Automatic Packaging Line With Tray
Automatic Packaging Line With Tray Typical Applications
- Bakery products: mooncakes, pastries, bread rolls, sliced cakes.
- Confectionery & snacks: chocolate assortments, delicate candies, multi-piece snack sets.
- Frozen & ready meals: dumplings, dim sum, prepared food portions.
- Special retail packs: promotional combo trays, gift assortments.
An Automatic Packaging Line With Tray is a specialized solution that combines tray loading with pillow bag (back-seal/fin-seal) wrapping to create retail-ready packs that are both protective and visually appealing. It is designed for products that are too fragile or premium to be packed directly into pillow bags, but still require the hygiene and shelf-life benefits of sealed film.
Why use tray-in-bag packaging?
- Tray stability – The tray holds delicate or multi-piece products in place, preventing crushing and deformation during wrapping and transport.
- Film hygiene & preservation – The pillow bag provides a sealed environment that protects against moisture, dust, and contamination.
- Retail presentation – The combination delivers a professional, attractive look that enhances shelf impact.
Step-by-step process explained:
- Product preparation – Biscuits, cakes, or confectionery items exit the cooling line and are aligned for feeding.
- Tray dispensing – Pre-formed trays (plastic, paper, or foil) are automatically placed onto the conveyor.
- Tray loading – Products are counted and loaded into trays via servo pushers or mechanical loaders (robotic pick-and-place optional for complex orientation).
- Film wrapping (pillow bag) – The tray with products enters the flow wrapper, where film is formed around it, creating a back seal and two end seals.
- Optional gas flushing – MAP sealing (e.g., nitrogen) can be added to extend freshness.
- Final discharge – The finished tray-in-bag pack moves downstream for cartoning, case packing, or palletizing.
👉 This dual-layer protection—tray + sealed bag—is especially valuable for bakery, confectionery, and ready-meal manufacturers who need both stability and hygienic packaging.
