ProSys Fill, LLC, a designer and manufacturer of manual, semiautomatic, and fully automated filling equipment, has announced various squeeze tube closing options for sealing plastic, laminate, and metal tubes. Available options for plastic and laminate squeeze tube seals include curved seals, rounded corners, slot/hole punch for hanging tubes on store shelves, as well as custom seals for unique tube presentations that are proprietary to the brand. Smooth, standard, or custom-textured seal patterns are offered. Metal tube closure options include single-, double-, saddle-, or triple-fold, with smooth or wave crimp options. All tube closures can include up to a 12-digit code, with an option for a double-sided code.
ProSys offers three sealing methods to meet specific customer needs: hot air tube sealing, the fastest available method; high-frequency sealing, which uses energy to heat the aluminum and plastic layers of the tube; and ultrasonic tube sealing, in which the tube’s inside seal area is heated by high- frequency friction produced by an ultrasonic horn.
