Thickness and Tolerance Control in Rigid Film and Laminates

Thickness looks like a simple number, but its tolerance decides how consistently a pack forms and seals.

Why tolerance matters

• Thin areas form and seal differently from thick areas
• A wide tolerance forces the specification upwards to compensate
• Total thickness in a laminate affects stiffness and achievable draw depth

How it is controlled

• Continuous measurement during production
• In-line monitoring on rigid film lines
• Verified per batch, with records available

Practical advice

Ask for the tolerance alongside the nominal thickness, and check it against your forming window before specifying.
