Description

A kind of convenient and fast packaging bag in Kaifeng

Technical field

The utility model relates to packaging bag fields, and in particular to a kind of convenient and fast packaging bag in Kaifeng.

Background technique

Packaging bag in life is generally referred to as the internal sack that there is certain space to pack various articles, is easy to article It saves, convenient transportation is widely used among all trades and professions.

Good packaging bag not merely can be well protected content, and user can be facilitated to open and used.What tradition used Packaging bag majority uses film layer, and film layer is usually blow molding, and lateral inflation makes film Layer molecule has lateral orientation, and lateral molecularly oriented will form resistance, and film layer when from longitudinal tear film layer Yield strength is low, and being also easy to produce material stretching causes tearing strength is high-leveled and difficult to tear.Because of composite membrane anisotropy, tension direction is easy to change Become and stress be not easy to focus on a point, in addition the ductility of plastics is good, leads to the thinning deformation of notch, make force dispersion, Power and strand orientation are inconsistent, are difficult to tear out linear type tearing port when tearing packaging bag, cause tearing port excessive, in bag Content spillage be scattered.

Utility model content

The utility model aim is to provide a kind of convenient and fast packaging bag in Kaifeng, can tear out linear type tearing port easily.

The technical solution adopted in the utility model is a kind of convenient and fast packaging bag in Kaifeng, including two bag faces and for sealing Four sealing edges in two bag faces, at least one bag of face of the packaging bag be equipped with one folded to outside the bag face fold Band, it is described to fold band and form twice folding line where it between bag face, it is described to fold band from the first sealing edge to extend to second close Edge sealing, it is described to fold the tearing port being equipped with both ends convenient for tearing.

Preferably, first sealing edge and the second sealing edge are non-conterminous.Folding band is that is extended to from the first sealing edge Two sealing edges, it is bigger by folding the tearing port formed with tearing when the first sealing edge and non-conterminous the second sealing edge.

It is preferably, described that fold band substantially parallel with the adjacent sealing edge of first sealing edge.Fold band with it is therein One sealing edge is not parallel compared to sealing edge in parallel, folds with more beautiful in such design outline, and conveniently The producer carries out the production of repeatability.

Preferably, the film layer in two bag faces of packaging bag is thin by layer of polypropylene foil, polyethylene terephthalate Film layer, polyamide laminate film and aluminium foil layer stack gradually from inside to outside, and adjacent two layers are bonded by adhesive.Polypropylene is thin Film layer, pet film layer, polyamide laminate film and aluminium foil are tape casting film forming layers, are combined in this way Film layer has certain smooth tearing, it is easier to tear out linear tearing port, and blow molding compared with prior art Polyethylene be also equipped with and easily tear, thickness error is small, and glossiness is good, good hand touch and soft advantage.

The adhesive is polyurethane glue.Polyurethane glue has stability as the most commonly used one of adhesive Height, the lesser advantage of environmental pollution, and each film layer can be coupled in sequence

Compared with prior art, the utility model have it is following the utility model has the advantages that

The easily-torn packaging bag of the linear type tearing notch is equipped with one and folds band with tearing port, and user is on the other hand according to bag face Or sealing edge, the other hand pull-up folds band can easily tear packaging bag from tearing port.Because folding band and its place Bag face is formed with twice folding line, and in tearing, this twice folding line can play certain guiding role, and the external force of tearing collects in this It at twice folding line, guides tearing port and extends to sealing edge, and form linear tearing port, such tearing port would not Excessive, the content of packaging bag would not be scattered because tearing partially.

Detailed description of the invention

The utility model is described in further detail with reference to the accompanying drawings and detailed description.

Fig. 1 is the structure chart of the tearing of packaging bag in the prior art；

Fig. 2 be the utility model break a seal convenient and fast packaging bag preferred embodiment front view；

Specific embodiment

As shown in Figure 1, the direction of arrow meaning is tearing direction, packaging bag in the prior art includes bag face 10 and close Edge sealing 11, packaging bag force dispersion when being torn by external force due to tearing, tearing port are easy to tear local derviation and interior items are caused to be scattered.

It is illustrated in figure 2 the utility model to break a seal one of bag face 20 of convenient and fast packaging bag, the surrounding in this bag of face 20 It is as shown in the figure in the sealing edge 21 of 20 two sides of bag face, packaging bag is to contact the one of content equipped with the sealing edge for sealing Face be it is interior, another side is outer.

Bag face 20, which is equipped with from folding one to outside bag face 20 in bag face 20, folds band 22, and folding band 22 is by by bag folding face 20 two layers of film layer forms, and band 22 is folded in figure only it is shown that turning down state upwards.This is folded after band 22 folds naturally Folding line 23 is formd on bag face 20, has another road folding line (not shown) when folding band 22 and turning down downwards.Fold band 22 Since a sealing edge 21, another non-conterminous sealing edge 21 is extended to, sealing edge of the band with its elongated end is folded 21 is substantially vertical, and substantially parallel with the adjacent another sealing edge of sealing edge 21.It is equipped at the both ends for folding band 22 convenient for tearing Tearing port 24,22 both ends for folding band refer to folding the both ends that band 22 extends to sealing edge 21.

As shown in figure 3, the film layer in the bag face 20 of packaging bag is by layer of polypropylene foil 30, polyethylene terephthalate By stacking gradually outside the face Nei Xiangdai of bag face, adjacent two layers pass through poly- ammonia for film layer 31, polyamide laminate film 32 and aluminium foil 33 Ester gum water bonding, naturally it is also possible to bond each film layer using other adhesives, this film layer is formed a film by tape casting 's.

User tears packaging bag from tearing port 23, and tearing port 24 will be torn along twice folding line 23, is formed linear The content of tearing port, packaging bag would not be scattered because tearing partially, in addition the structural property of film layer itself, packaging bag has one Fixed smooth tearing makes the packaging bag of the utility model be easier to tear.

In other some embodiments, two bag faces of convenient and fast packaging bag of breaking a seal, which are equipped with, above-mentioned folds band 22.

Finally it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than the present invention is protected Protect range limitation, those skilled in the art should understand that, can modify to technical solution of the present invention or Equivalent replacement, without departing from the spirit and scope of technical solution of the present invention.
