Primary Packaging vs. Secondary Packaging: Purposes and Key Differences

Packaging is not a simple niche as it seems. Perfect packaging requires different layers of packaging, known as primary packaging, secondary packaging, and tertiary packaging. Examples of primary packaging are tubes, blister packs, and bottles. Secondary packaging examples include perfume packaging, cardboard boxes, and others. Tertiary packaging boxes are mostly shipping boxes. 

However, all these three layers of packaging are not used every time. Some products contain only primary packaging, others primary and secondary, and others contain all three packaging layers.

So, let us explore primary and secondary packaging in depth to learn all the key differences, uses, and benefits. 

What is Primary Packaging? 

Primary packaging is the basic packaging of a product that has direct contact with the product. It is the mandatory and crucial packaging ensuring product protection, preserving product quality, and maintaining product safety. It is known as the first line of defense against spoilage, damage, and contamination. Primary packing includes bottles, milk pack boxes, blister packs, tubes, and other containers holding products. 

What is Secondary Packaging? 

Secondary packaging is the second layer of the packaging. It does not have direct contact with the product but plays a crucial role in grouping, holding, and displaying the products. Designed with visuals, made of strong materials, and providing branding opportunities, secondary packaging serves many purposes from protection to product presentation. Secondary packaging examples include perfume packaging, medicine boxes, bottle boxes, cardboard carton-holding cans, and many others. 

What Is Tertiary Packaging?

Tertiary packaging is an additional packaging used after secondary or primary packaging. Its main purpose is handling bulk products, storage, and shipping. The shipping cartons and product storage boxes are the main examples of tertiary packaging.

How Secondary Packaging is Processed?

The secondary packaging is used to group primary packages. It can be done manually by putting primary packages in the secondary packaging boxes. However, now, it is done with the help of secondary packaging machines. These machines complete the process of wrapping, labeling, palletizing, and boxing. These machines reduce error chances and complete the secondary packaging process perfectly.
