Abstract
Abstract A protective packing product is formed of a pair of flexible plastic wall members sealed together around the periphery thereof to define a hollow air pocket therebetween. Resilient structure is provided within the air pocket, tending to maintain the capsule thus formed in a fully puffed condition. Air-bleed perforations are provided through the walls of the capsule whereby the capsule may tend to collapse with a damped cushioning protection for a protected instrumentality.
