FFS Heavy-Duty Packaging Film Application and Development
Packaging film is the largest application field of LLDPE/LDPE. The packaging film products are used in industrial packaging (such as household appliances, machinery, chemicals, building materials, etc.), agricultural packaging (such as corn straw, alfalfa and other silage), households and supermarkets. What is the packaging of the PE itself?
At present, PE is mainly packaged in paper-plastic compounding bags, woven bags and FFS heavy-duty bags. From the perspective of application ratio, paper-plastic compounding bags account for a relatively small proportion, and some imported materials from Japan and Taiwan Province are packed in this way. Plastic woven bags are mainly used by manufacturing enterprises that have put into production earlier. Since the beginning of the 21st century, as society’s requirements for safety, environmental protection, resource conservation, and cost control have gradually increased, the application of traditional packaging forms has reduced, which provides a good opportunity for the rapid development of new environmentally friendly products.
So what is a heavy-duty bag? According to the classification method of western countries, packaging films that can carry 10-50kg of solid particles or powder materials are generally called heavy-duty packaging films. The so-called FFS is the automatic forming, filling, and sealing. The FFS heavy-duty packaging film is produced by a high-speed automatic packaging machine, which has the advantages of low labor cost, convenient and flexible bag making.
