We do not have any set specifications for cardboard cartons used for transporting our packed food items like packed cereals. So every time we get a new sample of cardboard box from a carton supplier I am not sure how to verify the sample. What would be the most basic inspection tests or methods to verify the quality of the carton sample? We do not have an in house lab neither can I find a lab that does testing of cartons.
To verify the GSM, stacking strength and durability - what are some methods that can be done manually without testing instruments. Kindly advise. Thanks.
