<p>Polyester resin foamed sheet, mono e biaxially stretched usable for the production of containers for beverages and foods, having a density lower than 700 kg/m<3> and a crystallization rate such that, when the sheet is heated at 120 DEG C. for 5 minutes, the crystallinity does not exceeds 15%. The aromatic polyester resin used for preparing the foamed sheet can be mixed with an aliphatic polyester resin to impart biodegradability and/or compostability to the sheet or with 1-10% by weight of a polyamide.</p> |
