Jis Z 1707
Here is a feature breakdown of JIS Z 1707, highlighting why it is a critical benchmark for food safety and packaging performance.
Sharp food items (such as bones, dried noodles, or hard shells) can easily pierce weak packaging. JIS Z 1707 specifies a needle puncture test to measure the material's resistance to sharp objects, ensuring the barrier remains unbroken during transit. 4. Hygiene and Migration Standards
: Stipulates minimum and maximum allowable values; for instance, some classes require values jis z 1707
: Heat resistance is classified into six levels based on temperature/time combinations: 120°C/60 seconds, 110°C/60 seconds, 100°C/60 seconds, 100°C/30 seconds, 90°C/30 seconds, and 70°C/30 seconds. A film’s heat resistance is determined by subjecting a sealed pouch containing a saturated sodium chloride solution at 40°C to the specified temperature and time, then inspecting for deformation, delamination, or seal peeling.
One of the strongest features of the standard is how it strictly categorizes films based on their chemical composition. This helps manufacturers and consumers choose the right film for the right application (e.g., microwave safety vs. freezer storage). Here is a feature breakdown of JIS Z
Last reviewed: Based on JIS Z 1707:2003 (latest confirmed version). Always check the latest revision from the Japanese Standards Association (JSA) for amendments.
The heat seal strength is typically expressed as force per unit width, such as or N/15 mm width . One of the strongest features of the standard
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
