Abstract
The utility model discloses high-strength waterproof packing paper. The packing paper is composed of four layers, wherein, the four layers are a lining paper layer, a PE layer, a spinning and sticking layer and the PE layer or a hot melt adhesive layer from top to bottom, and the four layers are integrated after seeping combination and solidification. The utility model id mainly used for packing dessicant, and the utility model has the advantages of favorable moisture permeability, low cost, and high strength in resisting rupture.
Description
The utility model relates to a kind of wrapper, especially a kind of high-strength waterproof wrapper that is used to pack desiccant.
The kind of package paper is a lot, more numerous and diverse, but it is fewer with regard to the wrapper that the technological synthesis performance requriements is higher, just relatively more special as its technical requirements of wrapper that moisture-absorbing desiccant need be used, it should have certain moisture peretrability (absorb moisture content with) that suitable tightness (density suitably makes packed article outside seepage at no time) and breakage resistance (can not burst after the moisture absorption) are accordingly arranged again, so this wrapper technical requirements height, the production difficulty is big, so far domestic still do not have a productive capacity, required high-grade desiccant package paper must be from external import, the productive costs of domestic enterprise is improved greatly, cause a large amount of losses of national foreign exchange simultaneously.
It is good that the purpose of this utility model provides a kind of moisture peretrability, breakage resistance height, the high-strength waterproof wrapper that cost is low.
The technical solution of the utility model is: a kind of high-strength waterproof wrapper, this wrapper are become one after closing curing through oozing by lining paper layer, PE layer, spunbond layer and PE layer or hot melt adhesive layer from the top down successively.
The present complete dependence on import of the employed high-grade desiccant package paper of China enterprise, wherein with regard to japanese product, more than 70,000 yuan per ton, its various performance figure are shown in subordinate list 1.About 40,000 yuan per ton of this high-strength waterproof wrapper is compared with the import wrapper, and it is nearly 50% that cost can reduce, and its various performance figure are shown in subordinate list 2.Subordinate list 1

From subordinate list 1 and subordinate list 2 as can be seen, the various performance figure of this high-strength waterproof wrapper have met or exceeded imported product, use this product to can be country on the one hand and save a large amount of foreign exchanges, and it is long also to have solved the import cycle on the other hand, the problem that cost is high improves economic benefit of enterprises greatly.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is the utility model structural representation.
Structure of the present utility model as shown in Figure 1, form by four-layer structure, be lining paper layer 1 from the top down successively, PE layer 2, spunbond layer 3 and PE layer 4 or hot melt adhesive layer 4, above four-layer structure becomes one after closing curing through oozing, and the effect of lining paper layer 1 is to be convenient to printing, make the outward appearance of product exquisite more, the effect of PE layer 2 and PE layer 4 and hot melt adhesive layer 4 is to be beneficial to wet and bonding.The effect of spunbond layer 3 is to increase the vertical and horizontal tension intensity.
