What Is a Food-Grade PE Bottle?
A food-grade PE bottle is made from resins certified for food contact use, produced in a clean environment, and tested to ensure safety. These bottles should not release harmful substances into the food and must comply with national or international food contact regulations.
5 Key Requirements for Food-Grade PE Bottles
1. Use of Food-Grade Resin
Must be made with HDPE or LDPE, certified by the FDA, or comply with GB 4806.6 in China.
The resin should be free of plasticizers or other additives that may migrate into food.
2. Non-toxic and Odorless Material
The material must be odorless and free of heavy metals or fluorescent agents to avoid affecting food quality or safety.
3. Compliance with Food Contact Safety Tests
Should pass migration tests, including overall and specific migration.
Must meet standards for infrared spectroscopy, microbial presence, and heavy metal release.
4. Hygienic Production Environment
Manufacturing should take place in a Class 100,000 cleanroom.
Proper control of dust, microbes, and particulates is necessary to avoid secondary contamination.
5. Clean Packaging and Dust-Free Handling
