: Evaluates the material's flexibility. Under standard guidelines, an elongation value below 10% is classified as poor , whereas values above 50% are considered good for flexible food application.

To meet JIS Z 1707 certification, films must undergo rigorous testing to ensure they protect food quality while remaining safe for consumers. Key parameters include: Tensile Strength & Elongation: jis z 1707

For specific details on JIS Z 1707, I recommend consulting the Japanese Standards Association (JSA) or a relevant industry body that could provide the most accurate and up-to-date information on this standard.

Understanding a standard's history is key to appreciating its current content. JIS Z 1707 has undergone several significant revisions to align with technological and market changes. : Assessed using a hemispherical needle (radius :

This is a critical chemical test. The film is immersed in solvents (simulating different types of food—e.g., water for aqueous foods, heptane/ethanol for fatty foods) for a set period. The amount of chemical substances that "migrate" from the film into the solvent is measured. This must remain well below the safety threshold to prevent toxicity. Key parameters include: Tensile Strength & Elongation: For

However, note that newer standards like (for general PE films) or international ISO 15494 are sometimes preferred for non-Japanese supply chains.
