Abstract
The utility model relates to a plastic packaging membrane and wrapping bag thereof, it has first protective layer, first tie coat, printing layer, aluminize layer, second protective layer, second tie coat and a seal to interior outside from in proper order, a polyurethane resin is adopted on printing layer, a wrapping bag, and it includes packaging film, first banding and second banding, the first side and the second side of packaging film overlap and connect, constitute a both sides open -ended cavity, first banding is located the first opening part of cavity, seals this first opening part, the second banding lies in cavity second opening part, after this cavity is put into to the thing, seals this second opening part, because polyurethane resin does not have benzene and does not have ketone, has avoided the injury to the human body, can reduce the smell simultaneously, additional first tie coat in outside and first protective layer on the printing layer, so will print the layer and keep apart in inside, improve the intensity on this printing layer, guarantee the anticreep nature on this printing layer, it is firm, durable.
Description
Technical field
This utility model relates to packaging field, particularly to a kind of plastic packaging film and packaging bag thereof.
Background technology
Packaging bag refers to the sack for packing various articles for use, makes goods convenient transport in producing the process of circulation, easily stores.
Present packaging film device printing layer is the mode of employing table print, and the ink made with polyamide oils and fats prints, and this makes user when use changes packaging film, and polyamide oils and fats contains benzene and ketone, and its abnormal smells from the patient is heavier, and poisonous to human body；Additionally, the mode of table print allows this printing layer intensity difference, easy to fall off, thus be not durable.
Utility model content
In order to overcome the deficiency of background technology, this utility model provides a kind of plastic packaging film and packaging bag thereof.
This utility model be the technical scheme is that a kind of plastic packaging film, and it has the first protective layer, the first tack coat, printing layer, aluminium coated, the second protective layer, the second tack coat and sealing the most successively, and described printing layer uses polyurethane resin.
Described first protective layer uses thin film.
Described second protective layer uses thin film.
Described first tack coat uses resin.
Described second tack coat uses resin.
A kind of packaging bag, it includes packaging film, the first edge sealing and the second edge sealing, the first side of described packaging film and second side are overlapping and connect, constitute the cavity of a both-side opening, described first edge sealing is positioned at cavity the first opening part, closes this first opening part, and described second edge sealing is positioned at cavity the second opening part, after thing puts into this cavity, close this second opening part.
The beneficial effects of the utility model are: this utility model is due to polyurethane resin benzene-free ketone-free, it is to avoid injury to human body, can reduce abnormal smells from the patient simultaneously；Add the first tack coat and the first protective layer in the outside of printing layer, so printing layer is isolated in inside, improves the intensity of this printing layer, it is ensured that the anticreep of this printing layer, firm, durable.
Accompanying drawing explanation
Fig. 1 is the schematic diagram that each layer of this utility model is constituted.
Fig. 2 is the schematic diagram that this utility model the first edge sealing and the second edge sealing do not seal pressure.
Fig. 3 is the schematic diagram after this utility model the first edge sealing and the second edge sealing envelope pressure.
1-the first protective layer, 2-the first tack coat, 3-prints layer, 4-aluminium coated, 5-the second protective layer; 6-the second tack coat, 7-sealing, 8-packaging film, 9-the first edge sealing, 10-the second edge sealing; 11-first side, 12-second side, 13-cavity, 14-the first opening part, 15-the second opening part.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model embodiment is described further:
As shown in the figure; a kind of plastic packaging film; it has first protective layer the 1, first tack coat 2, printing layer 3, aluminium coated the 4, second protective layer the 5, second tack coat 6 and sealing 7 the most successively; described printing layer 3 uses polyurethane resin; due to polyurethane resin benzene-free ketone-free; avoid the injury to human body, abnormal smells from the patient can be reduced simultaneously；Add the first tack coat 2 and the first protective layer 1 in the outside of printing layer 3, so printing layer 3 is isolated in inside, improves the intensity of this printing layer, it is ensured that the anticreep of this printing layer, firm, durable.
Described first protective layer 1, described second protective layer 5 all use thin film, and the ruggedness of thin film is good, damages the most easily.
Described first tack coat 2, described second tack coat 6 all use resin, waterproof, firm and nontoxic, especially when as packaging for foodstuff, the safest.
A kind of packaging bag, it includes packaging film the 8, first edge sealing 9 and the second edge sealing 10, the first side 11 of described packaging film 8 and second side 12 are overlapping and connect, constitute the cavity 13 of a both-side opening, described first edge sealing 9 is positioned at cavity 13 first opening part 14, close this first opening part 14, described second edge sealing 10 is positioned at cavity 13 second opening part 15, after thing puts into this cavity 13, close this second opening part 15, this kind of packaging bag can realize assembly line work, it is achieved full-automatic operation, is greatly improved speed of production.
Being only preferred implementation of the present utility model above in association with the embodiment described by accompanying drawing, and not restriction to protection domain of the present utility model, any improvement done based on this utility model spirit all ought to be within this utility model protection domain.
