Application fit & configuration
A product that fits the seal area still needs to pass through the selected tunnel. Send the complete product envelope and finished-pack appearance you need, including any heat-sensitive surfaces.
Automatic-feed L-sealing plus shrink-tunnel packaging
KPW-FL450, KPW-FL550 and KPW-FL750 are current sale models, each with a confirmed listed speed of 15–30 pcs/min.
The machine automatically feeds the product into the L-sealing section, feeds film around the product, seals and cuts the film, then transfers the pack to a shrink tunnel. The system is intended for products with stable dimensions such as cartons, food trays, bottles, daily products and printed items. Final output depends on product size, film, sealing time and tunnel settings.
Compare other formats in the shrink packaging machine category. A related sealing and cutting shrink system is also available for comparison.

Send Product and Film DetailsBuild an evidence-based quotation
Check product height, film allowance, tunnel opening and conveyor loading together; confirm clearance on the selected combination.
Submit film details and representative products; review the finished seal, shrink appearance and product condition in a trial.
Itemize the sealer and tunnel, electrical supplies, air and conveyors separately before approving the layout.
Record accepted packs/minute on the actual sealer–tunnel combination. For running-cost comparison, use metered kWh during a representative run, not a promise derived from nameplate kW.
Ask for a matched sealer/tunnel selection and a shrink-finish trial plan, with each machine and utility requirement itemized.
Include in your inquiry: Product L × W × H and weight; film type and thickness; target finish; output; tunnel preference; utilities and floor plan.
Start with the product or material, its size range and your required output. Use the inquiry form below to provide your contact details; sample shipment and trial scope can then be agreed.
Send requirements for this machineTwo-year warranty: replacement parts and their shipping are free during the warranty period. Lifetime after-sales service is available. A sample-test proposal is not a guarantee of a specific result or a free on-site trial.
