The S-Carriage InstaThread Pre-Stretch Film Carriage is engineered with features that reduce material costs, save time, and minimize the potential for accidents. The standard 260% material saving pre-stretch, not only significantly reduces film costs, but it’s also an important feature from a sustainability standpoint, as more and more companies look for ways to reduce their environmental impact. The "drop-in" Insta-thread film change makes changeover quicker and safer. Simply grab the film, pull it through, and close the door. Weaving the film between the rollers is not required, so hands remain clear of the internal components.
