plastic woven bag
Plastic woven bags are made of homopolymer drawing grade P, HDPE or LLDPE as raw materials. The film is melted and extruded in an extruder, and then cut into strips, heat-stretched, heat-set into yarn spindles, and then processed by warp and weft. After the machine is woven into a cloth, it is thermally cut into a certain size and sewn into a bag. The annual output of plastic woven bags in my country reaches 500 million standard bags, which is the country with the largest output in the world. www.handern.com PET sheet equipment
The advantages of plastic woven packaging are: first, light weight, huangsu bag is 63g/m, plastic woven bag is 11p/m film heavy packaging bag 232g/m2; second, high tensile strength, abrasion resistance, sturdiness and durability: The tensile strength of the yellow bag is 881176N/m, and the plastic flat yarn is 41～686N/m, which means that the load-bearing capacity of the woven bag is more than twice that of the yellow bag; Corrosion effect, no mildew and moth-eaten, such as lining the woven bag with a film or coating a layer of plastic, it will have good water resistance. Fourth, it is clean and hygienic, easy to clean and recycle. www.handern.com PET sheet equipment
The disadvantages of plastic woven bag packaging are: first, limited heat resistance; PP woven bag heat-resistant 120°C, HDPE80C; first, poor external gloss, long-term stacking outdoors, it will quickly lose strength, especially in Qinghai, etc. In plateau areas, UV absorbers should be added to the raw materials for this purpose: third, the friction factor is small, and the high-rise stacking is prone to sliding. For this reason, when the stackability of plastic woven bags is important in packaging, it should be considered on the surface of the woven bag. Anti-slip treatment: composite kraft paper or composite anti-slip film, etc. www.handern.com PET sheet equipment
The production process of plastic woven bags can be divided into three parts: silk production, weaving and bag making. www.handern.com PET sheet equipment
