Description
[Velcro USA Inc.] A registered trademark for a reclosable fastener system first patented in 1952 (U.S.) by George de Mestra, a Swiss inventor (patent expired in 1978). Velcro® is a two-component nylon system in which one component has hooks and the other has loops. When pressed together, the Velcro® hooks firmly grasp the loops. The two components may be separated by pulling. Velcro® produces two types of hook systems: flexible and molded. The flexible woven hooks provide maximum cycle life while the molded hooks provide maximum fastening strength with limited cyclability. Velcro® fasteners work effectively in temperatures ranging from -56C (-70F) to 93C (200F). The fasteners may be attached to substrates by sewing, heat sealing or pressure sensitive adhesives. Factory applied pressure-sensitive adhesives can be acrylic, rubber, or Polyurethane based materials.
Applications
- Fasteners for packages, containers and rolled items
Risks
Nylon becomes brittle when exposed to extremely cold temperatures or ultraviolet light. Any pressure sensitive adhesive should be pH neutral and may fail over time.
