In Odoo, you have the possibility to deliver your products in different packages, depending on the volume and or weight of your products.
First, you need to activate the Delivery Packages feature in the Inventory app --> Configuration --> Settings.

Now, you can create a planned delivery with some products in it. You will have the possibility to create new packages and assign them to the stock move lines.
Then, you can define the package type from this window. Once the delivery order is validated, you can retrieve which products have been included in the package.
A button will appear at the delivery stage, allowing you to find all the packages which were part of the delivery order.
