Abstract
Seals of see-through air-tight flexible bendable material are cut to conform to the shape and size of food storage containers. A seal is placed over the top surface of food in a food storage container. The seal is pressed down and smoothed out removing all of the air bubbles, visible through the seal. The edges of the seal are pressed against the sides of the container to conform to the shape of the container and smoothed out to remove any air spaces between the seal and the container. Multiple seals may be cut simultaneously from multiple sheets using a cutting die or laser cutter. The seals may be cut and packaged in quantity.
