(MD = Machine Direction, TD = Transverse Direction)
Yuki framed a copy of JIS Z 1707. Not because standards are exciting — but because sometimes, , waiting for someone to read it.
: Conducted in accordance with JIS K 7124, a free-falling weighted dart calculates the physical energy threshold required to burst the film. This simulates stack drops and transportation vibrations. Environmental Barrier Performance
The standard applies specifically to plastic films used for food packaging. This includes single-layer films, laminated films (multi-layer), and coated films. It covers: jis z 1707
establishes the "General Rules of Plastic Films for Food Packaging," providing a standardized framework for the design and performance of plastic films used to protect food products. Scope and Application
). It excludes multi-layer configurations incorporating paper or metal foils.
JIS Z 1707 mandates that the polyethylene resin must be: (MD = Machine Direction, TD = Transverse Direction)
The standard enforces uniform testing methodologies to ensure films resist processing stress, survive distribution networks, and maintain a sterile seal.
Her boss said, “Just use thicker film.” But thicker meant more plastic, higher cost, more waste.
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: This simulates stack drops and transportation vibrations
Although JIS Z 1707 was last confirmed (with minor revisions) in the early 2000s, it remains widely used because:
The maximum stress a film can handle before breaking.
As of 2025, JIS Z 1707:2019 remains the current standard. While no revision has been announced, the packaging industry is constantly evolving. Key trends that may influence future revisions include:
JIS Z 1707 explicitly covers:
