Selecting the right trays and understanding packed columns (in process contexts) requires clarity on function. Below are practical steps to choose trays for packaging and tips if you meant packed columns used in chemical/process engineering.
Tray selection for packaging
- Define product constraints: dimensions, weight, fragility, ESD sensitivity.
- Material compatibility: food-grade for food, chemical resistance if needed.
- Stacking & nesting: design for shipping density and storage.
- Manufacturing method: thermoforming tolerances, cycle times, and tooling costs.
- Sustainability: choose rPET or recyclable materials when possible.
Packed columns (if applicable)
In process engineering, packed columns use random or structured packing to enhance mass transfer (distillation, absorption). Select packed columns by considering:
- Operating temperature and pressure
- Chemical compatibility and fouling potential
- Required efficiency (HETP) and pressure drop limits
Testing and prototyping
Always prototype trays with 3D prints or small thermoformed runs to validate fit, material behavior, and assembly ergonomics before full tooling investment.
Conclusion
Choose trays based on product protection, logistics, and regulatory needs. If you're dealing with packed columns in industry, apply process engineering selection rules.
