If I drop ship, will the packaging details will be from my supplier? I am afraid if I place an order with my supplier, then my customer get details of my supplier such as the price and the website.
No, it will be sent blind. Meaning no supplier details at all and the invoice will be sent direct to you. So as far as your customer is concerned, you're the supplier.
That's what dropshipping is, that's what dropshippers do. they send the item to your customer, but they send the invoice to you. So then it's up you to send your own invoice to your customer.
