AUTOMATED PACKAGING-FILM TESTING SYSTEMS WITH EFFICIENT LOADING CONFIGURATIONS AND OPERATION

摘要

Automated packaging-film testing systems perform a Hot Tack Test, Heat Seal Test, and/or an Aged Seal Test. The systems include at least one of: (a) side-insertion peel clamps that are configured to releasably grip film specimens using a resilient fluid-expandable member that cooperates with a side insertion finger; (b) film specimen positioning clips to releasably hold film specimens in position prior to testing, (c) a motion assembly comprising a single drive system that supports and moves all lower seal jaws at each testing station in concert, (d) seal jaw pressure control using a closed-loop pressure system without load cells; (e) jaw clips configured to releasably slidably mount a seal jaw to a heater block, an upper heater block release mechanism, and (g) an integrated film guide and film cooling system.
