About the GreenJacket® IMPERMEABLE Material

GreenJacket® material is a five layer film with abcca structure. The two "a" layers of polyethylene resins are extruded and blown into pre-set widths required to produce the finished product. The material consists of virgin outer layers "a" of high-strength linear low-density polyethylene film. (LLDPE) This LLDPE sheeting is then slit into two panels, which are then rolled onto heavy-duty 6" cores. The two rolls of film are then taken to a laminator where a molten layer "b" of polyethylene is extruded between the layers of film onto the two scrim "cc" reinforcement layers. The heavy scrim reinforcement laminated between these plies greatly enhances tear resistance and increases the flexibility and service life of the film. The heavy-duty reinforcement layers are made of 1000 denier scrim laid in a diagonal pattern spaced 3/8" apart. It responds to tears immediately by surrounding and stopping the tear. The white outer layers contain UV inhibitors and thermal stabilizers, designed to reduce heat build up.
