Abstract
The invention relates to a leakage-proof zipper bag and belongs to the technical field of composite soft packaging. The leakage-proof zipper bag comprises a bag body; the bag body comprises three layers which are a coated biaxial stretching polyester layer, an adhesive layer and a polyethylene layer respectively; a zipper is arranged at the position of an upper opening of the bag body; an insertion sheet is arranged at the position away from the lower part of the zipper by 5 to 10mm; the insertion sheet has a width of 20 to 25mm; one side of the insertion sheet is heat-sealed at one side of the bag body; heat-sealing intensity is 3 to 5N; the other side of the insertion sheet is heat-sealed on the bag body after the bag body is filled with articles; the insertion sheet seals up the opening of the bag body. The leakage-proof zipper bag has a simple structure and is ingenious in design; due to arrangement of the insertion sheet, liquid is prevented from flowing out of the packaging bag; due to the design of the three-layer packaging bag, leakage is further prevented; the leakage-proof zipper bag is convenient to use.
Description
Technical field
The present invention relates to a kind of leakproof zippered bag, belong to composite soft packaging technical field.
Background technology
At present, the kind of packaging bag is varied, and goes for food, the different purposes such as general merchandise.At present, supermarket, what the fresh and prepared food such as food market adopted is all common plastic packaging bag, but because fresh meat, seafood or prepared food has been easy to watery blood after packaging or grease flows out, when article are bought back opening by people time, those watery blood can penetrate packaging bag and flow out, and are easy to all be stained with these spots by the ground in family or table.
Summary of the invention
The object of the invention is the problem easily occurring to leak to solve food pack, providing a kind of structure simple, the zippered bag of the antiseep with one deck easily tore film easy to use.
The present invention adopts following technical scheme: a kind of leakproof zippered bag, comprise bag, described bag comprises three layers, be respectively coating biaxial stretching polyester layer, adhesive layer and polyethylene layer, upper shed place of described bag is provided with slide fastener, below described slide fastener, 5-10mm place is provided with inserted sheet, and described inserted sheet seal is in the side of bag, and heat seal strength is 3-5N.
Further, the wide of described inserted sheet is 20-25mm.
Further, described inserted sheet adopts the bidirectional stretching polypropylene film of one side heat-sealing to make.
Further, the thickness of described coating biaxial stretching polyester layer is 45-55 μm.
Further, the thickness of described polyethylene layer is 12-14 μm.
Further, seal is on bag after filled with articles in bag for the another side of described inserted sheet, and the opening of bag seals by described inserted sheet.
Structure of the present invention is simple, designs ingenious, is arranged with inserted sheet at the slide fastener of packaging bag, inserted sheet can first by the opening inclusion of packaging bag before packaging bag slide fastener closes, prevent liquid thing from flowing out pollution, three layers of packaging bag design leakproof more, easy to use.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Reference numeral: bag 1, slide fastener 2, inserted sheet 3.
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, a kind of leakproof zippered bag, comprise bag 1, bag 1 comprises three layers, be respectively coating biaxial stretching polyester layer, adhesive layer and polyethylene layer, the thickness of coating biaxial stretching polyester layer is 45-55 μm, the thickness of polyethylene layer is 12-14 μm, bag 1 upper shed place is provided with slide fastener 2, below slide fastener 2,5-10mm place is provided with inserted sheet 3, and the bidirectional stretching polypropylene film that inserted sheet 3 adopts one side to seal is made, and width is 20-25mm, inserted sheet seal is on one side in the side of bag, and heat seal strength is 3-5N.Seal is on bag 1 after filled with articles in bag for the another side of inserted sheet 3, and the opening of bag seals by inserted sheet 3.
One side seal of the present invention's inserted sheet 3 in use, on bag 1, opens slide fastener 2, after filled with articles, by the opposite side of the another side seal of inserted sheet 3 at bag 1 opening, opening just seals by such inserted sheet 3, closed zipper, the leakproofness of packaging is better, and liquid materials can not flow out.
