摘要： A method for making a laminate comprises the steps of applying a hot melt adhesive composition in a molten state to a primary substrate and mating a secondary substrate to the first substrate by contacting the secondary substrate with the adhesive composition. The composition comprises a polymer blend based on a low molecular weight semicrystalline propylene based polymer and a high molecular weight essentially amorphous propylene based polymer, both of which are prepared by using single-site catalysts. The composition further contains a compatible tackifier, a plasticizer, an antioxidant, and optionally a wax, a filler, a colorant, a UV absorber, another polymer, or combinations thereof. 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.

摘要： An object of the invention is to provide compositions which have low-temperature heat sealing properties, are free from stickiness, may achieve a heat seal strength controlled within a certain definite range when heat sealing takes place at low temperatures, have small changes in heat seal strength with time, and are such that in the packaging applications, the strength required to open the packages may be easily controlled within a certain definite range, and high-performance packages may be designed. The invention resides in a 1-butene.α-olefin copolymer composition including 99 to 1 parts by mass of at least one olefin polymer (X) selected from propylene polymers (X-1) and ethylene polymers (X-2), and 1 to 99 parts by mass of a 1-butene.α-olefin copolymer (Y) containing 0.1 to 30 mol % of one or more α-olefins selected from α-olefins and having a molecular weight distribution (Mw/Mn) of 1.0 to 3.5 [wherein the total of (X) and (Y) in the composition is 100 parts by mass].
