Description
Technical field
The utility model relates to packaging field, is specifically related to a kind of nonwoven fabrics package bag, for packing containing the foods such as meat of juice or the storage transportation of article.
Background technology
Nonwoven be a kind of utilize high polymer section, short fiber or long filament by fiber by machinery or air lay, then hot rolling is reinforced, is arranged finally by crossing the fabric without braiding forming.Nonwoven has gas permeability, but at it at weak effect aspect antiseepage, leakproof, be difficult to use in packaging material.Granted publication number is that the Chinese patent of CN 202200618 U discloses a kind of compound nonwoven cloth, and it is by arranging PE film to improve its water preventing ability, to improve its skin-friendly in nonwoven surface.But its shortcoming is, the heat sealability of this compound nonwoven cloth is poor, heat seal strength is at 7 ~ 8N, peel strength is in 1N, therefore can only be as the packaging material of portable item, as clothes shopping bag etc., cannot be as high weight product as the packing of the above weight of 10kg, and also packaging bag cannot keep stable water preventing ability in load-bearing process.
For this reason, be necessary to develop the non woven cloth composite packaging bag that a kind of bearing is good, heat sealability is good, water preventing ability is stable.
Summary of the invention
The purpose of this utility model is to overcome the defect existing in prior art, and a kind of nonwoven fabrics package bag of high load-bearing is provided.
For achieving the above object, the nonwoven fabrics package bag of high load-bearing of the present utility model, the packaging material of packaging bag comprise by outer nonwoven layer, polyethylene leaching membrane layer, the blowing rete to setting gradually in packaging bag of packaging bag; Polyethylene leaching membrane layer, blowing rete are closely compound, and blowing rete comprises at least one microbedding, and blowing rete a microbedding of inner side be polyethylene heat-sealing microbedding.
Compare with existing non woven cloth composite packaging bag, the nonwoven fabrics package bag of high load-bearing of the present utility model is provided with the blowing rete with heat sealability on polyethylene leaching membrane layer surface, improve heat sealability and the peeling resistance of nonwoven fabrics package bag, thereby improved the weight capacity of non woven cloth composite packaging bag.Blowing rete can be good with nonwoven layer bonding by polyethylene leaching membrane layer, and blown film also has thin thickness, advantage that block-water performance is good, and on polyethylene leaching membrane layer surface, adding blowing rete can obviously not affect the toughness of nonwoven fabrics package bag.This point is very important for the purposes of packaging bag.Such as for packing weight, as meat product, can make packaging bag keep good puncture resistance, improve the service life of packaging bag.
Described PE leaching membrane layer and described nonwoven layer can be closely compound.
In order to improve combined strength bination, preferred technical scheme is to be also compounded with one deck glue layer between described nonwoven layer and described polyethylene leaching membrane layer.Described glue layer is preferably acrylate glue water layer, and the intensity of its bonding nonwoven layer and PE leaching membrane layer is high.
Preferred technical scheme is that described blowing rete is coextrusion blow rete, comprises the polyethylene surface microbedding setting gradually from outside to inside, outer bonding microbedding, intercepts microbedding, interior bonding microbedding, polyethylene heat-sealing microbedding.This coextrusion blow film, except having heat sealability, also has good barrier property, and then can make the purposes of packaging bag further widen.
In order further to improve the heat sealability of material, improve the weight capacity of packaging bag, preferred technical scheme is, described coextrusion blow rete also comprises polyethylene subsurface microbedding and polyethylene time heat-sealing microbedding, polyethylene subsurface microbedding is located between described polyethylene surface microbedding and described outer bonding microbedding, and polyethylene time heat-sealing microbedding is located between described polyethylene heat-sealing microbedding and described interior bonding microbedding.
Wherein, described inside and outside bonding microbedding can be ethylene-vinyl acetate layer, and described obstruct microbedding can be evoh layer.Ethylene-vinyl alcohol copolymer microbedding has the effect of the fragrant resistance of good guarantor oxygen, guarantees the fresh of meat; Ethylene-vinyl acetate microbedding can bond well barrier layer and polyethylene heat-sealing microbedding or polyethylene surface microbedding, improve adhesion strength.
Described nonwoven layer can be polypropylene non-woven fabric layer.Compare as polyester non-woven fabric with other nonwoven, polypropylene non-woven fabric layer has the caking property more good with polyethylene leaching membrane layer.
This packaging bag can be for storage, the transport packaging bag of the large article such as meat of packing.The nonwoven surface of this nonwoven fabrics package bag can play the effect that prevents each packaging bag slippage.In order further to improve the skin-friction force of this nonwoven fabrics package bag, preferred technical scheme is that the outer surface impression of described nonwoven layer has concave convex texture.
Advantage of the present utility model and beneficial effect are: nonwoven fabrics package bag of the present utility model is provided with the blowing rete with polyethylene heat-sealing layer on polyethylene leaching membrane layer surface, improve heat sealability and the peeling resistance of nonwoven fabrics package bag, thereby improved the weight capacity of nonwoven fabrics package bag.This nonwoven fabrics package bag can be more than load-bearing 10kg.This nonwoven fabrics package bag has advantages of high load-bearing, its inner side has good water preventing ability and heat sealability, outer surface has high frictional property, be particularly suitable for the transfer packaging bag containing the storage transportation of liquid article, can prevent that inner package juice from sliding from the transportation packaging bag of oozing out, prevent from storing in a warehouse in packaging bag.In addition,, by optimizing the structure of blown film, also the guarantor's perfume (or spice) for food such as meats packs.
