2 Ply / SE&DEF Level 1

      - The outer layer is made with two layers of extensible Kraft Paper
      - The inner bladder is made with LLDEP (Linear Low Density Polyethylene).  The
        bladder is designed to be impermeable, retaining air for 14 days without loss
        of more than 0.5 psi
      - Air bag end seams are stitched using polypropylene thread coupled with filler
        cord and crepe tape binding.
      - 3 psi max inflation
      - 7 psi average burst
      - For OTR / LTL / TL / Intermodal Containers
      - Manufactured with extensible Kraft Paper

4 Ply Paper / Level 2

      - Outer layer comprised of 4 layers of extensible Kraft paper
      - The inner bladder is made with LLDPE (Linear Low Density Polyethylene).  The
        bladder is designed to be impermeable, retaining air for 14 days without loss
        of more than 0.5 psi
      - Air bag end seams are glued using multiple beads of adhesive glue and a
        special folding procedure resulting in end seams stronger than folded paper
        edges.  This is to maximize the paper’s tensile strengths.
      - 5 psi max inflation
      - 17.75 average burst

 6 Ply Paper / Level 3

      - Outer layer comprised of 6 layers of extensible Kraft paper.
      - The inner bladder is made with LLDPE (Linear Low Density Polyethylene).  The
        bladder is designed to be impermeable, retaining air for 14 days without loss
        of more than 0.5 psi
      - Air bag end seams are glued using multiple beads of adhesive glue and a
        special folding procedure resulting in end seams stronger than folded paper
        edges.  This is to maximize the paper’s tensile strengths.
      - 8 psi max inflation
      - 29.4 psi average burst

 8 Ply Paper / Level 4

      - Outer layer comprised of 8 layers of extensible Kraft paper.
      - The inner bladder is made with LLDPE (Linear Low Density Polyethylene).  The
        bladder is designed to be impermeable, retaining air for 14 days without loss
        of more than 0.5 psi
      - Air bag end seams are glued using multiple beads of adhesive glue and a
        special folding procedure resulting in end seams stronger than folded paper
        edges.  This is to maximize the paper’s tensile strengths.
      - 10 psi Maximum inflation
      - 31.9 psi average burst
