A method is provided that allows forming and sealing films to be embossed / debossed with a variety of shapes, including geometric, organic, fractal, and / or combinations thereof, and with a variety of sizes and depths. The texture or pattern is transferred from the insert to the film. The pattern on the forming and sealing film is transferred to the surface of a variety of
protein products, including but not limited to chicken, turkey, beef, pork, and
plant protein products, during the forming, filling, sealing, and
cooking process. The forming and / or sealing insert allows for the formation of knitted nets, elastic nets, extruded nets, tightly woven nets, plastic nets, and / or a variety of thermoformed films with functional and / or decorative embossed and / or debossed features without the use of compression molds and / or release agents for net removal. The forming insert is formed using an additive manufacturing process, allowing for the formation of almost any design into the forming and sealing film.
