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.
摘要翻译：吸烟制品包括烟草杆和双重过滤器，其包括由醋酸纤维素丝束制成的烟草杆端部段和由聚集的穿孔聚合物膜制成的口端部分，其与增白剂混合以产生基本上无染色的口端表面。聚合物膜还可以包括共挤出的风味薄膜，其具有设置在一对阻挡层之间的香味载体层，用于在吸烟期间将香料释放到主流烟中。可以使用透明包装从构成部件构造香烟，使得过滤棒的过滤表面通过包装可见。

摘要： A cigarette has a blend of tobacco materials and a filter element provided from a non-woven thermoplastic material. The non-woven material comprises polyester or polypropylene fibers. The non-woven material is in intimate contact with a high molecular weight material (e.g., an emulsifier or another polymeric material). As such the filter material is coated with another polymeric material. The coated non-woven material can be in intimate contact with an acidic material (e.g., lactic acid) or a basic material (e.g., sodium hydroxide). Certain cigarettes can have relatively high nicotine smokable blends and filter elements having the coated non-woven filter material in intimate contact with an acidic material. Certain other cigarettes can have relatively low nicotine smokable blends and filter elements having the coated non-woven filter material in intimate contact with a basic material. Certain other cigarettes can be "ultra low tar" cigarettes including filter elements having the coated non-woven filter material in intimate contact with a basic material.
摘要翻译：香烟具有烟草材料和由非织造热塑性材料提供的过滤元件的混合物。无纺材料包括聚酯或聚丙烯纤维。非织造材料与高分子量材料（例如乳化剂或其它聚合材料）紧密接触。因此，过滤材料涂覆有另一种聚合材料。涂覆的无纺材料可以与酸性材料（例如乳酸）或碱性材料（例如氢氧化钠）紧密接触。某些香烟可以具有相对较高的尼古丁可吸收的混合物和具有与酸性材料紧密接触的涂覆的无纺布过滤材料的过滤元件。某些其他香烟可以具有相对较低的尼古丁可吸收混合物和具有与基础材料紧密接触的涂覆的无纺布过滤材料的过滤元件。某些其他香烟可以是“超低焦油”香烟，包括具有与基本材料紧密接触的涂覆的无纺布过滤材料的过滤元件。

摘要： An all polymeric, die cuttable symmetrical lidding laminate for a container which is heat sealable to and peelable from the container. In one embodiment, the laminate structure comprises a core layer of a biaxially oriented voided polypropylene film to the opposite sides of which first and second outer layers of a nonvoid-bearing biaxially oriented polyester film are adhesively laminated to form a symmetrical or balanced laminate structure. A heat seal layer or coating is applied to one side of the laminate structure. A static charge dissipating layer or coating is applied to the other side of the laminate structure. The laminate has sufficient stiffness to be readily die cuttable, has excellent lay flat characteristics, remains substantially curl-free when exposed to heat from either side and is readily denested from a stack of lids during package processing.

摘要： The invention provides a packaging laminate which is heat sealable to polypropylene, high density polyethylene or linear low density polyethylene to provide a strong seal which is cleanly peelable at the heat seal interface under hand pressure. The laminate has at least two layers. A heat sealable surface layer is composed of a melt blend comprising between about 55 and 95 wt. % of a substantially linear polyolefin and between about 5 and about 45 wt. % of a polyolefin rubber. The second layer is a heat stable layer which is structurally stable at temperatures in excess of 350.degree. F. or greater and which has sufficient thickness to provide structural stability during heat sealing.
