This foundational section outlines two primary requirements:
Restrictions on heavy metals and plasticizers that can be used in the plastic manufacturing process. Related Standards & Testing
Limits on the residue remaining after volatile components evaporate from the film, tested in water, acetic acid, and alcohol solutions. 2. Physical Properties (Performance)
If you are in the food industry or manufacturing, you’ve likely come across JIS Z 1707 jis z 1707
A key exclusion is that it to multi-layer plastic films consisting of paper or metal foil as constituent layers. These materials are governed by different standards due to their distinct performance characteristics.

JIS Z 1707:1997 General rules of plastic films for food packaging
is the landmark Japanese Industrial Standard that establishes the general rules and technical specifications for plastic films used in food packaging . Established by the Japanese Standards Association (JSA) and the Japan Packaging Institute (JPI), this comprehensive standard ensures that single-layer and multi-layer plastic structures maintain the highest levels of safety, physical integrity, and barrier functionality to protect consumer health and optimize shelf life.
The JIS (Japanese Industrial Standards) series includes many codes numbered under Z that focus on ergonomics, human engineering, and occupational safety. JIS Z 1707 evolved as Japan’s response to growing concerns about the ergonomic risks of prolonged computer and display use, dating from the late 20th century when VDTs became ubiquitous in offices. The standard reflects empirical findings about visual fatigue, musculoskeletal strain, and the psychosocial aspects of display work. It also draws on international guidance—such as ISO standards on ergonomics of human-system interaction and recommendations from occupational health organizations—while tailoring requirements to Japanese workplace norms and regulatory frameworks. Key Requirements and Standards , ensuring the "seals"
Administered by the Japanese Standards Association (JSA), the latest major update to this framework is , which replaced the older 1997 version. This update addressed evolving demands for safety, globalization, and advanced packaging materials.
: Determines a film's structural vulnerability when exposed to sharp, rigid food items like dried bones, grains, or hard confectionery.
This is the most substantial section of the standard, providing the procedures for evaluating a film's performance. A summary of the key tests from the 2019 edition includes:
