The notification sets out a quality standard for plastic food containers. In addition, the notification lifted a ban on using recycled materials for food containers to promote the circular economy of the Kingdom. The notification has been effective since 18 June 2022 and the previous Notification (No. 295) B.E. 2548 (2005) on the Determination of Quality or Standards of Plastic Containers, dated 30 December 2005, was repealed.
Definition of recycled plastic food container
In the notification, “Container made from recycled plastic” is defined as a container made from recycled plastic which has a recycling process as follows:
- Primary recycling: pre-consumer scrap means the in-house processing of plastic parts or scrap which is left over from the food container manufacturing process to be recycled by parts. Such plastic or plastic scraps must have never been in contact with food before.
- Secondary recycling: physical reprocessing mechanical recycling means the physical processing of plastic food containers, including mechanical methods such as grinding, washing, and chemically treating the plastic and then melting it into plastic pellets to be used as containers. However, these processes must not alter the structure of the polymer.
- Tertiary recycling: chemical reprocessing means the processing of plastic containers that have been used to contain food back to their original form by using chemical processes.
