Laminates - Bond Strength

Laminates are made by bonding together two or more layers of material or materials. Their performance is often dependent on the ability of the laminate to function as a single unit. If the plies have not been properly bonded together, the performance of the laminate may be compromised. Changes in ambient conditions can adversely affect the bond strength of a laminate. Such is the case with boilable pouches used to store and cook food products.

A Chatillon system may be used to determine the amount of force or energy required to separate plies of materials or materials plus the force required to bend the plies.

Industry standards for determining the bond strength of laminated material are:
- ASTM F-904
