EPE is a closed non-crosslinked polyethylene foam which has been drawn with pure oxygen. Due to its high elasticity and strong resilience Alkozell is ideally suited to compensate for tolerances in the interaction between closure and container mouth. Depending on the application there EPE discs unbacked or laminated. For wine closures we offer laminated sealing discs with PVDC (Polivinylidenchlorid) under the brand name SARANEXÂ® and with an additional tin foil provided at the SaranÂ®Zinnscheiben. The advantage of these disks is the low oxygen permeability and its safety for food packaging.
