Description

Easily get, self opening film bag

The utility model relates to plastic film bag, especially a kind ofly easily get, self opening film bag.

Along with the development of commodity market, people buy any commodity on market, and businessman all can provide the service of enthusiasm for the customer, commodity bundle is installed, so that the customer carries.At present, modal manner of packing is that commodity are placed plastic bag.Plastic film bag has substituted the papery packaging bag basically.In people's daily life, plastic film bag is used also more and more widely, as is used for the antistaling film bag in food product refrigeration or when refrigeration; The bag film that preventing when being used for the micro-wave oven heated food done, splashproof is used; And the article handbag that provides for client of each supermarket etc.For satisfying the requirement of conveniently taking, maker is bonded together bag film in a pile usually with a connection mode, and the bag film neat arrangement in order that it both can make in a pile can be convenient for people to again pull with hand at any time get use.Also have with the disjunctor bag film that twines or folding mode is packed, need when use is cut along separating trace.In use there is following defective in the bag film of above-mentioned packing: can pull easily and get though put the bonding bag film of connection mode in a pile, if meet two or many bag films when being pulled together, once shut down many bag films and can cause waste; And twining or the disjunctor bag film of folding mode packing when using, the operation more complicated, it is lack of standardization that bag film cuts, and cuts out bad easily; Hand or instrument contact with bag film in the cutting process, easily bag film are polluted; These two kinds of bag films all exist sack to open inconvenient phenomenon, existing plastic film bag is in order to reduce materials and to be convenient to discarded back degradation treatment, its membranous wall is accomplished the thinnest as far as possible, and thin more easy more being pulled together of membranous wall, all need when the plastic film bag that uses on the therefore present market uses with hand the bag film sack stranding that is pulled together is opened, can be made the sack complete opening with chewing to blow then, so operating nature can pollute bag film.This shows that the manner of packing of existing plastic film bag is unscientific, it can not satisfy people conveniently takes, and does not also meet the requirement of modern to sanitation and hygiene.

The purpose of this utility model is the defective that exists at above-mentioned plastic film bag, provide a kind of take very convenient, fast easily get, self opening film bag.

Of the present utility modelly easily get, self opening film bag, comprise: stack orderly film bag, film bag leaves a bag root, and for cut mark point is connected, it is characterized in that: described film bag skin is compounded with the low density polyethylene films layer one between bag root and the film bag; Stack hot weld point adhesion between each orderly film bag low density polyethylene films layer; Film bag center line opening part top is provided with a shim.

Of the present utility modelly easily get, self opening film bag utilizes the low density polyethylene (LDPE) fusing point low, the difference characteristic of the material melting point of high density polyethylene (HDPE) fusing point height, in hot weld point adhesion mode each the film bag outermost point that stacks is sticked together, the internal layer of every film bag then can adhesion, the point of the outer low density polyethylene films interlayer of each film bag stick in pull when drawing easily separated, therefore, get the surface during film bag pulling, with its back side mutually second film bag sack one side of adhesion by when being avulsed, second bag film sack ripped distortion, the shim that is arranged on the sack top this moment just can import sack, to stop the film bag sack to lose to pull adhesive behind the pulling force, for conveniently take next time.

The utility model is easily got, self opening film bag design science, and is rational in infrastructure, ingenious, extremely easy to use, the film bag that stacks pull in proper order get in, the sack self-opening is very easy to packing into of article, has improved work efficiency greatly.Be particularly useful for shop and large supermarket.

The utility model is easily got, the concrete structure of self opening film bag is provided in detail by the following drawings and embodiment.

Fig. 1 is that a kind of suspension type is easily got, the self opening film bag structural representation;

Fig. 2 is that a kind of bagged or boxed is easily got, the self opening film bag structural representation.

Embodiment 1: can be clear that from Fig. 1, this be a kind of be suspended on conveniently to pull on the hook get easily the getting of use, self opening film bag, described film bag 2 requires to tailor routinely, the bag root 4 that can separate with bag is left at sack 3 positions, be sack 3 positions with bag root 4 between be connected 5 for cut mark point, from Fig. 1 as seen, this routine film bag 2 has three place's cut mark point to be connected 5 with bag between the root 4; Under suspension status, use punching out hanging hole 6 on the bag root 4 of film bag 2 for satisfying film bag 2.The outer center line of described film bag is compounded with low density ethylene rete 1, stacks hot weld point adhesion 7 between each orderly film bag low density polyethylene films layer; Fix a shim 8 on the bag root 4 above film bag 2 sacks 3 center lines, the elongation of this shim 8 surpasses some adhesion 7 positions of film bag 2.

Present embodiment is easily got, self opening film bag is applicable to the market or the commodity of large-scale shopping supermarket are guided and supported packing, easily get, self opening film bag is suspended on the hook, the bottom of film bag is loose shape, pull get first film bag after, the shim 8 that is arranged on the sack top promptly can insert the sack of second film bag automatically, to stop the film bag sack adhesive again of being ripped mouth, by that analogy.The user can insert article in the opening-like film bag easily, can not influence work efficiency for the film bag sack of not opening for the moment again.

Embodiment 2: from Fig. 2 as seen, this be a kind of be applicable to packed, and can conveniently pull and get easily the getting of use, self opening film bag, described film bag 2 requires to tailor routinely, the belt end all leaves the bag root 4 that can separate with bag with sack 3 positions and position, bag bottom, film bag 2 is cut mark point with bag between the root 4 and is connected 5, and from Fig. 2 as seen, having everywhere between this routine film bag 2 and bag root 4, cut mark point is connected 5; For satisfy the purpose that film bag 2 is conveniently taken as existing box-packed napkin paper, film bag 2 is furnished with a hard floor 9, and the bag root 4 of film bag 2 all is fixed on the hard floor 9 by riveted joint or line 10; The outer center line of described film bag is compounded with low density polyethylene films layer 1, stacks hot weld point adhesion 7 between each orderly film bag low density polyethylene films layer; The film bag 2 of said fixing on hard floor 9 is furnished with the packing box that is used for its storage or packaging bag 11, offering one corresponding to 3 adhesion positions of 2 sacks of film bag in it in packing box or the packaging bag 11 pulls and gets window 12, pull the upper edge of getting window 12 shim 8 is set, the elongation of this shim 8 surpasses some adhesion 7 positions of film bag 2.

The film bag that present embodiment is easily got, self opening film bag can be avoided not pulled contacts with extraneous, and its using method and effect are similar to the napkin paper of existing box packing.When first film bag 2 from box or the bag 11 pull get window 12 pull take out after, thereafter the sack 3 of a film bag 2 is taken out of, be arranged on packing box or packaging bag 11 and pull the sack that the shim 8 of getting window 12 places promptly can insert second film bag 2 automatically, to stop film bag 2 sack 3 adhesives again of being ripped mouth, and make it expose to pulling and getting window 12 of box or bag 11, take to make things convenient for the user.By that analogy.
