The flexible, yet industrial #419 spools are constructed with two layers of plastic material and a double 24-gauge wire, close form, metal core. The premium quality of our spools ensures that the lamination bond will remain strong so that the plastic outer layer will tear before delamination of the plastic surface occurs. The pliable core and plastic laminated sheath easily wrap around objects to be bundled. Plas-Ties premium twist tie spools help you achieve maximum performance from your twist tying machines. The sturdy and reusable material provides superior temporary bundling to meet your product application needs. With Plas-Ties genuine twist tying material, you can be assured your product will remain bundled during transport. From the Food Industry to the Industrial Marketplace, our heavy-duty twist tie spools provide optimal closures for your products.
