Tray packing combined with shrink packaging offers a dual-layer protection system for products such as food items, baked goods, electronics, and pharmaceuticals. Products are first organized in trays for stability, then wrapped in shrink film for tamper evidence, dust protection, and enhanced shelf appeal. The system ensures consistent shrinkage and tight sealing without damaging delicate items. Adjustable heat tunnels and conveyors accommodate various tray sizes, product weights, and configurations. This combined approach reduces breakage, maintains product hygiene, and stabilizes items for storage and transport. It also allows manufacturers to produce multi-unit packs efficiently, improving logistics and reducing manual handling. Clear shrink film preserves product visibility and branding, while automation features such as infeed synchronization and temperature control improve throughput and operational efficiency in industrial-scale packaging facilities.
