Abstract
The utility model discloses a liquid packaging bag which comprises a bag body and a bag mouth arranged on the bag body. The bag body is formed by an outer-layer bag and at least one inner-layer bag arranged in the outer-layer bag, and cavities are arranged between the outer-layer bag and the inner-layer bags and between every two adjacent inner-layer bags; the outer-layer bag and the inner-layer bags are connected into a whole at the bag mouth, the outer-layer bag is formed by a surface layer and a bottom layer, and the surface layer and the bottom layer can be connected through an adhesion layer or connected through heat-seal pressing. According to the liquid packaging bag, by adopting the outer-layer bag and at least one inner-layer bag to form the bag body structure, lubricity, abrasive resistance and gas barrier property of the bag body can be effectively improved, tensile strength and tear strength can be enhanced, and static electricity can be prevented; because the cavities are arranged between the outer-layer bag and the inner-layer bags and between every two adjacent inner-layer bags, tensile force caused by outside extrusion can be effectively buffered, and frictional resistance can be reduced.
Description
Technical field
The utility model relates to a kind of packaging bag, particularly a kind of pack for liquids.
Background technology
Existing flexible package punch mainly uses plastic bottle, Plastic Drum or other containers to carry out can or barreled, but Plastic Drum or bottle are put heap and are covered according to larger space, the downthrust process easily deforms owing to holding capacity is poor or causes cut, simultaneously for the packing of importing and exporting liquid type, traffic cost is relatively high, and very easily reveals and cause environmental pollution.
The pack for liquids of the food such as beverage, drinks, cooking oil and seasonings has appearred on the market much being used in, these packaging bags are the monolayer package bag, although lighter than traditional can or barreled packaging quality, footprint area is little and be convenient to store transportation, but in long term storage or use procedure, because the individual layer bag has relatively poor tensile strength and peel strength, wear resisting property and gas barrier properties are low, break easily or rise bag and the defective of leak liquid, in addition, repeatedly also can produce electrostatic phenomenon behind the wipe contact, make troubles to the user.
The utility model content
Has the single bag body structure in order to overcome existing pack for liquids, its tensile strength and peel strength are low, resistance to abrasion and gas barrier property are poor and the defective such as static occurs easily, the purpose of this utility model is to provide a kind of pack for liquids, the bag of this pack for liquids has bilayer or multi-layer film structure, lubricity, resistance to abrasion and gas barrier property that can the Effective Raise bag, strengthen tensile strength and peel strength, prevent the generation of static, simultaneously, cavity between layers can effectively cushion because the extraneous tension force that brings, the capable of reducing friction resistance of pushing.
For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of pack for liquids, comprise bag and the sack that is arranged on the bag, described bag is to be made of outer bag and the nexine bag of being located at described outer bag inside, is provided with cavity between described outer bag and the described nexine bag, and described outer bag and described nexine bag connect as one in described sack place.
Further, described outer bag is to be made of top layer and bottom.
Further, described top layer is the film that adopts the PET plastics to make, and described bottom is the film that adopts the PE plastics to make.
Further, described bag is to be made of outer bag and a plurality of nexine bag, is provided with cavity between described outer bag and the described nexine bag and between the described nexine bag nexine bag adjacent thereto.
Further, be provided with adhering layer between the edge of the edge on described top layer and described bottom.
Further, the edge of the edge on described top layer and described bottom is connected as a single entity by High frequency heating.
Preferably, described outer bag and described nexine bag can be square or bullets.
Further, described sack is arranged at side or the upper end of described bag.
The utility model beneficial effect is: the utility model adopts outer bag and at least one nexine bag to consist of Bag structure, because outer bag is to be made of the bottom that the top layer of adopting the PET plastic sheeting to make and employing PE plastic sheeting are made, so that bag had both had good tensile strength, peel strength and stronger percentage elongation, have again good lubricity, prevent the generation of static; In addition, be provided with cavity between outer bag and the nexine bag and between the nexine bag nexine bag adjacent thereto, not only can effectively form buffering, and reduce friction coefficient, strengthened resistance to abrasion and gas barrier property.

The specific embodiment
Below in conjunction with Fig. 1 to Fig. 4, and further specify the technical solution of the utility model by following examples.
Fig. 1 is the structural representation of embodiment 1 pack for liquids, Fig. 5 is the structural representation of the outer bag of pack for liquids, such as Fig. 1 and shown in Figure 5, a kind of pack for liquids that present embodiment provides, comprise bag and the sack 3 that is arranged on the bag, described bag is to be made of outer bag 1 and the nexine bag 2 of being located at outer bag 1 inside, be provided with cavity 7 between outer bag 1 and the nexine bag 2, the existence of inside and outside layer bag and cavity 7 structures is not only played certain buffer action to the liquid that fills in the nexine bag 2, and the coefficient of reducing friction, strengthen resistance to abrasion and gas barrier property.
Described outer bag 1 is to be made of top layer 4 and bottom 6, it is shaped as square, described top layer 4 is the films that adopt the PET plastics to make, described bottom 6 is the films that adopt the PE plastics to make, wherein, the PET plastic sheeting is a kind of water white transparency and glossiness film, it has good air-tightness and mechanical characteristics, stronger toughness, tensile strength and impact strength, so that the bag that utilizes this plastic sheeting to make had both had good tensile strength, peel strength and stronger percentage elongation, have again good lubricity, prevent the generation of static.
Be provided with adhering layer 5 between the edge of the edge on described top layer 4 and described bottom 6, both bonding connections, the edge on described top layer 4 be connected the edge of bottom 6 and also can connect by High frequency heating.Described sack 3 is arranged at the side of described bag, and described outer bag 1 and described nexine bag 2 connect as one in described sack place.
