Article made of thermoplastic material, which article is rigid and at least partly heat insulating. The article includes a laminate in at least parts of the article. The laminate includes a first and a second layer of solid thermoplastic material (A) and an intermediate layer of expanded thermoplastic material (B) with an average density of 50 - 800 kg/m3. The thermoplastic materials (A) and (B) are the same or compatible materials. The article is manufactured according to a process comprising the steps a) forming of a solid outer layer, b) manufacturing of an intermediate expanded layer and c) the appendage of functional parts such as reinforcing profiles, guiding profiles, stacking profiles, hinge parts, pockets, label holders, profiles or holes for automatic handling, locking devices or the like.
Article en matière thermoplastique, rigide et au moins partiellement calorifuge. Ledit article comprend un stratifié au moins dans certaines parties de celui-ci. Le stratifié comporte une première et une deuxième couche en matière thermoplastique (A) et une couche intermédiaire en matière thermoplastique expansée (B) ayant une densité moyenne de 50 à 800 kg/m?3¿. Les matières thermoplastiques (A) et (B) sont identiques ou sont compatibles l'une avec l'autre. On fabrique l'article par un procédé qui consiste à: a) former une couche extérieure solide, b) fabriquer une couche expansée intermédiaire et c) ajouter les pièces fonctionnelles telles que les profilés de renfort, les profilés de guidage, les profilés d'empilement, les charnières, les poches, les porte-étiquette, les profilés ou les orifices pour la manutention automatisée, les dispositifs de verrouillage ou similaire.
