How to Address Uneven Thickness in Food Tray Production: Application of Multi-Station Thermoforming Machines

2026-04-03

Common Issues in Food Packaging Production

In the Turkish food packaging sector, increasing demand for PET and PP trays highlights a recurring issue: uneven thickness distribution, especially at edges and bottom areas.

Key Factors Affecting Thickness Consistency

This issue is often related to:

Non-uniform heating across sheet zones
Unstable sheet feeding during forming
Insufficient coordination between vacuum and pressure
Mold design and cooling mismatch

Technical Approach with Multi-Station Thermoforming

Multi-station thermoforming machines separate forming, punching, and cutting processes, allowing better control:

Multi-zone heating improves sheet uniformity
Positive and negative pressure enhances forming detail
Servo-driven feeding improves positioning accuracy

Equipment Selection Considerations for Turkey

For export-oriented manufacturers:

Multi-zone heating capability
Positive & negative pressure forming
Stability under continuous operation
