Abstract
The utility model relates to a soft edge packing bag for composite cement. In the compound process of outer layer paper, inner layer paper and meshed composite material, certain length of the edge does not adhere; consequently, the edged bag breakage phenomenon of the hard-edge composite cement packaging bags is reduced, the breakage rate is reduced, and the bag breakage problem, in the cement packaging field of manufacture of building materials, which is under resolution for long period is solved.
Description
The utility model relates to the building material cement packaging field.
At present, the packaging bag of hard-edge complex cement is to take traditional complex form to be composited, and has the netty compound material of certain tensile strength by two-layer cement packing paper therebetween last layer, forms by cylinder gluing compacting.Because ectonexine and netty compound material are all bonding, cause breakage of packages rate height.
The purpose of this utility model is by changing the adhesion area of compound paper bag, making traditional complex cement packaging bag become the complex cement packaging bag of soft limit, thereby reduced the breakage of packages rate.
In order to realize above-mentioned task, the technical solution of the utility model is: allow the edge part not bonding in recombination process, increase edge movable elasticity, thereby reduced the phenomenon on fried limit, hard-edge complex cement packaging bag edge.
Because such scheme is reserved the not bonding of certain-length on the both sides of complex pocket, thereby has reduced the breakage of packages rate.
Below in conjunction with drawings and Examples the utility model is done limit one step explanation.
Fig. 1 is a cement package bags profile scheme drawing.
Fig. 2 is a bag of cement section structure enlarged drawing.
Among Fig. 1: 1, soft limit compound cement bag.
Among Fig. 2: 2, outer paper, 3, netty compound material, 4, internal layer paper, A～B is bonding zone not, and A～C is a bonding zone, and C～D is bonding zone not, and B～D is a bonding zone.

#The soft limit of cement complex pocket 1 is an example, and by outer paper 2, netty compound material 3 and internal layer paper 4 is formed, in producing recombination process, reserve in A～B, C～D zone not bonding, more than the length 5mm, bonding in A～C, B～D zone.Not not bonding by A～B, C～D certain-length, increased edge movable elasticity, reduced the phenomenon that the pressure that causes because of packing cement causes the fried bag of edge damage, broken rate thousand/30 that can cause from original hard-edge cement package bags are reduced to millesimal point about five to 40, greatly reduce the breakage of packages rate.
Claims (1)
1, a kind of soft limit complex cement packaging bag is made up of outer paper, netty compound material, internal layer paper, and it is not bonding that certain-length is reserved on the both sides that it is characterized in that complex pocket, and all the other are partly bonding.
