How to set up PrestaShop to automatically add packaging to orders?

Question

Electronic commerce

As practice has shown, for sending parcels from an electronic store by international mail, especially in the case of sending fragile goods, you have to pack it in a fairly strong box and cram a decent amount of shock-absorbing materials (foam chips and pimply polyethylene), as a result of which the total mass of the parcel often exceeds the border of the next kilogram , moving to the next price category (which, when shipped from abroad to Russia, is quite noticeable money), and these materials themselves cost some money.
Accordingly, I would like to set up PrestaShop so that it is immediately added to the order and at least the gross weight (based on which the delivery price is calculated) is immediately calculated taking into account the packaging of the parcel, but it is better to add a little to the price. the old stocks of all this junk (accumulated from your own purchases) are running out and you will soon have to buy it (and the margins on goods are minimal), but a price premium can only be made if all this can be hung on postal delivery and excluded from pickup.
In principle, it logically looks like just another product that must be forced to be added to each order in the singular (it should not be possible to remove or accidentally increase the quantity).
Actually the question is how to achieve this.
Thanks in advance.
