But it’s not very easy to produce the beautiful zipper pouch. The laminating technology is the key section. Usually, there are four kinds of problems in zipper bag production: The sealing part between zipper and bag is not smooth. Partial delaminating of sealing part between zipper and bag Dead pleats in the juncture between the zipper end and pouch sealing end Partial delaminating of the juncture between the zipper end and pouch sealing end Through many competitions and analysis among various problematic zipper bags, we think these problems above are connected with the following reasons: The thermal shrinkage of zipper is higher than laminating films’ The melting point of zipper is equal to or higher than heat sealing laminating films’ The sectional area of zipper is too big(see the following picture) The partial heat sealing roll of zipper pouch machine is unreasonable, we suggest using ultrasonic heat sealing equipment The partial heat sealing pressure head is unreasonable( usually it’s too small), The ultrasonic heat sealing equipment doesn’t have enough pressure or output power. The heat resistance of the printing ink on the laminated films is bad. The hardness of silicon rubber pad is not suitable.
