Snack food outer wraps, frozen food bags, and confectionery liners often cite JIS Z 1707 for mechanical properties, with additional food safety declarations.
The standard restricts the presence of heavy metals like lead, cadmium, and mercury, which can be present in inferior plasticizers or colorants.
Q1: Is JIS Z 1707 mandatory for selling PE film in Japan? No, it is voluntary. However, most commercial buyers require it as a baseline quality standard. jis z 1707
