: Measures the maximum stress the film can withstand while being stretched. Standard values often required for edible packaging are around
In the world of food safety and packaging reliability, standards play an essential role in ensuring that the materials contacting our food are consistent, safe, and fit for purpose. Among these, stands as a cornerstone Japanese Industrial Standard (JIS) for plastic films used in food packaging. Whether you are a packaging engineer, quality assurance professional, manufacturer, or importer, understanding JIS Z 1707 is crucial for ensuring product safety and compliance across Japan and beyond.
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.
The standard restricts the presence of heavy metals like lead, cadmium, and mercury, which can be present in inferior plasticizers or colorants.
Measures how much the film can be stretched before breaking. This is vital for vacuum sealing and high-pressure processing. jis z 1707
JIS Z 1707 is formally titled . This standard specifies the general matters common to single‑layer plastic films and multi‑layer plastic films (hereafter referred to as “films”) that are used for food packaging.
A distinct feature of JIS Z 1707 is that it does not treat all films the same regarding strength. It divides them into and Type 2 based on mechanical properties:
Users of JIS Z 1707 should periodically check the Japanese Standards Association website (webdesk.jsa.or.jp) for updates, revision announcements, or reaffirmation notices.
This standard does not apply to multi-layer plastic films consisting of paper or metal foils. : Measures the maximum stress the film can
The standard applies to low-density polyethylene (LDPE), linear low-density polyethylene (LLDPE), and high-density polyethylene (HDPE) films.
[e.g., JIS Z 1707 draft lacks high-temperature performance criteria found in ISO.]
The "teeth" of JIS Z 1707 lie in its specific testing protocols. To comply with this standard, a plastic film must be vetted through several mechanical tests: 1. Tensile Strength and Elongation
: For this standard, "films" are high-polymer membranous materials with a thickness less than 250 µm . Whether you are a packaging engineer, quality assurance
While many international standards exist, JIS Z 1707 is specifically respected globally for its rigorous testing methods and strict adherence to hygiene and performance metrics. 1. Scope and Application
JIS Z 1707 does not exist in isolation. It is part of a larger ecosystem of Japanese (JIS) and international standards. The standard several other JIS documents, meaning compliance with these references is mandatory for full compliance with JIS Z 1707. Key among these are standards for test methodologies, such as:
The history of JIS Z 1707 reflects the evolution of plastic packaging technology and food safety requirements. The standard was first established on . Over the decades, it has been revised several times to keep pace with advancements in materials science, testing methods, and regulatory expectations.
Measures the energy required to rupture the film under high-speed impact. 3. Sensory and Hygiene Standards
