The invention relates to treated cellulosic fibers comprising internally dispersed cuprous oxide (Cu.sub.2O) nanoparticles, methods of preparing such treated cellulosic fibers, and uses of such treated cellulosic fibers.

Described herein is a process for preparing a flexible packaging material. The process may comprise: providing a printed first flexible substrate comprising an ink composition on a surface of a first flexible substrate, the ink composition comprising a first thermoplastic resin; depositing a further composition comprising a cross-linker, a white pigment and a second thermoplastic resin onto the printed ink composition such that the thermoplastic resin of the ink composition is cross-linked; and laminating the first flexible substrate with a second flexible substrate such that the ink composition, the further composition and the cross-linker are disposed between the first and second flexible substrates.

The present invention provides coated films and packages formed from such films. In one aspect, a partially coated film comprises (a) a film having two outer surfaces, wherein a first outer surface is provided by a film layer that comprises from 70 to 100 percent by weight of a polyolefin having a density of 0.860 to 0.965 g/cm.sup.3; and (b) a coating on the first outer surface of the film comprising polyurethane, wherein the coating covers less than 25% of the surface area of the first outer surface of the film and wherein the coated portion of the film exhibits an Elmendorf tear in at least one of the machine direction or cross direction that is at least 20% less than the Elmendorf tear of the uncoated portion in the same direction, with the Elmendorf tear being measured in accordance with ASTM D1922.

The present disclosure is directed to pharmaceutical packages which include a coating that comprises polycyanurate, and methods for the production of such. In one or more embodiments of the present disclosure, a pharmaceutical package may comprise a glass container comprising a first surface and a second surface opposite the first surface. The first surface may be an outer surface of the glass container. The pharmaceutical package may further comprise a coating positioned over at least a portion of the first surface of the glass container. The coating may comprise polycyanurate.

An apparatus includes a flexible container and a port. The container includes a first layer coupled to a second layer to define a storage volume within which a tissue specimen can be contained. The first layer has a first stiffness and the second layer has a second stiffness. An edge of the first layer is spaced apart from an edge of the second layer to define an opening into the storage volume. The edges of the first and second layer form a peelable seal that hermetically seals the storage volume such that the first layer can be peeled away from the second layer to expose the storage volume. The port is coupled to the flexible container and allows fluid communication between the storage volume and an external volume.
