Abstract
The utility model discloses a plastic film filling mouth liquid packaging, including plastic film filling mouth, the bag body and banding, plastic film filling mouth seals the bonding with bag body menstruation heat and constitutes the bag together, the zhou duan of the bag body installs the banding to the welding of this kind of plastic film filling mouth liquid packaging edge sealing is firm, and difficult seepage of packing and manufacturing process are simple, are fit for using widely.
Description
Technical field
This utility model relates to a kind of packaging bag, and specifically a kind of plastic film fill mouth pack for liquids, belongs to flexible package punch equipment technical field.
Background technology
Packaging bag is a kind of package packing supplies for packing all kinds of article, and article have solid, shaped and liquid, is widely used in all trades and professions such as chemical products, medical supplies, food, mechano-electronic.Currently on the market mostly for the packaging bag of packing liquid, including single polyolefin film packaging bag, composite plastic film packing bag, paper-plastic stick film package bag, the fill mouth of packaging bag is generally the PE plastics bottle neck with extension spring or is with valvular PE plastics bottle neck, such PE plastics fill bottle neck at filling liquid, use the liquid in packaging bag and repeatedly a small amount of when pouring out liquid in bag, operate all more convenient.But owing to this injection grade PE fill bottle neck has certain hardness, and when soft bag PE layer seals, often on banding, not prison welding is solid, it is easy to cause that liquid leaks；This PE bottle neck itself occurs the phenomenon of cracking often, or weighs wounded partially owing to firmly inequality is easily caused and seals each reason such as bad and cause that in bag, liquid leaks in the process of filling liquid rear seal-cover.This injection grade PE bottle neck manufacturing process is more complicated, and big by material amount, the cost accounting for whole pack for liquids is higher.
Utility model content
For above-mentioned prior art Problems existing, this utility model provides a kind of plastic film fill mouth pack for liquids, has banding firm welding, and packaging is not easy pressure bias wound and the advantage such as manufacturing process is simple, by optimizing overall structure, meets different instructions for uses.
For achieving the above object, the technical solution adopted in the utility model is: a kind of plastic film fill mouth pack for liquids, including plastic film fill mouth, bag and edge sealing, described plastic film fill mouth constitutes bag with bag together with heat-sealing bonding；The Zhou Duan of described bag is provided with edge sealing.
Further, it can be square or polygon-shaped for stating bag, and front and back outer layer is plastic sheeting, composite plastic film or paper-plastic composite film, also can have 0～2 layer of heat sealable conjunction plastic foil respectively before and after inside it, forms bag then through surrounding heat-sealing.Plastic film used by plastic film fill mouth 1 is polyolefin film or polyolefin composite film, and inner side has heat-sealable.
Further, described plastic sheeting fill mouth 1 is by two panels plastic film lamination, and long limit, both sides, through heat sealing, both ends open, forms the mozzle of a fill for liquid.
Further, described plastic film fill mouth 1 one end heat bonding is at edge sealing, and external uncovered formation fill mouth, fill mouth can be with self-styled slide fastener, can seal after filling liquid；The other end uncovered stretching to forms mozzle in bag.
Further, the mozzle one side that described plastic film fill mouth 1 stretches in bag can with bag a certain inner side heat bonding, and the mozzle of a certain inner side of bag is fixed in formation；Or float in liquid in free shape；Or it is in fill mouth one end in curling shape.
The beneficial effects of the utility model are: the plastic film fill mouth of this kind of plastic film fill mouth pack for liquids is by the longer and narrower plastic film lamination of two panels, both sides long limit heat-sealing, open at both ends, form the plastic film mozzle of a fill for liquid and use, when filled and after making to be finished, plastic film mozzle is in bag under the pressure of liquid, self-sealing, this plastic film fill mouth overcomes existing PE plastic bottle mouth envelope not prison welding, bottle neck easily ftractures, packaging easily pressure bias is hindered and is caused the defect of liquid leakage in bag, and manufacturing process is simple, there is cost advantage, and this kind of plastic film fill mouth pack for liquids banding firm welding, packaging is not easy pressure bias wound and manufacturing process is simple, it is suitable for promoting the use of, it is suitable for promoting the use of.

Fig. 2 is this utility model cross section structure schematic diagram；
In figure: 1-plastic film fill mouth, 2-bag, 3-edge sealing.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described.Obviously, described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
As depicted in figs. 1 and 2: a kind of plastic film fill mouth pack for liquids, including plastic film fill mouth 1, bag 2 and edge sealing 3, described plastic film fill mouth 1 constitutes bag with bag 2 together with heat-sealing bonding；The Zhou Duan of described bag 2 is provided with edge sealing 3.
As optimisation technique scheme of the present utility model: described bag 2 can be square or polygon-shaped, front and back outer layer is unitary plastic thin film, composite plastic film or paper-plastic composite film, also can there is 0～2 layer of heat sealable conjunction plastic foil respectively before and after inside it, form bag then through surrounding heat-sealing；Described plastic film fill mouth 1 is by the long and narrow plastic sheeting overlapping of two panels, and long limit, both sides, through heat sealing, open at both ends, forms fill mouth and the mozzle of a fill for liquid；Plastic foil used by described plastic film fill mouth 1 is polyolefin film or composite membrane, and inner side has heat-sealable；Described plastic film fill mouth 1 one end heat bonding is at edge sealing 3, and external uncovered formation fill mouth, fill mouth can be with self-styled slide fastener, can seal after filling liquid；The other end uncovered stretching to forms mozzle in bag；Its mozzle one side stretched in bag 2 of described plastic film fill mouth 1 can with bag 2 a certain inner side heat bonding, and the mozzle of a certain inner side of bag 2 is fixed in formation；Or floating in liquid in free shape, plastic film fill mouth 1 can self-sealing under the pressure of liquid in bag 2.
As using method of the present utility model: this kind of plastic film fill mouth pack for liquids fill mouth in use is with self-styled slide fastener, mozzle one side and bag 2 a certain inner side heat bonding, form the mozzle being fixed on a certain inner side of bag 2, so, plastic film fill mouth 1 has better seal.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and when without departing substantially from spirit of the present utility model or basic feature, it is possible to realize this utility model in other specific forms.Therefore, no matter from which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes in the implication of the equivalency dropping on claim and scope included in this utility model.Any accompanying drawing labelling in claim should be considered as the claim that restriction is involved.
The above; it is only preferred embodiment of the present utility model; not in order to limit this utility model, every any trickle amendment, equivalent replacement and improvement above example made according to technical spirit of the present utility model, should be included within the protection domain of technical solutions of the utility model.
