PE stretch film viscosity debugging method
PE stretch film viscosity debugging method The pe stretch film uses the film's super winding force and retractability to bundle the product into a unit compactly and firmly, without any looseness and separation, and without sharp edges and stickiness, even in unfavorable environments. Damage to the packaging. So how should the viscosity of PE stretch film be debugged? The debugging method of PE stretch film viscosity: A high-quality stretch film should have the characteristics of high transparency, high longitudinal elongation, high yield point, high transverse tear strength, and good puncture performance. The application field is limited since the general single-layer casting cannot achieve single-sided adhesion. Single-layer and double-layer casting are not as extensive as three-layer casting in material selection. The formula cost is also high, so the structure of the three-layer co-extrusion is still ideal. In recent years, with the development of materials...
