Toppan Printing develops Sosogi Jozu - a standing pouch with improved ease of pouring
A new easy-to-open structure for smooth refilling

Toppan Printing Co., Ltd. (hereafter Toppan Printing; head office: Chiyoda Ward, Tokyo; President & Representative Director: Shingo Kaneko) has developed a standing pouch called Sosogi Jozu (easy pour), with which the ease of pouring out contents has been improved. Full-scale sales will begin in mid-September 2012 targeting the toiletries and cosmetics industries.

A standing pouch is a bag-type container that uses laminated film. The pouch is able to stand by itself because the base section opens out when the pouch is filled with its contents. Standing pouches are widely used as refill packaging in the toiletries sector in particular.

Sosogi Jozu is a standing pouch which enables smooth refilling because the spout section does not close up easily. Using Toppan Printing’ s original bag making technologies, it has been possible to develop a new spout structure in which the top part of the pouch is not sealed but folded back on itself. Since there is no sealed section at the top of the spout, the width of the spout can be increased and the spout can be made into a shape that opens out naturally when the pouch is opened. This means that time required to pour out the contents is roughly 20% less than with conventional standing pouches and ease of pouring has been significantly improved. In addition, ease of opening has been enhanced by improving the shape of the spout.

This 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 >
Due to needs for consideration for the environment and resource saving, the standing pouch market is expanding, primarily focused on refill products in the toiletries market, such as shampoos, conditioners, and detergents. The market is estimated to be worth approximately 25 billion yen. Refill standing pouches are widely recognized as a form of packaging that is environmentally friendly in terms of resource saving. However, there have been demands from consumers for shortened refilling times and packages that are easier to open.
Because standing pouches have a structure that includes a welded seal at the top and bottom of the spout, the spout has been difficult to open and has not opened out easily, meaning that the spout can sometimes close up during pouring into a bottle. In order to solve this problem, in the past manufacturers have tried to improve the ease of pouring by embossing texture onto the spout section film or using plastic parts such as a tube. However, there were still problems such as it not being possible to sufficiently ensure the opening of the spout with embossing alone, and price and outsourced recycling costs increasing when plastic parts were used.
With Sosogi Jozu, a standing pouch with a spout that opens out easily has been created by folding back the top section of the pouch instead of sealing it. By adjusting the shape of the spout, it has also been possible to improve ease of opening. In addition, costs borne by companies for outsourced recycling have been reduced by approximately 5% because plastic parts are not used.

< Features of Sosogi Jozu >
- Improvement in ease of pouring with new spout shape
Due to an original and innovative Toppan Printing bag making technique where the top of the pouch including the spout is not sealed together but folded back on itself, it has been possible to produce a spout that is wide and opens out easily. The time needed to pour out the contents is about 20% less than with a traditional standing pouch with a tube.
- Enhanced ease of opening
Due to the adjustment of the spout shape, the strength required to open the spout has been reduced by about 30%.
- Reduction in outsourced recycling costs
As plastic parts are not used, outsourced recycling costs have been reduced by approximately 5% compared with traditional standing pouches with tubes.

< Price >
While ease of pouring and ease of opening are enhanced, it is possible to offer a price that is approximately 10% lower than the price for standing pouches with plastic parts such as tubes for the same volume.

< Future targets >
In addition to the toiletries industry, Toppan Printing aims to expand the use of Sosogi Jozu and other refill standing pouches to sectors such as cosmetics and food, and is targeting sales of 6 billion yen for these products and related orders in fiscal 2015.
