An article is described comprising a first film layer comprising polylactic acid polymer (semicrystalline polylactic acid polymer; amorphous polylactic acid polymer; or a mixture thereof); a second (e.g. polyvinyl acetate) polymer having a Tg of at least 25° C.; plasticizer. In some embodiment, the film layer further comprises inorganic pigment and/or hydrolysis stabilizer. In other embodiments, the film has a net melting endotherm, ΔH, of less than 10 J/g. Also described are methods of making a graphic film.

Film comprising polylactic acid polymer suitable for graphic articles

A composition is described comprising semicrystalline polylactic acid polymer; polyvinyl acetate polymer having a glass transition temperature (Tg) of at least 25&#xb0; C.; plasticizer; and optionally amorphous polylactic acid polymer. In another embodiment the composition further comprises nucleating agent. Also described are films comprising the composition as well as articles, such as a tape or sheet, comprising the film described herein and a layer of pressure sensitive adhesive disposed on the film.

Compositions and films comprising polylactic acid polymer, polyvinyl acetate polymer and plasticizer

Foam compositions are provided including a polylactic acid polymer; second (e.g., polyvinyl acetate) polymer having a glass transition temperature (T) of at least 25&#xb0; C.; and plasticizer. Also described are articles comprising the foam compositions, such as a sheet or hearing protection article. Methods of making and using the foam compositions are further described herein.

A multilayer article including a film layer having a textured first surface and an opposite second surface, wherein the film layer is printable, and a nonwoven material layer bonded to the second surface of the film layer. The film layer may include a semi-crystalline polylactic acid and may be receptive to inkjet printing.

Textured printable nonwoven media

A graphic article comprising a Poly lactic acid (PLA) based film and in particular, an ink layer depicting a graphic is described. The PLA based film comprises a semicrystalline polylactic acid polymer, a second of a polyvinyl acetate polymer having a glass transition temperature (Tg) of at least 25&#xb0; C., and plasticizer. The article is typically a tape or sheet that may further comprise an adhesive (e.g. pressure sensitive) and a low adhesion backsize or a release liner. A method of forming a graphic article using the film of the invention is also disclosed.

In another embodiment the composition further comprises nucleating agent. Also described are films comprising the composition as well as articles, such as a tape or sheet, comprising the film described herein and a layer of pressure sensitive adhesive disposed on the film.

Disclosed herein are ketal amide compounds. The ketal amide compounds are synthesized by the reaction of ketal acids or ketal esters with amine functional compounds. Also disclosed are methodologies useful to make the ketal amide compounds. Also disclosed herein are formulations and articles containing the ketal amide compounds.

Ketal amide compounds, methods of making, and applications

The invention relates to polyketal compounds. The compounds are synthesized by the selective ketalization of oxocarboxylic acids, e.g. keto acids and semialdehydes, and esters thereof with tetrols and higher polyols that products two or more cyclic ketal ester moieties per molecule, wherein the cyclic ketal moieties are situated in a bis-, tris-, or polyketal conformation. The invention further relates to applications of these compounds and subsequent reactions thereof.
