Insect‐resistant laminate films containing microencapsulated cinnamon oil (CO) were developed to protect food products from the Indian meal moth ( Plodia interpunctella ). CO microencapsulated with polyvinyl alcohol was incorporated with a printing ink and the ink mixture was applied to a low‐density polyethylene (LDPE) film as an ink coating. The coated LDPE surface was laminated with a polypropylene film. The laminate film impeded the invasion of moth larvae and repelled the larvae. The periods of time during which cinnamaldehyde level in the film remained above a minimum repelling concentration, predicted from the concentration profile, were 21, 21, and 10 d for cookies, chocolate, and caramel, respectively. Coating with microencapsulated ink did not alter the tensile or barrier properties of the laminate film. Microencapsulation effectively prevented volatilization of CO. The laminate film can be produced by modern film manufacturing lines and applied to protect food from Indian meal moth damage.
