Toppan Printing Co. Ltd., the parent company of Toppan USA Inc., has developed a new product in its GL Film range of transparent barrier films. 

Its reinforced PET-based GL Film adds enhanced resistance against pinholes to conventional barrier packaging for retort foods. Samples for use in retort food packaging will be shipped in late 2016, and full-scale sales are scheduled to begin in March 2017.

The new product maintains the oxygen, moisture vapor and other barrier properties of GL Film used for retort packaging, but has been reinforced by enhancing the PET film substrate to bring performance close to that of nylon film.

Conventional packaging for retort generally consists of four layers: a heat-resistant resin layer, a barrier layer, a reinforcing resin layer and a heat-seal layer. However, the development of this new product has enabled retort packaging with a minimum of just two layers, company officials say. This makes it possible to cut carbon dioxide emissions from processes up to and including manufacture by around 25 percent compared with conventional retort packaging.

The product is currently being presented at Toppan USA’s booth N-6181 during PACK EXPO through Nov. 9 at the McCormick Place in Chicago.
