How to use the air ring to adjust the air volume of the blown film machine? Compared with similar equipment, the three-layer co extrusion blown film machine has the advantages of high output, good product plasticization, low energy consumption, and simple operation. It completely solves the problems of edge winding and large edge size in blown film machines, and takes product quality to a new level. This film has the advantages of high transparency, puncture resistance, high toughness, good low-temperature thermal cutting performance, good composite fastness, and good resistance to curling.
This film has good barrier properties, freshness, moisture resistance, frost resistance, oxygen resistance, and oil resistance, and can be widely used in light and heavy packaging. For various fresh fruits, meat products, pickles, fresh milk, liquid beverages, medical supplies, etc., below we will briefly introduce the blown film operation process of the next three-layer co extrusion blown film machine, hoping to be helpful to you.
Wind ring: composed of upper and lower components, as well as auxiliary components such as inlet ducts and fans. The fan sends air into the air duct and air ring, evenly blowing cold air into the mold outlet. The cooling tube breaks the film, and the air ring has a device to adjust the air volume.
