Abstract

Le présent extrait concerne des contenants en polyéthylène à parois fines pour le conditionnement d'aliments tels que fromage cottage, ricotta et crème glacée. Ces contenants ont un point de ramollissement supérieur, qui permet de les « remplir à chaud ») et une résistance au choc élevée (qui est utile quand on fait tomber un contenant de crème glacée).
