Jis Z 1707 =link= Jun 2026

JIS Z 1707 is a critical Japanese Industrial Standard titled " General rules of plastic films for food packaging ". It establishes the foundational guidelines and testing protocols for plastic materials directly in contact with food. Scope & Purpose The standard specifies common requirements for both single-layer and multi-layer plastic films used as food packaging components, such as bags and containers. Thickness Limit: It specifically applies to high-polymer materials with a thickness of less than 250 µm . Exclusions: It does not apply to multi-layer films that include paper or metal foils. Key Iterations JIS Z 1707:2019: The current active version, revised to align more closely with international ISO standards. JIS Z 1707:1997: The previous version, which is now superseded by the 2019 edition. Critical Testing Areas JIS Z 1707 defines several mechanical and physical testing methods to ensure safety and quality throughout the food distribution chain: JIS Z 1707:2019 General rules of plastic films for food packaging

Technical Overview of JIS Z 1707: Industrial Polyethylene (PE) Films for Packaging 1. Introduction JIS Z 1707 is a Japanese Industrial Standard that specifies the requirements for polyethylene (PE) films used primarily for industrial packaging. Unlike general-purpose consumer films, this standard focuses on materials intended to protect goods during storage, transport, and logistics. It is one of the most referenced standards in Japanese manufacturing and export packaging, often cited alongside JIS Z 1538 (heavy-duty bags) and JIS K 6781 (general PE films). 2. Scope of the Standard JIS Z 1707 covers low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), and blends thereof. The films are typically used for:

Waterproof wrapping of machinery, steel coils, and large components. Dust protection for industrial parts. Liner bags for corrugated fiberboard containers (shipping boxes). Overwrap for palletized loads (though stretch film is often covered under separate specifications).

The standard explicitly excludes films for food contact (which fall under the Food Sanitation Act in Japan) and shrink films (covered by other standards). 3. Key Dimensional & Physical Requirements JIS Z 1707 sets mandatory tests for the following properties: | Property | Typical Requirement (Grade example: Type 2) | | :--- | :--- | | Thickness tolerance | ±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 | MD = Machine Direction, TD = Transverse Direction 4. Test Methods Referenced The standard relies on other JIS test methods: jis z 1707

JIS K 7127 – Tensile properties (replaces older K 6730). JIS K 7128 – Tear resistance (Elmendorf method). JIS Z 1702 – Water permeability of packaging materials. JIS K 7114 – Impact resistance by free-falling dart.

5. Classification by Type JIS Z 1707 categorizes films into types based on primary mechanical performance, not chemical composition. Common classes include:

Type 1 – General industrial grade (standard LDPE). Type 2 – Higher strength grade (often LLDPE or blend). Type 3 – Heavy-duty grade for sharp-edged or heavy loads. JIS Z 1707 is a critical Japanese Industrial

Each type defines minimum tensile and tear values. Type 3, for example, requires tensile strength ≥ 29.4 MPa and elongation ≥ 400%. 6. Marking & Identification Compliant film rolls must be clearly labeled with:

Standard number: JIS Z 1707 Type classification (e.g., Type 2) Nominal thickness and width Manufacturer name or trademark Lot number or production date

This traceability is critical for quality audits in automotive or electronics supply chains (e.g., Toyota Production System, ISO 9001). 7. Practical Relevance Today Although JIS Z 1707 was last confirmed (with minor revisions) in the early 2000s, it remains widely used because: JIS Z 1707:1997: The previous version, which is

Japanese buyers often mandate it in purchase specifications for export packaging. Recyclability – Films meeting this standard are generally made from virgin or clean industrial-grade PE, facilitating closed-loop recycling. Compatibility – It aligns with JIS Z 0108 (packaging terminology) and ISO standards (e.g., ISO 4591 for thickness measurement).
