Let’s talk about your packaging process.

Flexible feeding options for washdown applications

The Pack 403 HE is built to integrate into washdown-ready production lines for fresh and frozen foods. It supports a range of hygienic infeed solutions—from belt-based transfers with pullnose functionality to robotic pick-and-place loading—ensuring clean handling and smooth product flow.

Infeed systems are available in various washdown-compatible lengths and layouts to fit your space and production goals.

Key capabilities include:

  • Robotic loading across single or multiple legs
  • Product distribution across one or multiple legs
  • Grouping and stacking for multipacks
  • Collating for retail-ready formats
  • Buffering to maintain continuous flow
  • Gap closing and precise metering for smooth infeed timing
  • Product orientation and pre-turning for optimal presentation
  • Cardstock feeders for product support

Syntegon also offers integrated downstream packaging solutions, including cartoning, case packing, and end-of-line automation, for customers who require a complete, connected system.

The Pack 403 HE is available in left-to-right and right-to-left configurations to match your factory layout.

Hygienic design meets high-speed flow wrapping

When your production requires strict sanitation alongside fast, reliable packaging, the Pack 403 HE delivers with precision-engineered washdown construction and advanced servo controls.

  • HD3 stainless steel washdown design — including infeed, finwheels, discharge, and electrical enclosure — minimizes contamination risk and supports thorough, efficient cleaning
  • Robust full-servo control system — ensures long machine life, repeatable operation, and reliable 24/7 performance
  • High output with consistent quality — capable of producing up to 600 packages per minute
  • Decals and laser-engraved scales — support faster, error-free changeovers and day-to-day operation
  • User-focused operation — includes a guided workflow on the HMI, clearly marked changeover parts, and visually intuitive controls like tensioners and finwheel pressure gauges
  • Tool-less access and repeatable adjustments — all settings are easy to understand, adjust, and document directly in the HMI
  • Equipped with the latest Syntegon HMI and Synexio connectivity for improved usability, monitoring, and data driven production
