Abstract

The utility model relates to a packaging bag structure, which mainly comprises a bag piece and a bag sealing opening, wherein, the bag piece is a layer of polypropylene (also called CPP) layer which is connected with a cased ink layer and is combined via an adhesive agent layer and a polyethylene (also called PE) layer. The utility model has the advantages that the polypropylene (also called CPP) is free from environmental influence, and the geometric size of the polypropylene is comparatively stable; the new structure has both softness and toughness, the bag breaking rate is reduced, and the waste of contents is also reduced.

Description

The structure of packaging bag

Technical field:

The utility model relates to a kind of structure of packaging bag, particularly a kind of high tenacity and soft package construction that is applicable to the powder packing.

Background technology:

Have many article need use plastic bag packaging in daily life, the structure major part of previously used plastic bag all is by biaxial tension nylon, claims BOPA and polyethylene again, claims PE compound formation again.But the shortcoming of the plastic bag of this structure is more crisp, in bag when filling article or the pocket that is full of article sell and transportation in be squeezed or collision can cause broken bag to cause the waste of product, and biaxial tension nylon BOPA be very easy to absorb airborne moisture content in natural environment and cause film to produce variation on the physical dimension, final itself and the polyethylene of influencing, claim that again PE's is compound, make troubles also can for the printing of ink lay, biaxial tension nylon BOPA cost is higher from cost of product.The purpose of this utility model is exactly in order to address the above problem, and designs a kind of packaging bag of new construction.

Summary of the invention:

Formation of the present utility model mainly comprises: bag sheet and bag seal, and described bag sheet is a cast polypropylene, claims the CPP layer through being printed with a chromatography ink lay again, and this cast polypropylene claims the CPP layer through adhesive phase and polyethylene again, claims that again the PE layer is mutually compound.The utility model has the advantages that: cast polypropylene, claim that again CPP physical dimension not affected by environment is more stable, the soft flexible of cost-cutting, and new construction has greatly reduced the broken bag rate, has also reduced the waste of content.

Fig. 2 is a front view of the present utility model;

Further specify embodiment of the present utility model below in conjunction with accompanying drawing:

Embodiment:

Cast polypropylene claims CPP layer 1 through being printed with a chromatography ink lay 2 again, and this cast polypropylene claims CPP layer 1 through adhesive phase 3 and polyethylene again, claims the PE layer 4 mutually compound formation bag sheet again; With capper the bag sheet is sealed after folding and to seal 7 in the formation, lower sealing 5 and back of the body envelope 6, have two oval-shaped holes 8 of carrying on 7 last sealing.

Claims (2)

1, a kind of structure of packaging bag mainly comprises: bag sheet and bag seal, and it is characterized in that, described bag sheet is a cast polypropylene, claims the CPP layer through being printed with a chromatography ink lay, this cast polypropylene again, claim the CPP layer through adhesive phase and polyethylene again, claim that again the PE layer is mutually compound.

2, the structure of a kind of packaging bag according to claim 1 is sealed on it is characterized in that described bag seals and is had two oval-shaped holes of carrying.
