An embodiment relates to a multi-layer, biaxially oriented polyester (BOPET) film comprising a food contact substance, wherein the BOPET has a percent release in a retort test after can lamination such that substantially all food contacting the BOPET during the retort test is released. Another embodiment relates to a method comprising applying a food contact material comprising a food contact substance to a multi-layer, biaxially oriented polyester (BOPET) film, wherein the food contact material is prepared at around room temperature without heating.

A tubular for downhole use, the tubular including a pipe, an insulation layer surrounding the pipe, and a protective layer around the insulation layer and comprising a polymer. The protective layer can also include a compression layer adjacent to the insulation layer. There may be reinforcement material in the protective layer, for example encapsulated by the elastomer. The tubular may have bare portions at the ends for manipulation of the tubulars to form a tubing string. A sleeve may be provided using the same layer structure to insulate the bare portions which form joints of the tubing string. The sleeve can also include a base layer.
