Building materials of packaging bags are: plastic compound bag, multilayer kraft paper bag, color printing woven bag, valve bags, container bags, etc., the color printing woven bag with more, because the cost of appropriate, printed and attractively presented, moisture proof, suitable for a wide range of products the wrapping.
Shanghai Peng Peng plastic packaging plant in the production of building materials with high strength, high resistance to puncture, moisture and dust, anti - static, anti - ultraviolet - aging, non - pollution, environmental protection;
It has solved the problem of storage and transportation for many years, because it is not afraid of rain and sun, high stacking, more saving storage space, so it is widely used in chemical industry, cement, feed, fertilizer and other industries.
Process for making South Peng building material packing bag:
1, M type heavy bags, in the manufacturing process of the four dead were treated separately, so that the material after dumping without residue.
2, through a special process embossing processing, with the formation of two prominent non slip, make the material stacking higher, more save storage space.
3, take a special process, so that the heat seal to form a bump, to increase the strength and firmness of the product.
