A process to produce a laminate comprising coextruding a dynamically vulcanized alloy (DVA) film with an adhesive layer comprising a vulcanizable elastomeric composition through a die to produce the laminate. The process provides a residence time of the vulcanizable elastomeric composition in the melt to partially scorch the vulcanizable elastomeric composition. A melt of the DVA is in contact with the melt of the vulcanizable elastomeric composition in the die for at least 5 seconds, optionally also with a change in the area of the contact between the DVA film and the adhesive layer as it passes through the die, to increase the adhesion between the adhesive layer and the DVA layer relative to a shorter co-residence time. A laminate and a pneumatic tire comprising the laminate are also disclosed.
