Technical Field

The invention is a manufacturing method with excellent low temperature resistance, adsorptivity and skid resistance in the plastic woven bag production industry; the anti-skid film-coated plastic woven bag produced by the technology has the characteristics that the bag can be normally stacked and does not skid in an environment with the temperature of-30 ℃ and under the condition of ice, a tray for containing goods can be normally transported, loaded and unloaded, and the anti-skid effect is better in the normal temperature environment; therefore, the problem that the coating is smooth and difficult to stack when being used in plastic weaving of the coating in the industry is thoroughly solved, and the product disclosed by the patent is more beneficial to environmental protection and recycling.

Background

In the sea fishing freezing package, the plastic woven bag is mainly used, but the frozen seafood is required to be kept in a special environment in the processes of packaging, storing and transporting, a layer of thin ice can be generated on the surface layer of the bag body of a common plastic woven bag at a low temperature, so that the bag is easy to slide and difficult to stack and store, and the anti-slip function of the bag body is maintained by the paper-plastic composite bag which is currently used in the market, but the paper-plastic composite bag cannot be recycled, and the environment pollution is great.

Disclosure of Invention

6. bag making: after coating, the fabric roll is coated with the anti-skid film outside, the polypropylene woven fabric is arranged inside, and the woven fabric roll is sliced, printed and sewn to finally form the high-strength anti-skid coated plastic woven bag;

the high-strength anti-skid film-coated plastic woven bag has the latest basic characteristics as follows:

1) the outer coating of the polypropylene plastic woven bag has excellent softness, extremely strong elasticity and toughness, very good surface flatness and excellent physical fusion dispersibility, so that the adsorption force and the astringency between films are formed, and the super-strong anti-skid property of the outer coating anti-skid plastic woven bag is determined;

2) the high-strength anti-skid film-coated plastic woven bag has a very good anti-skid effect in an environment with a temperature below 30 ℃ below zero, and has a good anti-skid effect when being stacked, inclined, transported, bumpy, loaded and unloaded for use after containing goods;

3) the high-strength anti-skid film-coated plastic woven bag has more ideal anti-skid effect when used at normal temperature, because the surface softness and elasticity of the film are better at normal temperature;

4) the high-strength anti-skid coated plastic woven bag is better than other similar products in chemical resistance, long-term aging resistance and impact resistance due to the use of the special coating material;

5) according to the high-strength anti-skid film-coated plastic woven bag, during coating production, the temperature of each heating part of equipment is lower than that of the common film coating, and electricity can be saved by about 20%, so that the production cost is reduced, and the high-strength anti-skid film-coated plastic woven bag can contribute to energy conservation, emission reduction and environmental protection.
