Coating inside the carton for plastic bottle
Hello,
We plan to add a layer of coating inside the carton, and put the bottles in the carton without polybag.
Does the coating have to be food grade?
Thanks,
Nathan
This carton is just secondary packaging with no product contact? The sort of paperboard container a dozen plastic bottles of product with be held inside for retail sale as one item?
are the bottles open? is this a packaging product or a food product?
The coating inside the carton will contact the outside of the bottles. There are 6 bottles in the carton.
When the retailer receives them, they will take the bottles out of carton and sell them individually.

The bottle is closed with lid, but there is valve inside of the lid.
We are concerned whether the chemical of coating can migrate to the valve.
