Inventory: what about packaging materials and logo stickers?

I bake biscuits as a secondary occupation. Do I have to include the bags I put the biscuits in with my closing inventory for the financial year? These are not charged for or sold separately, but the customer does receive them… The same applies to the (logo) stickers that go on the bags… Are these trade goods, or advertising/marketing, small expenses of various kinds, etc.?

Thank you for your insights 🙂
