Abstract

The utility model relates to high-strength dead tissue green paper for a package bag. The utility model is composed of two layers of paper, a layer of mesh ribs and a layer of radial ribs, wherein the layer of mesh ribs and the layer of radial ribs are attached to each other so as to form a double-layer composite net reinforcing rib which is clamped between the two layers of paper. The interiors of meshes which are formed by the double-layer composite net of reinforcing rib are provided with simple-layer paper; a double-layer reinforcing rib which is formed by compounding by layer of mesh ribs and the layer of radial ribs is clamped between the two layers of paper, wherein the mesh ribs can enhance the strength of the package bag paper with the reinforcing rib; the radial ribs can enhance the longitudinal strength of the package bag paper with the reinforcing rib so as to enable the package bag to bear heavier goods. The utility model has the advantages of enhanced integral strength, good ventilation property, low cost and no environment pollution.

Description

High strength is buried yarn green package bag paper

The utility model relates to a kind of packing bag paper, refers to a kind of intensity height especially, good permeability, and high strength free from environmental pollution is buried yarn green package bag paper.

In the past, be used to pack the packaging bag of cement, grain, beverage, agricultural chemicals, chemical industry powder, salt, alkali, sugar, tea etc., use the paper bag of which floor suit mostly, and paper bag breaks easily, thereby causes a large amount of wastes, for example, according to the statistics made by the departments concerned, China is 4.5% because of the cement package bags bale broken causes the cement scatter ratio, scatter and disappear ratio every year, and every year is lost 60,000 tons of cement in preresearch estimates at least, is worth more than 800,000,000 yuan of Renminbi; Perhaps use cloth bag or the gunnysack made by cotton, fiber crops, natural fiber, also have and use paper and textile bags fit to pack.Because these packaging bags all are disposable, be difficult to recycling, so its cost is higher.In today of chemical frbre industry high development, a big chunk in the above-mentioned packaging bag is substituted by the polypropylene woven bag of plastic bag, polypropylene woven bag or composite plastic film and fibrous glass bag, thereby has solved the strength problem of packaging bag preferably.But, extremely stable because the use amount of packaging bag is very big with the poly-mer class packaging bag chemical nature that the chemical industry method is produced, also imputrescibility of several years, more than ten years even longer time in natural environment; Today, these packaging wastes have become the rubbish of contaminated environment, destroy the pernicious gas that then produces atmosphere pollution by fire, abandon and are harmful to soil layer construction in the farmland again.In recent years, though developed the poly-mer that can degrade voluntarily at occurring in nature, its industrialized producing technology is not attained full maturity as yet, and its productive costs is also high, especially it is to be noted: modern medicine proves, many plastic products in the production process and the course of processing, can produce or sneak into the deletrious material of health, and high-polymer membrane permeability to air extreme difference, be unfavorable for food fresh keeping, so in many instances, these poly-mer goods should not be used for packaging for foodstuff.

From health and environmental protection, develop a kind of intensity height, can be moistureproof and have good permeability to air, can recycling, can decompose and green package bag free from environmental pollution voluntarily at realm of nature again, become the task of top priority.

The purpose of this utility model provides a kind of intensity height, good permeability, and cost is low, can recycling, can decompose voluntarily and high strength free from environmental pollution is buried yarn green package bag paper at realm of nature again.

For achieving the above object, the utility model is taked following technical scheme:

A kind of high strength is buried yarn green package bag paper, form by two layers of paper, the netted muscle of one deck, one deck warp-wise muscle, the netted muscle of described one deck, the applying of one deck warp-wise muscle form two-layer compound net reinforced rib and are folded up between two layers of paper, and the mesh that described two-layer compound net reinforced rib forms is interior to be single-part stationery.

Clamp the double-deck reinforced rib that is composited by one deck net dress muscle and one deck warp-wise muscle in the utility model two layers of paper, wherein netted muscle can make the intensity of folder muscle packing bag paper improve, the warp-wise muscle then can make its intensity raising longitudinally, thereby can make packaging bag can bear heavier weight, thereby, bulk strength of the present utility model is improved greatly by the double-deck reinforced rib that netted muscle and warp-wise muscle are composited.

The utility model clamps two-layer compound net reinforced rib owing to adopt once moulding method in two-layer paper pulp, need not use adhesives, use the bad disadvantage of permeability to air that adhesives brought thereby solved, again can saving in material, simplify Fabrication procedure, productive costs is reduced.Particularly the utility model is recyclable utilizes again, can decompose voluntarily and free from environmental pollution at occurring in nature again, becomes green package bag paper worthy of the name.

The utility model embodiment is described with reference to the accompanying drawings as follows:

Fig. 1 is the utility model embodiment scheme drawing (part).

Fig. 2 analyses and observe enlarged diagram for A-A shown in Figure 1 position.

One deck diamond-mesh muscle scheme drawing of Fig. 3 for being adopted among the utility model embodiment.

One deck warp-wise muscle scheme drawing of Fig. 4 for being adopted among the utility model embodiment.

The figure number explanation:

1, be positioned at netted muscle and warp-wise muscle joint place, be coated on one deck paper on the warp-wise muscle,

2, be positioned at netted muscle and warp-wise muscle joint place, be coated on one deck paper on the netted muscle,

3, warp-wise muscle,

4, be positioned at the single-part stationery of the mesh of two-layer compound net reinforced rib formation,

5, netted muscle.

Use the raw material of true qualities wood pulp paper as packing bag paper, specification is 140 gram/m ², one deck diamond-mesh muscle is that the cotton thread with 10 yarns is made into, and the every length of side of prism mesh is 12mm, and one deck warp-wise muscle also adopts the cotton thread of 10 yarns to arrange along warp-wise and forms, and every two adjacent warp-wise muscle are at a distance of 10mm.

Adopt the special-shaped net forming machine of mixing that the netted muscle of one deck is fitted into two-layer compound net reinforced rib with one deck warp-wise muscle, adopt then bury the yarn braider with two-layer liquid paper pulp when the moulding not, above-mentioned two-layer compound net reinforced rib is imbedded therebetween continuously, buried yarn green package bag paper thereby constituted high strength.

The line muscle that can adopt cotton thread muscle, linen thread muscle and other natural fiber material to make.
