Description

Double-layer CPP film

Technical Field

The utility model belongs to the technical field of the CPP film and specifically relates to a double-deck CPP film is related to.

Background

The traditional CPP film is only a single layer, and due to the degradable characteristic, the strength of the traditional CPP film is weaker, so that the phenomenon of tensile failure of the CPP film is easily caused, the normal use of the CPP film is not facilitated, and the attractiveness of the traditional CPP film is not enough.

SUMMERY OF THE UTILITY MODEL

The utility model provides a solve the above-mentioned problem of proposing, provide a double-deck CPP film for this reason, include CPP film, lower CPP film and weaving layer. The upper surface and the lower surface of the woven layer are coated with a polylactide layer, a pattern layer is arranged on the upper surface of the polylactide layer of the upper end face, the upper CPP film is arranged on the upper surface of the pattern layer, the lower CPP film is arranged on the lower surface of the polylactide layer of the lower end face, and aluminum plating layers are plated on the upper surface of the upper CPP film and the lower surface of the lower CPP film.

Preferably, the woven layer is formed by weaving conductive fibers, and the woven layer comprises transverse conductive fiber yarns and vertical conductive fiber yarns, and the transverse conductive fiber yarns and the vertical conductive fiber yarns are mutually crossed, overlapped and woven.

Preferably, the surface of the upper CPP film is formed with a corrugated pattern by a rolling process.

Preferably, the surface of the lower CPP film is formed with saw-toothed lines by a rolling process.

Preferably, the upper CPP film, the lower CPP film, the pattern layer and the woven layer are bonded through a polyurethane adhesive.

The utility model has the advantages that: the utility model has the advantages of reasonable design, can effectively strengthen the intensity of CPP film, make the CPP film difficult quilt break, also can increase the pleasing to the eye degree of CPP film simultaneously.

Drawings

The invention will now be described, by way of example, with reference to the accompanying drawings, in which:

fig. 1 is a schematic sectional structure of the present invention;

fig. 2 is a schematic view of the knitting structure of the knitting layer of the present invention;

in the figure: 1. a lower CPP film; 2. upper CPP film; 3. weaving layer; 4. a polylactide layer; 5. a pattern layer; 6. plating an aluminum layer; 7. a transverse conductive fiber; 8. vertical conductive fibers.

Detailed Description

All of the features disclosed in this specification, or all of the steps in any method or process so disclosed, may be combined in any combination, except combinations of features and/or steps that are mutually exclusive.

Any feature of the present specification may be replaced by another equivalent or alternative feature serving a similar purpose, unless expressly stated otherwise. That is, unless expressly stated otherwise, each feature is only an example of a generic series of equivalent or similar features.

A double-layer CPP film as shown in fig. 1 and 2 comprises an upper CPP film 2, a lower CPP film 1 and a woven layer 3. The upper and lower two sides of weaving layer 3 all coat and have one deck polylactide layer 4, are provided with pattern layer 5 on the upper surface of polylactide layer 4 of weaving layer 3 up end, it sets up on pattern layer 5's upper surface to go up CPP film 2, CPP film 1 sets up on the lower surface of polylactide layer 4 of weaving layer 3 lower terminal surface down, all plate one deck aluminize layer 6 on the upper surface of going up CPP film 2 and on the lower surface of CPP film 1 down.

The weaving layer 3 is formed by weaving conductive fibers, the weaving layer 3 comprises a transverse conductive fiber filament 7 and a vertical conductive fiber filament 8, and the transverse conductive fiber filament 7 and the vertical conductive fiber filament 8 are mutually crossed, overlapped and pressed for weaving.

The surface of the upper CPP film 2 is formed with corrugated lines through a rolling process.

The surface of the lower CPP film 1 is formed with sawtooth-shaped lines through a rolling process.

The upper CPP film 2, the lower CPP film 1, the pattern layer 5 and the woven layer 3 are bonded through a polyurethane adhesive.

The pattern layer 5 is arranged in a step-shaped structure, so that the pattern has layering, and the attractiveness of the CPP film is improved.

In the using process, the strength of the CPP film can be enhanced by arranging the braided layer 3, the braided layer 3 is braided by mutually crossing, overlapping and pressing the transverse conductive fiber yarns 7 and the vertical conductive fiber yarns 8, the braided layer 3 can be balanced and stable, so that the braided layer 3 has the function of enhancing the strength of the CPP film fully, and meanwhile, the conductive fiber yarns can also effectively prevent static electricity; the strength of the CPP film can be further enhanced by the aid of the polylactide layer 4; the surface of the upper CPP film 2 is provided with corrugated lines through a rolling process, so that the CPP film has texture; the surface of the lower CPP film 1 is provided with sawtooth-shaped grains through a rolling process, so that the texture of the CPP film can be further enhanced, and the CPP film can have a certain anti-counterfeiting function due to the fact that the grains on the surfaces of the upper CPP film 2 and the lower CPP film 1 are different; the setting of pattern layer 5 can make the CPP film more pleasing to the eye, the setting of aluminizing layer 6 can further improve the pleasing to the eye degree of CPP film.

The present invention is not limited to the foregoing embodiments. The invention extends to any novel feature or any novel combination of features disclosed in this specification, and to any novel method or process steps or any novel combination of features disclosed.
