Ton bags are convenient for bulk bulk powder materials, and have the characteristics of large volume, light weight, and easy loading and unloading. They are one of the common packaging materials. It is characterized by simple structure, light weight, can be folded, takes up little space when returning empty, and is low in price. General enterprises will use more chemicals and the like. As a good quality ton bag, what is its material?
1. Polypropylene
This is the main material that constitutes the ton bag, which accounts for about 90% of the weight of the whole bag. However, polypropylene materials can be divided into high pressure and low pressure, and in the process of use, the two are basically used in combination. Mainly to consider the angle of its tensile force and service life.
2. Polyethylene
It is generally a thermoplastic resin obtained by polymerization of ethylene. Polyethylene is odorless, non-toxic, feels like wax, and has excellent low temperature resistance (the lowest operating temperature can reach -100~-70°C). High density polyethylene (HIGH DENSITY POLYETHYLENE, HDPE) is commonly known as low pressure polyethylene, and LDPE Compared with LLDPE, it has higher temperature resistance, oil resistance, steam permeability resistance and environmental stress crack resistance. In addition, electrical insulation, impact resistance and cold resistance are very good.
3. Filler masterbatch
This is to be used, because the main material of the big bag contains a certain amount of water more or less during the production process, and adding this kind of filler wood can absorb the water well without producing Water eye, resulting in no pull.
