EP_3663219_A1

Resumen de: US2020299024A1

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.

A system and process of printing a package of expanded material (e.g., expanded starch, foam or other expanded material). The expanded material can be heated and extruded, poured, sprayed, or otherwise applied in malleable form that sets up to become a porous protective covering for an item to be packaged. In an example, a layer of expanded material is laid down, and the item in a protective covering (e.g., a plastic bag, sleeve, coating, etc.) is positioned on the layer of expanded material. Additional layers or expanded material may be applied, thereby encasing the item. The top surface of the expanded material may be flattened, such as by operation of a roller, press, or cutter. The top surface may be sprayed with a shellac sealant, paint, or other coating, to allow printing of a label on the top surface.

THERMOPLASTIC STARCH AND METHOD FOR PREPARING THE SAME

NºPublicación: WO2020190679A1 24/09/2020

Solicitante:

GREEN DOT BIOPLASTICS INC [US]

Resumen de: WO2020190679A1

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.
