Abstract
The invention relates to the technical field of soft package. A soft packaging bag with a flow channel comprises a bag body, wherein the top part of the bag body is formed by heat-sealing the front wall and the rear wall of the bag body, the top part of the bag body is provided with the long and narrow flow channel which is communicated with the space inside the bag body and is composed of the front wall and the rear wall of the bag body in a heat-sealing manner, and the flow channel opening is heat-sealed. Furthermore, pressing lines consistent with the flow-out direction of an object in the bag body inside the flow channel are arranged on the front wall and the rear wall of the bag body at the flow channel. Furthermore, the flow channel is provided with an easy-to-tear line which is near the flow channel opening. Furthermore, the flow channel is formed by inwards hollowing, shearing and heat-sealing a square bag body. The flow channel formed in the top part of the soft packaging bag body is long and narrow, so that the object in the bag body flows rapidly in the flow channel, and the problem that the object cannot flow out smoothly due to adhesion and sealing of an opening position of a bag body of a common bag body is avoided. The soft packaging bag with the flow channel is suitable for packaging of substitutive package of liquid or powder products.
Description
Technical field
The present invention relates to soft package technology field.
Background technology
Soft packaging bag volume is little, quality is light, convenient transportation, both can packaged solid state article, again can packages for liquid article, and apply very extensive.
Existing soft packaging bag is generally square four edge sealing bags or square Self stand bag, top is right angle, opening mode generally has following several: two right angle heat-sealings at (1) top, need to cut to open a gap with scissors just to make content flow out, but breach is excessive, may make the outflow of content wayward, and when in-built liquid, may be because of the humidification of liquid, indentation, there is bonded together, and content cannot flow out smoothly; (2) top be equipped with lid revolve the hatch frames such as mouth, more conveniently topple over or draw content, can again seal and repeat to open, but cost be higher simultaneously.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of simple in structure, with low cost, and the soft packaging bag that content can flow out smoothly also provides its method for making.
Technical matters to be solved by this invention is achieved by the following technical programs:
A soft packaging bag with runner, comprises bag, and the top of bag is formed by the heat-sealing of antetheca and rear wall, the runner that described bag top is provided with and bag intracorporeal space connects, is comprised of antetheca and the rear wall heat-sealing of bag, and runner mouth seals.
Further, the antetheca of the bag at described runner place and rear wall are provided with the consistent indentation line of outflow direction with runner inner bag content.
Further, described runner is arranging easy tear line near runner mouth position, and described easy tear line is laser cut line or die cut lines or press line.
Moulding is cut out and sealed to described runner by bag top indent.
Described runner is that runner mouth is narrower, the trapezoidal or triangle runner that base portion is wider; Or the parallel parallel fluid channels in two side.
The above-mentioned method for making with the soft packaging bag of runner by step is:
(1) entire volume material is cut into bag body antetheca material and rear wall material, antetheca material and rear wall material are overlapped into a bag body material;
(2) the bag body material after superimposed unreels;
(3) longitudinal, transversal heat seal and cooling, while longitudinally sealing, seals out the shape of runner;
(4) moulding;
(5) output.
Further, when runner need to arrange easy tear line, after step (1), need the bag body material after superimposed in desired location, to carry out laser beam cutting or cross cutting or punching press, form easy tear line.
Further, when the Self stand bag at the bottom of making is with marsupial or penguin bag, in step (1), bag bed material also needs to cut into dimension coiled strip; When step (2) bag body material unreels, bag bed material also needs to unreel simultaneously.
When step (3) longitudinally seals, carry out impression, in runner position, form indentation line.The method of described impression is that shaped steel plate is placed between superimposed bag body antetheca material and rear wall material, the antetheca of shaped steel plate and the desired location of rear wall are provided with symmetrically according to the burr of setting size and shape garland, by the mould with pressure and temperature up and down, push, in runner position, form indentation line.
Further, the described moulding of step (5) is that the bag body that heat-sealing is completed cuts out the profile of bag with forming mould, forms single bag, and this forming mould is preset as the shape of the exterior contour of the bag with runner.
The present invention has following beneficial effect:
(1) the present invention is provided with runner at soft packaging bag bag top, and because runner is long and narrow, bag content flows faster in runner, can not cause bag aperture position adhesion as common bag sealing to cause the problem that content cannot smooth and easy outflow.
(2) antetheca of the bag at runner of the present invention place and rear wall are provided with the consistent indentation line of flow direction with runner inner bag content, can be when producing this soft packaging bag online impression, the indentation line person of being easy to use, by being originally pressed into the round three-dimensional runner of opening for flat runner, facilitates the outflow of content.
(3) the present invention is being provided with easy tear line near runner mouth position, and easily tear line is laser scored line or die cut lines or press line, and customer is without using scissors easily runner to be torn.
(4) moulding is cut out and sealed to runner of the present invention directly by bag front and rear wall, compares the soft packaging bag that revolves the hatch frames such as mouth adding with lid, and cost is lower, and production technology is simpler.
(5) moulding is cut out and sealed to runner of the present invention by bag indent, more saves material, and be conducive to store and transportation.
(6) the present invention is suitable for the packing of the replacement dress of liquid product (as hand cleanser, liquid detergent) or powder product or granular product, by runner design for impression line pressure being the diameter that width after three-dimensional runner is less than the bottleneck of the hard packing bottle that the product of this replacement in filling will inject, tear after easy tear line, flat runner is pressed as after three-dimensional runner, runner is directly inserted in the bottleneck of hard packing bottle, can make product flow into smoothly in hard packing bottle, and do not worry that the outflow of product is wayward and cause product to flow to the problem outside bottle.
