In packaging vocabulary, packing and trays are related but different concepts. Packing describes the entire process and combination of materials used to prepare products for storage, transport, and sale. Trays, by contrast, are a specific packaging component — typically rigid thermoformed plastic, molded to hold and protect individual items or sub-assemblies.
Packing — the process and system
Packing covers selection of primary, secondary, and tertiary materials, methods (manual, semi-auto, automatic), cushioning, labeling, and regulatory compliance. Good packing balances cost, protection, sustainability (recyclability, rPET), and logistics efficiency.
Trays — a packaging component
Trays are custom-shaped supports used inside boxes or cartons to organize, separate, and protect products. Common in electronics (ESD-safe trays), food (FDA-grade trays), and automotive parts. Thermoformed trays reduce movement and scratch risk during long transport.
How they work together
A packing system often uses trays as a primary or secondary insert: a thermoformed tray (primary) may sit inside a printed carton (secondary), which then goes on a pallet and stretch-wrapped (tertiary). Understanding the roles ensures correct material choice and cost optimization.
Keywords & practical tips
- Use ESD-safe trays for sensitive electronics.
- Choose moisture-resistant materials for humid climates like the Philippines.
- Design trays for reusability when possible to reduce cost and waste.
Conclusion
Think of packing as the comprehensive strategy and trays as one of the most effective tactical tools within that strategy.
