Abstract
La presente invención se relaciona generalmente con el campo de la degradación de tereftalato de polietileno reciclado (rPET), por ejemplo, capas de rPET en empaques de múltiples capas. Por ejemplo, la presente invención se relaciona con un método para degradar el rPET que comprende la etapa de someter el rPET a al menos una cutinasa. El rPET puede ser una capa a base de rPET en una estructura de empaque de múltiples capas comprendida en un empaque. Sorprendentemente, la materia de la presente invención permite la degradación selectiva de las capas que contienen rPET en materiales de empaque de múltiples capas.
