CADPAK T
MIL PRF 131 CLASS 1
MILITARY SPECIFICATION
FILM: MIL PRF 131 C1
POUCH: MIL DTL 117 T1 CE S1
Exterior: Tyvek
Recommended Sealing Conditions:
Temperature 375 °F | Pressure 40 PSI | Dwell 1 SEC
Barrier Material: Water vapor proof, Greaseproof, Flexible, Heat-Sealable, Class 1
Application:
This Heavy Duty white film is one of the strongest mil spec films that Shannon carries. The Tyvek exterior layer provides the strength, the foil layer provides the barrier, and the Poly layer enables it to be heat-sealable. A typical application is for large bags that must carry a heavy load. The film does not stretch and is very strong.
Converting:
Film is converted in many ways: 2-seal pouch, 3-seal pouch,stand up pouch and tubing.
Features include: recloseable zipper, tear notch, round hang hole, and sombrero hang hole
