Jis Z 1707

According to the standard (and various research citations), films must meet specific thresholds for safety and durability: ResearchGate

Assessment and measurement

is the landmark Japanese Industrial Standard that establishes the general rules and technical specifications for plastic films used in food packaging . Established by the Japanese Standards Association (JSA) and the Japan Packaging Institute (JPI), this comprehensive standard ensures that single-layer and multi-layer plastic structures maintain the highest levels of safety, physical integrity, and barrier functionality to protect consumer health and optimize shelf life.

This article provides a comprehensive overview of the standard, its requirements, applications, and why it is vital for food safety and material performance. What is JIS Z 1707? jis z 1707

While JIS Z 1707 itself may not detail thickness measurement, the standard references JIS B 7507 (Vernier, dial, and digital callipers) and other precision measurement instruments. Thickness must be measured with appropriate accuracy and precision, as it directly impacts other properties (strength, barrier, etc.).

| Property | Typical Requirement (Grade example: Type 2) | | :--- | :--- | | | ±10% of nominal (e.g., 0.05 mm, 0.10 mm, 0.20 mm) | | Tensile strength (MD/TD) | ≥ 24.5 MPa (250 kgf/cm²) | | Elongation at break | ≥ 250% (MD/TD) | | Tear strength (JIS K 7128) | ≥ 0.49 N (depending on thickness) | | Impact strength | Specified using the pendulum method | | Water resistance | No water penetration under defined hydrostatic pressure |

: It explicitly does not apply to multi-layer packaging webs that incorporate paper substrates or metal foils (such as aluminum barriers), which fall under separate material-specific JIS designations.

). It excludes multi-layer configurations incorporating paper or metal foils. What is JIS Z 1707

The most critical aspect of JIS Z 1707 is the safety of the materials in contact with food. This includes:

The standard specifies various physical and mechanical properties that films must meet to be considered compliant:

JIS Z 1707 does not exist in isolation. It is part of a larger ecosystem of Japanese (JIS) and international standards. The standard several other JIS documents, meaning compliance with these references is mandatory for full compliance with JIS Z 1707. Key among these are standards for test methodologies, such as:

The standard was notably updated to JIS Z 1707:2019, incorporating stricter safety requirements regarding substance migration, aligning with modern food safety regulations. Key Requirements of JIS Z 1707:2019

It provides a standardized framework for the physical and mechanical properties required of plastic and edible films used in the food industry. GlobalSpec Scope & Application The standard specifies general requirements for both single-layer multi-layer
