: Evaluated under JIS K 7127 , which defines test conditions for the tensile properties of plastic films.
JIS Z 1707 categorizes films into types based on primary mechanical performance, not chemical composition. Common classes include:
These tests involve soaking the film in "simulants" (like water, acid, or alcohol) to ensure that chemicals like heavy metals or evaporated residues stay below hazardous levels. 4. Importance for Laminated Films
Ensuring that the adhesives used to stick the layers together have fully dried and do not contain toxic volatile organic compounds (VOCs). 5. Why It Matters for Global Trade
JIS Z 1707 sets mandatory tests for the following properties:
JIS Z 1707 includes performance grading systems for key properties, such as oxygen permeability and heat resistance. For example:
JIS Z 1707 defines several mechanical and physical testing methods to ensure safety and quality throughout the food distribution chain:
As the industry moves toward sustainability, is increasingly used to validate new, eco-friendly materials. Research studies (e.g., studies on carrageenan-based films or cassava starch mixtures) often use this standard to prove that new bioplastics are strong enough and safe enough to replace traditional plastic packaging, with many biodegradable formulations being designed to meet or exceed these traditional standards. Conclusion
JIS Z 1707 outlines precise testing protocols to evaluate how packaging performs during factory sealing, shipping, and handling: 1. Puncture Strength Test
Display characteristics
— A Chinese technical platform that provides access to JIS Z 1707:2019 and the superseded 1997 edition.
As per its official scope, JIS Z 1707 specifies the general matters common to and multi-layer plastic films (referred to collectively as "films") that are used for food packaging.
To qualify as a compliant food packaging material under JIS Z 1707, a plastic film must adhere to exact physical thresholds. In academic research and industrial cross-validation, the most frequently cited baselines include: Maximum Film Thickness
The increase in length of the film before breaking.
