Thermoformed Packaging Pricing Factors
The cost of your custom packaging depends on several factors:
- Mold Complexity: More cavities and custom features can affect cost
- Material Type: Each plastic has different price points and performance traits
- Part Weight and Size: Heavier or larger parts use more material and time
- Order Quantity: Higher quantities typically reduce your per-unit cost
