摘要： A method of adhering substrate surfaces to one another comprises applying a copolyester resin mixture to the surfaces and contacting the surfaces with one another in the absence of heat to form a cold seal. The copolyester resin may be sulfonated and the reaction product of (a) at least two diols comprising ethylene glycol at a mole fraction of at least about 0.25 and (b) at least three diacids or diesters comprising: (i) a sulfomonomer at a mole fraction of at least 0.02, preferably at least 0.07; (ii) at least one aromatic diacid or diester; and (iii) at least one aliphatic diacid or diester. The ratio of aromatic to aliphatic diacids or diesters may be between about 75/25 and about 45/55, and the glass transition temperature of the resin may be between about -25°C and about 15°C. The resin may be solvated and preferably is food grade compliant and compostable.

摘要： A polymer composition for use in a hot melt adhesive comprises at least one semicrystalline, low molecular weight (LMW) propylene-based polymer; at least one essentially amorphous, high molecular weight (HMW) propylene-based polymer; and at least one essentially amorphous, LMW propylene-based polymer. A hot melt adhesive composition further contains a tackifier, a plasticizer, an antioxidant, and optionally a wax, a filler, a colorant, a UV absorber, another polymer, or combinations thereof. The hot melt adhesive is useful for a variety of industrial applications where bonding of low surface energy substrates is encountered, including disposable nonwoven hygienic articles, labeling and other assembly applications. Particularly preferred applications include nonwoven disposable diaper and feminine sanitary napkin construction, diaper and adult incontinent brief elastic attachment, diaper and napkin core stabilization, diaper backsheet lamination, industrial filter material conversion, and surgical gown and surgical drape assemblies. The composition demonstrates improved peel strength while maintaining very good creep resistance.

摘要： A fire extinguishing adhesive film includes outer layers of adhesive and an inner fire extinguishing core comprising a layer of resin containing a high concentration of fire retardant. Low levels of fire retardant may be blended into the adhesive layers, although it is preferred that the adhesive be pure. Polyurethane resin allows for a fire retardant loading of 86% by weight in the fire extinguishing core, and therefore provides significantly higher yields of fire retardant per unit area of the film without compromising adhesive performance.

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.
