If you need something strong we offer a Dual Lock with two slots and two tracks for added strength. These are commonly used on large bags or when package contents are highly valuable. This is an ideal profile because it minimizes the possibility of being opening unintentionally.
The Dual Lock Zipper is also widely used in liquid/viscous applications where the pressure applied by the product might force a single track Zipper open from the inside.
