Z 1707 — Jis

It serves as the foundational regulatory framework for ensuring the quality and safety of plastic films used in the food industry. 日本規格協会 JSA GROUP Webdesk Overview of JIS Z 1707 The standard specifies general requirements common to both single-layer multi-layer

: Covers single-layer and multi-layer plastic films with a thickness of less than 250 µm .

: Defines requirements for measurement tools, such as dial gauges and calipers, to ensure consistent film thickness and texture. Intertek Inform Industry Significance jis z 1707

Compliance with JIS Z 1707 is a critical benchmark for manufacturers producing biodegradable, edible, or synthetic films, as it ensures they meet specific performance thresholds for commercial use.

If you are exporting to Japan, JIS Z 1707 is for many packaging applications. Using an equivalent foreign standard may lead to rejection by Japanese customs or downstream factories. It serves as the foundational regulatory framework for

The standard mandates strict control over average thickness and local deviations. For example:

The film must be strong enough to withstand the packaging process and consumer handling but flexible enough to conform to the product. Intertek Inform Industry Significance Compliance with JIS Z

The standard specifically covers:

: Applies to high-polymer membranous materials used as food wrapping or components for bags and containers. : It specifically covers films with a thickness of less than 250 µm Exclusions

JIS Z 1707 allows for the use of recycled polyethylene, provided the final film meets all mechanical and visual requirements. However, the standard strictly regulates for substances that could contact food (although food packaging is secondary in this standard).

The standard broadly categorizes films based on their physical form and intended usage:
