Our product is ice and we use colour raffia string to tie our ice pack and use it as a identification of product batch. we got 2 size of packaging 1 is 18kg and antoher 1 is 2,5kg (this packaging is heat sealing and we will put 5 pack of 2.5kg packaging into 1 plastic bag and tied with raffia string)which we normally find in convient store. we have problem of product identificaion for 2.5 kg packaging when reach customer site.. as customer will take out 5 pack of 2.5kg packaging and displayee at their chiller and no identication product can be traced..
So anyone of you enounter such situation before or mind to sharing you opinion on issues above, thanks in advance.
