Abstract
The utility model relates to a paper plastic composite cement bag used for powder or granular materials such as cement, chemical fertilizer, resin, cane sugar, etc. The existing cement bag has poor moisture prevention performance, poor water prevention performance, corrosion prevention performance, and serious breakage. The utility model adopts paper plastic composite materials which is additionally provided with a layer of hot melt plastic film between the kraft paper and the knitting cloth; the kraft paper, the knitting cloth, and the hot melt plastic film can be bonded into the integration after compacted, a plurality of blind holes are high-frequently hit on the surface of the kraft paper, a bonded center joint with the width of 30 to 50 mm is arranged on one side of the knitting cloth, and the kraft paper and the knitting cloth are bonded and compacted with the hot melt plastic. Because of the structure, the utility model is an ideal cement packing bag in sea transportation and long distance transportation, having the advantages of high intensity of the cement bag, good moisture prevention performance, good water prevention performance, and good corrosion prevention performance.
Description
The utility model belongs to the industrial packaging class, relates generally to the packaging bag of powderies such as cement, chemical fertilizer, resin, sucrose and granular material.
At present, the domestic packing that is used for powdery such as cement, chemical fertilizer, sucrose, resin and granular material mainly contains kraft paper bag, gunnysack, common woven bag, reinforcement and reinforces kraft paper bag, nailing kraft paper bag and diablement fort craft paper binder-bag etc.Be used for cement packing, mostly be kraft paper bag, reinforcement reinforcing kraft paper bag and nailing kraft paper bag etc., but it is the multi-layer packaging structure, can not recycle, and consumption is big, waste is serious, and in transportation, be subject to humidity, cracky, not only cause cement loss and waste, but also can cause environmental pollution.Reinforcement is reinforced and the nailing kraft paper bag, and is different with the craft paper shrinkage percentage with the nailing place because of there being reinforcement though its intensity has raising, size instability, also cracky.Gunnysack and common woven bag are because of the restriction (porose) of himself structure, so can not be used for the packing of powder.
The purpose of this utility model provides a kind of simple in structure, light weight, waterproof, protection against the tide, anticorrosion, load-carrying capacity is strong, breakage rate is low, is convenient to long-distance transport, and can be used for powdery and granular material package bag.
Paper compound cement bag of the present utility model, through the bonding centre joint, the seam end, seal and form, its used composite paper-plastic material be by craft paper and woven cloth and between the hot melting plastic film constitute, and the three is integral after the bonding compacting of plastic-coated.
Craft paper is 70～100g/m
2, in the blind hole of its surperficial useful high frequency processing; Woven cloth leaves the wide bonding centre joint of 30～50mm on one side; Its density is 30 * 30～50 * 50/100m
2, it be polypropylene or low pressure polyethylene after wire drawing, circle is knitted the plain cloth that forms; In on one side bonding of woven cloth, sew on, coat hot melting plastic, after the compacting cooling, can make composite paper-plastic material become tubular; When needing, can on composite paper-plastic material, punch.
The utility model compared with prior art has:
1, adopting with plastics is the woven cloth of raw material, simple for production, with low cost.
2, applied widely, not only be used for cement, also can be used for the packing of powderies such as chemical fertilizer, resin, grain, sucrose and granular material.
3, the utility model light weight, but waterproof, protection against the tide, anticorrosion, load-carrying capacity is strong, wear-resisting repeated use repeatedly, save a large amount of craft papeies and other material, remarkable economical and social benefit are arranged.
4, the utility model is particularly suitable for long-distance and seat transport, is the perfect package bag of present cement and other powdery and granular material standard export packages.
Below in conjunction with accompanying drawing the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model composite paper-plastic material;
Fig. 2 is the utility model bag body structure scheme drawing.
Among the figure, woven cloth 1 is to be knitted through wire drawing, circle by polypropylene or polyethylene that to be processed into density be 30 * 30～50 * 50/100cm
2The braiding plain cloth; Plastic film 2 is to extrude 20～50 microns by polypropylene or high pressure polyethylene through extruder, places between woven cloth 1 and the craft paper 3, and the compacting after cooling makes that the three is bonding to be integral.Craft paper 3 needs to handle through the high frequency punching, and some blind holes be arranged in its surface, to help bonding between the three.Composite paper-plastic material after being integral after the compacting, again through printing (when needing punching) with hot melting plastic (polypropylene, high pressure polyethylene, low pressure polyethylene etc.), be applied to all over weave cotton cloth bonding in sew on compacting and the seam end, seal processing, promptly can be made into the packaging bag that needs specification.
In addition, the utility model is during as cement package bags, after making composite paper-plastic material become tubular through the bonding centre joint, make in its upper right corner or bonding size at the oblong valve port cloth of 5 * 15～10 * 30cm scope, and valve port cloth invagination, with the sack edgefold sewing, its effect is to help can cement, and fill automatic sealing behind the cement, prevent to leak.But valve port cloth material composite paper-plastic material also can be a craft paper, or composite plastic woven cloth
The utility model can be according to customer requirement, make woven cloth outside, craft paper is in the lining; Or craft paper outside, woven cloth in the lining two kinds of forms.Can satisfy customer requirements to greatest extent, be suitable for the needs of standard export packages and marine long-distance transport.
