There has been a gradual change in the mode of packaging for last years.For instance, earlier fruits and vegetables were used to be transported in wooden boxes but today cardboard crates are used .This is mainly to reduce the cost. Obviously,a cardboard crate would cost less than wooden crate. Moreover,using cardboard crates is more eco friendly than cutting trees and making wooden boxes and supporting an environmental cause helps firms improve their goodwill and eventually their sales.
Similarly,selling of milk,first in glass bottles,then in packets ,then tetra packs and vending machines is all to reduce costs or improve their goodwill by innovating the mode of packaging. Tetra pack keeps the milk safe for months and is made of paper and can be recycled. Plastic packets incur lesser costs and vending machines in itself have no packaging cost.
So,companies use new and unique mode of packaging to ,one,reduce their costs,two,to promote the product.
