JIS Z 1707:1997 General rules of plastic films for food packaging
: Standards for how well the film resists moisture—crucial for keeping dry goods crisp or wet goods hydrated. Heat Seal Strength : Often tested in conjunction with related standards like JIS Z 0238
Although JIS Z 1707 was last confirmed (with minor revisions) in the early 2000s, it remains widely used because:
Restrictions on heavy metals and plasticizers that can be used in the plastic manufacturing process. Related Standards & Testing jis z 1707
When creating nanocomposite films using materials like coco husks to improve durability, JIS Z 1707 acts as a necessary safety and quality benchmark, confirming that the added nano-materials do not break down in a way that exceeds safety limits. Conclusion
WVTR is a key barrier property, especially for moisture‑sensitive foods. JIS Z 1707 references JIS K 7129 (instrumental method) and JIS Z 0208 (dish method) for WVTR determination.

Compared to some other international standards, JIS Z 1707 is known for its rigorous testing methods regarding odor, taste transfer, and migration limits. Future Trends: Sustainability and JIS Z 1707 Conclusion WVTR is a key barrier property, especially
Based on factory audit data, the most frequent failures when testing to are:
Food contact materials must not transfer harmful substances to food. JIS Z 1707 aligns closely with Japan’s Food Sanitation Act. It dictates strict limits for: (such as lead and cadmium).
