We are at a meat processing factory (mortadellas, luncheons,..).
We use plastic containers which contain weighed quantities of spices and additives during our processing.
How to label these containers in a hygienic way? (the label must contain the name of the material inside and the quantity mainly).
Knowing that these containers are reusable (sanitized after each use), and paper stickers could not be easily removed properly and may attract bacterial growth.
I hope you could help..
