PAKVF4CWSL is known for its high hot tack strength, wide range of seal ability and ability to seal through contaminates, such as fine powders (i.e., vitamin powders, protein powders, pharmaceutical API's, etc.). It also provides an excellent barrier for oily or greasy products.

The outer layer provides oxygen barrier properties and the FDA approved metallocene poly inner layer provides better puncture resistance than PAKVF4. Ideal for food products.

The combination of outstanding properties of PAKVF4CWSL make it the cost-effective choice in a wide variety of packaging applications.
