It can include three types of packaging: a) primary, b) secondary and c) distribution (shipping) package. Some authors also determine other types of packaging: d) convenience packaging, e) wasteful packaging
Primary packaging refers to the materials that are in immediate contact with the final product as well as all the packaging that surrounds it when the consumer buys it; in other words, it is the first packaging layer in which the product is contained
As such, primary packaging is constructed both with the product itself and any existing secondary layers of packaging in mind.
This is the first layer containing the finished product, such as a plastic pouch holding whole-grain cereal or the cardboard box containing the pouch of cereal. This type of packaging is often intended for the end user or consumer.
Primary packaging can have diverse applications and functions, depending on the product, and transit and storage variables. The most obvious, and important, function is to protect and preserve the product from damage, external interference or contamination, spoiling and chemical imbalances.
Primary packaging also serves to keep a product in storage, often for long periods of time. The package was also used to count products that could not be counted when unpacked and their package was used as a measure (e.g. bottles, boxes, bags).
The choice of primary and/or secondary packaging materials will depend on the degree of protection required, compatibility with the contents, the filling method and cost.
