Toppan Printing develops a new grade of its paper-based high barrier
Eco Flat Cup for the filling of alcoholic beverages
- Deformation of the cup due to temperature changes is prevented
and it can be used for alcoholic drinks that require high temperature filling -

Toppan Printing Co., Ltd. (hereafter Toppan Printing; head office: Chiyoda Ward, Tokyo; President & Representative Director: Shingo Kaneko) has developed a new grade for its paper-based high barrier Eco Flat Cup® which can be filled with alcoholic beverages. Full-scale sales will be launched in early September 2012.
This product is being used first for "Kizakura Karakuchi Ikkon" and "Kizakura Junmai Karakuchi Ikkon", two Japanese sake products sold by Kizakura Co., Ltd. (head office: Fushimi Ward, Kyoto, Kyoto Prefecture; President: Shinji Matsumoto).

The Eco Flat Cup, which went on sale in June 2011, is a paper cup that provides a longer shelf life for its contents than previous similar containers due to its high barrier properties and suitability for aseptic filling. As it is made from paper, it is both environmentally friendly and easy to dispose of.
With this new product, the structure of the lid has been improved into a dome shape, meaning that the lid is able to absorb the contraction of air in the container caused by changes in the temperature of the contents. Toppan Printing has been successful in preventing the deformation of the cup and it is suitable for alcoholic beverages that require high temperature filling for sterilization.

This new product will be displayed in the Toppan booth at Tokyo Pack 2012, which will be held at the Tokyo Big Sight exhibition center from Tuesday October 2 to Friday October 5, 2012.

Background to development
The size of the market for noncarbonated alcoholic drinks, such as shocu, sake and fruit wines, was approximately 1.5 trillion yen in 2011. There has also recently been an increase in products in environmentally friendly containers such as PET bottles and pouches.
Alcoholic drinks require high temperature filling for sterilization. In addition to cooling after filling, many low-alcohol products are sold chilled in stores, and with the significant changes in temperature conditions, the volume of the air inside the container contracts and the cup can become deformed.
With this new product, this problem has been solved by giving the lid a structure that absorbs deformation caused by a reduction in pressure, and it can be used for alcoholic beverages that are filled at high temperature and then distributed at room or low temperature.

The features of the product
- Deformation of the cup is prevented by improvement of the lid structure
Because the structure of the lid has been formed into a dome shape, it absorbs differences in volume when the volume of air inside the container decreases due to cooling and refrigeration after filling. Deformation of the cup is prevented.
- Can be used for alcoholic beverages that require filling at high temperature
As it is suitable for high temperature filling, this cup can be used for a wide range of alcoholic drinks that require high temperature sterilization during filling, such as Japanese sake, shochu, and wines. It is also suitable for alcoholic drinks where aroma is important because the lid can be completely removed for drinking.
- Enhancing ease of drinking by improving ease of opening
The ease of opening has been improved by using an easy-opening sealant film on the lid. Enhanced ease of drinking has been targeted by reducing the paper fluff that appears on the flange section after the lid is opened.
- Retention of original flavor over long periods due to enhanced sealing
With previous paper-based cups, storage over long periods was difficult because oxygen entering the cup from the paper seal section caused deterioration of contents and suitability for sterilization was low due to the fact that the quality of the seal with the lid was not high because of the unevenness of the paper on the flange section.
With the Eco Flat Cup, in order to tackle these issues, a new protective method to cover the entire cup using clear high barrier GL Film(*) has been developed, and the unevenness of the seal section has been eliminated with form processing technology. With the improvement of the seal of the lid and the barrier functions of GL Film, it has been possible to reduce oxygen permeation rate and to make not just room temperature aseptic filling, but also high temperature filling possible.
- Sustainability with a paper container
Because the Eco Flat Cup uses paper, a biomass material, as its main material, it is a sustainable next-generation paper container that is environmentally friendly and easy to recycle.
In addition, over 30% of the paper material used for the Kizakura Karakuchi Ikkon and Kizakura Karakuchi Junmai Ikkon cups is from domestic lumber including wood from forest thinning that contributes to forest development. By simply drinking the product, forest thinning is promoted, and it is possible to contribute to the vitalization of the Japanese forest industry and the mitigation of global warming through the development of healthy forests.

This product will be available at roughly the same price as the regular Eco Flat Cup.

Future targets
Toppan Printing will expand sales of this product to the entire alcoholic beverage industry, including Japanese sake, shochu and wines. The company is targeting sales of 3 billion yen for this product and related orders in fiscal 2015.
