Heating Overwrapping Sealing Shrink Machine for Carton - CHENGQI

This automatic machine is designed to wrap, sleeve-seal and shrink PE film around cartons and larger items. It is suitable for apparel, beverages, food, chemicals, machinery, hardware, textiles and other industries that require secure carton packaging.

The solution comprises the TFZ-8040 fully automatic straight-feeding sleeve sealer (sealing station) and the BS6040 shrink tunnel (heat tunnel) for final shrink wrapping and finishing.

The sealing machine overall dimension is 1700 mm (L) × 1350 mm (W) × 2200 mm (H) and weighs about 350 kg. The shrink tunnel size is L1800 × W600 × H400 mm; the combined package size is approximately L2850 × W1050 × H1900 mm with gross/net weights around 620/560 kg.

The sleeve sealer requires 380V/50–60Hz, 2 kW. The shrink tunnel requires AC 380V 3-phase 50/60 Hz and 20 kW. Compressed air at approximately 6 kgf/cm² is also required for pneumatic components.

Packing size up to W ≤ 650 mm and H ≤ 380 mm; sealing width up to 800 mm. Packaging speed depends on product size but typically 10–15 pcs/min. Shrink film max width ≤ 750 mm, max roll weight ≤ 35 kg and max film depth ≤ 250 mm.

The machine is designed to work with PE (polyethylene) single-layer shrink film (sleeve type). For optimal results use quality PE shrink film within the specified width and roll weight limits.

Control is handled by a Panasonic PLC and a WEINVIEW 7-inch HMI (man–machine interface) for simple operation. The machine supports automatic and manual modes that can be switched as needed.

Yes. The TFZ-8040 is designed with straight in/out feeding and supports production-line integration to realize unmanned operation when connected to upstream/downstream equipment.

Sealing blades are made of special steel with Daikin Teflon coating to prevent sticking and high-temperature damage. The sealing blade has an automatic protection function to prevent accidental cutting. The unit also includes imported photoelectric sensors for accurate positioning and a pressure device to stabilize light products during processing.

Regular maintenance includes cleaning and inspection of the sealing knife (Teflon-coated), checking sensors, conveyor belts, and heating elements. Consumables primarily include PE shrink film and occasional replacement parts for wear items such as the sealing blade or Teflon tape.

Chengqi provides online support, video technical assistance and free spare parts as part of after-sales service. Each machine comes with a machinery test report and video outgoing inspection to ensure quality before shipping.

Yes. The machine can be customized to meet specific packaging requirements such as modified table heights, conveyor configurations or film handling options. Contact the supplier with your product dimensions and requirements for a quotation.

Check that you are using the correct PE film and that film width and tension are properly set. Verify sealing temperature and dwell time, inspect the Teflon-coated sealing blade for wear, ensure photoelectric sensors are aligned, and confirm shrink tunnel temperature and conveyor speed are correctly adjusted.

Provided after-sales support includes video technical assistance and remote support. On-site installation, commissioning and training availability vary by supplier and region—please contact Chengqi or your local distributor for details and quotes.

Specific warranty terms are determined by the seller or distributor. The machine is supplied with a machinery test report and outgoing inspection video to verify performance; contact Chengqi or your sales representative for warranty details and service agreements.
