摘要 |
<p>A fibrous bonded sheet material, suitable for conversion into plug wrap for the filter plug in a filter cigarette, is formed by treating a fibrous base web with a polymeric binder (e.g. polyvinyl alcohol), a wet-strength resin (e.g. a polyamide-polyamine-epichlorohydrin resin) and a ketene dimer (e.g. an alkyl ketene dimer). The wet-strength resin may be wholly or partially replaced with a cross-linking agent (e.g. glyoxal). The resultant sheet material exhibits favourable characteristics of air permeability with resistance to the bleedthrough of adhesives used in the production of wrapped filter plug material.</p> |
