Toppan Leverages Supercritical Fluid to Develop Ultra-Thin-Walled Injection Molded Container
Toppan Printing (Toppan) says it has used supercritical fluid1 and its original molding technology to develop an ultra-thin-walled container roughly 30% thinner than conventional injection molded plastic. The new container is an addition to Toppan’s “SUSTAINABLE-VALUE Packaging” lineup, which is part of the recently launched “TOPPAN S-VALUE Packaging” range targeting added value for society and fulfilling living. Samples will be made available in Japan for manufacturers in the foods and toiletries sectors.
Reduction of plastic resin consumption for injection-molded containers requires the minimum possible thickness when molding is performed, and it has presented challenges in terms of costs, durability and the feasibility of mass production. Thermoforming has generally been considered better for producing containers that need thin walls, but it does not offer the same scope of possibilities for design as injection molding.
