Automatic Horizontal Stretch Wrapping Equipment

A horizontal stretch wrapping system that is safer, stronger, and more reliable than any other horizontal stretch wrapper. The WRWA’s NO THREAD powered prestretch carriage optimizes film performance, using less film without compromising wrapping strength. It features a precise heavy-duty ring bearing gearbelt drive system as well as a carriage with a loading clamp and patent-pending rapid-lock film roll device that makes loading a snap. Everything can be done in the same area, with easy access to the carriage for simplified re-loading. The user-friendly digital panel interface offers multiple mode selection for more flexibility.
