Skip to content This automatic shrink wrapping system integrates an L-bar sealer with a high-efficiency heat shrink tunnel, designed for mass packaging across stationery, food, cosmetics, and hardware industries. Equipped with an imported PLC control system and dual horizontal/vertical photoelectric sensors, it enables seamless online integration with production lines without requiring dedicated operators.
Uses imported PLC program control with built-in safety protection and alarm functions to prevent improper feeding or misaligned packaging.
Features dual-axis optical sensors that easily switch to detect thin, small, or low-profile items, ensuring precise sealing for products up to 500(L) × 430(W) × 200(H) mm.
The sealer features a max sealing dimension of 550 × 450 mm, operating at speeds of 15–25 pcs/min using standard POF shrink film.
The 9kW shrink tunnel operates at adjustable conveyor speeds of 0–15 m/min, delivering uniform heat distribution for tight, wrinkle-free film shrinkage.
