Preferably, coating dry weight incrementss are 2 ± 0.5g/m after the multilayer extrusion print film coating2, it is coated with dry
The consumption of weight incrementss and multilayer extrusion print film is consistent substantially.
Preferably, the weight part ratio of the biological starch hot sealing layer, starch-resin layer and biological starch process layer is 30：
30：40, which makes to form a best proportion relation between three, and has reached saving material and internal layer heat seal strength
Between balance.
Preferably, the multilayer extrusion print film is printed using printing treatment layer and printing base membrane layer as printing basement membrane
Brush, the three-layer co-extruded blown film formed using biological starch hot sealing layer, starch-resin layer and biological starch process layer is as internal warm
Sealing, while being modified to biological starch process layer makes it form preferable adhesive effect with intermediate adhesion layer, finally to place
After the oxygen-containing biodegradable Biaxially oriented polypropylene managed carries out co-extrusion with the biological starch process layer inside inside heat seal layer, lead to
Intermediate adhesion layer is crossed seal.
The advantageous effect that the present invention reaches is：The present invention provides a kind of complete biodegradable multilayer extrusion print films, this is more
The production combination process that layer squeezes out print film has reached the standard of zero release of pollutant, while also ensuring that the multilayer extrusion prints
The possibility that mould is integrally degraded, complete biodegradable multilayer extrusion print film of the invention meet modern article development to packet
The requirement of dress, mechanical strength, heat sealability, heat-sealing temperature, barrier property, Kekelé structure count, resistance tocrocking of the multilayer extrusion film etc. are comprehensive
Performance is closed to be improved significantly, and its processing cost is relatively low, convenient for being widely popularized and applying.
