Venting system for ovenable containers

An ovenable laminate comprising:

• an outer flexible structure having at least one overcut;
• an inner flexible structure having at least one undercut wherein the each of the at least one overcuts is paired with one of the at least one undercuts;
• an adhesive layer which adheres the outer flexible structure to the inner flexible structure, wherein the adhesive layer comprises
• at least one adhesive free area disposed within a channel between the at least one overcut and at least one undercut, such that the channel provides for fluid communication between the at least one overcut and the at least one undercut.

An ovenable packaging structure comprising:

• an outer flexible structure having an outer cut line which defines a flap that is separable from the outer flexible structure along the outer cut line;
• an inner flexible structure having an inner cut line which defined an inner portion that is separable from the inner structure along the inner cut line, wherein the inner cut line is off set from the outer cut line, and where in when the inner opening portion is separated from the inner structure, an opening into the ovenable packaging structure is created;
• an adhesive layer disposed at least partially between the outer flexible structure and the inner flexible structure;
• and
• at least one valve disposed between the outer flexible structure and the inner flexible structure, the valve comprising:
• an outer opening within the outer flexible laminate;
• an inner opening within the inner flexible laminate;
• a channel extending between the outer opening and the inner opening, wherein the channel is configured to provide fluid communication between the inner opening and the outer opening.
