Jis Z 1707 [best]

JIS Z 1707 is the Japanese Industrial Standard titled "General Rules of Plastic Films for Food Packaging."

3. Test methods

• Adhesion strength: The peel adhesion test (Clause X) references [JIS Z 0237 / other]. This is appropriate.
• Holding power / shear: The draft specifies [temperature / weight / time].
• Thickness & width: Tolerances are [too tight / adequate / too loose] for practical manufacturing.
• Aging resistance: [Missing / incomplete] accelerated aging conditions.

Heat Sealing Properties: Since most food packaging is heat-sealed to maintain freshness, JIS Z 1707 defines methods for measuring seal strength to prevent leaks or "breeches" in the barrier. jis z 1707

4.4 Tear Strength (JIS K 7128, Trouser method)

• Type 1: ≥ 20 N/cm (MD and TD)
• Type 2: ≥ 35 N/cm (MD and TD)

10. Environmental Considerations and Future Revisions

10.1 Biodegradability – Not Currently Required

JIS Z 1707, as of its latest revision, does not require biodegradability. However, a study group within the JSA is evaluating: JIS Z 1707 is the Japanese Industrial Standard
