If we keep the first meaning of container that mentions the dictionary of the Royal Spanish Academy (RAE ), the term refers to act and the result of packaging : Place a liquid or other substance in a container.
The most common use of the notion, however, is associated with container in itself. That is to say that a container is an object that allows storage and transport of certain products .
There are multiple types of packaging since the packaged elements can be very diverse. The glass or plastic bottles and the tetrabriks , for example, are the most frequent packages of drinks . Cookies, meanwhile, are usually marketed in plastic, paper or cardboard containers .
The characteristics of the package depend on what it contains, since it must ensure adequate hoarding, protection, handling and distribution of the product . A soda or soda, to name a case, cannot be packaged in paper since the container would get wet and spoil. The most fragile goods, on the other hand, need a shock-resistant container.
He material Used to manufacture each type of packaging is a fundamental point, which not only affects the quality and conservation of the product it contains, but also marks a trend and identifies it with an era. For example, while yogurt used to be distributed in glass containers until the late 1980s, plastic is currently used.
Caring for environment , on the other hand, requires the use of reusable or recyclable containers to minimize waste generation. Glass bottles, in this sense, are valuable as they can be refilled after being subjected to a comprehensive cleaning and disinfection process. Some plastic bottles can also be recycled: they are melted and then used as raw material for the production of new containers or other products.
According to the criteria applied, there are several ways to classify containers. One of them is based on the distance between them and the products they contain, and this results in the following three types: primary, secondary and tertiary . The primary container is in Contact direct with the product, so that it not only serves to contain it but also to protect it.
In a commercial store, each primary packaging corresponds to a unit of the product in question and is oriented to the consumer final, that is, it is not intended for wholesalers. Although it can cover the product partially or totally, it guarantees that the product cannot be modified without the container being opened. Soft drinks are sold in this type of container.
On the other hand we have the secondary container , which is also known as collective and is used to contain one or more primary containers, with the aim of protecting them during the commercial distribution process. In a store, we can find it in packages of several units, either for sale to the final consumer to keep them close to the shelves for eventual replacement. Transparent plastic films that group several bottles of mineral water are a clear example of this type of packaging.
He tertiary container Finally, it is the one used to transport or group containers of any of the two types above in a container which gives them protection in the vehicles that take them along the commercial distribution network. They are manufactured with the aim of making transport and handling of many units easier, minimizing the chances of damage and alterations. Two clear examples of this kind of packaging are reusable plastic boxes and pallets.
