Description

Multilayer composite packaging material structure

Technical Field

The utility model relates to a packaging material technical field especially relates to a multilayer composite packaging material structure.

Background

With the development of the packaging industry, the packaging materials and styles required by different products are different, and the traditional single paperboard package cannot meet more requirements, for example, when some precise electronic products are packaged, the moisture resistance and the anti-collision buffer performance are both good;

while some existing composite packaging materials generally provide water resistance by being covered with a plastic film, it is inconvenient to ensure the overall water resistance and moisture resistance when the external protection is damaged by friction.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the problems existing in the prior art and providing a multi-layer composite packaging material structure.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a multilayer composite packaging material structure, includes skin and inlayer, the skin is made for the non-woven fabrics, the inlayer is glass fiber board, be provided with sponge layer and cardboard layer between skin and the inlayer respectively, the one end of keeping away from the cardboard layer on the inlayer is connected with the aluminium foil layer.

Preferably, the outer layer is covered with a waterproof film.

Preferably, the sponge layer is made of PU sponge.

Preferably, the paperboard layer is a three-layer corrugated paperboard, the three-layer corrugated paperboard comprises an upper layer and a lower layer, and a wave interlayer is arranged between the upper layer and the lower layer.

Preferably, the outer layer, the sponge layer, the paperboard layer, the inner layer and the aluminum foil layer are bonded by glue.

Compared with the prior art, the utility model has the following benefits:

1. the utility model discloses an outer non-woven fabrics improves the surface abrasion resistance, cooperates waterproof film to play the water-proof effects, even waterproof film and non-woven fabrics take place to wear out scheduling problem, sponge layer and cardboard layer also can provide good water absorption effect, cooperates the aluminium foil layer, also can play good water proof dampproofing effect, guarantees the dampproofing and waterproofing effect of product;

2. the sponge layer is matched with the paperboard layer, so that the water absorption effect can be achieved, the good compression-resistant buffering effect can be achieved, the external impact load can be better absorbed, the inner glass fiber board can achieve the good heat insulation and flame retardant effect, the influence of the temperature on the internal product is reduced, the multilayer composite material can achieve good waterproof, damp-proof and compression-resistant buffering performances, the heat insulation and flame retardant performances can be guaranteed, and the requirements for packaging different products are better met.
