Described herein are active pouches for obtaining selected release rates of 1-methylcyclopropene (1-MCP) therefrom. A pouch is a sealed thermoplastic containment or envelope defining an interior volume that is excluded from free exchange with the atmosphere, yet is permeable to both 1-MCP gas and water vapor. The active pouches enclose and contain a clathrate of 1-methylcyclopropene with α-cyclodextrin (1-MCP/CD). The rate of 1-MCP release from an active pouch subjected to a selected set of humidity-mediated disgorgement conditions may be varied by varying the interior volume of the active pouch relative to the amount of 1-MCP/CD contained within the active pouch.

A three-dimensional reinforced membrane is designed to be inflated and used in various structural applications. A dropstitch or double wall fabric may be reinforced with one or more coatings, such as urethane-based coatings, and may also be laminated in accordance with various disclosed embodiments.

Disclosed is a method for manufacturing a soundproofing board part having improved sound absorption performance. The soundproofing board part is manufactured by using, as a material, a recycled soundproofing material which contains a polyurethane foam having excellent sound absorption performance and impact resilience during the press molding; and by producing a sound absorption part on the back surface of the soundproofing board part through a remolding processing method. Also disclosed is a soundproofing board part manufactured by the method. Accordingly, sound absorption performance of the soundproofing board part is improved by about 20% or greater, manufacturing cost thereof may be reduced by recycled resources utilizing waste sheets, and manufacturing process may be simplified compared the related art.
