Shrink Wrapper

A shrink wrapper is packaging equipment that applies shrink film around a product or bundle and then uses heat to contract the film tightly, creating a secure, protective, and often tamper-evident package. It operates through film application, sealing, heat exposure, cooling, and discharge, with key controls including seal temperature, dwell time, tunnel temperature, and conveyor speed.

In manufacturing and distribution, shrink wrappers operate at end-of-line packaging, post-picking, and final staging to stabilize finished goods, bundle SKUs, protect items from dust and moisture, and prepare units for shipment. In high-throughput plants, they run as part of a continuous line where products are loaded, film-sealed, heat-shrunk, cooled, and discharged onto conveyors for stacking, labeling, or scanning. For raw-material or WIP tracking, shrink wrap is applied to palletized lots, mixed-SKU kits, or finished assemblies so lot identifiers, traveler paperwork, and barcode labels remain visible during internal movement. This reduces handling damage and preserves unit integrity across receipt-to-storage-to-ship flow. In regulated packaging settings, side-seal, lap-seal, and vertical continuous-motion systems are chosen based on package geometry and throughput, especially when a line wraps a wide variety of sizes or multipacks directly from filling operations.
