Abstract:
Soak-in and strike through on the exposed end grain portions of low density or porous wood substrates including alder, birch, pine, poplar, and soft maple are reduced by applying to the end grain a solvent-borne coating composition containing an (i) alkyd resin having a hydroxyl number less than about 150, (ii) acid catalyst and (iii) cross linker. The resin desirably has a number average molecular weight greater than about 2000, and may have a Gardner coloration less than about 3 or may be a short oil alkyd based on coconut oil. By using a reduced hydroxyl number alkyd resin, a reduced cross linker amount may be employed, thereby reducing formaldehyde evolution in compositions made with methylated amino resin cross linkers such as methylated melamine resins.
Abstract:
The present application relates to films and packaging articles having films bonded thereto. Also provided are methods of making and applying multilayered films. Exemplary polymeric films include a first layer adjacent the metal sheet having one or more polyester materials and a plurality of metal flakes disposed therein, and a second layer having a majority by weight of one or more crystallizable polyester-based polymers. Other exemplary films include a first layer adjacent the metal sheet having one or more amorphous polyester materials, and a second layer having a majority by weight of one or more crystallizable polyester-based polymers and an opacifying amount of titanium dioxide filler. Yet other exemplary films comprise an oxygen-scavenging material and include a first layer adjacent the metal sheet having one or more amorphous polyester materials, and a second layer having a majority by weight of one or more crystallizable polyester-based polymers.
Abstract:
The present invention provides compositions useful as a barrier layer in, for example, packaging products. The compositions generally comprise a blend of (i) a polyester material, preferably an aromatic polyester resin such as polyethylene terephthalate (PET) and (ii) a vinyl alcohol material. The blend optionally may further comprise (iii) a polyolefin material (preferably a functionalized polyolefin material, e.g., a BYNEL material); and/or (iv) a polyamide material (preferably an amorphous polyamide material, e.g., a GRIVORY material), that optionally further comprises an oxygen scavenging material. The present invention also provides containers (e.g., containers formed by expansion of preforms) having a multilayered body-forming portion including: a core layer comprising the aforementioned blend, and inner and outer layers of a formable polymer composition. The present invention also provides methods of making such containers.
Abstract:
A flexible bag (10) has an open top configured and arranged for receiving one or more feed tubes (32). The bag (10) preferably includes at least one attachment member (20) adapted and configured to be secured to a support member (47). A fixture (50), (60), (70), (80) is utilized to receive the bag (10).
Abstract:
This invention provides a coating composition for use on a food-contact surface of a container (e.g., a food or beverage can) that includes a polymer having one or more segments of Formula I: —O—Ar—Rn—C(O)—O—R1—O—C(O)—Rn—Ar—O— wherein each Ar is independently a divalent aryl group (i.e., an arylene group) or heteroarylene group; R1 is a divalent organic group; each R is independently a divalent organic group; and n is 0 or 1. Containers comprising the polymer and methods of making such containers are also provided.
Abstract:
An oxygen-scavenging composition is provided that includes an oxygen-scavenging polymer and a catalyst. The oxygen-scavenging polymer, which in preferred embodiments is suitable for use in packaging articles, is a dendritic polymer having one or more oxygen-scavenging groups.
Abstract:
Solutions of polyvinylidene resins with very high vinylidene difluoride content in lactam solvent systems and their uses to form high gloss coatings, especially high gloss clear coatings. The present invention also provides coated articles incorporating these coatings. Advantageously, polyvinylidene fluoride (PVDF) resins with sufficiently high vinylidene difluoride content, as well as a wide variety of thermoplastic and thermosetting resins useful in the practice of the present invention, can be easily dissolved in and then stay dissolved in lactam solvents. Conveniently, these solutions may be prepared at room temperature. The ability to coat such PVDF resins from solution, rather than from dispersions, is a key factor leading to the high gloss characteristics provided by many embodiments of the present invention.
Abstract:
A removable roller surface insert for use with a container of rollable liquid. The insert may, in one embodiment, include a roller surface having an upper edge, and an upper contact portion attached to the roller surface at or near the upper edge. The upper contact portion may be configured to contact an inner sidewall surface of the container at or near the upper rim. All, or substantially all, of the insert may be, when the insert is in a use position, located within a first half of the container, the first half defined by a vertical plane passing through a centerline of the container.
