Description

A kind of visualizing liquid packaging bag

Technical field

The utility model relates to a kind of packaging bag, a kind of visualizing liquid food bag or daily chemical product packaging are particularly related to Bag.

Background technique

Existing bag for containg liquid food or daily chemical product mostly used greatly in packaging it is bottled or canned, it is at high cost, need Storage, transport space it is big, freight charges are higher.In order to reduce production, transport and selling cost, more and more enterprise's selections are soft Packaging, i.e. packaging bag, existing pack for liquids often use two panels plastic foil to press edge or with adhesive bonding shape At four flanging or adhesion side, as shown in Figure 1, each plastic foil be by be arranged from the inside to surface heat-sealing shading layer 10, it is intermediate thoroughly Bright layer 20 and surface printing layer 30 form, and are bonded together between each layer by adhesive layer 40, wherein heat-sealing shading layer is using cream The PE material of white, intermediate transparent layer use two-way stretching polyamide film (BOPA), and transparent printing layer is poly- pair of biaxial tension Ethylene terephthalate film (BOPET) or two-way stretching polyamide film, the pack for liquids inner layer of this structure are heat Photosphere is blockaded, the liquid in packaging bag can not be shown that user can not accurately know packaging bag by sealing shading layer Interior liquid capacity can not also hold the capacity that liquid is poured out, cause greatly to perplex to consumer in use.Such as By force if milky 10 uplifting window of heat-sealing shading layer, the intracorporal liquid of bag can be contacted directly with adhesive layer fruit, make liquid Penetrate into adhesive layer 40, thus make sack generate layering, influence using.

In view of this, the designer designs not attain for aforesaid liquid package construction improves caused many missings And it is inconvenient, and deeply conceive, and actively research improvement has a fling at and develops and design the utility model.

Utility model content

There is provided the purpose of the utility model is to overcome the deficiencies in the prior art it is a kind of it is at low cost, hold convenient for observation liquid Measure and facilitate the visualizing liquid packaging bag of control liquid flow capacity.

In order to achieve the above objectives, the solution of the utility model is:

A kind of visualizing liquid packaging bag forms bag body by least piece of plastic film sealing, and the plastic film includes The transparent heat-sealing layer that is set gradually outside by inner, intermediate shading layer and surface printing layer, transparent heat-sealing layer and intermediate shading layer it Between and intermediate shading layer and surface printing layer between respectively by adhesive layer be adhesively fixed, it is right on the intermediate shading layer Answer bag body front or the back side at least one be equipped with a form, the side of form is equipped with graduation indication line.

Further, the form is arranged between the top surface of bag body and bottom surface.

Further, the top surface and bottom surface of the form perforation bag body.

Further, the transparent heat-sealing layer is PE material, and the intermediate shading layer is milky BOPET material, described Surface printing layer is transparent BOPET or BOPA material.

Further, the graduation indication wire tag is on surface printing layer or intermediate shading layer.

Further, the visualizing liquid packaging bag is sealed by piece of plastic film is end to end.

Further, the visualizing liquid packaging bag is sealed by the four sides superposition of two panels plastic film.

After adopting the above structure, the packaging bag of the utility model visualizing liquid is compared to existing structure, by intermediate shading layer It is arranged between transparent heat-sealing layer and surface printing layer, and opens up form on intermediate shading layer, scale is arranged in the side of form Index line, in this way, consumer can intuitively find out liquid in the packaging bag when buying the visualizing liquid packaging bag by form Capacity no longer needs to find capacity marking on the surface printing layer of packaging bag.Importantly, the utility model is regarded due to setting Window, user when in use, clear, accurately can know that the liquid capacity in packaging bag can also hold liquid in use The capacity that body is poured out, consequently facilitating using.Since the outside of transparent heat-sealing layer is arranged in intermediate shading layer, hindered among this Photosphere opens up window and will not have an impact to the liquid in transparent heat-sealing layer.

Fig. 1 is the structural schematic diagram of existing pack for liquids plastic foil.

Fig. 2 is the structural schematic diagram that existing pack for liquids opens up window in internal layer.

Fig. 3 is the appearance diagram of the utility model.

Fig. 4 is the structural schematic diagram of the utility model plastic film.

Specific embodiment

In order to which the technical solution of the utility model is explained further, below by specific embodiment come to the utility model into Row elaborates.

As shown in Figures 3 and 4, the utility model discloses a kind of visualizing liquid packaging bag, thin by least piece of plastic The sealing of film 1 forms bag body 100, for example, the end to end heat-sealing of piece of plastic film can be formed, or by two panels plastic film four Face, which is overlapped mutually and is sealed, also can be obtained bag body 100.

As shown in figure 4, the plastic film 1 includes the transparent heat-sealing layer 11, the intermediate shading layer that set gradually outside by inner 12 and surface printing layer 13, between transparent heat-sealing layer 11 and intermediate shading layer 12 and intermediate shading layer 12 and surface printing layer 13 it Between respectively by 14 be adhesively fixed of adhesive layer, the front or the back side of bag body 100 are corresponded on the intermediate shading layer 12 At least one is equipped with a form 121, and the side of form 121 is equipped with graduation indication line 122, that is to say, that the bag body 100 Form 121 perhaps can be set in the back side in front setting form 121 or open up form 121 on front and the back side.Form 121 setting can be there are two types of form, and one is form 121 to be arranged between the top surface and bottom surface of bag body 100, (upper and lower side is not Connection), another kind is the top surface and bottom surface that form 121 is penetrated through to bag body 100, i.e., intermediate shading layer 12 is by 121 1 points of form Two, the graduation indication line 122 can mark on surface printing layer 13 or intermediate shading layer 12.

Wherein, the transparent heat-sealing layer 11 can be PE material, and PE material is that a kind of crystallinity is high, nonpolar thermoplastic resin Rouge has good chemical stability, can resist the erosion of most acid, alkali, organic solution and hot water, can preferably into Row heat-sealing, therefore its heat-sealing as innermost layer to realize bag body 100.The intermediate shading layer 12 is milky BOPET Material has fabulous wearability, folding resistance, pinhole resistance, tear resistance antistatic property, according to the physical characteristic of BOPET, Certain intensity and stiffness can be provided for bag body 100 as intermediate shading layer, improve the quality of bag body 100.And surface prints The transparent BOPET or BOPA material of brush layer.

The packaging bag of the utility model visualizing liquid opens up form 121, the side setting of form 121 on intermediate shading layer 12 Graduation indication line 122, in this way, consumer can intuitively find out the packaging by form 121 when buying the visualizing liquid packaging bag The capacity of liquid, no longer needs to find capacity marking on the surface printing layer of packaging bag in bag.Importantly, the utility model Since form 121 is arranged, user when in use, can clear, accurately know the liquid capacity in packaging bag, in use process In, the capacity that liquid is poured out can be also held, consequently facilitating using.Since the outer of transparent heat-sealing layer 11 is arranged in intermediate shading layer 12 Side, therefore shading layer 12 opens up form 121 and will not have an impact to the liquid in transparent heat-sealing layer 11 among this.

The product form and style of above-described embodiment and schema and non-limiting the utility model, any technical field The appropriate changes or modifications that those of ordinary skill does it all should be regarded as the patent category for not departing from the utility model.
