The plastics used to make the film are PVC, PP, PE, etc. The main products are shrink film, cling film, wrapping paper, packaging bags, transparent tape, flat woven bags, flat woven fabrics, etc. Most are used on packaging. Generally, the thickness of the film is about 0.01 mm to 0.08 mm. The molding methods include disk die blow molding and flat die extrusion, and some of the moldings often use longitudinal instantaneous stretching to increase the toughness of the product.
The main equipment for the molding process of these products is the extrusion machine (EXTRUDER), which is produced in a continuous molding process. In the initial production (before printing), in order to meet the required size of the product, it is necessary to cut the excess edge material. , also known as ear materials.
Traditionally, the industry has coiled the scraps into bundles and sold them to the purchaser to make recycled secondary feeds; or homemade recycled pellets for other different products. This kind of recycling method can no longer meet the requirements of modern competitive business management. Because it is not economically viable, the cost is too high. Available "Recycle Now" means:
1. While cutting the film ear material, take it synchronously.
2. After being crushed into a closed pulverizer,
3, immediately with the delivery process,
4. Automatically mix with the quantitative ratio and raw materials to recover the original product. This can improve the problems of traditional recycling, reduce the cost and improve the economic and management benefits.
