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.

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.

The hot melt adhesive composition may be dually functional, serving as an elastic component adhesive and a construction adhesive.
Adhesive bleed-through of substrates and build-up of adhesive on process equipment can be reduced or even fully eliminated by increasing the running temperature of circumferential rolls (e.g., nip rollers or idlers) used to compress and adhesively bond the substrates of a laminate structure together, as opposed to the usual cooling of the nip rollers. This method is particularly beneficial when using polyolefin-based hot melt adhesives to form laminates with permeable substrates, such as low basis weight nonwovens, for use in disposable absorbent articles. The method can be used to make a range of laminated structures, such as bi-laminates and tri-laminates.

METALLOCENE POLYOLEFIN BASED LOW ACTIVATION TEMPERATURE HEAT SEAL HOT MELT ADHESIVE
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.
A hot applied, non-crosslinking, non-butyl, sealant. These sealants are composed of olefin polymers, styrenic block copolymers, an ethylene vinyl acetate copolymer, tackifying resins, plasticizers, and preferably inorganic fillers, and organosilane adhesion promoters. Optionally, the sealant may include UV absorbers, antioxidants, pigments, and the like. The sealants are suitable for use as edge sealants for insulated glass (IG) window units.

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.
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.
