Abstract: A low shrink tension packaging film contains a first polymer that is an ethylene-unsaturated carboxylic acid copolymer and a second polymer containing one or more copolymers selected from an ethylene-vinyl acetate copolymer and an ethylene-acrylate copolymer. A molar ratio of a specific structural unit of the first polymer to a specific structural unit of the second polymer is in a specific range, such that the low shrink tension packaging film has excellent optical and mechanical properties and a significantly low tension applied when being shrunk by heat.

Abstract: The present application relates to a pressure-sensitive adhesive composition, a protective film, an optical element and a display device. The pressure-sensitive adhesive composition of the present application has excellent storage stability, exhibits an appropriate low-speed and high-speed peel forces after the cross-linked structure is formed, and has excellent balance of both. Furthermore, the pressure-sensitive adhesive formed by the pressure-sensitive adhesive composition does not leave contaminants in the adherend after peeling, while exhibiting re-detachability. Accordingly, when the pressure-sensitive adhesive composition is applied to, for example, a protective film, it is also advantageous in terms of high-speed processes by being easily peeled off upon high-speed peeling as well as it exhibits an excellent protective effect, thereby being capable of exhibiting excellent antistatic characteristics.
