| 4917 is designed as a re-openable closure system for filmic bags. The product consists of a transparent, double sided PP film with red PP liner and is easily cut with a hot wire of bag making machines. The acrylic adhesive is ageing resistant and has widely different adhesion values on each side. This produces a smooth open and close action without leaving adhesive residues. Applications; especially suited for use with very thick filmic materials; an extended liner version 6917 is also available. |
