Well, there are multi vendors policy by ecommerce giants since any 1 or 2 supplier can’t supply entire requirements.
Most of the arrangements are done based on geographical location of amazon and supplier's location.
For Example- Suppliers located in Ahmedabad will deliver material to Amazon warehouse in West India.

 

Amazon purchases packaging material and consume the same for all orders that are packed from amazon warehouses. 
Sellers are supposed to give product in primary packaging with adequate labeling as required.
Once the order is received, amazon picks the product, pack the same and dispatch to customer.
Amazon charges pick and pack fees to the seller.

Also packaging material for ecommerce has so many variants. Some of the main packaging material used by ecommerce in India.

2.       Corrugated Boxes

3.       Cello Tapes/Adhesive Tapes
