CALVF4 is a Mylar bag that consists of a polyethylene layer laminated to an aluminum foil layer, creating the effect of a flexible tin can. It is an effective barrier against light, moisture, and oxygen making CALVF4 suitable for a wide array of uses. It is ideal for food products that require protection from odor, moisture and oxygen to stay fresh and also in industrial or commercial applications where CALVF4's barrier abilities make it suitable for packaging sensitive components.
CALVF 4 is ideal for packaging of critical components where protection against moisture and corrosion is necessary. It has a wide range of uses where a high barrier film is needed with a low WVTR. It is well suited for food packaging, where very low oxygen levels are required.
