South Australian law on single-use plastic packaging coming into force on 1 September will ban polyethylene containers known as shoyu-tai in Japan

The device known as shoyu-tai (or soy-sauce snapper in Japanese) was invented in 1954 by Teruo Watanabe, the founder of Osaka-based company Asahi Sogyo, according to a report from Japan’s Radio Kansai.

It was then common for glass and ceramic containers to be used but the advent of cheap industrial plastics allowed the creation of a small polyethylene container in the shape of a fish, officially named the “Lunch Charm”.

The invention quickly spread around Japan and eventually worldwide, and it is estimated that billions have been produced.

    A decent question. Especially if this ban allows the ripper pouch style single serve sauces.
    I have collected a tonne of the fish shaped bad boys at river clean ups, so maybe they’re somehow worse. Tbh takeaway sushi could improve in a lot of ways to reduce single use plastics, so kinda funny that the cute fish copped it.

      If it hasn’t already been broken down into microplastics yet and it’s floating around in its whole form, then other organisms that eat fish that size could think it is a fish and then eat it,” Wootton said.

      And:

      “Since they are quite a thick plastic, it does take quite a while for them to degrade.”
