Abstract

The utility model discloses a high-strength composite bag, mainly relates to the technical field of packaging, and comprises a plastic layer, wherein paper layers are arranged on the inner side and the outer side of the plastic layer, the plastic layer and the paper layer are fixedly bonded through bonding layers, the paper layer comprises a first paper layer and a second paper layer, the first paper layer and the second paper layer are of sawtooth ripple-shaped structures with relatively arranged cross sections, the plastic layer comprises a first plastic layer and a second plastic layer, the first plastic layer and the second plastic layer are of ripple-shaped structures with relatively arranged cross sections, the first paper layer and the second paper layer are of sawtooth ripple-shaped structures with relatively arranged cross sections, a rigid framework is formed, so that the first plastic layer and the second plastic layer are of ripple-shaped structures with relatively arranged cross sections, the ripple-shaped structures greatly enhance the bending strength, can obtain better bearing capacity, and the air filled in the bag formed by sealing through holes plays a certain rigid role, further enhancing the bending strength and obtaining better bearing pressure.

Description

High-strength composite bag

Technical Field

The utility model relates to the technical field of packaging, specifically a high strength composite bag.

Background

The paper-plastic composite bag is formed by compounding plastic and kraft paper, a plastic layer is usually woven by flat filaments with polypropylene and polyethylene as base materials, and the kraft paper is refined composite special kraft paper, so that the paper-plastic composite bag has the characteristics of good waterproofness and attractive appearance, is one of the most popular packaging materials at present, and is environment-friendly, but the overall strength of the paper-plastic composite bag is lower.

SUMMERY OF THE UTILITY MODEL

In view of the deficiencies and drawbacks of the prior art, an object of the present invention is to provide a high strength composite bag.

In order to solve the technical problem, the utility model discloses a following technical scheme: a high strength composite bag characterized in that: including the plastic layer the inside and outside both sides of plastic layer are equipped with the paper layer, plastic layer, paper layer pass through the fixed bonding of bond line, the paper layer includes first ply, second ply, first ply, second ply are the relative sawtooth ripple column structure that sets up in cross-section, the plastic layer moulds the layer including first layer, the second of moulding, first layer, the second of moulding moulds the layer and is the relative wave of setting up in cross-section and roll over the shape structure.

As a further improvement of the utility model, the first paper layer and the second paper layer are connected through a bamboo charcoal adhesive coating.

As a further improvement of the utility model, the first layer of moulding, the second is moulded and is equipped with the through-hole on the ripples of layer is rolled over the fan-head.

Compared with the prior art, the utility model discloses the beneficial effect who has does: the utility model discloses in, first ply, the sawtooth ripple column structure that the second ply set up for the cross-section is relative, form the rigidity skeleton, thereby the effect of reinforceing paper stratum basale structure has been played, first ply, bamboo charcoal adhesive coating between the second ply, play the reinforcement effect on the one hand, on the other hand is in the moisture absorption environmental protection in the use, can prolong the life cycle of contained article, adopt the energy-concerving and environment-protective of recycled paper, first layer of moulding, the second is moulded the ripples shape structure that the layer set up for the cross-section is relative, the bending strength has been strengthened greatly to ripples shape structure, can obtain the bearing capacity of preferred, the through-hole of setting, save material on the one hand, the cost is reduced, certain rigidity effect is played to the inside air that is full of behind the sealed bagging-up of on the other hand through-hole, further reinforcing bending strength, obtain better.

Drawings

The invention will be further described with reference to the accompanying drawings:

fig. 1 is a schematic structural view of a high-strength composite bag of the present invention;

in the figure: 1 plastic layer, 2 paper layers, 3 bonding layers, 4 first paper layers, 5 second paper layers, 6 first plastic layers, 7 second plastic layers, 8 through holes and 9 bamboo charcoal bonding coatings.

Detailed Description

In order to make the technical solution and the advantageous effects of the present invention more clear, the present invention will be further described in detail with reference to the following embodiments.

Fig. 1 is the utility model relates to a structural schematic diagram of high strength composite bag, including plastic layer 1 the inside and outside both sides of plastic layer 1 are equipped with paper layer 2, plastic layer 1, paper layer 2 are through the fixed bonding of bond line 3, paper layer 2 includes first ply 4, second ply 5, first ply 4, second ply 5 pass through bamboo charcoal adhesive coating 9 and connect, first ply 4, second ply 5 are the relative sawtooth ripple column structure that sets up in cross-section, layer 7 is moulded to plastic layer 1 including first layer 6, the second of moulding, layer 6, the second is moulded to first mould the wave of layer 7 for the relative setting in cross-section and is folded the column structure first layer 6, the second of moulding are moulded the wave of layer 7 and are equipped with through-hole 8 on the wind head.

The first paper layer 4 and the second paper layer 5 are of sawtooth corrugated structures with opposite cross sections to form a rigid framework, so that the function of strengthening the structure of the paper layer 2 is achieved, the bamboo charcoal adhesive coating 9 between the first paper layer 4 and the second paper layer 5 plays a strengthening role on one hand, moisture absorption and environmental protection are achieved in the using process on the other hand, the service cycle of contained objects can be prolonged, the regenerated paper is energy-saving and environment-friendly, the first plastic layer 6 and the second plastic layer 7 are of corrugated structures with opposite cross sections, the bending strength is greatly enhanced through the corrugated structures, better bearing pressure can be obtained, the arranged through holes 8 save materials and reduce cost on the one hand, and the air filled inside the through holes 8 after being sealed into bags plays a certain rigid role on the other hand, the bending strength is further enhanced, and better bearing pressure is obtained.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements.
