: Regulates the rate of moisture movement. Restricting this parameter protects dehydrated foods from clumping and fresh produce from drying out.
The film must possess enough mechanical strength to withstand handling and transport. For example, some bioplastics aim for a tensile strength of at least to meet specific requirements within the standard. Thickness Uniformity:
Compliance ensures that the plastic does not leach harmful substances into the food it protects. Intertek Inform 3. Impact on Sustainable Packaging jis z 1707
A secure seal is vital to prevent leakage, spoilage, and microbial contamination. The standard mandates rigorous peel testing of heat-sealed joints. It defines the minimum force required to separate the sealed layers, ensuring the integrity of pouches, bags, and lidding films under various pressure and temperature conditions. 3. Puncture Resistance
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. : Regulates the rate of moisture movement
It does not apply to multi-layer films that include paper or metal foils. Key Iterations
Document handling and reference materials For example, some bioplastics aim for a tensile
For rolls:
For global manufacturers, adhering to JIS Z 1707 is a strategic necessity when targeting the East Asian market. Japan is renowned for its uncompromising stance on food safety and packaging aesthetics.
It applies to both single-layer and multi-layer plastic films with a thickness of less than 250 µm, though it excludes films that include metal foils or paper. Why It Matters: The "Tests"
