The Semi-Automatic Web Sealer with Shrink Tunnel for Bottles (APSTW-120) by AmarPack Machines Pvt Ltd is a heavy-duty packaging system engineered for multi-pack grouping of plastic (PET, HDPE), glass, and aluminum containers. Designed for medium-throughput facilities, this machine integrates pneumatic sealing dynamics with precision thermal contraction to deliver high-integrity, unitized bundle packaging.
Designed for high-demand beverage, pharmaceutical, FMCG, and industrial chemical applications, the APSTW-120 handles diverse packaging configurations (e.g., 2×3, 3×4, 4×6 matrix formats) with consistent web-seal strength and tight shrink tension.
Built on a structural mild steel frame with industrial-grade pneumatic and thermal components, the system integrates seamlessly with motorized roller conveyors and high-efficiency heat tunnels. Whether integrated into semi-automated bottling lines or upgraded from manual operations, it optimizes film usage, minimizes thermal energy consumption, and ensures structural pack integrity during transit.
Heavy-Duty Industrial Construction: Fabricated with CNC-machined, heavy-gauge mild steel frame members coated with anti-corrosive industrial powder cladding to withstand mechanical stress, vibration, and continuous multi-shift operations.
Pneumatic Sealing Arm System: Features double-acting pneumatic cylinders paired with impulse/constantly heated Teflon-coated sealing jaws, delivering uniform cross-seal clamping force and clean film cutoff without residue build-up.
Smooth Film Unwinding with Dancing Roll: Equipped with dynamic tensioning dancing rolls and motorized unwinding mandrels to ensure steady film feed, preventing web tear, misregistration, and film gauge distortion during high-speed cycle initiation.
Multiple Feeding Options: Configurable with manual pusher tables, inline powered belt feeds, or 90° cross-feed pneumatic pushers to adapt to upstream filling, capping, or labeling conveyor heights and orientations.
Easy Film Roll Mounting: Dual quick-change film roll shafts with quick-locking core collars reduce roll changeover downtime to under 3 minutes, maximizing overall equipment effectiveness (OEE).
Compatible with Conveyorized Shrink Tunnels: Pairs with dual-zone forced-air recirculation shrink tunnels equipped with digital PID temperature controllers, variable-speed mesh/rod conveyors, and adjustable air velocity dampers for uniform thermal contraction.
