Abstract
The invention discloses a composite buffer sheet which is composed of three elastic buffer layers, wherein the middle elastic buffer layer is composed of a low-density polyethylene foam board, and the other two elastic buffer layers are respectively composed of a high-density polyethylene foam board and respectively adhered to the upside and downside of the middle elastic buffer layer. The density of the middle elastic buffer layer is less than the densities of the other two elastic buffer layers. The composite buffer sheet disclosed by the invention has the advantages that through compositing the low-density and high-density materials, the buffering property, creep property, bearing capacity and puncture resistance of the composite buffer sheet are greatly enhanced; based on the enhancement of the properties, during the packing of products, less materials and smaller package size can be used so as to meet the requirements for product protection; because the package size is decreased, the volume of a packing case is correspondingly decreased, thereby greatly reducing the costs for storage and transportation; and because the application amount of materials is reduced, the resource degradation and the pollution to the environment are reduced, thereby reducing the overall packaging cost.
Description
Technical field:
The present invention relates to packing technique, relate in particular to the packing material that polyethylene (EPE) buffering expanded material constitutes, particularly a kind of composite buffering sheet material.
Background technology:
In the prior art, the multi-layer sheet that polyethylene (EPE) buffering foamed material extensively adopts the polyethylene coiled material by density of the same race to be bonded.In packaging process; its shock-absorbing capacity, croop property, bearing capacity, anti-pierce force etc. are more weak; for protecting product; then need to use a large amount of polyethylene foam materials; simultaneously the package volume increases, and causes the increase of cost, storage and cost of transportation of external packing (as: carton) and the generation of packing waste material in a large number.
Summary of the invention:
The object of the present invention is to provide a kind of composite buffering sheet material, more weak technical problem such as the bonding multi-layer sheet shock-absorbing capacity of the polyethylene coiled material that described this composite buffering sheet material will solve density of the same race in the prior art, croop property, bearing capacity, anti-pierce force.
This composite buffering sheet material of the present invention constitutes by three elastic buffer plies are bonding, being positioned at its middle middle elastic cord breaker is made of a low density polyethylene (LDPE) cystosepiment, wherein, remaining two elastic cord breaker is made of the high density polyethylene (HDPE) cystosepiment respectively, and is bonded in the upside and the downside of described middle elastic cord breaker respectively.
Further, the thickness of described middle elastic cord breaker is greater than the thickness of all the other two elastic cord breakers.
Further, the thickness of all the other two elastic cord breakers equates.
Further, in the middle of described the density of elastic cord breaker less than all the other two elastic cord breakers density.
Further, described in the middle of the coefficient of elasticity of elastic cord breaker less than the coefficient of elasticity of all the other two elastic cord breakers, the case hardness of all the other two elastic cord breakers and mechanical strength are respectively greater than the case hardness and the mechanical strength of middle elastic cord breaker.
Concrete, the high density polyethylene (HDPE) foam of the low density polyethylene (LDPE) foam of elastic cord breaker and all the other two elastic cord breakers of formation obtains through foaming extrusion molding by the low density polyethylene (LDPE) particle in the middle of constituting.
The present invention is bonded by the polyethylene coiled material multilayer of high and low density.The intermediate layer is the low density polyethylene (LDPE) foam, outmost two-layer material is the high density polyethylene (HDPE) foam, high and low density material bonding, the coefficient of elasticity of material is increased, unit volume absorbs impact energy and increases, the shock-absorbing capacity of material strengthens, thereby satisfies the required material of same buffering effect and reduce.Because the superficial layer of material is a high density material, the anti-pierce force of material strengthens.According to ASTM D3575 suffix BB standard, composite buffering sheet material of the present invention can be by 1000 hours creep test.
The present invention compared with prior art, its effect is actively and significantly.The present invention is compound by the material of high and low density, has strengthened shock-absorbing capacity, croop property, bearing capacity, the anti-pierce force of material widely.Based on the enhancing of these performances, in the packing of product, can use material still less, littler Package size reaches the requirement of protection product.Package size reduces, and then the package volume is corresponding reduces, and this greatly reduces the expense of storage and transportation; The minimizing of material usage has reduced the consumption of resource and the pollution of environment, thereby the overall cost of packing is reduced.
Description of drawings:
Fig. 1 is the structural representation of composite buffering sheet material of the present invention.
The specific embodiment:
As shown in Figure 1, composite buffering sheet material of the present invention, constitute by three elastic cord breakers, being positioned at its middle middle elastic cord breaker 2 is made of a low density polyethylene (LDPE) cystosepiment, wherein, remaining elastic cord breaker 1 and elastic cord breaker 3 are made of the high density polyethylene (HDPE) cystosepiment respectively, and are bonded in the upside and the downside of described middle elastic cord breaker 2 respectively.
Further, the thickness of described elastic cord breaker 2 is greater than the thickness of elastic cord breaker 1 and elastic cord breaker 3.
Further, the thickness of described elastic cord breaker 1 and elastic cord breaker 3 equates.
Further, the density of described middle elastic cord breaker 2 is less than the density of elastic cord breaker 1 and elastic cord breaker 3.
Further, the coefficient of elasticity of elastic cord breaker 2 is less than the coefficient of elasticity of elastic cord breaker 1 and elastic cord breaker 3 in the middle of described, and the case hardness of elastic cord breaker 1 and elastic cord breaker 3 and mechanical strength are respectively greater than the case hardness and the mechanical strength of middle elastic cord breaker 2.
Concrete, the high density polyethylene (HDPE) foam of the low density polyethylene (LDPE) foam of elastic cord breaker 2 and formation elastic cord breaker 1 and elastic cord breaker 3 obtains through foaming extrusion molding by the low density polyethylene (LDPE) particle in the middle of constituting.
In a preferred embodiment of the present invention, the intermediate layer is the low density polyethylene (LDPE) foam, the two-layer of upper and lower sides is the high density polyethylene (HDPE) foam, high and low density material bonding, the coefficient of elasticity of material is increased, unit volume absorbs impact energy and increases, and the shock-absorbing capacity of material strengthens, thereby satisfies the required material of same buffering effect and reduce.Because the superficial layer of material is a high density material, the anti-pierce force of material strengthens.According to ASTM D3575 suffix BB standard, composite buffering sheet material of the present invention can be by 1000 hours creep test.
