Jis Z 1707 Review

: Heat resistance is classified into six levels based on temperature/time combinations: 120°C/60 seconds, 110°C/60 seconds, 100°C/60 seconds, 100°C/30 seconds, 90°C/30 seconds, and 70°C/30 seconds. A film’s heat resistance is determined by subjecting a sealed pouch containing a saturated sodium chloride solution at 40°C to the specified temperature and time, then inspecting for deformation, delamination, or seal peeling.

: Stipulates minimum and maximum allowable values; for instance, some classes require values

: Covers single-layer and multi-layer films mainly composed of high-polymer materials.

JIS Z 1707 aims to provide guidance and specifications for designing VDT workstations and the surrounding visual environment so as to: jis z 1707

This is the most substantial section of the standard, providing the procedures for evaluating a film's performance. A summary of the key tests from the 2019 edition includes:

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.

: References standards like JIS B 7507 for measuring equipment (callipers) used to verify physical specifications. History and Context : Heat resistance is classified into six levels

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).

Compliance with Jis Z 1707 is essential for industries that rely on compressed air systems, such as:

JIS Z 1707, as of its latest revision, does require biodegradability. However, a study group within the JSA is evaluating: JIS Z 1707 aims to provide guidance and

For films used in shrink-wrapping, JIS Z 1707 provides guidelines on how much the material should contract when heat is applied, ensuring a snug, professional fit. Importance in Food Safety

It guarantees the film can handle the rigors of distribution, such as sealing, freezing, or vacuum packing. Application in New Materials (Biodegradable Plastics)

The maximum stress a film can handle before breaking.
