What does the term "primary packing" refer to?

The term "primary packing" specifically refers to the packaging that directly contains the product for sale. This type of packing serves as the first layer of packaging surrounding the product and is essential for protecting it from environmental factors, ensuring hygiene, and facilitating handling and transportation. Primary packing is critical for the product’s presentation and branding, as it is usually what consumers see first. It can include features such as labels, seals, and containers that provide information about the product and ensure its safety and quality.

In this context, the other options don't match the definition of primary packing. For instance, packaging for shipment refers to secondary packing, which is concerned with the outer packaging that facilitates transport. The process of labeling products is not about the packaging itself but rather focusing on the information provided on the packaging. Lastly, the method of storing products is unrelated to how the product is packaged for sale. Thus, the definition of primary packing specifically relates to the immediate containment of the product.
