Abstract
The utility model mainly relates to a package bag for powdery material. The position of a valve port of the existing composite bag body is glued with square cloth of the valve port, and moreover, the depth of a sealing of the cloth of the valve port is more than or equal to two times of the width of a flanging of a bag body. The utility model is suitable for various powdery automatic fill and package lines and has the advantages of convenient fill, no need of secondary commissure and good stacking performance. Raw material can not be leaked in the process of transportation, assembly and disassembly.
Description
The utility model belongs to the packaging bag of pulverulent material.
The pulverulent material packing of prior art.Major part has adopted paper compound or mould and compile compound packaging bag, the intensity height of these compound bags, moistureproof, the anti-corrosion performance is good, and breakage rate is low in transportation and handling process, but this compound bag is because structural limitations, and its spigot valve port cloth is less, fill powder after, there is the easy expansion of valve port cloth, in transportation or handling process, causes the raw material leakage problem.
The purpose of this utility model provides a kind of and is suitable for the automation canning line, and seals firmly, is difficult for the compound volume valve bag of moulding that causes raw material to leak in transportation and handling process.
The utility model is to paste square valve port cloth at the valve port position of compound bag.The bag flanging width that seals the degree of depth 〉=2 times of valve port cloth.
The compound volume valve bag of moulding of the present utility model is applicable to the automated production needs of the modernized large-scale canning line of various powders, pellet, and rational in infrastructure, and can is convenient, need not the secondary sealing, and piling is good, no leak raw material in transportation and handling process.
The utility model is described in further detail below in conjunction with accompanying drawing:
There is sewing thread 2 at the upper and lower opening position of bag 1 among the figure, on the both sides of bag 1 flanging 4 is arranged, and the top spigot of bag 1 is pasted a square valve port cloth 3, flanging 4 width of the bag 1 that seals the degree of depth 〉=2 times of valve port cloth 3.Compile bag for moulding of standard, the size of valve port cloth 3 is long * wide be 10-20 * 20-40cm.
