Advantage of 55 layers nanometer wrapping film !
Outer surface: Single viscous, easy to open
Subsurface: Increases toughness
Nano scale layer: Organic combination of high strength and toughness
Intermediate layer: Excellent processing and tensile properties
Nano scale layer: Organic combination of high strength and toughness
Inner surface: Stable viscosity, suitable for low temperature environment
-
Compared with the ordinary co-extrusion film technology to produce a higher number of layers, generally in 2-17 layers.
-
The higher number of layers, the better the physical and mechanical properties of the thin film, mainly reflected in the increase of the elongation into geometric multiples, and can withstand higher load and puncture strength.
-
Because of the production process, it is difficult to achieve complete thickness uniformity, or even in the extrusion process discontinuous situation. And manufacturing costs are high.
