Abstract: A tamper evident container includes a tray portion having a base, a sidewall extending upwardly from a perimeter of the base, and a lid portion having an open position and a closed position. The lid portion may be configured to lockingly engage the tray portion in the closed position. A first hinge may be connected to lid portion and tray portion for rotation of the lid portion relative to the tray portion. A tamper evident closure may also be provided having an open position and a locked position, wherein in the locked position the tamper evident closure connects the tray portion and the lid portion when the lid portion in the closed position. A line of weakness is provided in the tamper evident closure which, when broken after the tamper evident closure is in the locked position, permits the lid portion to be moved from the closed position to the open position.

Abstract: A rigid insulating panel comprising an insulating material core with an R-value of at least 2.5 (hr·ft2·° F.)/BTU·in. The insulating material core has opposed first and second surfaces, a pair of spaced-apart longitudinal edges, and a pair of spaced-apart lateral edges extending between the pair of longitudinal edges. At least one of the pair of longitudinal edges and the pair of lateral edges comprises connecting members including a tongue and groove assembly with an inner groove and an outer tongue separated by a substantially S-shaped median wall. The tongue and groove assembly is engageable with the tongue and groove assembly of an adjacent insulating panel to provide a flexible interconnection therebetween. The rigid insulating panel also comprises at least one membrane covering one of the first surface and the second surface. An assembly method for insulating a concrete surface of a building using an assembly of insulating panels is also provided.

Abstract: This present disclosure relates to durable polymers blends comprising a polyamide polymer, a polyester polymer, and an epoxy-based compatibilizer. The present disclosure further relates to devices, processes, methods and uses involving such polymers.

Abstract: The present disclosure provides, at least in part, a composition comprising polylactic acid (PLA), poly(butylene succinate) (PBS), and a compostable polyester such as poly(butylene adipate-co-terephthalate) (PBAT). The present compositions may comprises calcium carbonate. The present disclosure provides, at least in part, an article manufactured from present composition, such as a packaging.

Abstract: The present disclosure provides an article manufactured from PLA, such as a packaging, comprising a hinge. The present disclosure provides a film comprising PLA and impact modifier. The present disclosure provides a PLA material having haze as measure by ASTM D1003 of about 10% or less, about 8% or less, about 6% or less, about 5% or less. The present disclosure provides a PLA material having an impact resistance as measured by ASTM D-5420 of about 2 inches or greater, about 3 inches or greater, about 3.5 inches or greater, about 4 inches or greater, about 4.5 inches or greater, about 5 inches or greater, about 0.5 inches or greater. The present disclosure provides a PLA material having a fold endurance as tested by TAPPI method 511-08 of about 100 cycles or greater, about 125 cycles or greater, about 150 cycles or greater.
