Abstract

The utility model relates to a sterile pillow of non-seal paper-based aluminum-plastic composite material, and the sterile pillow is characterized in that the non-seal paper-based aluminum-plastic composite material consists of an outer PE layer, paper, a conglutinating layer, aluminum foil, an inner PE layer and an obstructing layer. The conglutinating layer is arranged on one surface of the aluminum foil, the paper is arranged on the other surface of the conglutinating layer, the outer PE layer is arranged outside the paper, the inner PE layer is arranged on the other surface of the aluminum foil, the obstructing layer is arranged in the middle of the conglutinating layer; one end of each of the outer PE layer, the obstructing layer, and the inner PE layer extends and is heat melted into a sealing layer. The sterile pillow of non-seal paper-based aluminum-plastic composite material has the advantages that vertical sealing can be directly realized without using a seal, accordingly the production process is simpler, the production cost is lower, and the production material can be saved more.

Description

The aseptic pillow of seal free paper base aluminium plastic composite material

Technical field

The utility model relates to the aseptic pillow of a kind of seal free paper base aluminium plastic composite material, relate in particular to a kind of use paper substrate aluminium plastic composite packaging material, through mechanical means with the liquid form product involution of commerce sterilization in the form pillow packs box of a constant volume, pollute again preventing, thereby produce sterile product, belong to aseptic packaging pillow technical field.

Background technology

At present; common aseptic pillow as shown in Figure 1; paper substrate aluminium plastic composite packaging material 1 is introduced with web form; sealing band 2 adheres to a side of wrapper internal layer through heat seal; be shaped through paper web then; tube sealing; can; horizontal sealing; a series of processes such as cut-out; realized the liquid form product involution of sterilization is arrived in the form pillow packs box; with paper side cut place heat-sealing protection; to reach paper layer section leak free purpose; pack employed paper substrate aluminium plastic composite material; as shown in Figure 2, by outside PE layer 3; paper 4;

bonding coat

5 and 7; aluminium foil 6 and inner PE layer 8 are formed, and the two sides of aluminium foil 6 is provided with

bonding coat

5 and 7; another side at bonding coat 5 is provided with paper 4; the outside of paper 4 is provided with outside PE layer 3, is provided with inner PE layer 8 at the another side of bonding coat 7, and each layer of section on its both sides comprises that paper 4 all is not closed.

From aseptic pillow forming process as can be known, need use sealing band with packing both sides overlapping part adhesive seal when longitudinal sealing, sealing band mainly contains following two functions: strengthen the joint of vertical envelope and prevent that product from touching the ply of paper of packing.Bring following deficiency and defective thus:

1, use vertical sealing label bar to increase productive costs;

2, use vertical sealing label bar to make packaging process complicated;

3, when changing sealing band, cause certain production waste of material.

Summary of the invention

The purpose of this utility model provides a kind of sealing band that do not use just can directly realize longitudinal sealing, thereby makes production process simpler, and productive costs is cheaper, produces the aseptic pillow of seal free paper base aluminium plastic composite material that material is more saved.

For realizing above purpose, the technical solution of the utility model provides the aseptic pillow of a kind of seal free paper base aluminium plastic composite material, it is characterized in that, by the direct overlapping heat seal of body sealing layer of seal free paper base aluminium plastic composite material one side.

Described seal free paper base aluminium plastic composite material is made up of outside PE layer, paper, bonding coat, aluminium foil and inner PE layer and barrier layer, the one side of aluminium foil is provided with bonding coat, another side at bonding coat is provided with paper, the outside of paper is provided with outside PE layer, another side at aluminium foil is provided with inner PE layer, centre at bonding coat is provided with barrier layer, and outside PE layer, barrier layer and inner PE layer one end extend and the thermal synthesis sealing layer.

Described sealing layer width is the 1-10 millimeter.

The utility model has been cancelled vertical sealing label bar, directly packing both sides overlapping part is bonded together, eliminated the otch section of packing, vertical envelope place only deposits a lapped seam at the internal layer of aseptic pillow, after packaging material is introduced from paper roll, directly can carry out paper web and be shaped, can finish the packing of aseptic pillow product again through processes such as tube sealing, can, horizontal sealing, cut-outs, therefore improve the quality of vertical envelope.

The utility model utilizes various heat-sealing plastic resins to have interlayer heat seal performance, with outside PE layer, barrier layer and inner PE layer one end extend and the thermal synthesis sealing layer, thereby the paper section is tightly sealed in sealing layer, has only high molecula resin film on the section of packaging material of the present utility model limit, and there is not the paper substrate section, can form an effective barrier layere pollutes preventing again, also can prevent the intrusion of light and oxygen, guarantee that its edge does not seep water, oil, so just can intercept the infiltration of bacterium and liquid and ooze out, therefore thoroughly stop packed article and paper substrate direct contact, in pouring process, do not re-used sealing band and can direct overlapping heat seal system box or bag.

The utility model has the advantages that and do not use sealing band just can directly realize longitudinal sealing, thereby make production process simpler, productive costs is cheaper, produces material and more saves.
