Application and development trend of film blowing technology
From the point of view of the size of the multi-layer film blowing process has a lot of advantages.
First, the film quality is good; the film here refers to the infusion film, high resistance diaphragm and other high-end films. The small-sized coextrusion equipment produces products with moderate bubble diameter. The cooling effect of the cooling air from the refrigeration unit is the best in this specification, and the surface quality of the finished product is the best, no matter it is traction, rotation or winding up, the surface quality of the finished product is the best, and wrinkles are not easy to appear.
Second, the ratio of performance to price is high; small size equipment is not small. The output of this kind of five layer plane superposition machine head is very large. Through the transformation of die, small size film can be produced. While improving the quality, its output is 1.5 times of that of other similar equipment. It is cheap, low energy consumption, high production efficiency, small frame height, plant height can be reduced The environment is well controlled and can be accepted by more users. Through cost analysis, it can be calculated that if the output of products produced by two small equipment is the same as that of a large equipment, the total cost of such two small equipment is less than that of one large equipment, and the quality of products produced by small equipment is higher than that of large equipment.
Third, it adapts to the process of slitting. If there are too many slits, the winding effect will be affected. At the same time, this kind of equipment can not produce small-sized cylindrical packaging film, such as heavy packaging bags. The small machine can blow any size, any number of layers of cylinder type, cutting type packaging film within the range of 0 ~ 800mm. Without modifying any equipment configuration, it can produce the largest variety of products to meet the diversified requirements of the market. The most important thing is that under this kind of specification and cost, the products have high quality and price, and are invincible in the market competition.
