Abstract
A smoking article (10) comprises a tobacco rod (12) and a filter (14) connected to the tobacco rod (12). The filter (14) comprises a first filter segment (18, 20) comprising one or more breakable capsules, wherein each breakable capsule comprises an outer shell and an inner core containing an additive. The filter (14) further comprises a hollow tube segment (22) downstream of the first filter segment (18, 20) and positioned between a downstream end of the first filter segment (18, 20) and the mouth end of the filter (14). The hollow tube segment (22) defines a cavity (24) at the mouth end of the filter (14). A plug wrap (23) circumscribes the first filter segment (18, 20) and the hollow tube segment (22), wherein the plug wrap (23) has a basis weight of less than 90 grams per square metre.
