Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further details.
As Figure 1-5, packaging bag is easily torn without tear tape in horizontal sealing limit, be made up of packaging bag complex film 11, tear strips 12, flanging 13, polygon profile hole 141, tangent line hole 151, upper sealing limit 14, lower sealing limit 15, left sealing limit 16, right sealing limit 17, polygon profile hole 141 is distributed with in upper sealing limit 14, tangent line hole 151 is distributed with in lower sealing limit 15, in packaging bag complex film 11, front, upper sealing limit 14 is overlapping with the back side, lower sealing limit 15, crossing, bonds, hot melt permeates bar tear strips 12; The midway location of tear strips 12 is distributed with polygon profile hole 141, and there is tangent line hole 151 on both sides, and the summit of polygon profile hole 141 is respectively facing to the end points in tangent line hole, both sides 151, and be arranged as a spaced straight line, the distance at interval is between 1-7mm; Tear strips 12 parallel beneath is distributed with at least one flanging 13, left sealing limit 16 and 17 pairs, right sealing limit bag carry out edge sealing, close up after, tear strips 12 is positioned at packaging bag 1 top.
Concrete, complex film as the material of packaging bag 1 bag, first at the two ends of complex film, punch respectively, produce polygon profile hole 141 and tangent line hole 151, then suppress flanging 13, as required flanging 13 is bonded, hot melt merges, allow two flangings 13 permeate bar flanging 13.Then by the sealing limit upper-lower overlapping at polygon profile hole 141 and place, tangent line hole 151, bonding or heat fusing are a complex film.Afterwards, load article from the side, and seal.This process last, just can realize automatic filler and sealing by package packing machine.
Be positioned over desktop at packaging bag complex film 11, just (table) face on upper sealing limit 14 is overlapping crossing with the back side, lower sealing limit 15, and is complex as sealing limit, namely an above-mentioned said tear strips 12.At this moment, whole complex film side forms a pipe, circle shape.This is different from the packaging bag 1 of sealing in traditional back side, its sealing limit of not protruding.Like this, the packaging bag 1 of making, catches flanging 13 by hand, pulls to reversing sense, realizes the unlatching of sack (tear strips 12).
Key is that it can not weaken the leak tightness of packaging bag 1, and reason is that after upper sealing limit 14 bonds with lower sealing limit 15, thickness increases, and counteracts the problem that on individual plastic film, hole brings wall thickness to reduce, so the sealing property of complex film is not affected.Thus, indirectly play the object of saving material.
Polygon profile hole 141 on tear strips 12 and tangent line hole 151 are distributed on different sealing limits, pullled by reciprocal, can be torn by complex film by actv., and keep opening to be straight line.Meanwhile, tangent line hole 151 adopts spaced cut hole or profile hole, such as: the hole such as triangle, water-drop-shaped, has interval, directive arrangement, can realize the target that tearing notch unlatching is straight line equally.
