Adhesion

What is an “Adhesion” ?

In laminated film, “Adhesion” refers to the bonding strength between layers (films/adhesives or films/inks etc.).
If adhesion is not strong enough, the followings happen:

• Delamination caused by water ingress when retorting or boiling
• Breakage caused by expansion of heated air during boiling
• Remaining of the sealant film onto plastic container when opening the lid
