ReZilok Rx Tie-Layer Resin
Tie-layer resin designed for the medical device industry
The use of multi-layered films and tubing is commonplace and established in the medical device, pharmaceutical, and packaging industries. Multi-layer construction can be used to target various barrier properties, extending packaging shelf life, or to impose different functionalities in catheter tubing. Each layer is optimized for maximum functionality; thus, the various layers may contain very different chemical structures. Materials with different chemical structures often result in sub-optimal adhesion and delamination when co-extruded directly. Therefore, tie-layer plastic resins are used to bond these dissimilar materials.
ReZilok Rx 101 Tie-Layer Resin is linear low-density polyethylene (LLDPE) grafted with maleic anhydride. ReZilok is manufactured with the stringent quality required by the biomedical industry in accordance with the ISO 13485:2016 standard. Due to the polarity and reactivity of maleic anhydride, ReZilok Rx 101 can be used as a tie-layer in the production of multi-layer co-extruded catheter tubing to bond dissimilar materials.
