Online L-Sealer Machine with Shrink Tunnel

Overview – Professional Shrink Wrapping Solution for Continuous Production

The Online L-Sealer Machine with Shrink Tunnel – Model APOLST-160 by AmarPack Machines Pvt Ltd is an industrial-grade, continuous inline shrink packaging system. Designed specifically for medium to high-throughput production lines, the APOLST-160 integrates automated film feeding, precision transverse/longitudinal L-sealing, and high-convection thermal shrink dynamics into a single synchronized workflow.

1. Precision L-Sealing Mechanism & Pneumatic Controls

Conveyorized Infeed & Product Sensing: Utilizes high-sensitivity photoelectric sensors (detecting both opaque and clear polyolefin/PVC films) to trigger the automated infeed belt, guaranteeing precise package alignment prior to sealing.
Sealing Technology: Features impulse/constant-heat L-sealing jaws with a Teflon-coated sealing wire/blade system to prevent film sticking, minimize carbon buildup, and deliver high-tensile, leak-proof perimeter seals.
Cycle Rate & Output: Achieves consistent operational speeds of 12 to 15 packs per minute, handling product footprints up to 12” (L) × 16” (W) without interrupting upstream line flow.

2. Thermal Shrink Tunnel Convection Architecture

High-Efficiency Airflow Design: Powered by a ½ HP AC blower motor managed via a Variable Frequency Drive (VFD), delivering controlled, multidirectional heated airflow around the package to eliminate surface air pockets and wrinkles.
Heating Chamber & Insulation: Outfitted with a 48-inch long heating chamber utilizing 10 to 12 stainless steel finned tubular heating elements (750W each). The chamber is encased in 2.5-inch thick glass wool insulation to maximize thermal retention and lower total kWH consumption during continuous shifts.
Precision Thermal Control: Dual digital PID temperature controllers with K-type thermocouple sensors regulate temperatures from 0°C to 300°C within $\pm 1^\circ\text{C}$ tolerance, allowing compatibility with POF, PVC, and PE shrink films.

3. Industrial Frame & Heavy-Duty Components

Structural Integrity: Built on a 16-gauge cold-rolled close-annealed (CRC) sheet chassis with a heavy-duty angle iron base and scratch-resistant powder-coated finish, minimizing operational vibration at a total weight of ~250 kg.
High-Temperature Conveying: Incorporates a continuous, silicon-coated roller conveyor system inside the tunnel window (16” W × 12” H) to prevent bottom film burning while ensuring uniform thermal absorption on all package surfaces.
Electrical System: Standardized for 3-phase 440V industrial power supply, featuring IP55-rated control panel enclosures, emergency stop safety relays, and modular circuit breakers.

Ideal Technical Applications

Pharmaceuticals & Healthcare: Tamper-evident bundle wrapping of medicine cartons, homeopathic kits and diagnostic trays.
Food & FMCG: Moisture-resistant and dust-proof retail shrink wrapping for cookie boxes, tea/coffee cartons and gift hampers.
Stationery & Industrial: Tight, distortion-free film encapsulation for book bundles, diaries, electronic accessory kits and hardware trays.
