The GBPI GBB-A3 is an advanced, specialized container lid film heat seal tester engineered to determine the optimal heat sealing parameters — including sealing temperature, dwell time, and pneumatic pressure — for sealing flexible membrane lidding foils onto rigid and semi-rigid plastic cups, tubs, coffee capsules, trays, and pharmaceutical containers. Built in strict accordance with ASTM F2029 and QB/T 2358, this benchtop sealing instrument eliminates manual laboratory sealing inconsistencies and provides packaging engineers with reliable heat seal qualification data.
Rigid container lidding demands precise sealing control to ensure hermetic leak-tightness while maintaining clean, consumer-friendly peelability without tearing the foil substrate. The GBPI GBB-A3 container lid film heat seal tester utilizes an interchangeable tooling architecture consisting of a precision-machined upper annular heated sealing head and a matching lower container-support nest. Technicians place the empty or filled container into the sliding drawer nest, position the precut lidding film over the cup lip, and slide the tray into the sealing chamber. Upon actuation via front-panel push button or ergonomic foot switch, an overhead pneumatic cylinder drives the heated sealing platen downward with calibrated force, holding the film against the container flange for the exact programmed dwell time.
Interchangeable Custom Tooling for Diverse Containers
The GBB-A3 accommodates standard circular cup diameters ranging from Φ30 mm to Φ150 mm, as well as rectangular, oval, and polygonal custom sealing profiles for ready-meal trays, medical blister packs, and dairy tubs. Tooling changeover takes less than two minutes without complex recalibration.
Dual Independent PID Thermal Regulation
Equipped with dual digital PID temperature controllers, the machine regulates sealing temperatures up to 250 °C with ±1 °C precision. The internal pneumatic air regulator allows fine pressure adjustment from 0.05 to 0.7 MPa, ensuring repeatable heat transfer across different polymer flange thicknesses (PP, PE, PS, PET, and aluminum foil).
The instrument features front-panel digital pressure gauges, high-precision dwell timers, and an integrated safety shield, making it an indispensable asset for food packaging R&D, dairy converters, and pharmaceutical quality control laboratories.
