Automatic Horizontal Stretch Wrapper

Model: WRWA-200

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.
