Description

Multilayer composite packaging film

Technical Field

The utility model relates to the field of packaging materials, in particular to a multilayer composite packaging film.

Background

The composite film (the multi-layer film is combined together) is a packaging film commonly used at present, and in the embodiment 1 of patent publication CN204384010U, a packaging film is disclosed, and the packaging film is formed by combining multiple layers of different kinds of films through glue adhesion, but both sides (i.e. upper and lower surfaces) of the packaging film are PE films, and the PE film is a material with relatively poor wear resistance, so that the packaging film with the structure is extremely easy to be broken when packaging goods with sharp corners.

Disclosure of Invention

The utility model aims at the problems and provides a multilayer composite packaging film.

The technical scheme adopted by the utility model is as follows:

the utility model provides a multilayer composite packaging film, includes PE membrane, composite film layer, aluminium membrane and PET membrane, PE membrane and aluminium membrane set up on the composite film layer, and PE membrane and aluminium membrane are located the both sides of composite film layer respectively, the PET membrane sets up on the aluminium membrane, and composite film layer and PET membrane are located the both sides of aluminium membrane respectively.

In the packaging film, the aluminum foil and the PET film are compounded on one side of the packaging film, the PET film has stronger wear resistance than the PE film (on the premise of the same thickness), meanwhile, the aluminum film is arranged between the PET film and the composite film layer, the aluminum film has certain stretch resistance, and after the aluminum film and the PET film are compounded together, one side of the whole packaging film has stronger stretch resistance and wear resistance, and the possibility of breakage of the whole packaging film can be reduced when the packaging film is used as a film material. Meanwhile, the aluminum film has good reflection performance on light, so that the whole packaging film has good shading effect.

In summary, the PET film and the aluminum film are added in the packaging film, so that the tensile and anti-friction performance of the whole packaging film is enhanced, and the packaging film has a good shading effect.

Optionally, the PET film is a transparent PET film.

Optionally, the thickness of the PET film is greater than the thickness of the aluminum film.

Optionally, the thickness of the PE film is greater than the thickness of the PET film.

Optionally, the composite film layer includes a woven cloth layer.

The woven cloth layer is arranged to enable the whole packaging film to have good flexibility and further improve the tensile property of the whole packaging film.

Optionally, the composite membrane layer comprises a pearl cotton layer.

The pearl cotton layer is arranged to ensure that the whole film has good heat preservation and insulation performance.

Optionally, the composite film layer includes a PE film layer.

Optionally, the PE film is a PE film.

Optionally, the thickness of the composite film layer is greater than that of the PET film.

Optionally, the thickness of the composite film layer is greater than that of the aluminum film.

The beneficial effects of the utility model are as follows: by adding the PET film and the aluminum film, the tensile and anti-friction performance of the whole packaging film is enhanced, and the packaging film has a good shading effect.
