Abstract
The utility model relates to the field of packaging technique, but especially relate to a multilayer heat -seal paper packaging material. A but multilayer heat -seal paper packaging material, is including using plain paper as the substrate layer of substrate, and the back of substrate layer be adhesive layer, coextrusion film layer in proper order, and the coextrusion film layer comprises three layer construction, is the three -layer coextrusion film layer that PETG layer, PET layer and PETG layer crowded altogether respectively, and the adhesive layer is bound with one deck PETG layer wantonly mutually. The utility model overcomes the application number is the cost defects of 201610251801.4 disclosed invention materials, the utility model discloses a paper packaging material is under the prerequisite with the efficiency, and is more economical.
Description
Technical field
The utility model is related to packing technique field, more particularly to a kind of multilayer, heat-sealable paper packaging material.
Background technology
Package paper has various, such as wood-free paper, parchment, glassine paper, art post paperboard etc..Different packing materials are to paper
The performance requirements opened is different, emphasizes particularly on different fields, such as transparent, moistureproof, and good print performance, bloom are resistance to tear.
For reaching good printing simultaneously, high protection against the tide is high anti-tear broken, high anti-durable and good bearing, market
The method of upper existing Application No. 201610251801.4 and material are to reach, and meet the Property requirements of the above.But due to master
Want the raw material of the PETG of one of structure expensive, result in the limitation of its product, and cost is raised.
Utility model content
The purpose of this utility model is, there is provided a kind of multilayer heat-sealable paper packaging material, to solve above-mentioned technical problem.
The technical problem solved by the utility model can employ the following technical solutions to realize：
A kind of multilayer heat-sealable paper packaging material, including the substrate layer with common paper as base material, the back side of the substrate layer
For the adhesive layer of application of adhesive, the back side of the adhesive layer is co-extrusion film layer, and the co-extrusion film layer is made up of three-decker, point
Wei not PETG layers (polyethylene terephthalate -1,4 cyclohexane dimethanol ester layer), pet layer (poly terephthalic acid second two
Alcohol ester layer) and PETG layers (polyethylene terephthalate -1,4-CHDM ester layer) co-extrusion three-layer co-extruded film layer,
The pet layer is located in the middle of PETG layers described in two-layer, described in any one layer in the adhesive layer and PETG layers described in two-layer
PETG layers are bonding.
Paper packing material of the present utility model instead of Application No. with PETG layers pet layer and PETG layer coextruded structure layers
PETG layers in 201610251801.4, instead of a part of expensive PETG raw materials with cheap PET raw materials makes product more economical.
The thickness of the pet layer is 0.01mm-0.05mm.
The gross thickness of PETG layers described in two-layer is 0.01mm-0.05mm.The gross thickness of the three-layer co-extruded film layer is
0.02mm-0.1mm。
Adhesive layer made by the preferred water soluble acrylic acid ester adhesive of the adhesive layer.
The front of the substrate layer is printing layer.
Beneficial effect：The utility model overcomes the cost of 201610251801.4 invention disclosed material of Application No. and lacks
Fall into, paper packing material of the present utility model is on the premise of same effect, more economical.
Description of the drawings
Fig. 1 is a kind of structural representation of the present utility model；
A kind of structural representations of the Fig. 2 for the utility model co-extrusion film layer；
Fig. 3 is a kind of concrete structure schematic diagram of the present utility model.
Specific embodiment
In order that technological means, creation characteristic, reached purpose and effect that the utility model is realized are easy to understand, under
Face combines to be specifically illustrating and the utility model is expanded on further.
With reference to Fig. 1, a kind of multilayer heat-sealable paper packaging material, including the substrate layer 1 with common paper as base material, substrate layer 1
Front be printing layer.Adhesive layer 2 of the back side of substrate layer 1 for application of adhesive, the bonding of 2 preferred water-and acrylate of adhesive layer
Adhesive layer 2 made by agent.
With reference to Fig. 2, the back side of adhesive layer 2 is co-extrusion film layer 3, and co-extrusion film layer 3 is made up of three-decker, respectively PETG layers
4th, the three-layer co-extruded film layer 3 of 6 co-extrusion of pet layer 5 and PETG layers, adhesive layer 2 are bonding with PETG layers 4 or PETG layers 6.Pet layer 5
Thickness is 0.01mm-0.05mm.PETG layers 4, the gross thickness of PETG layers 6 are 0.01mm-0.05mm.Three-layer co-extruded film layer 3 it is total
Thickness is 0.02mm-0.1mm.
Embodiment 1：
Using common paper be base material as substrate layer 1, in 1 front printing word pattern of substrate layer, reverse side is coated with cold UV irradiation
Water soluble acrylic acid fat adhesive A forms adhesive layer 2, then the three-layer co-extruded film layer 3 thick with 0.04mm is bonded together, and coordinates bonding
Pressing is carried out under cold ultraviolet light after the adhesion characteristic of agent A and obtains final product paper packing material of the present utility model.
And three-layer co-extruded film layer 3 is constituted for PETG layers 4, pet layer 5 and PETG layers 6, as shown in figure 3, wherein PETG layers 4 with
Adhesive layer 2 is bonded.
Wherein, adhesive layer 2 selects the cold UV irradiation water soluble acrylic acid fat adhesive A of Shanghai Hua Chi companies production, reference
201610251801.4。
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above.One's own profession
