Abstract
Invention relates to a multilayer article comprising successively: a non-woven layer of fibers (3) comprising at least 50% by weight of at least one biodegradable polymer melting point of which is below 220° C.; a layer of food-safe adhesive (2); a cellulose-fiber based support (1).
Claims33
A thermoformably shapeable multilayer article for a food product comprising:
- (i) a non-woven fiber layer comprising at least 50% by weight of fibers formed of at least one biodegradable polymer which comprises polylactic acid (PLA) having a melting point which is below 220° C., a thickness between 75 and 150 micrometers and a weight between 10 and 30 g/m2;
- (ii) a cellulose-fiber based support layer which comprises a greaseproof paper;
- and
- (iii) an adhesive layer comprised of a food-safe adhesive selected from the group consisting of acrylic adhesives, polyurethane adhesives and vinyl ethylene acetate, the adhesive layer adhesively joining the non-woven fiber layer to the cellulose fiber based support layer.
