    摘要： Expanded and extruded polyolefin foams are obtained using environmentally benign non-VOC methyl formate as a blowing agent. The blowing agent can be a blend further including at least one co-blowing agent, preferably an environmentally friendly species (e.g., non-VOC), which is either a physical co-blowing agent (e.g. an inorganic agent, a hydrocarbon, a halogenated hydrocarbon, a hydrocarbon with polar, functional group(s) or any combination thereof), or a chemical co-blowing agent, or combinations thereof. The blowing agent blend can include any combination of methyl formate and one or more co-blowing agents. The polymer foam can include polyethylene, polypropylene or a combination thereof. The methyl formate-based blowing agent blends produce stable foams for various applications, including containers, packaging systems, as well as for insulation and protective cushioning. Processes for the preparation of such foams are also provided.

    摘要： A method of forming a container (100) includes heating two webs of material and indexing the webs into a vacuum thermoformer (40) which forms first (220) and second trays (110) simultaneously, wherein the second tray is disposed within a space of the first tray to define a reservoir (300) therebetween. A portion of the first tray is brought into contact with a flange portion of the second tray, and joined by a heat seal within the vacuum thermoformer. A punch device within the vacuum thermoformer perforates a drain aperture (117) in a central region of the bottom of the second tray, such that the drain aperture is in fluid communication with the reservoir. The cut-out section is adhered to the bottom of the first tray to eliminate the presence of any scrap material. The joined first and second tray is indexed out of the vacuum thermoformer and trimmed to separate an assembled container from the web supply.

    摘要： A foldable plastic slider for straddling relation with a plastic fastener includes first and second profiles. The straddling slider is adapted to close or open the fastener by movement therealong. The slider comprises a transverse support member, first and second legs, first and second separating fingers, and first and second wings. The transverse support member includes first and second opposing sides, an interior surface, and an outer surface. The first and second legs depend from the respective first and second opposing sides of the support member. The first separating finger extends from the interior surface of the support member. The first separating finger is adapted to open the first and second profiles. The second separating finger extends from the interior surface of the support member. The first and second wings are hingedly attached to the respective first and second opposing sides. The first and second wings have respective first and second openings for receiving the respective first and second legs. The first and second wings have respective first and second cross pieces. Each of the cross pieces includes a main body member and a latch. The first and second wings are folded relative to the support member and each of the latches engages one of the respective legs to install the slider on the fastener.

    摘要： Packages with active agents are described. Generally, the disclosed packages have a pair of opposing body panels joined together along a pair of opposing sides and a bottom bridging the sides so as to define a mouth opposite the bottom, a reclosable fastener extending along the mouth, and an active agent. The reclosable fastener includes a pair of polymeric tracks, in which each of the tracks includes a mating element and a fin portion. The mating elements are releasably engageable to each other, and each of the fin portions extends downwards from the respective mating element towards the bottom of the reclosable package. The active agent is associated with at least one of the fin portions for communication with the interior of the reclosable package.
