Jis Z 1707 outlines several key components that are essential for ensuring the quality and safety of compressed air. These components include:
Compliance can be demonstrated through:
is the Japanese Industrial Standard that outlines the "General rules of plastic films for food packaging." Established by the Japanese Standards Association (JSA) and the Japan Packaging Institute (JPI), it serves as a foundational benchmark for testing and qualifying single-layer and multi-layer plastic packaging materials intended for food products.
JIS Z 1707 applies strictly to membranes mostly composed of polymer materials designed for food containment.
JIS Z 1707 outlines precise testing protocols to evaluate how packaging performs during factory sealing, shipping, and handling: 1. Puncture Strength Test
: Determines the stiffness of the material, requiring a standard minimum of ≥ 0.35 MPa to maintain shape. 2. Puncture Resistance (The Puncture Test)
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 with is impossible without proper testing. The standard references the following JIS test methods (most align with ISO or ASTM equivalents but have unique acceptance criteria).
“Everyone ignores this,” her senior muttered. “Too picky.”
Most automated distribution pouch failures stem from structural weakness at the thermal weld zone. This metric evaluates the force threshold required to split the fused layers under uniform tension. 3. Piercing and Impact Resistance
The current active edition is , which supersedes the 1997 edition. Key tests include puncture strength (with a 1.0 mm needle at 50 mm/min), tensile strength, heat seal strength, water vapor transmission rate, and oxygen transmission rate. Compliance with this standard, together with Japan’s Food Sanitation Act, ensures that plastic films are safe, reliable, and perform as expected throughout the food supply chain.
