Polyester resin foam sheet, which can be used to produce food and beverage containers, which has a density of less than 700 kg / m {sup, 3} and a crystallization rate such that when the material is heated at 120 ° C for 5 minutes, the crystallinity does not reach values greater than 15%. The aromatic polyester resin used to prepare the foam sheet can be mixed with an aliphatic polyester resin to confer biodegradability and / or compostability to the sheet. |
