AirfloPac(TM) is a patented protective cushioning from IntePac (King City, Ontario, Canada). It consists of reusable multi-chambered LDPE parts with "venturi" air-flow restricting tubes.
Upon impact air is compressed in one chamber and then transferred to others via these air tubes. The compressed air acts as a shock absorber causing the cushioning to rebound to its original shape. Custom shapes and sizes are available.
