Allergen Ingredients in Food Packaging

Hello all,

Our packaging supplier notified us that the resin and  the colorant  that they use to manufacture the plastic lids for our products,  contain Soybean. 

I wonder what is the risk of allergen contamination for our finished product through the plastic lid?

This is the first time I hear that allergens are used as an ingredient in packaging manufacturing.

Thanks for your help! 

Actually, for production of cardboard packaging glue that is gluten based is used, so yes there is potential risk for cross contamination due to inadequate handling and improper separation. 

So, in your specific case, first question is plastic lid in direct contact with the product? If yes, there is higher risk of cross contamination

You can also check the presence of allergen in final packed product and do your own small study and validation. Send it to laboratory for test, and ask supplier do they have any estimated amount of potential allergen containing in lids. 

I hope this helped!

Hi Vladimir, 

Thank you for  your comment.

The lids are direct food contact, after the aluminum foil is removed.

I am trying to find what kind of soy ingredients they use and the actual amount of it in the lid. I found that refined soy oil is not considered as allergen. 

Let's hope that this is the case.

Thanks

I'm going to guess, this is no longer soy protein at this stage and therefore allergen free or it wouldn't be widely used  but you definitely need confirmation from the manufacturer

I would second this. My company uses soy based inks and have a statement from our supplier that the allergenic properties are no longer present after the processing used to produce the inks. I would think it would be similar and your supplier should be able to get a similar statement from their supplier.
