Kaneson entered the breast milk industry in 1910 and, although far less well-known in China than Pigeon, was the inventor of Japan's first piston breast milk pump and created the world's first breast milk storage bag in 1977. Today, 90% of obstetrics and gynecology hospitals in Japan use milk storage bags.
 
The user-friendly design of products is a well-known label made in Japan, and Kaneson is no exception. Its milk storage bags are divided into two product lines, namely hospital-specific and daily. The similarity between the two products is that there is a small white strip at the opening of the pouch, which can be seen as the Kaneson logo, and this patented design prevents fingers from touching the pouch when opening the pouch, which is more hygienic and safe.
 
In addition, unlike conventional milk storage bags, Kaneson's milk storage bags have a stick-on seal, and after squeezing out the air inside the bag, the bag opening needs to be folded backwards before attaching a record label. Extra care must be taken with this type of sealing, however, as the Kaneson pouch cannot stand on its feet and the milk may leak due to squeezing.
 
The specifications of hospital-specific and daily models vary according to different styles. The overall size of the hospital-specific milk storage bag is small, only 25ml and 100ml. The inlet and outlet of the hospital-specific milk storage bag are cut in a trapezoidal diagonal direction, which makes it easier to pour breast milk into the bottle and reduce spillage.
 
The daily model specifications are more comprehensive, with 50ml, 100ml, 150ml, and 200ml. The pouch is also a separate inlet and outlet cut diagonally, but thanks to its larger capacity, it has a water bottle-shaped design that accelerates the flow of liquids. The unit price of Kaneson's milk storage bags of different specifications is less than 4 yuan.
