Abstract

The utility model discloses a composite packaging membrane for a printing membrane straight plating window. The packaging membrane comprises a printing and aluminizing biaxially oriented polypropylene layer, a biaxially oriented polyethylene glycol terephthalate layer and a composite tape casting polypropylene layer from inside to outside. Compared with the prior art, the composite packaging membrane has the advantages of being high in transparency, clear and accurate in printed patterns and good in stiffness.

Description

A kind of die directly plates the composite package film of windowing

Technical field

The utility model belongs to composite package film, belongs to especially the composite package film of windowing.

Background technology

The existing common packaging film of aluminizing is that all parts of face have aluminizer to hide, and content can't well be showed.

The utility model content

Technical problem to be solved in the utility model provides a kind of die of content of can well showing and directly plates the composite package film of windowing.

The technical scheme of the utility model technical solution problem is: die directly plates the composite package film of windowing, and is respectively from outside to inside printing, the Biaxially oriented polypropylene layer of aluminizing, biaxial tension PETG layer, compound curtain coating polypropylene layer;

Described printing, the Biaxially oriented polypropylene layer of aluminizing are provided with the blank section of demonstration package film content.

Preferred composite package film is 28 μ m printing, the Biaxially oriented polypropylene layer of aluminizing/12 μ m biaxial tension PETG layer/compound curtain coating polypropylene layers of 40 μ m;

Described compound curtain coating polypropylene layer is respectively corona layer, sandwich layer, hot sealing layer from outside to inside.

Preparation method of the present utility model may further comprise the steps:

A) preparation section of bidirectional stretching polypropylene film prints, aluminizes:

B) preparation section of compound cast polypropylene film;

C) compound working procedure

D) divide cutting process;

The preparation section of the described bidirectional stretching polypropylene film that a) prints, aluminizes comprises following operation:

In bidirectional stretching polypropylene film printed design pattern operation, show that at needs the blank parts of content applies water-soluble gloss oil, remainder applies high temperature resistant gloss oil operation, the operation of aluminizing, washes the aluminium operation.

The utility model compared with prior art has the transparency height, and printed patterns is clear accurately, the characteristics that deflection is good.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the structural representation of compound curtain coating polypropylene layer of the present utility model.

In Fig. 1,2,1 is that printing, the Biaxially oriented polypropylene layer of aluminizing, 2 are that biaxial tension PETG layer, 3 is compound curtain coating polypropylene layer; 4 is that corona layer, 5 is that sandwich layer, 6 is hot sealing layer.

The specific embodiment

Below in conjunction with embodiment the utility model is described in detail.
