En-Cap™ Sleeves completely surround and encapsulate products for superior shock and vibration resistance. En-Cap™ Sleeves inflate around the item, by locking it within the sleeve and providing a protective barrier of air. En-Cap™ Sleeves are manufactured from a unique durable polymer film with a structure that eliminates damage during shipment. Using En-Cap™ Sleeves will eliminate the need for additional packaging materials, providing an excellent product presentation to your customer.
