Antimicrobial compositions comprising aliphatic polyester, and an antimicrobial component effective for antimicrobial activity, and, in some embodiments, an enhancer. Example: blend of poly(lactic acid) polymer (55g) with propyleneglycol monolaurate antimicrobial component (9g), and benzoic acid enhancer (1g). Inventive resin compositions are effective against gram negative and gram positive bacteria, mold and mildew. Preferred compositions comprise materials that are GRAS (Generally Regarded As Safe).

Biocompatible antimicrobial compositions

A method for preparing a flexible film substrate with a low glass transition temperature can be used in the production of an article that retains dimensions and improves the surface smoothness after high temperature processing. The invention, for example, would enable low temperature films such as PET and PEN to be dimensionally stable and ultra flat at conditions commonly used in electronic processing which can typically exceed 200&#xb0; C. More specifically, the methods enable the use of e.g. barrier films based on PET or PEN in OLED/PLED manufacturing.

Methods of manufacturing hardenable dental articles, packaged hardenable dental articles, and methods of packaging hardenable dental articles are disclosed. In various embodiments, the manufacturing may involve molding a hardenable dental material in a mold cavity that may be lined with a mold liner. The mold body may also form the package of the hardenable dental article formed within the mold cavity. In other embodiments, the hardenable dental articles may be provided in mold cavities located in sacrificial mold bodies that may be torn, stretched, softened, dissolved, etc. to release the hardenable dental articles in the mold cavities.

An insert for a mold, particularly a thermoplastic injection mold, including a stamper having an impression surface and a backing surface. The insert also has a support block having a facing surface having a plurality of projections thereon, with the plurality of projections in contact with the backing surface. A quantity of adhesive is disposed between the sides of the projections adhering the facing surface to the backing surface. A method for fabricating such an insert for a mold is also disclosed.
