Abstract
The utility model relates to a self-sealing composite paper-plastic bag which comprises a bag body, a paper layer, a woven cloth layer, a plastic film layer and a self-sealing strip. The whole bag is of a square structure, and the middle layer of the bag body is the woven cloth layer. The outer surface of the bag body is the paper layer, and pattern information is printed on the paper layer. The inner surface of the bag body is the plastic film layer. The paper layer and the woven cloth layer are bonded together through a binder in a plastic-coating compaction mode, and the binder is arranged and distributed in a point array. The adjoining plane of the paper layer is uneven, and the plastic film layer is extruded and casted on the adjoining plane of the paper layer to form plastic film layer covering package. The upper end and the lower end of the bag body are glued and press-fitted, and the position near a bag mouth on the surface of the bag body is provided with the self-sealing strip which is formed by combining a convex strip with a concave strip. The self-sealing composite paper-plastic bag has a simple structure, the binder is saved, the cost is reduced, and the self-sealing composite paper-plastic bag is convenient for classified recycling and reuse. The self-sealing package bag can be repeatedly used and is beneficial to saving.
Description
Affiliated technical field:
The utility model relates to a kind of paper-plastic package bag, particularly the compound paper plastic bag of a kind of self-sealing.
Background technology:
The paper-plastic package bag is a kind of package packing supplies that is used for packing freight all kinds, is widely used in the packing of chemical fertilizer, cement, grain, agricultural chemicals, seed, salt, chemical products.Paper-plastic package bag mostly on the existing market, mainly be by between brown paper and Polywoven Bag, being formed by hot melting plastic film bonding, though make brown paper and Polywoven Bag bonding firmly like this, but when recycling, classification is difficult to it is separated, also not environmental protection, and the full wafer of hot melting plastic film distributes and also to have increased cost greatly, causes waste, causes damage to the user.
The utility model content:
At the technical deficiency of existing the said goods, the purpose of this utility model just provides the compound paper plastic bag of a kind of self-sealing, is made up of bag, ply of paper, base fabric, plastic film layers, self-sealed article etc.
The technical scheme that its technical problem that solves the utility model adopts is: whole sack is tetragonal, and the intermediate layer of bag is base fabric, and the outer surface of bag is ply of paper, printing figure line information on the ply of paper, and the inner surface of bag is plastic film layers; Be bonded to one through the plastic-coated compacting by binding agent between ply of paper and the base fabric, binding agent is the dot matrix arranged distribution; The composition surface of ply of paper is uneven, and plastic sheeting is extruded curtain coating and formed plastic membranous layer covering packing on the composition surface of ply of paper; The bag gluing pressing in two ends up and down is provided with self-sealed article near the sack position on the bag surface, and self-sealed article is to be made by raised line and recessed combination.
The utility model beneficial effect: simple in structure, not only saved binding agent, reduce cost, convenient classification is reclaimed again and is utilized, and the packaging bag of self-sealing can be used repeatedly, is conducive to save.
Accompanying drawing is described:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model bag;
Fig. 3 is the structural representation of the utility model self-sealed article;
Among the figure, 1, bag, 2, ply of paper, 3, base fabric, 4, plastic film layers, 5, self-sealed article.
The specific embodiment:
As shown in drawings, the utility model is made up of bag 1, ply of paper 2, base fabric 3, plastic film layers 4, self-sealed article 5 etc., whole sack is tetragonal, the intermediate layer of bag 1 is base fabric 3, the outer surface of bag 1 is ply of paper 2, printing figure line information on the ply of paper 2, ply of paper 2 materials are brown paper, the inner surface of bag 1 is plastic film layers 4; Be bonded to one through the plastic-coated compacting by binding agent between ply of paper 2 and the base fabric 3, binding agent is the dot matrix arranged distribution, has not only saved binding agent, reduces cost, and paper and plastics compound bag uses back brown paper and base fabric to be easy to tear, and convenient classification is reclaimed again and utilized; The composition surface of ply of paper 2 is uneven, and plastic sheeting is extruded curtain coating and formed plastic membranous layer 4 covering packings on the composition surface of ply of paper; Bag is the gluing pressing in two ends about in the of 1, and bag 1 surface is gone up near the sack position and is provided with self-sealed article 5, and self-sealed article 5 is to be made by raised line and recessed combination, form quick self-styled function, reduce cost, convenient classification is reclaimed again and is utilized, the packaging bag of self-sealing can be used repeatedly.
