Toppan Develops TOPMER Adhesive for Digital Printing

Toppan Printing, a global leader in communication, security, packaging, décor materials, and electronics solutions, has developed a high-strength adhesive for digital printing. TOPMER™ is suitable for retort sterilization, boiling sterilization, and heating in microwave ovens, thus expanding applications for packages employing digital printing and enabling high-value-added products that meet the diversifying needs of today’s consumers.

TOPMER™ will go on sale in Japan on February 24 targeting the food, toiletries, and cosmetics sectors.

TOPMER is a high-strength adhesive that can be used for lamination on conventional general-purpose machinery. This means that in addition to packaging that undergoes retort sterilization, digital printing can now also be applied to packages for boiling sterilization and microwave heating, something that was previously not possible.

Toppan has reportedly improved resistance to heat and water, meaning packages are suitable for retort sterilization at 130 degrees Celsius for 30 minutes and can also withstand boiling sterilization over long periods.

Digital printing makes it possible to apply original designs to small lots, eliminating the need to affix labels to ready-made plain pouches and helping to alleviate labor shortages. In contrast to conventional mass production methods for printing on flexible packaging, cylinders are not necessary, allowing multiple design variations to be created for the same package.

Toppan has reportedly applied its extensive information processing technologies to achieve quality equivalent to that of gravure printing and enable the production of packages that stand out in stores. The technology also facilitates test marketing, limited edition package ranges, and a host of other possibilities, while the ability to produce only the required quantity of a given package when it is needed prevents excess inventory and contributes to more eco-friendly solutions that help reduce waste and loss.

TOPMER will be on display in the Toppan Booth (S1-12, South Hall 1) at TOKYO PACK 2021, which will be held at the Tokyo Big Sight exhibition center from February 24 to 26.
