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

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 jis z 1707

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? Using a "dart drop" or pendulum method, this

Ensuring the plastic does not migrate harmful chemicals into food. Importance in Food Safety Established by the Japanese

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

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

This evaluates how well the film resists sharp objects. For products with hard edges (like dried pasta or electronic components), high puncture resistance is mandatory to maintain a vacuum or a sterile environment. 4. Impact Resistance
