Assemblies of stacked layers of materials are described. The assemblies include functional and structural layers. Functional layers include binderless ceramic materials on woven or non-woven substrates of natural, synthetic, or metallic materials. The layers of functional and structural materials may be configured to transport moisture or heat from an inner surface to an outer surface that is exposed to an ambient environment.

The present disclosure includes a composition that includes an ethylene/α-olefin random copolymer having density of 0.890 g/cm.sup.3 or less, a melting point of 100° C. or less, and a melt index from 0.2 g/10 min to 8.0 g/10 min, a styrenic block copolymer comprising from 1 wt % to less than 50 wt % units of styrene, a tackifier, and an oil. The composition may exhibit an overall melt index of the composition of from 2 g/10 min to 15 g/10 min. The composition can be used as an adhesive in some embodiments. The present disclosure also includes multilayer films that include the composition, which may provide reclose functionality to the multilayer film. The multilayer films that include the composition may provide low initial opening force and improved reclose adhesion through multiple reclose cycles. The present disclosure also includes various types of reclosable packaging articles that include the multilayer films and adhesive compositions.

The present invention provides: a sealant film for packaging liquid contents, which is excellent in manufacture suitability, exhibits the effect of being highly adsorptive against an eluting organic substance that a packaging material inherently contains, and odors generated by decomposition of a package-constituting resin and the like, at the time of sterilization/disinfection treatment, and is excellent in resistance to an odor-taste change for the liquid contents; and a package for liquid contents, produced using the sealant film. A sealant film for packaging liquid contents includes at least an odor adsorption layer, wherein the sealant film is formed from a resin composition containing low-elution polyethylene, the odor adsorption layer is formed from a resin composition containing the low-elution polyethylene and an odor adsorbent, a concentration of eluting TOC contained in a film formed from the low-elution polyethylene is 1.5 ppm or higher and 250 ppm or lower, and the odor adsorbent is an inorganic porous material carrying a chemical adsorbent thereon; and a packaging material for liquid contents and a package for liquid contents are produced using the sealant film.

Disposable insole pads and use thereof are disclosed. The disposable insole pads are multilayer structures comprising a topsheet and a pressure sensitive adhesive, and optionally a backsheet, silicone coating and liner layers. The pressure sensitive adhesive layer allows the disposable insole pads to be positioned, repositioned and removed, making them well suited for daily use and disposal.

The present invention relates to a multilayer film for air purification and a method for manufacturing the same and, more particularly, to a multilayer film for air purification having a thin and uniform shape, thereby exhibiting a high degree of utility as a mask and an air purification filter, as well as having an excellent air purification function, and a method for manufacturing the same. The objective of the present invention is to provide a multilayer film for air purification and a method for manufacturing the multilayer film for air purification, which comprises yellow ocher-activated carbon composite particles capable of removing fine dust, bacteria, odor, VOC, etc. present in the air.

The present disclosure provides a film. In an embodiment, a multilayer film is provided and includes (A) a seal layer, (B) a barrier layer, and (C) an odor control layer. The odor control layer includes an odor control composition containing (A) from 85 wt % to 99.5 wt % of an olefin-based polymer and (B) from 15 wt % to 0.5 wt % of an odor suppressant. The odor suppressant includes a blend of: (i) an ionomer, (ii) particles of zinc oxide, and (iii) particles of copper oxide. The composition has a methyl mercaptan odor suppression value of greater than 45% as measured in accordance with ASTM D5504-12.

An inflatable pet bed for animals which incorporates a method for adjusting the firmness is provided. The inflatable pet bed may have a removable layer which has odor absorbing properties. The odor absorbing layer may be a machine washable carbon absorbing layer. Optional foam support layers may also be included within the interior of the pet bed. An exterior cover may protect the internal layers and may also be machine washable. The product may be compactly stored and transported.

Disclosed herein are polymer-based films (and articles of manufacture made therefrom or comprising thereof). In several embodiments, the film comprises biodegradable polymers. In several embodiments, the film comprises post-consumer recycled material. In several embodiments, the film comprises an odor absorbing agent (e.g., carbon). In several embodiments, an article of manufacture comprising a film as disclosed herein or the film itself is biodegradable.

A smell-proof portable container is provided comprising a portable case and a compartment within the case. The compartment contains a lining comprising an inner layer comprising a non-woven fabric, a middle layer comprising active carbon filtering material, and an outer layer comprising the non-woven fabric. The middle layer adsorbs odor particles and pollutant particles emitted by contents of the compartment. The active carbon filtering material comprises carbon filter fiber with activated carbon. The lining is directed to preventing smells and odors associated with the contents from being externally detectable.

A zeolite formulation has been identified that is to be included in an arrangement of barrier layers allowing for the entrapment of volatile organoleptic compound (VOCs), in particular, odor causing VOCs, between the barrier layers in order to contain the release of these compounds. The entrapment technique allows for extended time to adsorb, absorb or react such VOCs before they can be absorbed by the product surrounded by the packaging. A zeolite formulation of an odor scavenger layer not having any VOC barrier layers within the film is also disclosed having the capability to contain the release of hydrogen sulfide over a period of at least 20 days.
