2 co-extrusion blown film machineProduced films can extend the date of preservation of liquid packaging, make the product storage time longer, because its material is using alloy steel fuselage, through sophisticated processing technology and some special processing, makes the hardness of double-layer co-extrusion blown film machine to achieve a better state, so the double-layer co-extrusion blown film machine is very durable.On the second floor the charging device of plastic co-extrusion blown film machine, we also takes into consideration the factors of winding and change the volume, so we adopt the moment receive a volume, to keep the film tension, make winding and change volume is more convenient.
2 molding method of co-extrusion blown film machine, can according to the forming equipment mouth shape is different, divided into circular mouth die extrusion blowing method, T mouth die LiuYanFa T die rolling method and three categories, which the ring die extrusion molding method is blown film machine's main method.Three methods of type into forming film each have their advantages and disadvantages, choose the crowded blowing mould method advantage is flexible, easy to produce different specifications have good toughness of thin films, and T mouth die LiuYanFa, T die rolling method can improve the production rate, was prepared with accurate film thickness and good Luster properties of film.
