Description

GPPS aluminum-plated film composite board

Technical Field

The utility model relates to the technical field of packaging materials, in particular to a GPPS aluminum-plated film composite board.

Background

As everyone knows, because corrugated box manufacturing cost is lower, the technology is mature to the environmental protection, so by the wide application in the packing field, present corrugated box encloses into box body structure by the multi-disc cardboard, the cardboard generally includes corrugated paper layer and the base paper layer that is located corrugated paper in situ surface, but current packing box in use discovers that its thermal-insulated heat preservation effect is relatively poor, and dampproofing effect is relatively poor moreover, and the inside water of meeting of carton makes the carton take place to warp easily, influences normal use, leads to the use reliability lower.

SUMMERY OF THE UTILITY MODEL

Technical problem to be solved

Aiming at the defects of the prior art, the utility model provides the GPPS aluminum-plated film composite board, which improves the heat insulation effect, has good moisture-proof effect, can keep the box body from deforming when meeting water, and improves the use reliability.

(II) technical scheme

In order to achieve the purpose, the utility model provides the following technical scheme: the GPPS aluminum-plated film composite board comprises a GPPS foaming layer, wherein a paper base layer is arranged on the outer side of the GPPS foaming layer, an aluminum foil layer is arranged on the inner side of the GPPS foaming layer, and a waterproof layer is arranged on one side, away from the GPPS foaming layer, of the aluminum foil layer.

Preferably, the waterproof layer is made of PET plastic.

Preferably, the edge of the waterproof layer wraps the outer side of the GPPS foaming layer and the paper base layer.

Preferably, a printing layer is arranged on one side of the paper base layer, which is far away from the GPPS foaming layer, and a protective film is arranged on one side of the printing layer, which is far away from the paper base layer.

Preferably, the protective film is made of plastic.

Preferably, the GPPS foamed layer is connected to the paper base layer by adhesive bonding.

(III) advantageous effects

Compared with the prior art, the utility model provides a GPPS aluminum-plated film composite board which has the following beneficial effects:

1. the GPPS aluminum-plated film composite board has the effects of heat insulation and preservation through the GPPS foaming layer, and can emit heat through the aluminum foil layer on the inner side of the GPPS foaming layer, so that the heat insulation and preservation effects are further improved;

2. this GPPS aluminized film composite sheet plays dampproofing waterproof effect through the waterproof layer on aluminum foil layer surface, even meet water and also can keep apart water and GPPS foaming layer and paper base layer through the waterproof layer, prevents that the carton from taking place to warp.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is an enlarged view of a portion of FIG. 1A of the present invention;

in the drawings, the reference numbers: 1. a GPPS foam layer; 2. a paper substrate layer; 3. an aluminum foil layer; 4. a waterproof layer; 5. printing layer; 6. and (5) protecting the film.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-2, the GPPS aluminum-plated composite plate of the present invention includes a GPPS foaming layer 1, a paper base layer 2 is disposed on an outer side of the GPPS foaming layer 1, an aluminum foil layer 3 is disposed on an inner side of the GPPS foaming layer 1, and a waterproof layer 4 is disposed on a side of the aluminum foil layer 3 away from the GPPS foaming layer 1; the GPPS foaming layer 1 has the effects of heat insulation and preservation, and the aluminum foil layer 3 on the inner side of the GPPS foaming layer 1 can emit heat, so that the heat insulation and preservation effect is further improved; waterproof layer 4 through 3 surfaces in aluminium foil layer plays dampproofing waterproof effect, even meet water and also can keep apart water and GPPS foaming layer 1 and paper base layer 2 through waterproof layer 4, prevents that the carton from taking place to warp.

The waterproof layer 4 is made of PET plastic, the edge of the waterproof layer 4 wraps the outer sides of the GPPS foaming layer 1 and the paper base layer 2, and the edge of the composite board is also waterproof through the waterproof layer 4.

One side that GPPS foaming layer 1 was kept away from to paper substrate 2 is provided with printing layer 5 to one side that paper substrate 2 was kept away from at printing layer 5 is provided with protection film 6, can protect printing layer 5 on the paper substrate 2 through protection film 6, protection film 6 adopts the plastics material.

The GPPS foaming layer 1 is connected with the paper base layer 2 through adhesive bonding, firstly, the foaming coating is bonded with the paper base layer 2 through adhesive, then, the foaming coating is subjected to hot pressing foaming through hot pressing to form a foaming layer, and the firmness of connection of the GPPS foaming layer 1 and the paper base layer 2 is ensured.

When the heat insulation and preservation structure is used, the GPPS foaming layer 1 has the heat insulation and preservation effect, and the aluminum foil layer 3 on the inner side of the GPPS foaming layer 1 can emit heat, so that the heat insulation and preservation effect is further improved; waterproof layer 4 through 3 surfaces in aluminium foil layer plays dampproofing waterproof effect, even meet water and also can keep apart water and GPPS foaming layer 1 and paper base layer 2 through waterproof layer 4, prevents that the carton from taking place to warp.

It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
