Abstract

A bag or liner (10) adapted to collect items comprises first and second thermoplastic body panels (112, 114), and at least one polymeric structure (218). The first and second body panels are joined along a pair of opposing sides and a bottom (20) bridging the sides so as to form an open mouth. The joined first and second body panels form an interior space for collecting items. The at least one structure is a patch, tape or pouch.
