This is a critical chemical test. The film is immersed in solvents (simulating different types of food—e.g., water for aqueous foods, heptane/ethanol for fatty foods) for a set period. The amount of chemical substances that "migrate" from the film into the solvent is measured. This must remain well below the safety threshold to prevent toxicity.
The films must meet minimum strength requirements to ensure they do not tear during packaging or transport:
JIS Z 1707 is a Japanese Industrial Standard (JIS) related to ergonomics and human factors in product design, specifically addressing visual display terminal (VDT) workstations and the visual environment. It situates itself within a broader set of standards intended to ensure safety, comfort, productivity, and health for users interacting with visual displays. This essay examines the standard’s scope, historical context, core requirements, technical rationale, practical implications for designers and employers, and its relationship to other national and international standards.
). It excludes multi-layer configurations incorporating paper or metal foils. jis z 1707
Unlike some Western standards that treat PE film as a single category, JIS Z 1707 introduces a classification system based on . The standard defines three main types:
: It explicitly does not apply to multi-layer structures containing paper sheets or metal foils (such as aluminium laminate layers). These materials are regulated under distinct material-specific standard groups. Crucial Material Requirements
The scope of Jis Z 1707 covers compressed air that is used for various purposes, including: This is a critical chemical test
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:
: A critical barrier property. For example, standards mentioned in literature indicate that high-quality edible films should not exceed a transmission rate of per 24 hours.
. This Japanese Industrial Standard is a critical benchmark for the quality and safety of plastic films used in food packaging. What is JIS Z 1707? JIS Z 1707:2019 (the most recent version) outlines the "General rules of plastic films for food packaging" This must remain well below the safety threshold
: Evaluates the material's elasticity and ability to deform before failing.
Limits on the residue remaining after volatile components evaporate from the film, tested in water, acetic acid, and alcohol solutions. 2. Physical Properties (Performance)
Measures the energy required to rupture the film under high-speed impact. 3. Sensory and Hygiene Standards
