Abstract

The utility model discloses a paper-plastics bag. The paper-plastics bag comprises a cylindrical bag body formed by weaving the plastic threads, wherein the bag body is composed of continuous inner plastic woven bag layer, and a surface paper layer is compounded on the outer surface of the bag body. Because the bag body is composed of continuous inner plastic woven bag layer, the bag body is not required to be connected by pasting or sewing, and the paper-plastics bag has no longitudinal junction, thereby reducing the manufacture procedure and reducing the production cost; the bag body is not easy to expand or break and has higher structural strength and tensile strength, and the paper-plastics bag is more firm and durable, and has good humidity and moisture resistance and long service life.

Description

A kind of paper plastic bag
Technical field
The utility model relates to the sack technical field, refers in particular to a kind of paper plastic bag.
Background technology
In the prior art; the packaging bag that is used to pack materials such as fertilizer, cement is divided into two kinds of paper bag and Polywoven Bags; for paper bag; paper bag is the bag that single layer paper material is made, and paper bag can be moistureproof, damp proof, still; in transportation and preservation process; paper bag is scratched, is punctured or damaged by pressure easily, and paper bag is damaged easily, and paper bag can not effectively be protected the material that is packaged in the paper bag.
For Polywoven Bag, the bag of Polywoven Bag is to be curled by a rectangular plastic woven cloth to form tubular, and the dual-side of plastic woven cloth couples together by pasting processing or sewing to process, and the side of bag has vertical joint.Though, Polywoven Bag is difficult for being scratched, puncturing or damage by pressure, but, because the fault of construction in the existing Polywoven Bag design, the joint of Polywoven Bag can't bear bigger application force, in use, the joint of Polywoven Bag splits easily or opens cruelly, and Polywoven Bag can't be used.
In addition, there is non-moistureproof, not damp-proof shortcoming in Polywoven Bag.Paper bag and Polywoven Bag respectively have merits and demerits, and therefore, present packaging bag has improved needs.
Summary of the invention
The purpose of this utility model is to provide a kind of paper plastic bag at the deficiencies in the prior art, and paper plastic bag does not have vertical joint, and bag is difficult for being strutted or supportting sudden and violent, and bag has higher structural strength and tensile strength, longer service life.
For achieving the above object, the utility model is achieved through the following technical solutions.
A kind of paper plastic bag comprises and utilizes the plastics silk thread to weave the bag of the barrel shape that forms that bag is the bag that barrel-contoured interior Polywoven Bag layer constitutes, and the bag outside face is compounded with surface paper layer.
Described paper plastic bag also comprises middle PE-PP bonding coat, paper plastic bag comprises surface paper layer, middle PE-PP bonding coat and interior Polywoven Bag layer from outside to inside successively, the outside face of the inside face of surface paper layer and middle PE-PP bonding coat is compound, and the inside face of middle PE-PP bonding coat and the outside face of interior Polywoven Bag layer are compound.
The upper end open of described bag, the lower end closed of bag.
The upper end open of described bag, the lower ending opening of bag.
The beneficial effects of the utility model: the utility model comprises the bag that utilizes the barrel shape that plastics silk thread braiding forms, bag is the bag that continuous interior Polywoven Bag layer constitutes, the bag outside face is compounded with surface paper layer, because bag is the bag that barrel-contoured interior Polywoven Bag layer constitutes, do not need bag to be coupled together by pasting processing or sewing to process, reduce manufacturing procedure, reduce production costs, simultaneously, bag is difficult for being strutted or supportting sudden and violent, and bag has higher structural strength and tensile strength, and paper plastic bag is more sturdy and durable, has good protection against the tide, moisture-proof characteristic, longer service life.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the laminar texture scheme drawing of the paper plastic bag among Fig. 1.
Mark among Fig. 1 and 2 is respectively: 1---bag, 2---the interior Polywoven Bag layer of surface paper layer, 3---middle PE-PP bonding coat, 4---.
The specific embodiment
A kind of paper plastic bag of the present utility model comprises and utilizes the plastics silk thread to weave the bag of the barrel shape that forms that bag is the bag that barrel-contoured interior Polywoven Bag layer 4 constitutes as illustrated in fig. 1 and 2, and the bag outside face is compounded with surface paper layer 2.
In preferred implementation, paper plastic bag comprises the bag that utilizes the drum that plastics silk thread braiding forms, bag be cylindraceous in the bag that constitutes of Polywoven Bag layer 4.
Because bag is the bag that continuous interior Polywoven Bag layer 4 constitutes, paper plastic bag does not have vertical joint, do not need bag to be coupled together by pasting processing or sewing to process, reduce manufacturing procedure, reduce production costs, simultaneously, bag is difficult for being strutted or supportting sudden and violent, bag has higher structural strength and tensile strength, longer service life.
Described paper plastic bag also comprises middle PE-PP bonding coat, and PE is a polyethylene, and PP is a polypropylene, the material layer that middle PE-PP bonding coat 3 is made for the composite material of PE and PP.Paper plastic bag comprises surface paper layer 2, middle PE-PP bonding coat 3 and interior Polywoven Bag layer 4 from outside to inside successively, the outside face of the inside face of surface paper layer 2 and middle PE-PP bonding coat 3 is compound, and the inside face of middle PE-PP bonding coat 3 and the outside face of interior Polywoven Bag layer 4 are compound.Middle PE-PP bonding coat 3 has good adhesive bonding property with surface paper layer 2, simultaneously, middle PE-PP bonding coat 3 has good adhesive bonding property with interior Polywoven Bag layer 4, therefore, by middle PE-PP bonding coat 3 adhesive surface ply of paper 2 and interior Polywoven Bag layer 4 securely, increase the firmness of the combination of paper plastic bag.
Paper plastic bag of the present utility model is combined into one surface paper layer 2 and interior Polywoven Bag layer 4 by middle PE-PP bonding coat 3, make paper plastic bag have the performance of paper bag and the performance of Polywoven Bag simultaneously, have good protection against the tide, moisture-proof characteristic, and structural strength height, paper plastic bag is difficult for being damaged, and paper plastic bag is more sturdy and durable.
The upper end open of described bag, the lower end closed of bag.Make things convenient for the user by the sack article of in bag, packing into, again sack is sealed.
In another better embodiment, the upper end open of bag 1, the lower ending opening of bag 1.The top and bottom of bag 1 are set to opening respectively, make things convenient for the user that sack is carried out secondary processing.
Above content only is preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, the part that all can change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
