Regarding food-grade self-adhesive plastic bags (plastic bags self adhesive), to meet the standards for food packaging, the following conditions are required:
1. Use food-grade raw materials
The plastic itself (such as OPP, PE, CPP, PET, etc.) must be food-grade, that is, the raw materials have passed the food contact safety certification before production.
No harmful additives, such as heavy metals, plasticizers, etc., may be added.
2. Glue/self-adhesive must also be food-grade
The glue used in the self-adhesive part must be food-contact grade glue developed specifically for food contact.
The glue cannot release harmful substances and must not migrate into food under normal use conditions.
3. Compliance with food safety regulations and certification
It is necessary to comply with international or regional food safety regulations, such as:
US FDA standards (21 CFR 177.1520 and other clauses)
EU 10/2011 Food Contact Plastics Regulations
China GB 4806 series standards (such as GB 4806.7-2016 Plastic Materials and Products)
Sometimes customers will also require SGS test reports, LFGB certification, etc. to confirm the safety of the product.
4. The factory production environment must meet the standards
The production environment must meet the requirements of dust-free and non-toxic, and it is best to have ISO 22000 Food Safety Management System Certification or similar certification.
There should be no secondary pollution during the production process, especially the gluing and compounding links must be strictly controlled.
5. Migration test (if necessary)
It is necessary to pass the overall migration amount (OML) and specific migration amount (SML) tests to ensure that the packaging material will not migrate harmful ingredients into the food.
Food grade self-adhesive plastic bags = food grade raw materials + food grade glue + in compliance with international food safety certification + the production process meets food packaging requirements.
