With the development of social economy and the continuous changes in consumption patterns, users have increasingly high requirements for the functionality of film use. The packaging industry is increasingly in need of various types of high functionality and specialized packaging, and single-layer film packaging can no longer meet the increasing needs of the market's packaging level.

Economy, versatility, and high strength are the development trends of the packaging industry, and multi-layer co extrusion coating technology provides good technical support for them. The multi-layer co extrusion method, as a one-time film processing method, avoids traditional post processing processes such as composite and coating, and can effectively reduce production costs. At the same time, the use of multi-layer co extrusion method can combine various polymers with different characteristics in different structures during the extrusion process, giving the film different excellent properties, such as heat sealing, barrier, damage resistance, chemical resistance, stiffness, hardness, etc. In food It has been widely used in fields such as medicine and packaging bags.

Among them, multi-layer co-extrusion heavy bag technology refers to the process of using three or more extruders to melt and extrude various resin raw materials with different functions, such as mPE, HDPE, LDPE, LLDPE, etc., and then composite co extrusion is carried out through a multi channel die. After cooling, shaping, and winding, the final heavy packaging bag with multi-layer structure and comprehensive performance is obtained. Heavy packaging bags can be widely used in raw material bags, rice bags, feed bags, and other fields, with good development prospects.

800 Five-Layer Ffs Line is a film forming vertical line equipment developed by GUANGDONG BAST EXTRUTECH CO., LTD, using multi-layer co extrusion technology. Compared with similar equipment, it has advantages such as high output, good product plasticity, and low energy consumption. The produced finished film has a thicker core layer and thinner surface layer, as well as a sub surface layer that can introduce specific functions in different layers, increasing the adjustability of the equipment and the diversity of the product through the excess number of layers. On this basis, innovative technology has significantly increased the overall output of equipment and the space for enterprises to improve efficiency and reduce costs, which is more in line with the high-speed development needs of the film industry.

Technical parameters of the 800 Five-Layer Ffs Line:
