Abstract
The composite tubular seam-less packing bag includes a seam-less tubular inner paper layer 1, a seam-less tubular netted cloth layer 2 with homogeneously distributed warps and end-less ring wefts; a seam-less tubular paper layer 3, a seam-less tubular netted cloth layer 4 with right and left encircled wefts and a seam-less tubular paper layer 5 successively from inside to outside. The layer 1 has one anti-stick heat resisting layer or anticorrosive layer painted in the inner surface; both the layer 2 and the layer 4 have heat resisting isolating film adhered to its inner and outer surfaces; and all the five layers are hot pressed into one integral composite seam-less packing tube. The packing bag has folding walls on two sides, sewing line in the bottom and pasted bottom beside the sewing line. The packing bag is pressure resistant, heat resistant, leak-less and anticorrosive.
Description
Invention field
The present invention relates to a kind of packaging bag, the packaging bag of particularly a kind of five layers of common compound type cartridge type middle seam free.
Background technology
Normally used packaging bag has paper yarn complex pocket, paper and plastics compound bag on the market now, is two layers or three layers of complex pocket.These existing two layers or three-layer composite packaging bags are difficult to solve the specific (special) requirements that present heavy wrapping field and extra package field need packaging bag to have high pressure resistant, high temperature resistant, antiseep, withstanding corrosion or prevent that hard thing from puncturing etc.
Chinese patent 95222720.7 discloses the middle paper twine combined package bag that accompanies one deck geographic mesh of a kind of two layers of paper; Chinese patent 97239992.5 has been introduced the three-layer composite packaging bag of a kind of polyvinyl water soluble yarn and paper.A large amount of uses then is the kraft compounded paper plastic combined package bag that forms of one deck plastic knit-weaving fabric and one deck on the market.
Two layers of said structure or the defective of three-layer composite packaging bag (three-layer composite packaging bag, the paper plastic combined package bag of paper twine combined package bag, polyvinyl water soluble yarn and paper) are: can not satisfy the requirement to packaging bag of heavy wrapping field and extra package field, the intensity of this packaging bag, thickness, firmness are subjected to forming the materials limitations of packaging bag, if solve problems such as its intensity, firmness by strengthening material thickness merely, composite bed can take place again separate, phenomenons such as bonding insecure or material jackknifing.
Summary of the invention
The objective of the invention is to overcome that existing packaging bag exists is difficult to satisfy the defective that the required packaging bag in present heavy wrapping field and extra package field has high pressure resistant, high temperature resistant, antiseep, withstanding corrosion or prevents specific (special) requirements such as hard thing punctures, and provide a kind of applicable to high pressure resistant, high temperature resistant, antiseep, withstanding corrosion or prevent that sandwiching two layers in the middle of the three-ply paper of specific (special) requirements such as hard thing punctures strengthens five layers of common compound type cartridge type middle seam free packaging bags that grid cloth are formed.
Technical scheme of the present invention is as follows:
Five layers of common compound type cartridge type middle seam free provided by the invention packaging bag, it is characterized in that, the cartridge type inner paper layer 1 that comprises middle seam free from inside to outside successively, warp is uniform and the cartridge type scrim layer 2 of parallel endless loop around the middle seam free that constitutes arranged, the cartridge type ply of paper 3 of middle seam free, revolve about parallel around middle seam free cartridge type grid layer of cloth 4 and the cartridge type ply of paper 5 of middle seam free; Apply antiseized heat-resistant layer of one deck or anticorrosion coating on described cartridge type inner paper layer 1 inside face; Respectively be covered with one deck heatproof on the surfaces externally and internally of described cartridge type scrim layer 2 and isolate bonding film; Respectively be covered with one deck heatproof on the surfaces externally and internally of described cartridge type grid layer of cloth 4 and isolate bonding film; Described cartridge type inner paper layer 1, cartridge type scrim layer 2, cartridge type ply of paper 3, cartridge type grid layer of cloth 4 and cartridge type ply of paper 5 are hot pressed into integrally formed five layers of common compound type middle seam free packing tube; This middle seam free packing tube dual-side is provided with band and has folded wall, and this middle seam free packing tube base is provided with sews up all-in-one-piece lignilite 6 with its base; Also can stick with paste at the end 7 outside the lignilite 6.
Five layers of common compound type cartridge type middle seam free provided by the invention packaging bag, high pressure resistant, high temperature resistant, antiseep, the withstanding corrosion that can solve that present heavy wrapping field and extra package field need that packaging bag has or prevent specific (special) requirements such as hard thing punctures, the packaging bag that alternative screen cloth papermaking material is formed, packing containers such as alternative work durm, plastic barrel, paper web; Can be used for packing special articles such as withstand voltage, heatproof, antiseep, withstanding corrosion.

Embodiment
Further describe the present invention below in conjunction with drawings and Examples:
By Fig. 1 and Fig. 2 as can be known, five layers of common compound type cartridge type middle seam free of the present invention packaging bag, it is characterized in that, the cartridge type inner paper layer 1 that comprises middle seam free from inside to outside successively, warp is uniform and the cartridge type scrim layer 2 of parallel endless loop around the middle seam free that constitutes arranged, the cartridge type ply of paper 3 of middle seam free, revolve about parallel around middle seam free cartridge type grid layer of cloth 4 and the cartridge type ply of paper 5 of middle seam free; Apply antiseized heat-resistant layer of one deck or anticorrosion coating on described cartridge type inner paper layer 1 inside face; Respectively be covered with one deck heatproof on the surfaces externally and internally of described cartridge type scrim layer 2 and isolate bonding film; Respectively be covered with one deck heatproof on the surfaces externally and internally of described cartridge type grid layer of cloth 4 and isolate bonding film; Described cartridge type inner paper layer 1, cartridge type scrim layer 2, cartridge type ply of paper 3, cartridge type grid layer of cloth 4 and cartridge type ply of paper 5 are hot pressed into integrally formed five layers of common compound type middle seam free packing tube; This middle seam free packing tube dual-side is provided with band and has folded wall, and 8 among Fig. 1 folded the broken line of wall for this, and this middle seam free packing tube base is provided with sews up all-in-one-piece lignilite 6 with its base; Also can stick with paste at the end 7 outside the lignilite 6.
Fig. 2 is the A-A cutaway view of Fig. 1, can be clear that from Fig. 2, five layers of common compound type cartridge type middle seam free packaging bag middle seam free structure of the present invention, compare with the packaging bag that is rolled into tube after the traditional Planar Compound again, have high pressure resistantly significantly, isolate antiseepage, not advantage such as cracky.
