Tensile properties determine how a film behaves under pulling forces — a critical aspect for processes such as form‑fill‑seal (FFS), handling, and end‑use. While JIS Z 1707 references JIS K 7127 for the detailed tensile testing methodology, the standard itself includes specifications for sample preparation, test speed, and acceptance criteria.
JIS Z 1707, as of its latest revision, does require biodegradability. However, a study group within the JSA is evaluating:
JIS Z 1707’s specifies the heat seal strength test method: jis z 1707
is a critical Japanese Industrial Standard titled " General rules of plastic films for food packaging ". It establishes the foundational guidelines and testing protocols for plastic materials directly in contact with food. Scope & Purpose
The standard was notably updated to JIS Z 1707:2019, incorporating stricter safety requirements regarding substance migration, aligning with modern food safety regulations. Key Requirements of JIS Z 1707:2019 Tensile properties determine how a film behaves under
| | Typical Properties | Applications | |---|---|---| | Polyethylene (PE) | Flexible, moisture‑resistant, cost‑effective | Fresh produce bags, frozen food packaging, bread bags | | Polypropylene (PP) | Heat‑resistant, clarity, good barrier | Snack food wrappers, candy wrappers, heat‑sealable pouches | | Polyester (PET) | High tensile strength, excellent clarity, good gas barrier | Laminated structures, stand‑up pouches, high‑clarity applications | | Polyamide (Nylon) | Exceptional puncture resistance, good oxygen barrier | Vacuum packaging, cheese packaging, processed meats | | PVDC | Excellent gas and moisture barrier | High‑barrier applications, such as coffee, tea, and dried foods |

Understanding JIS Z 1707: The Standard for Food Packaging Plastic Films
In an age of globalization, where many manufacturers default to ISO standards, remains a gold standard for disciplined quality. Its strict requirements for tear strength, dimensional precision, and frictional properties make it the preferred specification for high-speed automated packaging lines, delicate component protection, and heavy-duty industrial logistics.
