Methods of disposing of liquid radioactive medical waste are disclosed. The methods relate to depositing liquid radioactive medical waste into or onto a substrate that includes (a)(i) fibers, or (ii) both fibers and foam, and (b) activated carbon. The substrate adsorbs liquid radioactive medical waste to facilitate safe disposal of liquid radioactive medical waste.

Waste disposal substrates are also disclosed. The waste disposal substrates include (a) at least one layer of fibers, (b) at least one layer containing activated carbon; and (c) at least one layer containing superabsorbent particles. Methods of using waste disposal substrates are also disclosed. Methods of using a waste disposal substrate may include contacting a waste disposal substrate with a liquid fluid, the waste disposal substrate containing: (a) at least one layer of fibers, (b) at least one layer containing activated carbon; and (c) at least one layer containing superabsorbent particles. The liquid fluid, or a component of the liquid fluid, is collected, dissolved, adsorbed, inactivated, destroyed, and/or disposed of within the waste disposal substrate.

The embodiments relate to a polyamide-based composite film that has excellent curl characteristics, mechanical properties, and optical properties, as well as, in particular, is effective in preventing reflection in the visible light region, remarkably reduces the rainbow phenomenon, and achieves a texture similar to that of glass, and a display device comprising the same. There are provided a polyamide-based composite film, which comprises a base film comprising a polyamide-based polymer; and a functional layer disposed on the base film, wherein the in-plane retardation (Re) measured with light having a wavelength of 550 nm is 100 nm to 220 nm, and a display device comprising the same.

A multi-layered packaging film includes (a) an outer print layer, (b) an inner product-side layer, and (c) a lamination layer interposed between the outer print layer and the inner product-side layer.

A multi-layer packaging film structure is disclosed. This packaging film structure includes a barrier web made up of a barrier web core layer, a barrier web skin layer, and a packaging sealant layer. Each of the aforementioned film layers is biodegradable and/or compostable. At least one of the film layers is made up of at least 1 weight percent of poly(3-hydroxypropionate). The packaging film structure may also include a print web or a paperboard substrate.

The disclosed articles, apparatus, methods, and compositions provide for the integration of different and environmentally-friendly processes for extraction, stabilization, and formulation of active compounds with health and/or other benefits from lignocellulosic by-products of food processes. The active compounds can include one or more of polyphenols, flavonoids, o-diphenols, anthocyanins, and phenolic acids. A high-pressure, high-temperature extraction process provides a means to recover a substantial portion of the active compounds from a biomass feedstock. The corresponding extract can be encapsulated, which provides a convenient form for stabilization and delivery of the active compounds into a final product, for example an active packaging material or corresponding actively packaged food item.

An all polyethylene multilayer film structure having alternating layers of (A) a linear low density polyethylene and (B) a high density polyethylene has improved performance properties relative to a film structure in which the (A) and (B) layers are arranged in a block like or random manner.

The present invention relates to oriented, multilayer polyethylene films. In one aspect, a biaxially oriented, multilayer polyethylene film comprises at least one layer comprising: (1) a polyethylene-based composition that comprises: (a) at least 97% by weight, based on the total weight of the polyethylene-based composition, of a polyethylene composition comprising: (i) from 25 to 37 percent by weight of a first polyethylene fraction having a density in the range of 0.935 to 0.947 g/cm.sup.3 and a melt index (I.sub.2) of less than 0.1 g/10 minutes; and (ii) from 63 to 75 percent by weight of a second polyethylene fraction; wherein the polyethylene composition has less than 0.10 branches per 1,000 carbon atoms when measured using .sup.13C NMR, wherein the density of the polyethylene-based composition is at least 0.965 g/cm.sup.3, and wherein the melt index (I.sub.2) of the polyethylene-based composition is 0.5 to 10 g/10 minutes.

A plastic barrier laminate having at least one at least partially crystallized layer containing polyethylene and a nucleating agent, and at least one pigmented layer containing polyethylene and a portion of flake-shaped pigments, wherein the portion of pigments is in the range from 1.5% by weight to 5.0% by weight relative to the weight of the at least one pigmented layer.

A system having a concealed communications element like a telecommunication antenna is described. More specifically, The system has a communications element that is concealed by a highly reflective multilayer polymer optical film 200. The first element of the multilayer polymer optical film is a core layer 202 that is made up of a multilayer optical stack.
