Humans began packaging products over 3,500 years ago in Egypt. This early on their sole purpose was for transporting food and beverages. They were made of natural products, like leaves, animal skins, or coconut husks. With time this developed and the Egyptians started using glass containers in 1500 BC. It wasn’t until Napoleon in the early 1800’s when tin cans were finally developed. From then packaging development began to speed up with the invention of paper bags in 1850, cartons in the 1870’s, cardboard containers in 1906, cans in 1935, and plastic containers in the late 1940’s. In the early days containers were mostly unbranded, designed solely for functionality, and lacked aesthetic appeal.
