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
Ensuring the plastic does not migrate harmful chemicals into food.
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 . 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
Testing to ensure the film doesn’t impart an "off" taste or smell to the contents. This evaluates how well the film resists sharp objects
JIS Z 1707, titled "General rules of plastic films for food packaging," provides a framework for evaluating the physical and chemical properties of plastic films. While the title often emphasizes food packaging, the testing methods and quality benchmarks it sets are widely adopted across various industries to ensure film durability and safety.
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 Impact Resistance Ensuring the plastic does not migrate
Setting benchmarks for clarity, which is essential for consumer inspection of food products.
