Tyvek® 2FS has not had any corona or antistatic treatment. This makes it eminently suitable for direct food contact and for use in intelligent packaging to preserve freshness of foodstuffs. Tyvek® 2FS is strong, breathable and at the same time water repellent. These qualities ensure that Tyvek® 2FS is highly compatible with active ingredients in, for instance, absorption pouches such as ethylene removers.
