Choosing suitable environmentally friendly food packaging paper requires a comprehensive consideration of safety indicators, type characteristics, and performance. Prioritize compliance with GB 4806.8-2022 standard, and match core properties such as waterproofing, oil resistance, and biodegradability according to the intended use.
Primary Safety Indicator: Ensuring Compliance and Avoiding Health Risks
Safety is the bottom line when choosing environmentally friendly food packaging paper. It must meet the national mandatory standard GB 4806.8-2022 "National Food Safety Standard - Paper and Paperboard Materials and Products for Food Contact," focusing on the following five key indicators:
Heavy Metal Content:
Lead (Pb) ≤ 5.0 mg/kg, Arsenic (As) ≤ 1.0 mg/kg. Exceeding these limits may cause chronic poisoning.
Fluorescent Substances:
Not detectable under 254nm and 365nm ultraviolet light to prevent the migration of fluorescent whitening agents into food.
Microbial Control
Coliform bacteria ≤ 30 CFU/100g; pathogenic bacteria (such as Salmonella, Staphylococcus aureus) must not be detected.
Formaldehyde and Chloropropanol Residue
Formaldehyde must not be detected; newly added indicators: 1,3-dichloro-2-propanol must not be detected; 3-chloro-1,2-propanediol ≤ 12 μg/L, to control the chemical risks posed by wet strength agents.
Negative Decolorization Test
Does not lose color after contact with water or oil, preventing dye contamination of food.
