Woven Packaging Meeting Japan's Positive List Standards: A Significant Step Forward for Green Packaging
Japan is known as one of the world's most stringent markets for food packaging and contact materials. Overcoming the "technical barriers" in this market is the strongest affirmation of a manufacturer's credibility. Recently, Green Packaging Joint Stock Company proudly announced that its food packaging line has successfully met Japan's Positive List standards, opening doors for official exports to the land of cherry blossoms.
1. JFRL Certification: The Prestigious Passport for Food Packaging
On June 11, 2026, the Japan Food Research Laboratories (JFRL) — the leading testing agency authorized by the Japanese Ministry of Health, Labour and Welfare — officially issued certificate No. 26056570001-0101 for the Woven PP product (Model: E500) manufactured by Green Packaging.

The results from JFRL are the most objective proof that Green Packaging's entire technological process, raw materials, and plastic additives perfectly meet the strictest control standards for food-contact packaging at temperatures up to 100°C.
2. Understanding Japan's "Positive List" Standard
The Positive List system clearly stipulates: Only substances, base materials, and additives that have been tested, evaluated for safety, and published on the official list by Japanese authorities are permitted for use in the production of food packaging materials.
Any substance not included on this list is considered non-compliant and completely prohibited from import. This technical barrier requires manufacturers to master their entire supply chain, ensure 100% purity of raw materials, and prevent any chemical contamination during production.
3. Detailed Test Results for Product Code E500
According to the report from the Japanese inspection bureau based on Japan's Ministry of Health Notification No. 370, Green Packaging's "PP tube fabric (Model: E500)" sample demonstrated absolute biological safety metrics:
