Abstract: Post-consumer recycled polyethylene terephthalate (PCR-PET) flake is treated with chelant to reduce discoloration and generation of non-intentionally added substances (NIAS) upon melt-processing for use in making thermoplastic articles from the PCR-PET flake.

Abstract: A polyester article is made to appear lustrously metallic or pearlescent by the addition of polymethylpentene and non-metallic, non-pearlescent colorant; and optionally other functional additives. The colorant can be one or more pigments, one or more dyes, or combination thereof. A stretch blow molded plastic article, such as a bottle, using the polymethylpentene in the polyester can simulate the appearance of a metallic surface or a pearlescent luster even though non-metallic and non-pearlescent colorants are used.

Abstract: Multilayer articles comprising a coating layer comprising resorcinol arylate chain members bound to a support substrate via an optional intermediate tie layer. Adhesion between the layers of the multilayer article is enhanced by modifying at least a part of a surface of at least one of the layers in the multilayer article by a technique selected from at least one of: surface adhesive treatment, surface corona treatment, flame treatment, plasma surface treatment, vacuum deposition treatment, ionization radiation, chemical surface treatment, surface abrasion treatment, and surface texturing treating.

Abstract: A food container has a box base with four side panels and four bottom flaps extending from the respective side panels to close the floor of the box base leaving the top open. The bottom flaps are so designed and glued together that the box sides can be folded flat for stacking and then unfolded into a box structure having its bottom wall closed automatically. The box base provides food-receiving area while carrying and serving the eatery. Raised from the top of the box base are circumferential edges defining a tray top. The tray top carries out the decorative role when it is popped open as is possible thanks to the inventive folding scheme implemented in the tray top. The tray top also has carrying handles for the user. The front face of the tray top in the serving mode can be decorated with various cutouts shaped as interesting objects.

Abstract: A method of forming a multilayer film is disclosed, comprising coextruding a first layer comprising a weatherable composition, and a second layer comprising a polycarbonate composition comprising a visual effect filler, wherein the first and second layers are formed by flowing each of the weatherable composition and polycarbonate composition through separate flow channels in a multi-manifold coextrusion die. The shear stress during extrusion on the polycarbonate composition is greater than or equal to 40 kilo-Pascals.

Abstract: Thermoplastic composition comprising a thermoplastic resin and a phosphorescent pigment with a aluminate matrix expressed by M—Al in which M is at least one metal element selected from calcium, strontium and barium and Al represents an aluminate group, wherein the pigment has been coated with a silicone oil. Objects formed by injection molding of the thermoplastic resin compositions. The compositions of the invention exhibit improved melt flow stability and suffer less from graying upon compounding them in an extruder.

Abstract: A novelty piece is fabricated from a single sheet of paper printed on both sides with indicia in registration. Scoring, perforating and cut lines are provided at predetermined positions and an adhesive is applied at preselected locations and the sheet is then folded and adhered in the folded position. a second fold into an adhered position followed by a trimming yields a completed piece ready for use. The completed piece can be selectively opened into one of two positions to display different indicia. The selective display of different indicia with either opened position can be utilized to create illusions or a multiple selection or fortune telling game.

Abstract: Ionomer compositions which have improved optical properties are disclosed. These compositions comprise ionomers which can be represented as the polymerization product of alpha-olefins having from two to eight carbon atoms, esters of alpha, beta-ethylenically-unsaturated carboxylic acids, metal salts of acrylic and methacrylic acid, and optional alpha, beta-ethylenically-unsaturated comonomers which impart some desired polymer property or properties, such as acidity and/or solvent resistivity. Also disclosed are methods of making these ionomer compositions in a reactive extruder and treating the compositions with acid to impart acidity to the compositions or to only the surface of the compositions.

Abstract: The transparent articles described herein have interspersed small particles with a metallic glint. This appearance is achieved by dispersing metal oxide-coated glass platelets within a thermoplastic matrix. It is desirable to take steps to avoid breaking the glass platelets during the process of preparing these materials.
