Tray packer

Also known as: Tray former and packer, Tray packing machine

German: Traypacker

In packaging, a tray packer is a packaging machine that forms trays from flat corrugated blanks around a group of products or places products into preformed trays, often followed by shrink wrapping.

  • Intralogistics

In one sentence

A tray packer forms corrugated trays around product groups or fills preformed trays, often before shrink wrapping.

Example

The tray packer wraps a corrugated tray around 12 cans and hands the pack to the shrink tunnel.

How it applies

  • Engineering: Wraparound tray packers fold the blank around the product group and glue it. Combined with shrink wrapping, trays provide stable, retail-ready packs.
  • Operation: Blank quality, glue settings and product grouping determine pack quality. Format changes adjust grouping and folding parts.
  • Safety: Folding and pressing units, glue systems and shrink tunnels create crushing, shearing and thermal hazards. Guarding and interlocks address them; residual risks go into the information for use.
  • Documentation: Provide format change instructions, blank and glue specifications and troubleshooting for common defects such as open glue flaps.

Tray packer vs. case packer

A tray packer makes an open tray pack; a Case packer fills closed cases. Many machines can do both with different formats.
