Abstract
The utility model relates to a plastic packing bag for liquid, which has the structure that a bag body structure which is provided with a front and a rear positive bag surfaces and a left and a right side bag surfaces is formed by a sheet of plastic composite film, the side bag surfaces are dichotomized by a longitudinal inner fold line which is arranged on the side bag surfaces, an inner film of the side bag surfaces and an inner film of the positive bag surfaces are relatively clamped between the two positive bag surfaces by the longitudinal inner fold line, the upper end and the lower end of a bag body are respectively provided with an angle-shaped heat seal surface and a bevel heat seal line which are bonded with the positive bag surfaces and the side bag surfaces, the upper end and the lower end of the bag body are respectively reserved with a bag mouth connecting port and a filling port, the side bag surface which is arranged on the same side as the angle-shaped heat seal surface is correspondingly provided with heat seal holes in the angle-shaped heat seal surface, and the two positive bag surfaces are in heat seal connection with each other in the heat seal holes. The utility model adopts a sheet of plastic composite film to form the packing bag, four longitudinal heat seal sides are matched with the bevel heat seal line which is arranged on the lower end to form a stand-up bag structure which is filled, and same side upper angles of the two positive bag surfaces are connected by the heat seal holes. The utility model has the characteristics of high strength of the bag body; furthermore, the color printing patterns of each surface and the packaging are neat and beautiful, and the utility model is convenient to sale and display by products and use.
Description
Technical field
The utility model relates to packaging bag, is specifically related to a kind of liquid plastics packaging bag, is specially adapted to have color printing sign and can be upright when selling, so that the packing of the liquid substance of commodity displaying.
Background technology
Plastic packaging bag especially for the plastic wrapping body of aqueous material, is convenient to production and processing, transportation and sale and is easy to form exquisite characteristics such as color printing sign with it, obtains use more and more widely.But present liquid plastics packaging bag is commonly simple four banding Bag structures, can not be upright behind the filling liquid, be unfavorable for the displaying of merchandise sales process and the placement when drinking.For overcoming the shortcoming that four banding common plastics pack for liquids can not be upright, but prior art discloses and severally can form the packaging bag of square flat bottomed erect type liquid plastics, but it uses multi-disc composite film heat synthesis type, and the high frequency sealing edges color printing patterns many, each bag face that exist bag to be used for joint are difficult to be consistent, the processing technology complicated problems.In addition, because the corresponding bag of a homonymy angle, upper end is the separation erectility after the packaging bag can, the weak area of intensity when not only becoming packaging bag and using, attractive in appearance in the time of also can influencing packaging bag simultaneously and uprightly place.
Summary of the invention
The purpose of this utility model is at the problems referred to above, and a kind of have upright function, intensity height, neat and artistic liquid plastics packaging bag are provided.
The technical scheme that realizes above-mentioned purpose is: a kind of liquid plastics packaging bag, comprise have at least in, outer double-ply composite plastic film, before it has, two positive bags of faces in back and a left side, the bag of right two side pocket faces is made of at the complex film that side joins a slice, it runs through the square cavity volume structure that four high longitudinal heat seal limits of bag form the bag cross-sectional plane, place two side pocket face centers vertically in take out stitches when bag is stacked state before corresponding being folded in of inner membrance to minute side pocket face and the inner membrance that makes the side pocket face and positive bag face, between the two positive bags of faces in back, before the lower end of bag is provided with the oblique angle hot thread of bonding positive bag face and side pocket face and is formed at, the reservation filling exit of back positive bag face midway location, before the upper end of bag is provided with the dihedral heat seal face of bonding positive bag face and side pocket face and is formed at, the reservation bag mouth communication port of back positive bag face midway location, the corresponding heat seal hole that offers respectively on the side pocket face in homonymy dihedral heat seal face, in the heat seal hole before, back positive bag face heat seal links to each other.
The technical solution of the utility model also comprises: above-mentioned heat seal hole is a circular port; The inner side edge of dihedral heat seal face is arranged to the curved line that reduces pressure.
The utility model adopts a slice composite plastic film to constitute packaging bag, not only helps increasing the bag intensity of packaging bag, also makes the color printing pattern neat appearance of each face of packaging bag; Article four, the oblique angle hot thread configuration structure of longitudinal heat seal limit and lower end forms the square cavity volume with end, flat pattern side after making the packaging bag can, forms naturally stable rising structure; And, both helped increasing the working strength at packaging bag upper corners place by the heat seal hole being set and making that the angle end is connected on the homonymy of two positive bags of faces in upper corners heat seal face, make the moulding on bag top when erectility neat and artistic again.
Description of drawings
Accompanying drawing is the structural representation of this liquid plastics packaging bag when being in stacked state.
The specific embodiment
This packaging bag is applicable to the composite film packaging bag, and its complex film can be the two-layer complex film with envelope inner membrance and color printing adventitia, or is equipped with the multilayer complex films of functional membranes such as enhancing, shading in interior adventitia therebetween.As accompanying drawing, this packaging bag is for before having, two positive bags of faces 1 in back and a left side, the Bag structure of right two side pocket faces 2, constitute at the complex film that side joins by whole piece, its four run through the high longitudinal heat seal limit 3 of bag and make bag form the square cavity volume structure of cross-sectional plane, place two side pocket face centers vertically in broken line 4 when as shown stacked state of bag before corresponding being folded in of inner membrance to minute side pocket face and the inner membrance that makes the side pocket face and positive bag face, between the two positive bags of faces in back, before the lower end of bag is provided with the oblique angle hot thread 5 of bonding positive bag face and side pocket face and is formed at, the reservation filling exit 6 of back positive bag face midway location, before the upper end of bag is provided with the dihedral heat seal face 7 of bonding positive bag face and side pocket face and is formed at, the reservation bag mouth communication port 8 of back positive bag face midway location, the corresponding heat seal hole 9 that offers respectively on the side pocket face in the dihedral heat seal face of homonymy, in the heat seal hole before, back positive bag face heat seal links to each other.
Multiple hole shape can be adopted in the utility model heat seal hole 9 on its side pocket face in heat seal face, and the heat seal hole 9 of accompanying drawing embodiment is a circular port, its have be convenient to process, advantage that the junction bond strength is high.
Dihedral heat seal face 7 integral body of the present utility model are triangular in shape, and the inner side edge of its heat seal face is fit to be arranged to the curved line that reduces pressure, to reduce the suffered filling pressure of packaging bag.The decompression curved line that accompanying drawing embodiment provides is the two concave, convex curved line structures of joining.
As accompanying drawing, when the utility model is specifically implemented, with respect to the oblique angle hot thread base hot thread can be set in the lower end of bag, be used for further improving the reliability of packaging bag base seal.
