Perforated cigarette tipping paper

摘要

A cigarette tipping paper is formed in a strip with spark-eroded perforations irregularly distributed in one or more zones extending the length of the strip. Unperforated regions are located along the margins of the strip. This cigarette tipping paper is receivable on the exterior of a filter on a filtered cigarette to form a filter tip having a porosity approaching that of the filter alone.
