The standard applies specifically to single-layer and multi-layer plastic films intended for food contact.

Definition of Film: For this standard, "films" are high-polymer membranous materials with a thickness less than 250 µm.

Exclusions: It does not cover multi-layer films that include paper or metal foils (e.g., aluminum foil laminates). Key Performance Characteristics

JIS Z 1707 outlines metrological and design specifications to ensure safety and functionality in food preservation. It references several other critical testing standards to evaluate these properties:

Tensile Strength: Evaluated under JIS K 7127, which defines test conditions for the tensile properties of plastic films.

Water Vapor Transmission: Measured using methods like JIS K 7129 (instrumental method) or JIS Z 0208 (dish method) to determine the film's moisture barrier effectiveness.

Dimensional Precision: References standards like JIS B 7507 for measuring equipment (callipers) used to verify physical specifications. History and Context

This standard is part of the broader Japanese Industrial Standards (JIS) system managed by the Japanese Standards Association (JSA). The current version, JIS Z 1707:2019, replaced the previous 1997 edition to reflect modern technical requirements in food packaging safety and material science.

JIS Z 1707:1997 General rules of plastic films for food packaging jis z 1707

JIS Z 1707:2019 is the current Japanese Industrial Standard that establishes the general rules of plastic films for food packaging. It specifies common requirements for both single-layer and multi-layer plastic films used to package food, though it does not apply to films combined with paper or metal foils. Key Technical Requirements

The standard defines several physical and mechanical performance metrics that plastic films must meet to be considered suitable for food packaging:

Tensile Strength: Stipulates minimum and maximum allowable values; for instance, some classes require values <25 MPa.

Elongation: Measures the film's flexibility. Values above 50% are generally considered "good," while those below 10% are considered poor. Some specific bioplastics have been tested against a maximum stipulated percentage of 70% for certain applications.

Puncture Strength: Specifies testing methods and strength requirements to ensure the film can resist tearing or piercing during handling.

Heat Sealing: While often referenced alongside other standards like ASTM F88, it outlines general expectations for the integrity of heat-sealed packages. Standard Details Film Cutter FSC-1525

JIS Z 1707 is the Japanese Industrial Standard for "General rules of plastic films for food packaging." It serves as the foundational regulatory and quality framework for manufacturers and food processors in Japan, ensuring that plastic packaging materials are safe, durable, and suitable for preserving food quality.

While many international standards exist, JIS Z 1707 is specifically respected globally for its rigorous testing methods and strict adherence to hygiene and performance metrics. 1. Scope and Application

The standard applies specifically to plastic films used for food packaging. This includes single-layer films, laminated films (multi-layer), and coated films. It covers:

Safety and Hygiene: Ensuring no harmful substances migrate into food.

Mechanical Strength: Guaranteeing the package won't fail during shipping.

Environmental Resistance: How the film reacts to heat and moisture. 2. Physical and Mechanical Requirements

JIS Z 1707 outlines several critical performance tests that a film must pass before it can be certified for food use.

Tensile Strength and Elongation: Measures how much the film can be stretched before breaking. This is vital for vacuum sealing and high-pressure processing.

Heat Seal Strength: Since most food is sealed using heat, the standard defines how strong those seals must be to prevent leaks or contamination.

Puncture Resistance: A specific test where a needle is pressed into the film to determine the force required to pierce it, crucial for packaging bones, frozen foods, or sharp-edged snacks.

Impact Resistance: Measures the energy required to rupture the film under high-speed impact. 3. Sensory and Hygiene Standards

Because the film is in direct contact with food, JIS Z 1707 places heavy emphasis on the "neutrality" of the material.

Odour and Taste: The standard requires that the plastic does not impart any "off-flavours" or chemical scents to the food product.

Appearance: The film must be free of bubbles, pinholes, or foreign particles (like dust or un-melted resin) that could compromise the seal or aesthetics.

Extraction Tests: These tests involve soaking the film in "simulants" (like water, acid, or alcohol) to ensure that chemicals like heavy metals or evaporated residues stay below hazardous levels. 4. Importance for Laminated Films JIS Z 1707: The Standard for Food Packaging

Modern food packaging rarely uses a single type of plastic. Most are "laminates" (e.g., PET/PE or Nylon/CPP). JIS Z 1707 provides specific guidelines for:

Interlayer Bonding: Ensuring the different layers of plastic do not peel apart (delaminate) during the boiling, freezing, or retort (pressure cooking) process.

Solvent Residue: Ensuring that the adhesives used to stick the layers together have fully dried and do not contain toxic volatile organic compounds (VOCs). 5. Why It Matters for Global Trade

If you are an exporter looking to sell food products in Japan, your packaging must comply with JIS Z 1707. Even for companies not selling in Japan, following this standard is often seen as a mark of "premium quality" because its testing thresholds are frequently more stringent than general ISO standards.

9. Common Non-Conformities and How to Avoid Them

Based on factory audit data, the most frequent failures when testing to JIS Z 1707 are:

1. Inconsistent thickness – especially center-to-edge variation in blown films. Use automatic gauge control and die centering tools.
2. Low tear strength in TD – often due to poor MD/TD orientation balance. Adjust blow-up ratio (BUR) to 2.0–2.5 for LDPE.
3. COF outside range – too much slip additive (high COF) or insufficient corona treatment (low COF). Monitor additive dosing carefully.
4. Tensile elongation below 200% – excessive regrind or degraded resin. Limit regrind to ≤ 15% for Type 2 films.

11. How to Source JIS Z 1707 Compliant Films

If you are looking to purchase polyethylene film that meets JIS Z 1707, follow this checklist:

1. Request a certificate of compliance – Not just a claim, but a test report from an accredited lab.
2. Verify the type – Do you need general (Type 1), heavy-duty (Type 2), or special (Type 3)?
3. Ask about additives – Slip, antiblock, UV, or anti-static? Ensure they don’t violate JIS restrictions.
4. Check roll geometry – Core inner diameter (typically 76 mm or 152 mm), roll squaring, and telescoping limits.
5. Sample testing – Before bulk order, have 10 meters tested for tensile and tear strength at a third-party lab.

4.6 Coefficient of Friction (COF)

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

• Static COF: 0.3 – 0.6
