A product can be packaged by arranging the product on a support, providing a plastic film above the support with the product arranged between the support and the film sheet, and air tightly fixing the film to the support. The process can be implemented using an apparatus that includes a film supply assembly and a base equipment having an upper side defining one or more receiving areas, each being configured for receiving a respective product loaded support; an upper tool is configured for holding a film portion above the product loaded support and then heat sealing the film portion to the product loaded support. Each receiving area has a flat portion and elongated features protruding above the plane of flat portion.
