The cork packing system must guarantee the conservation of the manufacturing parameters not only during transport but also during the period of time they will be stored in the wine cellar.
The polyuthene bags usually used to pack corks do not ensure a hemeric seal as they are micro-porous.
PARRAMON EXPORTAP uses double-layer aluminised polythene bags suitable for food use that ensure total protection from external odours, humidity and UV rays and which, furthermore, guarantee the vacuum seal and the inert interior atmosphère for more than 6 months.
