Abstract

The utility model belongs to the technical field of moisture-preserving and fragrance-preserving packaging materials, and relates to a moisture-preserving and fragrance-preserving packaging material which comprises an aluminum foil layer, a glue layer, a raw paper layer, a glue layer and an aluminum foil layer, wherein the front side and the back side of the raw paper layer are compounded with the aluminum foil layer through the glue layer to form the front aluminum foil layer and the back aluminum foil layer. Aiming at the requirements of a new green environment-friendly trend, the moisture-preserving and aroma-preserving packaging material provided by the utility model abandons the use of a BOPP heat-sealing film in the traditional moisture-preserving and aroma-preserving packaging material, and aims to overcome the defects that a single-layer aluminum foil is insufficient in tension and easy to break in the production and packaging processes, a layer of paper is added to be compounded with the aluminum foil, a layer of heat-sealing gloss oil is coated on the surface of the aluminum foil to achieve the same heat-sealing performance as the BOPP heat-sealing film, and a heat-sealing coating is locally coated on a part needing heat sealing according to the width required by heat sealing, so that the heat-sealing performance is realized, and the energy conservation and emission reduction under the current green environment-friendly trend and the use of plastic films are realized. And the seal-starting temperature of the heat-seal gloss oil is 80 ℃, and the performance of the heat-seal gloss oil is superior to the seal-starting temperature of the common BOPP heat-seal film at 95 ℃.

The technical scheme is that a cigarette lining paper with moisture retention and preservation and a preparation method thereof are provided in the prior art, and the application number is CN 201810049181. The method comprises the following steps: winding the raw paper layer; rolling the PET matte silver composite film; coating a layer of hot melt adhesive on the surface of the PET matte silver composite film in a three-roller extrusion coating mode; unreel raw paper layer to and, the mute silver complex film of PET, will raw paper layer's one side with the mute silver complex film laminating of PET that scribbles the hot melt adhesive forms the slip sheet in cigarette of moisturizing. The cigarette lining paper that moisturizes that this application embodiment shows is through pasting the hot melt sealing layer on raw paper layer, the mute silver complex film of PET to and, the varnish, reaches the effect of moisturizing and keeping fragrance, at the in-process of packing the one side and the tobacco laminating of the mute silver complex film of PET guarantee the moisture in the tobacco, and, other materials do not scatter and disappear, and then reach the effect of moisturizing. The core of the technical scheme in the prior art is also the isolation effect of the PET composite film, so that the cigarette lining paper is kept moist and moisturized, the use of the film cannot be left, and the greening of products cannot be realized.

Therefore, a moisture-preserving and aroma-preserving packaging material is needed to be designed, the structure and the material of the traditional moisture-preserving and aroma-preserving packaging material are abandoned, and the base paper and the aluminum foil are compounded, so that the moisture-preserving characteristic of the traditional moisture-preserving and aroma-preserving packaging material can be realized, a heat-sealing coating is locally coated on a part needing heat sealing according to the width required by heat sealing, the heat sealing performance is realized, and the energy conservation, emission reduction and reduction of the use of plastic films under the current green environmental protection trend can be realized.

Disclosure of Invention

Aiming at the defects in the prior art, the utility model aims to provide the moisture-preserving and aroma-preserving packaging material, which not only can realize the heat sealing performance of the prior art, but also can realize energy conservation and emission reduction under the current green environmental protection trend and reduce the plastic removal of a plastic film.

The utility model provides a moisture-preserving and fragrance-preserving packaging material which comprises an aluminum foil layer, a glue layer, a raw paper layer, a glue layer and an aluminum foil layer, wherein the front surface and the back surface of the raw paper layer are compounded with the aluminum foil layer through the glue layer to form the front aluminum foil layer and the back aluminum foil layer.

In a preferred embodiment of the present invention, the aluminum foil layer is further provided with a heat-sealing varnish layer for subsequent processing.

In a preferred embodiment of the present invention, the aluminum foil layer has a thickness of 0.006-0.0075 mm, preferably 0.0065 mm.
