Abstract
A twist tie made of two dissimilar polymers forming a composite tying material that may be twisted upon itself forming a closure for a bag, container or bundle. A flat elongated ribbon like thermoplastic substrate (20) has a thermoplastic monofilament (28) disposed generally in the middle of one side and is bonded in place forming a homogeneous joint (40). Another configuration of the monofilament utilizes a pre-formed irregular shape singly or in opposed pairs. A second embodiment utilizes a ribbon of paper (26) laminated underneath the substrate.
Claims20
A composite polymeric twist tie comprising;
- a substantially flat elongated ribbon like thermoplastic substrate having a first side and a second side,
- at least one thermoplastic monofilament contiguously disposed upon said substrate on the first side forming wings on either side of the monofilament, and
- bonding means joining said monofilament to said substrate into a composite twist tie such that the tie may be twisted upon itself with the monofilament retaining its basic configuration and the wings stretching and bending to conform within a coupled twist.
A composite polymeric twist tie comprising;
- a substantially flat elongated ribbon like thermoplastic substrate having a first side and a second side,
- at least one dissimilar thermoplastic monofilament having dead fold properties contiguously disposed upon said substrate on the first side forming wings on either side of the monofilament, and
- bonding means joining said monofilament to said substrate into a composite twist tie such that the tie may be twisted upon itself with the monofilament retaining its original configuration and the wings stretching and bending to conform within a coupled twist.
