What is your risk in terms of allergens? I have to think if you just produce packaging the only risk would be foods brought in by employees to consume during break. If that's the case your program should be fairly easy to lay out. Explain how you would control them storing and consuming their food (isolate it to break rooms). How do you mitigate risk (they wash their hands following proper handwashing procedures before coming back to the floor). Also have a plan in place and documented in case there is an incidental contamination of allergens (such as you receive pallets and find peanut shells on them, etc.). How will you train staff on allergen control and finally what allergens are of concern and should you be aware of (where all do you ship your product, if in US and Canada, you need to be aware of both US and Canada's allergens). These are things to lay out as part of your allergen control program. If you do not use or store allergens at your site, then your control program should be fairly simple to lay out.
