Not fixed, but typical lengths are 500 m, 1000 m, or 1500 m, subject to thickness and width parameters.
JIS Z 1707 is the foundational standard for plastic films used in food packaging in Japan. It defines the classification, physical and mechanical properties, barrier performance, hygienic safety, and testing methods that ensure these films are fit for their intended purpose. Whether you are a film manufacturer, a food packager, a quality control professional, or a regulatory specialist, a thorough understanding of JIS Z 1707 is essential for ensuring product safety, regulatory compliance, and market acceptance. Precise measurement is required, often using equipment like
