The high-density construction translates into a durable film that’s more chemical and water resistant than LDPE film. This woven film is also tear and puncture resistant, so it’s often used for tarps and machine covers.

The 0.005” thick film is flame retardant; it meets ASTM E8410/40 for flame and smoke.
