Packing and packaging serve several important functions including protecting products from damage, leakage, evaporation and theft. It also provides convenience for customers and attractiveness on shelves. Effective packaging identifies products, projects quality and allows for self-service. There are different levels of packaging for industrial, consumer and reusable/multiple packages. Packaging materials and formats are chosen based on the type and level of product. While packaging benefits customers and sales, it can also cause issues if it is deceptive, inflates contents or poses health hazards. Sustainable solutions include reusable containers and proper waste disposal. Product positioning creates an image in customers' minds by differentiating products, indicating key benefits and articulating brand characteristics to maintain priority.
