Abstract

The utility model discloses an it easily tears notched valve port bag to have, including the bag body, outer valve port paper, inlayer PE membrane valve port, tree lace, the bag body constitute by outer bag and inner bag, outer valve port paper and inlayer PE membrane valve port use the tree lace bonding to be in the same place, a bag body valve port department be provided with and easily tear the tangent line, exchange and tear the tangent line and surely go out by dedicated serration sword, guarantee that the valve port can not break off, exchange and tear the tangent line and be located between inlayer PE membrane welding seam and the tree lace, generally, the utility model discloses have the modern design, make simply, not with the help of any instrument, only need just can tear the valve port bag along easily tearing the tangent line with the hand, make the inner bag separate simple easy operation rapidly with outer bag.

Description

A kind of have the valve bag easily tearing otch

Technical field

This utility model belongs to packaging bag technical field, relates to a kind of valve bag, and a kind of have the valve easily tearing otch Pocket.

Background technology

Valve bag, is commonly called as being sticking bag, for current international popular packaging bag, feeds from top or bottom valve port, uses special Filling apparatus, dresses up cube after fill material, heap bag is neat, attractive in appearance.Valve bag is many by multiwall kraft outer bag and inner layer PE film Bag composition, use carry out fill containing the valve bag of inner layer PE film bag time, need the valve port of inner layer PE film bag and outer layer paper The valve port of bag is bonded together, it is ensured that valve port and material filling mouth coordinate smooth and easy.But in some industry, such as food processing industry, do not allow In food production workshop, paper products occur, so to be departed from from outer layer paper bag by inner layer PE film bag.At present, many use shears etc. Sharp instrument cuts valve bag oral area, makes inner layer PE film bag depart from from outer layer paper bag, the most easily valve port is torn, Er Qierong Destructible inner layer PE film bag damages materials inside, it addition, aritificial cut-off is not straight, affects attractive in appearance.

Summary of the invention

The purpose of this utility model is to provide a kind of valve bag having and easily tearing otch, and this has the valve bag easily tearing otch, Modern design, is simple to manufacture, and easily tears tangent line by designing one on bag, and effectively solution inner layer PE film bag and outer layer paper bag are not Segregative problem.

The purpose of this utility model is achieved in that a kind of valve bag having and easily tearing otch, including bag, outer layer valve port Paper, inner layer PE film valve port, tree lace, described bag is made up of outer bag and inner bag, described outer layer valve port paper and inner layer PE film valve Mouth uses tree lace to be bonded together, and is provided with and easily tears tangent line at described bag valve port.

The described tangent line that easily tears is cut out by special serration cutter, it is ensured that valve port will not disconnect.

Described easily tears tangent line between inner layer PE film weld seam and tree lace.

This utility model produces and provides the benefit that: a kind of have the valve bag easily tearing otch, outer layer valve port paper and internal layer PE Film valve port uses tree lace to be bonded together, and during with valve bag material filling, owing to there being the existence of tree lace, material will not enter inner bag with outer In the interlayer of bag, after material filling completes, valve bag is carried out heat sealing, at inner layer PE film valve port, form weld seam.By easily Tear tangent line to be produced between inner layer PE film weld seam and tree lace, the most just can directly tear valve bag with hands, internal layer PE Film bag departs from from outer layer paper bag and comes, and does not interferes with the intact degree of inner layer PE film.

Detailed description of the invention

Below in conjunction with the accompanying drawings to embodiment further instruction of the present utility model.

Embodiment 1

As shown in accompanying drawing 1-2, a kind of have the valve bag easily tearing otch, including bag 1, outer layer valve port paper 3, inner layer PE film valve Mouth 4, tree lace 5, described bag 1 is made up of outer bag and inner bag, and described outer layer valve port paper 3 and inner layer PE film valve port 4 use glue Line 5 is bonded together, and is provided with and easily tears tangent line 6 at described bag valve port 2.

The described tangent line 6 that easily tears is cut out by special serration cutter, it is ensured that valve port 2 will not disconnect.

Described easily tears tangent line 6 between inner layer PE film weld seam 7 and tree lace 5.

This utility model is in use: a kind of have the valve bag easily tearing otch, in the manufacturing process of valve bag, by PE film Inner bag is nested in kraft paper outer bag, and inner layer PE film valve port is bonded on outer layer valve port paper by blend compounds line, then at special mill Cut out on tool and easily tear tangent line.After charging, valve bag is carried out heat sealing, after making inner layer PE film weld seam be positioned at and easily tear tangent line Portion.When using materials inside, it is only necessary to tear valve bag with hands at tangent line easily tearing, inner bag and outer bag just can be made to separate, And due to the existence of inner layer PE film weld seam, can guarantee that the closure of PE inner membrance, do not make materials inside be contaminated.

Generally, this utility model has modern design, is simple to manufacture, not by any instrument, it is only necessary to hands along Easily tear tangent line and just can tear valve bag, make inner bag and outer bag rapidly separate, simple to operation.

Claims

1. there is the valve bag easily tearing otch, including bag, outer layer valve port paper, inner layer PE film valve port, tree lace, described bag Being made up of outer bag and inner bag, described outer layer valve port paper and inner layer PE film valve port use tree lace to be bonded together, it is characterised in that: It is provided with at described bag valve port and easily tears tangent line.

The most according to claim 1 a kind of have the valve bag easily tearing otch, it is characterised in that: described easily tears tangent line by specially Serration cutter cut out, it is ensured that valve port will not disconnect.

The most according to claim 1 a kind of have the valve bag easily tearing otch, it is characterised in that: the described tangent line that easily tears is positioned at Between inner layer PE film weld seam and tree lace.
