This measures how much pull a film can withstand before it breaks. It ensures that the packaging won't snap under the weight of the product or during high-speed automated filling. 2. Heat Seal Strength

establishes the "General Rules of Plastic Films for Food Packaging," providing a standardized framework for the design and performance of plastic films used to protect food products. Scope and Application

To guarantee that a plastic film can withstand the stresses of automated filling, shipping, and storage while protecting the food inside, JIS Z 1707 mandates strict limits and testing procedures. 1. Mechanical and Tensile Properties jis z 1707

JIS Z 1707 classifies plastic films based on a number of criteria. This classification system helps manufacturers and users select the appropriate film for a given food application. Key classification factors include:

Compliance can be demonstrated through:

where a pin is pierced through the film to ensure sharp food edges (like bones or dried noodles) won't cause leaks. Barrier Properties: This article is for informational purposes only and

Here is a feature breakdown of JIS Z 1707, highlighting why it is a critical benchmark for food safety and packaging performance.

It serves as a critical reference for quality control managers, packaging engineers, and anyone involved in the manufacturing, selection, or regulation of plastic films for food applications.

JIS Z 1707 serves as the backbone of quality control for polyethylene food packaging in Japan. It bridges the gap between raw chemical engineering and consumer safety. For manufacturers, adherence to this standard is not just about regulatory compliance; it is a commitment to product integrity. It ensures that the packaging won't snap under

: The standard specifically excludes multi-layer packaging films that incorporate paper or metal foils (such as aluminum layers), which are governed by alternative standards. Key Performance Testing Metrics

JIS Z 1707 covers low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), and blends thereof. The films are typically used for:

The standard sets criteria for the . A good food packaging film must prevent moisture from entering or leaving the package, with many applications requiring a low WVTR (often cited around or below 168 g/m²/24h for certain applications) to ensure food stability. Importance of JIS Z 1707 in the Food Industry Compliance with JIS Z 1707 is critical for:
