Food Contact Material Testing Certification In Japan By JFSL370

Product Specification

Japanese food contact material testing
Basic introduction
The Japanese food contact material testing regulations are controlled by the Ministry of Health, Labor and Welfare of Japan, Japan Food Sanitation Law 370 (Japan Food Sanitation Law 370), referred to as JFSL370.

The control scope of Japanese food material contact test JFSL370 mainly includes metal, glass, rubber, ceramics, plastics, paper, silicone, organic coatings, wood, etc. Among them, there are 13 kinds of plastics such as PVC, PE, PP, PS, PVDC, PET, PMMA, PC, PVOH, etc. Different materials have different test items.

Common materials for Japanese food contact materials are:
LWA 370's control scope for food-grade materials mainly includes rubber, metal, glass, ceramics, enamel glaze, plastics, paper, organic coatings, and wood. Japan JFSL370 has different test items for different test materials.
