The standard also covers dimensional tolerances and visual acceptance criteria:
JIS Z 1707 defines several mechanical and physical testing methods to ensure safety and quality throughout the food distribution chain:
Puncture strength is a critical property for food packaging films, as they must resist damage from sharp-edged contents such as bones, shells, or rigid product corners, as well as external protrusions during distribution. Insufficient puncture resistance can lead to pinholes, leaks, spoilage, and consumer complaints.
While it doesn't cover films made of paper or metal foils, it is the "gold standard" for evaluating modern flexible packaging like spout pouches and snack bags. Key Performance Tests jis z 1707

| Test Item | Key Parameters | Purpose | | :--- | :--- | :--- | | (耐熱温度試験) | Uses saturated brine solution inside a pouch; tested at various temperatures/times (e.g., 120°C/60s). | Determines the maximum temperature a film can withstand without deforming or delaminating. | | Coefficient of Friction (Static & Kinetic) (静摩擦係数及び動摩擦係数) | Measures resistance to sliding, typically film-to-film. | Essential for ensuring films run smoothly on high-speed packaging machinery. | | Haze Test (ヘーズ試験) | Performed with a haze meter, following methods like JIS K 7136. | Measures the clarity or cloudiness of a transparent film. | | Wet Tension Test (ぬれ張力試験) | Uses a series of test solutions with increasing surface tension. | Evaluates surface treatment for printability and adhesive lamination; often references JIS K 6768. | | Anti-fogging Property Test (防曇性試験) | Evaluates a film's ability to prevent condensation on its inner surface. | Crucial for fresh produce packaging to ensure product visibility. | | Shrinkage Test (収縮性試験) | Measures dimensional change when heat is applied. | Important for shrink-wrap films used for bundling or tamper evidence. | | Surface Roughness Test (表面粗さ試験) | Typically measures parameters as defined in JIS B 0601. | Affects print quality, coefficient of friction, and the optical properties of the film. |
