摘要： A moisture-curable adhesive composition comprises a polymer component selected from a silane-terminated polyalkylene oxide and/or a polyurethane; a plurality of amino-silane modified wollastonite fibers having an average aspect ratio of from about 1.5:1 to about 12:1 and an average fiber length of from about 6 μm to about 825 μm; at least two fillers, wherein one of said fillers is untreated and a second of said fillers is treated with a modifier selected from the group consisting of a fatty acid derivative, a silane, a titanate, and mixtures thereof wherein at least one of said fillers is irregularly shaped; and a rheology modifier. The composition preferably further comprises a plurality of irregularly-shaped crumb rubber particles having an average particle size of between about 0.5 to 1.5 mm. The composition is useful for adhering tiles to surfaces, especially large format tiles to substantially vertically-extending wall surfaces.

摘要： A semicrystalline copolyester resin composition formed by twin screw extrusion of various ingredients includes copolyester resins, antiblock, slip and antifog additives. This semicrystalline copolyester resin can be extruded on to PET film or coextruded with PET resin to form clear PET films with antifog properties. These films with antifog properties are produced in a single step without the use of solvent and does not involve any secondary step for coating a separate antifog layer. This minimizes the cost and time required by a converter to make such clear antifog films. These films containing the heat seal copolyester resin can be heat sealed to clear APET trays. Contents within the trays, such as food, can be seen without fogging on the inside of the film that is used to seal the tray. The seals are strong and the peels are smooth giving a very good packaging performance.

摘要： A low activation temperature heat seal hot melt adhesive for packaging applications based on a blend of metallocene catalyzed polyolefin polymer, tackifying resin, wax and other optional additives. In order to achieve the high viscosity suitable for an extrusion heat seal application, the adhesive composition of the invention is highly loaded with polymer, and thus should have a viscosity of about 50,000 centipoise or more measured at a temperature of 300° F. Accordingly, the hot melt adhesive composition contains about 50% to about 90% by weight of metallocene catalyzed polyolefin polymer, about 5% to about 50% by weight of tackifying resin, about 0.5% to about 40% by weight of wax, about 0.1% to about 5% by weight of a stabilizer or antioxidant, and 0% to about 25% by weight of optional additives. The hot melt adhesive composition must have an activation temperature of about 160° F. or less, and provide a minimum peel force of about 1.0 pound per inch in order to meet the sealing performance requirements for packaging food and other consumer goods.

摘要： A non-pressure sensitive hot melt adhesive for use in mailer applications uses a styrenic block copolymer (SBC) with a hydrogenated mid-block as the primary polymer in the composition. The adhesive contains about 10% to about 50% by weight of the SBC, about 2% to about 30% by weight of a polyolefin polymer as a secondary polymer in the composition, about 10% to about 70% by weight of a suitable plasticizer, about 0% to about 30% by weight of a wax, about 0% to about 50% by weight of one or more tackifying resins, about 0.1% to about 4% by weight of a stabilizer, and about 0% to about 3% by weight of auxiliary additives, so that the viscosity of the composition is equal to or less than about 10,000 cP at 163° C. The formulation balances the cohesive and adhesive strength required to insure the adhesive fails cohesively to prevent paper tear. In addition, the presence of the secondary polymer allows additional oil absorption into the polymer, thus preventing oil from staining the substrates or surfaces without significantly increasing the viscosity.
摘要翻译：用于邮寄应用的非压敏热熔粘合剂使用具有氢化中间嵌段的苯乙烯嵌段共聚物（SBC）作为组合物中的主要聚合物。粘合剂包含约10重量％至约50重量％的SBC，约2重量％至约30重量％的作为组合物中的第二聚合物的聚烯烃聚合物，约10重量％至约70重量％的合适的增塑剂，约0％至约30％重量的蜡，约0％至约50％重量的一种或多种增粘树脂，约0.1％至约4％重量的稳定剂和约0％至约3％重量的辅助添加剂，使得组合物的粘度在163℃下等于或小于约10000cP。制剂平衡了粘合剂失效所需的内聚力和粘合强度，从而防止纸张撕裂。此外，二次聚合物的存在允许另外的油吸收到聚合物中，从而防止油污染基底或表面而不显着增加粘度。

摘要： A method for packaging plastic material using a film to surround the material, and more particularly to a method for packaging a copolyester, and the resulting package formed thereby. The method is preferably a coextrusion process for packaging an amorphous or semi-crystalline copolyester having a low glass transition temperature by extruding it through a die orifice, and coextruding a copolyester polymeric film having a high glass transition temperature to surround the low glass transition copolyester. The coated low glass transition copolyester may then be formed into individual packaged units having a finite size and shape.

摘要： A water based, cold seal, cohesive coating for bonding one or more substrates together to form a flexible package to contain an article, especially useful for snack food packaging. The cohesive coating includes about 25% to about 90% by weight of a natural rubber latex emulsion, about 10% to about 75% by weight of a non-self-crosslinking acrylic emulsion, about 0.01% to about 10% by weight water, and one or more ingredient selected from an anti-foam agent, ammonia, a surfactant, an anti-blocking agent, an inert filler, and a conditioning agent, so that in combination the components total 100% by weight of the composition. The use of a non-self-crosslinking acrylic emulsion provides an improved cold seal cohesive that may be employed with current high temperature converting systems and provides improved adhesion to substrates, enhanced cohesion to itself, reduced blocking and avoids seal deadening.
