Abstract
The invention provides an easily-tearing packaging bag which comprises a bag body. A PE film layer is arranged on the inner layer of the bag body in a covering mode. The bag body is formed by a bag front face, a bag back face, two side faces and a bottom face in a sealing-packaging mode. The side faces of the bag body are double-layer folding layers. The top end of each side face of the bag body is arranged on the inner side of the back side face of the bag body through sealing paper in a sealing mode. A zipper mechanism is arranged at a top end sealing portion of the front side face of the bag body in a sealing mode. The zipper mechanism comprises concave strip paper and convex strip paper. A convex strip is arranged on the convex strip paper. A concave strip groove matched with the convex strip is formed in the concave strip paper. The zipper mechanism and the bag body are sealed, plant fibers are used as an inner layer of the bag body so that safety and non-toxic performance of food can be guaranteed, a pulling strip is made of jagged lines directly so that resources can be saved, waste can be lowered, cost can be lowered, the fact that the sealing performance of the bag body is great through bonding paper, accordingly, labor is saved through the bag, using is convenient, and cost is lowered.
Description
Technical field
The present invention relates to packaging bag field, be specifically related to one and easily tear packaging bag.
Background technology
Packaging bag, for installing edible article or small articles etc., the benefit that uses plastic packaging bag for service life long, save cost, and lightweight.
In prior art, in plastic packaging bag product, sack raw material material is directly buying, the internal layer of packaging bag is covered with PE film, the direct packing foods of this film is often not too safe, in tearing packaging bag, need to use duroplasts tie rod, the skin of sack is pulled open by force by tie rod, after pulling open, can throw away, duroplasts tie rod utmost point difficult degradation like this, seldom or not recycle again, therefore can cause the increase of cost and the increase of production technology, easily cause the pollution of environment and the waste of material simultaneously.
The inner space of general existing packaging bag is less, therefore capacity is less, in the time that not eating up, food can not seal in time, or the sealing effectiveness of sealing is bad, existing plastic fastener pressing be difficult for docking, when hermetically sealed in the junction around packaging bag, easily form bubble and wrinkling, therefore leak tightness is also difficult to ensure.
Summary of the invention
For above problems of the prior art, the invention provides a kind of simple and practical packaging bag of easily tearing.
The present invention is achieved by the following technical solutions:
One is easily torn packaging bag, include bag, bag internal layer is covered with PE film, bag by before bag, after bag, two bag sides and the encapsulation of bag sealing bottom surface form, bag side is double-layer folding layer, and the top of bag side seals by sealed paper on the inner side being arranged on after bag, top seal place sealing before bag is provided with zipper, zipper includes raised line paper and recessed paper, on raised line paper, be provided with raised line, on recessed paper, be provided with recessed the groove matching with raised line;
The sealing below of zipper raised line paper is arranged on bag inner side below, and end sealing is arranged on the inner side before bag before raised line paper, and top also seals on the inner side being arranged on before bag before recessed paper;
Before bag, be provided with a pair of jaggies, and form tie rod between two jaggies, tie rod end is connected with pull handle, forms pull handle line between pull handle and bag;
Junction before raised line paper and bag is higher than the junction before recessed paper and bag, between the junction before the junction of described jaggies before raised line paper and bag and recessed paper and bag.
Further, on PE film inside face, be covered with one deck plant fiber layer.
Further, described raised line is Type B raised line, and described recessed is recessed of the W type that matches with Type B raised line.
Further, the junction of two bag sides and bag front-back is by the sealing of bonding paper, and the junction of bag front-back and bag bottom surface is by the sealing of bonding paper, and the junction of two bag sides and bag bottom surface is also by the sealing of bonding paper.
Further, the material of bonding paper is polyvinylchloride bonding paper, and scribbles tackifier on bonding paper two sides.
Further, tackifier are phenylpropanolamine or ester gum.
Principle of work: when use, by the tie rod forming between two jaggies, pull handle line on bag front-back forms pull handle, jaggies and pull handle line can pull out pull handle easily from bag, and pull out together with the tie rod on before bag, therefore just can be by preliminary the pulling open of mouth of sack, because described jaggies is between the junction of raised line paper and bag leading flank and recessed paper and the junction of bag leading flank, therefore now by raised line and recessed groove separately after, can open bag, can make like this sack ratio in increasing leak tightness be easier to tear, owing to there is no the hard tie rod of existing design, therefore raw material and cost have just been saved, avoid pollution on the environment, when encapsulation, again by raised line and recessed groove extruding, this raised line is Type B raised line, recessed is and recessed of the W type of Type B raised line, in conjunction with being more prone to push in pressing, sealing effectiveness is fine simultaneously, due on medial surface after the bag that is arranged on below bag body sealing place of raised line paper, before raised line, top is arranged on the medial surface before bag, and before the top of recessed paper, be also that sealing arranges on the medial surface before bag, the top seal place of bag front-back is also for sealing arranges, therefore tear from the side after tie rod, as long as open raised line and recessed groove just can have been opened sack, if because the jaggies degree of depth can cause gas leakage too deeply, therefore recessed effect that plays again further sealing of Type B raised line and W type, need to seal at the food of not eating up or small articles simultaneously, sealing effectiveness after sealing is fine,
Foldable layer is opened and can be played the effect that inner space increases, and therefore the volume of bag will become greatly, and capacity can increase; On PE film inside face, be covered with one deck plant fiber layer, can ensure to have avoided PE film directly to contact with food in the time of dispensing bag food, therefore ensured food nonhazardous, safety is relieved; The material of bonding paper is polyvinylchloride bonding paper, make the leak tightness of sack elevated-temperature seal in the time producing fine, and bonding scribbles tackifier on paper two sides, and tackifier are phenylpropanolamine or ester gum, have therefore increased the cohesiveness between bonding paper and bag.
Beneficial effect of the present invention is: adopt the sealing means of zipper and bag, internal layer adopts vegetable fibre to do bag internal layer and can ensure the safety non-toxic of food, directly adopt the tie rod that jaggies makes can saving resource, cut the waste, reduce costs, bonding paper ensures that the leak tightness of bag is very good, and therefore sack more laborsaving is like this more convenient to use and reduce costs.
