A hermetic package for processed food products. The container and lid are made of plastic materials. The lid snaps on the container lip, or may be heat-sealed thereto. A shrink band embracing the container and the lid rim reinforces the grip and supplements the seal of the lid to the container. For large, elongated packages, the container and lid may be formed with relatively thin, uniform walls, reinforced to afford a homogenous flexural characteristic in the completed package which ensures integrity of the closure, while minimizing failure due to stresses imposed under vacuum or handling loads on the package.
