An elastomeric laminate is provided. The elastomeric laminate comprises a layer A consisting of a diene rubber composition, a layer B comprising a highly unsaturated diene elastomer B, n layers Ci arranged between the layer A and the layer B, n being an integer≧2, i being an integer ranging from 1 to n, the layer C1 being arranged between the layer A and the layer C2, the layer Cn being arranged between the layer B and the layer Cn−1, the layer Ci being arranged between the layer Ci−1 and the layer Ci+1 for values of i ranging from 2 to n−1 when n>2. Such a laminate has good resistance to separation of the layers which constitute it.

A thermoplastic bag includes raised rib-like elements that allow the thermoplastic bag to expand. The thermoplastic bag further includes side seals having rib-like elements that allow the side seals to expand. Additionally, in one or more implementations, the thermoplastic bag includes one or more of a material formulation, a density of raised rib-like elements, a height of raised rib-like elements, or land areas that provide the raised rib-like elements with a reduced rebound ratio.

Systems and methods are described herein for manufacturing and using roofing membranes that are faster and easier to install than conventional adhesive-only membrane materials. In some embodiments, membrane materials are surface treated using a plasma flow, e.g., a blown-arc plasma flow, atmospheric plasma, corona plasma, or from portable plasma units, generated by passing a compressed plasma-generating gas through an electrical current to form the plasma-treated roofing membrane. The plasma treatments described herein may be applied as part of the manufacturing process, or in-situ at the site of roof installation. In some embodiments, membrane materials have surface chemistries, roughnesses and other surface characteristics that yield desired adhesion properties.

An inner barrel may comprise: a perforated top sheet; a backskin; a core disposed between the perforated top sheet and the backskin; and an insulator coupled to the backskin, the insulator comprising a polymeric material.
