Testing to ensure the film doesn’t impart an "off" taste or smell to the contents.
Established by the Japanese Industrial Standards Committee, JIS Z 1707 specifies the requirements for plastic films used specifically for general packaging. Here is a comprehensive look at what this standard entails and why it matters. What is JIS Z 1707? jis z 1707
In the world of packaging engineering, reliability isn’t just a preference—it’s a requirement. Whether you are protecting food, electronics, or medical devices, the integrity of the plastic film used is governed by rigorous standards. One of the most critical benchmarks in this industry is . Testing to ensure the film doesn’t impart an
For films used in shrink-wrapping, JIS Z 1707 provides guidelines on how much the material should contract when heat is applied, ensuring a snug, professional fit. Importance in Food Safety What is JIS Z 1707
Perhaps the most vital test for food safety. This measures the force required to pull apart a heat-sealed seam. If the seal strength is too low, the package may leak or become contaminated; if it's too high, the consumer may find it impossible to open. 3. Puncture Resistance
Using a "dart drop" or pendulum method, this test determines the film’s ability to absorb energy during a sudden impact, simulating a package being dropped. 5. Shrinkage Factor
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
