A tear notch in a bag allows it to be easily opened by the customer. The tear notch can be in the side of the bag as well as in the skirt (for pre-opened bags-on-a-roll).
Iso Tear Notch
An Iso Tear Notch is primarily used for applications where the bag will be sterilized. The tear notch is actually a horizontal perforation enclosed by a seal, preventing exposure of the product inside to air and also making the bag very easy for the end-user to open. An Iso Tear Notch requires custom tooling for each bag width.
