Embodiment 1

[0035] Embodiment one: by above-mentioned technology, raw material, auxiliary material are pressed,

[0036] In upper surface layer A: Homopolypropylene 97%

[0037] Anti-sticking agent 3%

[0038] In core layer B: Homopolypropylene 98%

[0039] Antistatic agent 2%

[0040] In the lower surface layer C: Homopolypropylene 97%

[0041] Anti-sticking agent 3%

[0042] Mix the selected raw and auxiliary materials separately and mix evenly, then send the uniformly mixed raw and auxiliary materials into the extruder to be plasticized into a melt, and the melt is co-extruded through the pipe through the die casting device to form a thick After the thick sheet is stretched longitudinally and transversely by a polypropylene biaxial stretching machine, the thick film is stretched longitudinally and transversely by a biaxial stretching machine to form a film. The thickness of the film is adjusted by an automatic thickness measuring device to reach...

Embodiment 2

[0043] Embodiment two: the raw and auxiliary materials are pressed,

[0044] In upper surface layer A: Homopolypropylene 96%

[0045] Anti-sticking agent 4%

[0046] In core layer B: Homopolypropylene 97%

[0047] Antistatic agent 3%

[0048] In the lower surface layer C: Homopolypropylene 96%

[0049] Anti-sticking agent 4%

[0050] The technique of this embodiment is the same as embodiment one. The base film product produced according to this scheme is suitable for the processing of laser transfer products after pre-coating vacuum aluminum plating.

Embodiment 3

[0051] Embodiment three: raw and auxiliary materials are pressed:

[0052] In upper surface layer A: Homopolypropylene 95%,

[0053] Anti-sticking agent 5%

[0054] In core layer B: Homopolypropylene 96%

[0055] Antistatic agent 4%

[0056] In the lower surface layer C: Homopolypropylene 95%

[0057] Anti-sticking agent 5%

[0058] The technique of this embodiment is the same as embodiment one. The base film product produced according to this scheme is not only suitable for the processing of pre-coated vacuum aluminum-coated products for general purposes, but also can be embossed with strong local or overall layering after pre-coated vacuum aluminum-plating.

Abstract

A bidirectionally stretched polypropene film substrate with high aluminum-plating effect, transfer effect and laser effect is composed of upper surface layer, core layer and lower surface layer, which are combined through heat fusing and co-extruding. It is prepared from cheap homopolypropene. Its preparing process is also disclosed.

Description

Technical field: [0001] The invention relates to a polypropylene base film and a preparation method thereof, belonging to a vacuum aluminized laser biaxially stretched polypropylene base film and a preparation method thereof. Background technique: [0002] At present, the known transfer base film used to produce laser imprinted evaporation products is a base film produced from heterogeneous polypropylene (PP) materials such as polyester plastic (PET), polyethylene (PE), etc. Embossing evaporation and laser transfer of the film can finally achieve the decoration, decoration or anti-counterfeiting effect on the packaged goods. However, the raw materials used in the production of this type of base film are expensive, the equipment performance requirements are high, and the production cost is high. The post-processing cost is high, and due to the influence of the production scale, it is impossible for ordinary users to directly emboss it. In this way, it brings insurmountable de...
