Thermoplastic starch materials and methods of making the same are provided. The methods involve mixing a starch material, plasticizer and water in a low-shear mixer under conditions that will result in substantial gelatinization of the starch material. The melt formed within the mixer is discharged into an extruder for final processing. The methods prevent degradation of the starch material thereby resulting in the formation of a thermoplastic starch material having high strength, due at least in part to the preservation of the molecular weight characteristics of the starch, and improved elasticity due the ability to use higher water contents than conventional processes.

The proposed product relates to the field of manufacturing packaging for primarily liquid, fatty, and frozen food products or for products that contain or release fats and moisture. The present packaging, having an overlapping seam with a sealed end face, is made of a shape-giving material that consists of a base material and a protective layer applied on one side of said base material. The protective layer is elongated relative to the base material, and at the place where the shape-giving material is joined in an overlapping fashion to form a seam, the elongated protective layer is connected on the inner side of the packaging to the adjoining layer of shape-giving material without the protective layer coming into contact with the end face surface of the shape-giving material, to protect an end face without thickening the material at an overlap point and without the overlap point being excessively rigid, as well as without using an additional protective polymer tape or an expensive base material having hydrophobic properties.
