Packing Material Purchase Expense Record

I need to purchase packing material for my shop. I want to record it as an expense that should be deducted from my cash or bank account. How to do it?
Thanks in Advanced

You can use Payment for cash purchases

If you do record your packing material as inventory, then you just record the cash payment and charge it to an appropriate expense account such as packing materials

I presume that you do not charge your customers for the packing material
