The film must possess enough mechanical strength to withstand handling and transport. For example, some bioplastics aim for a tensile strength of at least to meet specific requirements within the standard. Thickness Uniformity:

. It applies to both single-layer and multi-layer plastic films—specifically those with a thickness of less than jis z 1707

The "test methods" section is the heart of JIS Z 1707. It ensures that all performance claims are verifiable through standardized procedures. The following are many of the tests specified in the standard.

The 2019 edition of JIS Z 1707 is systematically organized to guide manufacturers and users through the key aspects of film quality and performance. Its table of contents reveals a thorough and logical structure. The film must possess enough mechanical strength to

: It explicitly does not apply to multi-layer packaging webs that incorporate paper substrates or metal foils (such as aluminum barriers), which fall under separate material-specific JIS designations.

JIS Z 1707 is the that defines the "General rules of plastic films for food packaging". It outlines safety and quality standards for materials used to package food, ensuring that films do not contaminate food or affect its quality.

The most crucial aspect of the standard is ensuring that no harmful substances leach from the packaging into the food. JIS Z 1707 sets strict limits on the migration of chemical constituents, such as antioxidants or other additives, ensuring the material is suitable for direct food contact. 2.

Furthermore, JIS Z 1707 is part of a series of specific packaging film standards, such as for polyethylene films, JIS Z 1712 for oriented polypropylene films, and JIS Z 1715 for biaxially oriented PET films. It is also frequently used alongside general testing standards like JIS K 7127 for tensile properties and JIS Z 0237 for pressure-sensitive adhesive tapes.
