Jis Z 1707 [portable] Review

For food contact applications, additional compliance with Japan’s Food Sanitation Act (JFSL) is required, though JIS Z 1707 itself is not a food-contact-specific standard.

The 1997 version, while now superseded, remains relevant for legacy applications and as a reference point. The 2019 edition represents the most up‑to‑date technical requirements, superseding the 1997 edition entirely.

In the modern packaging industry, ensuring food safety while maintaining packaging integrity is paramount. Japanese Industrial Standards (JIS) play a crucial role in maintaining quality control, particularly in specialized fields like food packaging. is a critical standard defining the requirements for polyethylene (PE) films specifically used for food packaging applications.

JIS Z 1707 mandates that plastic films used for food packaging must not release harmful substances into the food. This includes compliance with:

Compliance with is impossible without proper testing. The standard references the following JIS test methods (most align with ISO or ASTM equivalents but have unique acceptance criteria).

The standard addresses several barrier properties critical to food preservation: In the modern packaging industry, ensuring food safety

: Does not apply to multi-layer films containing paper or metal foils. Key Quality Parameters & Standards

JIS Z 1707 specifies COF for inner and outer surfaces (unless unlabeled):

| Test Item | Key Methods | Purpose | | :--- | :--- | :--- | | (水蒸気透過度試験) | Typically performed using the instrument method outlined in JIS K 7129:1992. | Measures the amount of moisture vapor that can pass through a film over time, indicating its moisture barrier. | | Oxygen Gas Transmission Rate Test (酸素ガス透過度試験) | Performed according to the gas transmission rate test method in JIS K 7126. | Measures the amount of oxygen that can permeate a film, which is critical for preventing oxidative spoilage of foods. | Bags for vegetables, fruits, bread, and frozen foods

Japanese manufacturers and those exporting to Japan require compliance to meet regulatory standards.

Without the full details or context of JIS Z 1707, I can provide a general overview of what such a standard might entail based on common industry practices:

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
