JIS Z 1707:2019 General rules of plastic films for food packaging
To guarantee that a plastic film can withstand the stresses of automated filling, shipping, and storage while protecting the food inside, JIS Z 1707 mandates strict limits and testing procedures. 1. Mechanical and Tensile Properties
: The content of JIS Z 1707 could relate to various aspects of packaging, such as:

Understanding JIS Z 1707: The Standard for General Packaging Plastic Films
The primary objective of JIS Z 1707 is to standardize the physical, mechanical, and hygiene properties of plastic films and sheets intended for direct contact with food. It applies to single-layer films, multi-layer co-extruded films, and laminated materials. JIS Z 1707:2019 General rules of plastic films
Ensuring the different layers of plastic do not peel apart (delaminate) during the boiling, freezing, or retort (pressure cooking) process.
JIS Z 1707 remains a vital standard in the food packaging industry, guaranteeing that polyethylene films are safe for consumption-related uses. Furthermore, as the world moves toward sustainable packaging, JIS Z 1707 serves as an essential, rigorous benchmark for developing new biodegradable and bio-based films, ensuring that "green" solutions are also safe and durable.
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. with other international standards like FDA or EU
Thickness tolerances are strictly enforced, typically within ±10% of nominal value.
The standard often serves as a normative benchmark for compliance audits, procurement specs, and corporate ergonomics policies.
The standard dictates strict parameter thresholds to verify that flexible barriers are strong enough to protect shelf-stable and fresh products. It covers dimensions, physical performance, and moisture control.
Measures the energy required to rupture the film under high-speed impact. 3. Sensory and Hygiene Standards
