ReZilok Rx - Tie-Layer Resin - Brochure

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.
