Plastic Ziplock Bag Size Distinction Method

Plastic ziplock bag so many types and sizes, what is the difference?

The first is the plastic self-sealing bag material identification to distinguish. Mainly to indicate the product material, easy to recycle, at the same time as different products have different heat temperature and use restrictions, consumers can also know by this logo is made of what is made of plastic materials, should be In what environment to use.

Furthermore, the use of plastic ziplock bag identification to distinguish. This plastic ziplock bag is mainly used for marking the product range. Such as the use of temperature, plastic ziplock bag can be used in microwave ovens, dishwashers, whether the contact with fatty foods, which are used before the need to be clear.

Plastic self-sealing bags Polyurethane thermal elastomers have high tear strength, usually up to 10 times that of natural rubber. However, the hinge resistance of high temperature, the ambient temperature can be higher than that on the decline. Electrical properties, due to polyamines cheese thermal elastomers have a certain hydrophilic properties, ziplock bag the absorption of small air and water bit insulation decreased. Restricted thermoplastic elastomers are used in high insulation applications except where the diene is described. In most cases, new materials are used as raw materials for injection molding. But for some products with less demanding use, people tend to use recycled raw materials for injection molding. This can reduce costs on the one hand; on the other hand can be recycled plastic materials.
