: By outlining precise engineering tolerances and testing methodologies, the document establishes a shared technical language between polymer suppliers, converters, and food manufacturing QA teams. Critical Material Specifications and Tolerances
Compliance with is impossible without proper testing. The standard references the following JIS test methods (most align with ISO or ASTM equivalents but have unique acceptance criteria). jis z 1707
The "best feature" of JIS Z 1707 is its balance between . It provides a universal language for the industry: : By outlining precise engineering tolerances and testing
Heavy-duty liners (Type 2) are used for shipping bumpers, dashboards, and large injection-molded components. The high tear resistance prevents punctures from sharp edges. The "best feature" of JIS Z 1707 is its balance between
| Parameter | JIS Z 1707 (Japan) | ASTM D2103 (USA) | ISO 11248 (International) | |-----------|---------------------|------------------|----------------------------| | Tensile strength requirement | Higher (≥ 19.6 MPa) | Lower (≥ 13.8 MPa typical) | Moderate (≥ 16 MPa) | | Tear strength | Mandatory for heavy-duty | Not always tested | Optional | | COF specification | Strict range | Not specified | Not specified | | Thickness tolerance | Tighter (±7-10%) | Looser (±15% typical) | Moderate (±12%) |
By defining strict testing methodologies and performance thresholds, the standard protects consumers from chemical contamination and ensures that packaging can withstand the rigors of thermal processing, transportation, and storage. Key Testing Parameters and Requirements
The film must be strong enough to withstand the rigors of packaging machinery and transportation. The standard defines minimum tensile strength (force required to break the film) and elongation (how much the film can stretch before breaking).
