3.1 Raw material

3.1.1

Cork

Quercus variabilis B1., Quercus suber, or tree-like trunks, branches, or pericarp it consists of cork cells that are continuously meristematic to the cork formation layer. The outer skin of the tree can be collected periodically when it reaches a certain age and thickness.

[Note. LY/T 1317-2013, 2.1] 3.1.2 Virgin cork the cork skin that was peeled from the trunk or branch for the first time is commonly called scalp skin.
