic that they want to buy good products when using anything. Taking ordering PE plastic bags as an example, many customers need high-quality PE plastic bags without powder and easy to open. Packaging, a professional flexible packaging manufacturer, will explain what PE plastic bags are, the common types of PE plastic bags and how to choose high-quality PE plastic bags.
Polyethylene bag is made of polyethylene. Polyethylene is a typical thermoplastic, which is a kind of odorless, tasteless and non-toxic combustible white powder. The molded polyethylene resin is extruded and granulated wax particles with milky white appearance. Polyethylene has a melting point of 100-130 ℃ and good low-temperature resistance. It can still maintain good mechanical properties at - 60 ℃, but its application temperature is generally 80-110 ℃.
According to density: PE is divided into LDPE, LLDPE, HDPE, etc.
According to the production process, it can be divided into: PE flat bag, self sealing bag, chain clamping bag, envelope bag, punching bag, hand bag, zipper bag, PE film, etc.
1. The polyethylene flat bag is made by a relatively simple production process. After the machine blows the film, cut it into bags on the bag cutting machine, and seal the bottom.
The self sealing bag is provided with a bone strip when the machine blows the film, which can be manually sealed. Unlike zipper bags, these two kinds of bags are usually easily confused.
3. The zipper bag is made by adding independent bone strips on the PE film. There are indentations on both sides of the bag, but there is no self sealing bag. The printing color of the self sealing bag is less, and the zipper bag can print complex patterns.
The envelope bag has a tongue just like an envelope. Stick a strip of adhesive tape on the tongue and fold it to seal the bag.
5. The punching handbag is punched at the appropriate position on the top of the flat bag to facilitate carrying.
The plastic strip is added on the top of the bag to facilitate the lifting of the bag. This process needs to be completed manually, and the price is relatively high.
