Mitre Seal bags & K-Seal bags

Inside the base at the bottom of a normal gussetted box liner, you find four pockets that are formed naturally.  When used in combination with grains or powders, these pockets can cause loss of product.  Thats why Mitre Seal bags and K-seal bags are now primarily used in the food processing industry.  This is because these bags, liners and covers are manufactured to eliminate food waste or loss of product.  When we manufacture the liners we apply an additional mitre seal on the four gusset panels to close these pockets. These are sometimes referred to as Cross corner seal bags.

If you would like to know more about these types of product, please get in touch and we will happily assist or provide samples.

Other uses for the mitre seal and k seal is in cross corner seal box covers.  This is where the same seal is applied to U-fold sheets to create a cross corner seal tray liners or dolav cover. We can also produce dolav liners.  Have a look at our mitre seal covers and mitre seal dolav liners leaflets.
