Plastic woven bags, referred to as plastic woven bags, is also a very common kind of packaging in life. Most of the uses of plastic woven bags are used for food packaging. Of course, some of them are used for crops or engineering, which is basically determined by their own materials. After all, food grade packaging bags have to go through strict requirements and checks. After all, they are in direct contact with people, except for problems Sorry for the inconvenience.
The material of plastic woven bag is mainly made of poly (propylene). It is extruded and stretched by the equipment into flat wire, just like the usual wire. In this way, it can be woven, and the rest is made by weaving, weaving and bag making. As mentioned above, food grade and non food grade can be divided into two types according to the materials, namely polyethylene (PE) and polypropylene (PP). The former is toxic, while the latter can package food.
In fact, in the 1930s began to PVC film tensile research, found the production of cutting fiber wire and split film fiber new technology. Through slow research, whether in terms of drawing or remanufacturing speed, the material of plastic woven bags is constantly changing. The development is also rapid. The types of plastic woven bags have become more and more, and the sizes and specifications can be customized according to the requirements.
