Three layer co-extrusion film blowing machine Performance and Characteristics: 1.Die head is layer type spiral mandrel, continuous 3600 rotation. 2.Screen pack changer design is reliable, safe in operation and change the fitter screen easier. 3.Various functional parts may be installed to the lies, such as length counting device, vertical cutting device, cooling water row pipe, film spreading roller, scrap collecting device. The lines are designed developed by our corporation according to market need, they reach the advanced levels in the 90s, come up with analogous lines in home. The lines can be blown continuous 800/1500mm in fold width 0.08mm in the thickness packaging films, film has good insulation, for instance holding temperature,preserve moisture, waterproof , anti-rain, insulation oxygen, oil resistive, and so used for light and heavy-duty packaging, for example fresh fruits, meat-feeding, salt vegetables, fresh milk, drink.
