Abstract
The utility model discloses a paper bag, which mainly comprises a paper bag main body and a carrying handle, wherein the carrying handle is arranged at the opening of the paper bag main body, and thepaper bag main body is of a five-layer paper-plastic composite structure, i.e., an aluminum membrane layer, a first polyethylene layer, a reinforcing fiber layer, a second polyethylene layer and a paper layer from inside to outside; and a sealing strip is arranged on the paper bag main body at a distance of 0.8 cm to 15cm below the opening. The carrying handle is of an integrated string, is embedded between the first polyethylene layer and the reinforcing fiber layer of the paper bag main body, and extends to the bottom from one side of the opening of the paper bag and then extends out of theother side of the opening of the paper bag through the bottom. The carrying handle can also be embedded between the second polyethylene layer and the reinforcing fiber layer of the paper bag main body, and the fibers of the reinforcing fiber layer are interwoven in a grid way.
Description
One, technical field
The utility model relates to a kind of sack, particularly a kind of paper bag.
Two, background technology
The kind of paper bag descriptions of materials a lot, paper are various at present, style is also a lot.Paper bag generally adopts art post paperboard, white board, art paper, craft paper is made, and is the speciality paper manufacturing on a small quantity in addition, according to the bag limit, bottom and back cover mode difference have bag at the bottom of bag at the bottom of the open seam, the bonding angle of opening, valve formula to sew up at the bottom of bag, the flat hex end of valve formula four kinds of paper bag patterns such as binder-bag.Because opening style factor, so this name of Paper handbag occurred, some paper bag has handle. use craft paper bag more than four layers, products such as packing cement, chemical fertilizer.According to the performance of packed article, adopt different paper bag patterns.
There is insufficient strength in simple paper bag, and is non-watertight, and leak tightness is poor, the shortcoming that can not well be incubated.The simple paper bag intensity of the intensity ratio of paper and plastics compound bag will be got well, but general paper and plastics compound bag does not have heat preservation effect yet.And has the manufacturing process more complicated of the paper and plastics compound bag of heat insulation effect.
Three, summary of the invention
The purpose of this utility model is: overcome existing paper bag insufficient strength, non-watertight, leak tightness is poor, and the shortcoming that can not well be incubated provides a kind of paper bag, has reasonable intensity, waterproof, good seal and can be incubated.
Technical scheme of the present utility model is as follows: a kind of paper bag, mainly form by paper bag main body and handle, the opening part of paper bag main body is provided with handle, the paper bag main body is five layers of paper composite structure, be aluminum membranous layer, first polyethylene layer, fortifying fibre layer, second polyethylene layer, ply of paper from inside to outside, 0.8～15cm place is provided with sealing band below the opening part of paper bag main body.Described handle is a complete rope, and handle is embedded between first polyethylene layer and fortifying fibre layer of paper bag main body, one side by the paper bag opening extend to the bottom, come out by the another side of paper bag opening through the bottom again.Described handle also can be embedded between second polyethylene layer and fortifying fibre layer of paper bag main body.The fortifying fibre layer, fiber is with the grid type weaving.
Beneficial effect:
1. the paper bag main body is five layers of composite structure, and fortifying fibre layer has wherein improved the intensity of paper bag greatly, and aluminum membranous layer can waterproof, cooperates the sealing band of opening part can reach the purpose of insulation.
2. and the two layers of polyethylene layer also can play certain waterproof and strengthen the effect of intensity.
3. and handle adopts whole-root rope, extend to the paper bag opening part, can better strengthen intensity like this, improve bearing capacity via the bottom.
Four, description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the scheme drawing of fortifying fibre layer of the present utility model.
Five, the specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described further:
As Fig. 1,2, a kind of paper bag, mainly form by paper bag main body 1 and handle 2, the opening part of paper bag main body 1 is provided with handle 2, paper bag main body 1 is five layers of paper composite structure, be aluminum membranous layer, first polyethylene layer, fortifying fibre layer, second polyethylene layer, ply of paper from inside to outside, 0.8～15cm place is provided with sealing band 3 below the opening part of paper bag main body 1.So just can well reach insulation, leak free effect.
Described paper bag, described handle 2 is a complete rope, handle 2 is embedded between first polyethylene layer and fortifying fibre layer of paper bag main body 1, one side by the paper bag opening extend to the bottom, come out by the another side of paper bag opening through the bottom again.Described paper bag, described handle 2 are embedded between second polyethylene layer and fortifying fibre layer of paper bag main body 1.Described paper bag, the fortifying fibre layer, fiber is with the grid type weaving.This structure can actv. waterproof and enhancing intensity.
