Abstract
A method for packaging a product, wherein a multi-layer material is heated to a temperature for thermoforming of the first main layer and is applied with a skin technique to a support which supports a product. The multi-layer material comprises a thermoformable polymeric material first main layer and a cellulose material-based second main layer. The first main layer has a thickness of between 10 μm and 200 μm and the second main layer has a grammage of between 30 and 250 g/m2. Particular embodiments of the multi-layer material are also provided.
Claims35
A method for packaging a product, comprising the following operating steps:
- a loading step in which the product is positioned on the support;
- a positioning step in which, above the support and the product, a sheet is positioned, constituted of a multi-layer material comprising a thermoformable polymeric material first main layer having a thickness of between 10 μm and 200 μm and a cellulose material-based second main layer having a grammage of between 30 and 250 g/m2;
- one or more heating steps in which the sheet is heated to bring the first main layer to a temperature for thermoforming of the first main layer;
- an extracting step in which air present between the support and the sheet is extracted to create a pressure drop between the support and the sheet and to cause the sheet to adhere at least at a perimetric portion of the support which surrounds a central portion of the support itself on which the product is positioned.
