Abstract
The utility model discloses an anti-seepage paper-plastic composite woven bag and is aimed at providing the anti-seepage paper-plastic composite woven bag which is advantaged by being low in cost, small in occupied space of production equipment, low in a requirement for working environment and simple in operation. The anti-seepage paper-plastic composite woven bag comprises a woven bag body with upper and lower ends opened. The anti-seepage paper-plastic composite woven bag is characterized in that firstly, a paper-plastic cloth strip is stitched near the edge outside an opening at the lower end of the woven bag body by a sewing thread; secondly, the lower end of the woven bag body after being sealed is coated by a hot-melting adhesive tape in a folding state; and finally, the lower end of the woven bag body, after being coated by the hot-melting adhesive tape, is coated by a plastic adhesive tape in a folding state. The anti-seepage paper-plastic composite woven bag has following beneficial effects: power is less susceptible to seeping out of a gap at a stitching position of the sewing thread by adoption of the structure of the paper-plastic cloth strip stitched by the sewing thread; the hot-melting adhesive tape is used for sealing the gap at the stitching position of the sewing thread; and by virtue of the additionally-arranged paper-plastic cloth strip, the problem that the paper-plastic composite woven bag is damaged to seep materials at the corner at the bottom edge when being unloaded from a vehicle at a high position during transport is resolved.
Description
Technical field
The utility model relates to a kind of Polywoven Bag, particularly a kind of antiseep paper compound braided bag.
Background technology
At present, paper composite plastic woven bag is that a kind of being widely used in packed various as sugar, cement, and the packaging bag of the article such as fertilizer, chemicals and PVC powder, normally consists of craft paper top layer and plastic woven cloth inside liner.Wherein plastic woven cloth is that to take polypropylene or polyethylene be primary raw material, with draw bench, produces flat filament, by circular weaving machine, flat filament braiding is made.Paper composite plastic woven bag production process is to utilize polypropylene dedicated, the polyethylene membrane coating material of melting by plastic woven cloth together with kraft compounded, and this process is film.Half-blank after film is by printing and bag making unit, make the cylinder bag of center joint bonding, be the paper composite plastic woven bag body of upper and lower end opening, finally bag lower end is adopted to fuse machine Hot melt adhesive tape melt process, or the method for the sealed paper that sticks with glue seals bag lower edge, after sealing, with sewing machine, bag lower end packing cloth or hot melt adhesive plaster are sewed up by the rope made of hemp and sewing thread again.But nine moulding mixtures while utilizing paper composite plastic woven bag that said method is made to pack various dusty raw materials as PVC eight moulding mixtures, PVC, these powder can spill or drain to paper composite plastic woven bag bottom from the gap of the paper composite plastic woven bag lower end rope made of hemp and sewing thread suture, and finally two angles by bottom drain to outside.When the paper composite plastic woven bag of filling powdery product is unloaded by eminence in transportation, paper composite plastic woven bag is the damaged material that leaks from band angle, base easily simultaneously, and the damaged material that leaks reaches 10% according to statistics.For addressing these problems, Chinese patent notification number CN1923502A, the day for announcing is on March 7th, 2007, denomination of invention discloses for " composite plastic woven bag for fine powder product " a kind of composite plastic woven bag addressing these problems, the bottom margin of this composite plastic woven bag for fine powder product utilizes super sonic processing and is formed with paste section, the top of paste section is sewed up with sewing thread, sealed paper be utilize the hot-melt object after fusing coat aqueous adhesive or latex after be wrapped in the outside of paste section and sewing thread.But this composite plastic woven bag adopts super sonic to process aborning, needs special-purpose ultrasonic equipment, and equipment need take certain space, and operator quality is had relatively high expectations, and working environment requires high, and cost is higher.
Summary of the invention
In view of the problem that known technology exists, the utility model object is to provide a kind of paper plastic bag that prevents the outside seepage of fine powder.This paper plastic bag cost is lower, and production facilities takes up room little, and working environment requires low, simple to operate.
The technical scheme that the utility model technical solution problem adopts is, the woven bag bodies that comprises upper and lower end opening, it is characterized in that: first paper cloth is sewn on near side (ns) place outside the lower ending opening of woven bag bodies by sewing thread and seals, by Hot melt adhesive tape, with rugosity, be coated on the woven bag bodies lower end after sealing again, finally with plastic colloidal cloth, with rugosity, be coated on through the coated woven bag bodies lower end of Hot melt adhesive tape.
The paper cloth of above-mentioned antiseep paper compound braided bag is the leftover pieces in film operation before making woven bag bodies.
The hot melt adhesive plaster of above-mentioned antiseep paper compound braided bag is to be heated hot melt adhesive is melted and produces viscosity by electric hot plate, and hot melt adhesive plaster is covered the plastics paper cloth sewing by sewing thread completely.
The coated woven bag bodies of the coated relative hot melt adhesive plaster of plastic colloidal cloth of above-mentioned antiseep paper compound braided bag is more shallow.
The paper cloth of above-mentioned antiseep paper compound braided bag, hot melt adhesive plaster, the coated place of plastic colloidal cloth is all wider than woven bag bodies.
Compared with prior art, the utility model has adopted 3 layers of hermetically-sealed construction, the paper cloth that sewing thread is sewed up, Hot melt adhesive tape, plastic colloidal cloth.The structure of the paper cloth that sewing thread is sewed up makes powder be difficult for spilling from the gap of sewing thread suture, and hot melt adhesive plaster is again by the gap sealing of sewing thread suture.Plastics paper cloth and plastic colloidal cloth have increased the bottom edge sealing intensity of woven bag simultaneously, particularly increased paper cloth, making to do product falls while wrapping experiment, 2.4 meters of the bags that fall by national standard are increased to 4 meters, place, band angle, base is the damaged material that leaks not yet, thereby solved while being unloaded by eminence in transportation, paper composite plastic woven bag can be from band angle, base damaged problem of leaking material.Secondly, do not need special-purpose ultrasonic equipment, equipment occupation space is little, less demanding to operating personal, working environment requires low, simple to operate, cost is lower, is the leftover pieces in film operation before making woven bag bodies at paper cloth simultaneously, is the recycling of the refuse of product.
