    摘要: An opaque, biaxially oriented film structure is described which comprises:an expanded thermoplastic polymer matrix core layer within which is located a minor amount of a light-absorbing pigment and a strata of voids; positioned at least substantially within at least a substantial number of said voids is at least one void-initiating particle which is phase distinct and incompatible with the matrix material, the void space occupied by said particle being substantially less than the volume of said void, with one generally cross-sectional dimension of said particle, at least approximating a corresponding cross-sectional dimension of said void; the population of voids in said core and the thickness of said core being such as to cause a degree of opacity of less than 15% light transmission; andat least one void-free thermoplastic skin layer affixed to a surface of the core layer, said skin layer(s) being of a thickness such that the outer surfaces thereof do not, at least substantially, manifest the surface irregularities of said core layer.

    摘要: A cigarette smoking article includes a tobacco rod and a dual filter comprising a tobacco rod end segment made of cellulose acetate tow and a mouth end segment made of a gathered, perforated polymeric film blended with a whitener to produce a substantially non-staining mouth end surface. The polymeric film may also comprise a coextruded flavor film with a flavor carrier layer disposed between a pair of barrier layers for releasing a flavorant into the mainstream smoke during smoking of the cigarette. Transparent wraps may be used to construct the cigarette from the component parts so that the filtration surfaces of the filter rod are visible through the wraps.

    摘要: A flavor burst structure and a method of dispersing a flavorant are disclosed. The flavor burst structure comprises a multilayer film with a flavor carrier layer disposed between barrier layers. The flavor carrier layer comprises a polymeric material blended with a flavorant that is not compatible or is partially incompatible with the polymeric material so that the flavorant desorbs from the carrier layer when one of the barrier layers is removed from the carrier layer. Several package applications are disclosed, including a cigarette package, package tear tapes and the like.
