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. jis z 1707

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

Recommendations for Stakeholders

• Designers/manufacturers: Integrate adjustable features into primary product lines; provide clear documentation on recommended set-up and target user anthropometrics.
• Employers/occupational health teams: Conduct baseline ergonomic assessments, supply adjustable equipment, and implement training and break policies.
• Regulators/policymakers: Harmonize JIS recommendations with occupational safety regulations and update guidance to reflect technological changes.
• Individuals: Adjust monitor height so top of screen is at or slightly below eye level, maintain 50–70 cm viewing distance (or a comfortable arm’s length), use task lighting to avoid glare, and take regular short breaks.

3.1 Resin Specifications

JIS Z 1707 mandates that the polyethylene resin must be: JIS Z 1707:2019 is the current Japanese Industrial

• Homopolymer or copolymer of ethylene
• Free from recycled or reclaimed material unless explicitly permitted by buyer-seller agreement
• Stabilized with approved antioxidants and UV inhibitors (for outdoor use)

2. Classification of Films

One of the distinct features of JIS Z 1707 is its classification system, which categorizes films based on their manufacturing process and density. This classification helps manufacturers select the right material for specific applications.

• Class 1 (Low-Density Polyethylene - LDPE): This is the most common type, characterized by high flexibility, transparency, and good heat-sealing properties. It is typically used for fresh produce, bakery items, and general food wrapping.
• Class 2 (High-Density Polyethylene - HDPE): This material is stiffer, stronger, and offers better moisture barrier properties than LDPE. It is often used for heavier items or where greater rigidity is required.
• Class 3 (Linear Low-Density Polyethylene - LLDPE): This type offers superior tensile strength and puncture resistance compared to standard LDPE, making it ideal for stretching applications and packaging sharp or irregularly shaped foods.

8.2 Marking Requirements

Certified rolls must be labeled with:

• “JIS Z 1707” clearly visible
• Type (1, 2, or 3)
• Nominal thickness (mm)
• Width (mm)
• Length (m)
• Manufacturer name or trademark

JIS Z 1707: The Standard for Food Packaging Films

In the global landscape of food safety and manufacturing, standards act as the universal language ensuring quality, consistency, and consumer protection. In Japan, one of the most critical standards governing the packaging industry is JIS Z 1707. [ ] Accept as is [ ] Accept

This standard, formally titled "Polyethylene film and sheet for food packaging," outlines the specific requirements, testing methods, and classifications for plastic films used to wrap and protect food products. As Japan is renowned for its rigorous food safety regulations and high-quality packaging technology, understanding JIS Z 1707 is essential for domestic manufacturers, international exporters, and packaging engineers.

Introduction: What is JIS Z 1707?

In the world of industrial packaging and material science, standards are the invisible backbone that ensures quality, safety, and interchangeability. One such critical standard, particularly within the Japanese industrial landscape and increasingly recognized globally, is JIS Z 1707.

JIS Z 1707 specifies the requirements for general purpose polyethylene (PE) films used for packaging and general industrial applications. This Japanese Industrial Standard (JIS) outlines the classification, quality, test methods, and dimensions of flexible polyethylene films not intended for agricultural use (which falls under a different standard, JIS K 6782).

If you are a manufacturer, quality control engineer, procurement specialist, or packaging designer working with polyethylene materials in regions that adhere to Japanese specifications (including automotive parts, electronics, food packaging, or heavy industry), understanding JIS Z 1707 is non-negotiable. This article provides a deep technical dive into every clause, test method, and practical implication of JIS Z 1707.

Heavy-duty liners (Type 2) are used for shipping bumpers, dashboards, and large injection-molded components. The high tear resistance prevents punctures from sharp edges.
