Abstract
A package for storing perishable goods. Film forming the package has an inner layer that defines an interior surface of the package and is formed from a polyethylene and a tack agent that has migrated to the interior surface to provide tackiness. The tackiness permits cold resealing of the package after it has been opened, without substantially adhering to the perishable goods so that the perishable goods can be non-destructively removed from the package. An outer layer of the film defines an exterior surface of the package and is formed from another polyethylene. The polyethylene of the outer layer is configured to block migration of the tack agent through the outer layer such that the exterior surface is substantially non-tacky.
