Description

A kind of Packaging buffering material

Technical field

The utility model relates to a kind of Packaging buffering material, particularly utilize low density polyethylene (LDPE) foaming material to form first cushion layer of a low range foaming structure respectively, and second cushion layer of a high magnification foaming structure, after its adjacency is mutually combined, have best buffering and shock-absorbing effect, and reduce material consumption, transport space, cost-cutting, and be easy to reclaim classification and resolution process.

Background technology

At present general common liquid crystal screen display or other breakables etc. all need be done shockproof processing during its packing, thus need utilize some Packaging buffering materials, thus cushion during as carrying, the protective of shock-absorbing.And the current packaging fender, invention that TaiWan, China on November 21st, 2009 the announced I317343 number patent case about the packing box that is used to transport glass substrate is for example arranged, it discloses a box body, it comprises: an outer fender and an internal layer fender, this skin fender is positioned at the outside of this internal layer fender, this internal layer fender surrounds a receiving space, the expansion ratio of this internal layer fender is greater than the expansion ratio of this skin fender, and this internal layer fender is doped with preventing property of static material, and this skin fender and this internal layer fender adopt high density polyethylene (HDPE), polypropylene, in low density polyethylene (LDPE) and the ethane-acetic acid ethyenyl ester co-polymer any one is made; Because it makes the shape of a box body,, and can't be fit to various difform article packings uses, so quite undesirable in the use so caused its packaging volume excessive and transport difficultly.

For this reason, M367809 number patent case of utility model of on November 1st, 2009 being announced just like TaiWan, China then about the environmental protection package plate body structure of tool physical blowing plastic material, it discloses: plastics; And gaseous state gas, it is gaseous state gas or pure gaseous state unreactable gas, and this gaseous state gas mixes the wrapping plate body structure that forms tool foamed plastic material with plastics; And the wrapping plate body structure tool skin and the internal layer of this tool foamed plastic material, and this internal layer is coated by skin, and skin is that plastic overmold is counted bubble for the plastics internal layer, these plastics can be the plastic PU of TPU heat, LDPE low density polyethylene (LDPE), PP polypropylene, and the foaming ratio of foamed plastic material is 800% to 2000% of plastics for gaseous state gas; Like this, its manufacturing course is quite complicated, and manufacturing cost is higher.

M365339 number patent case of utility model of on September 21st, 2009 being announced in addition again about the Packaging buffering material just like TaiWan, China, it includes: two outer layer bodies are made by high density foaming material; And interlayer body, be made, and insert and put and be bonding between these outer layer bodies that respectively this outer layer body is that high density polyethylene (HDPE) foaming material is made by low-density foamed material, this interlayer body is then made for low density polyethylene (LDPE) foaming material, and this outer layer body is that density is 0.950 to 0.965g/cm again ³The foaming material of (g/cubic centimeter) is 0.915 to 0.930g/cm and this interlayer body is a density ³The foaming material.

Above-mentioned prior art is mainly utilized the combination of high density polyethylene (HDPE) foaming material and low density polyethylene (LDPE) foaming material, with use as fender, but, because it utilizes the polyethylene foam material combination of two kinds of high and low density of difference, therefore after using, handle and quite be difficult to when reclaiming decompose and classification, cause in the recycling because of difficulty, and have influence on environmental demands, and because its weight of high density polyethylene (HDPE) foaming material is heavier, volume is bigger, take up room in the time of also can causing transportation and difficult carrying, so also there is its shortcoming to exist in the use.

The utility model content

The purpose of this utility model is to provide a kind of Packaging buffering material, and padded coaming manufacturing cost height in the prior art, volume are big to solve, Heavy Weight and the problem that is difficult for classification and decomposes in the environmental protection recycling.

In order to reach above-mentioned purpose, solution of the present utility model is:

A kind of Packaging buffering material wherein, comprising:

At least one first cushion layer, it is a low density polyethylene layer, and have the foaming density between 0.115 to 0.077g/cm ³Between the low range foaming structure;

At least one second cushion layer, itself and this first cushion layer in abutting connection with and mutually combine, and this second cushion layer is low density polyethylene layer, and have foaming density between 0.037 to 0.022g/cm ³Between the high magnification foaming structure.

Further, this first cushion layer is made as one, and this second cushion layer also is made as one.

Further, this first cushion layer is made as two, and this second cushion layer then is made as one, and this second cushion layer is located between this 2 first cushion layer again.

Further, this first cushion layer is made as more than two, and this second cushion layer then is made as more than two.

Further, each first cushion layer is irregular arrangement with each second cushion layer and combines.

After adopting said structure, the utlity model has following advantage:

One, the utility model utilizes low density polyethylene (LDPE) foaming material, form first cushion layer of low range foaming structure respectively, and second cushion layer that forms the high magnification foaming structure, because it is with made with a kind of material, therefore reclaiming on classification and the resolution process, simple quite easily, thus environmental protection requirement can be conformed with fully, and can reach hundred-percent recycling rate.

Two, the utility model is with the low density polyethylene (LDPE) material that foams, and does combination mutually after forming low range foaming structure and high magnification foaming structure respectively, so the optimized buffer and the shock-absorbing effect of breakables such as liquid crystal screen display can be provided.

Three, the utility model can reduce the use amount of packing, and reduces space shared when transporting, and can significantly reduce shipment and delivery cost.

Four, the utility model can be according to Different Package article characteristic, and selects first cushion layer of the different numbers of plies and second cushion layer to do in conjunction with changing, thereby increases different bearing capacities and vibration strength, the yield when transporting to improve article packing.
