As a company that’s been a leader in the packaging industry for more than 30 years, there’s one thing we here at Praxis can say for certain: all packaging is not created equal.

No matter what kind of products your company makes–food, pharmaceuticals, health and beauty, electronics–you need packaging that can keep the content safe, aid in transportation and storage, and effectively market your product to consumers.

To do that, you need both primary packaging and secondary packaging. Though both forms of packaging have much in common, they have just as many key differences. Each one serves a distinct function in the protection, identification, and distribution of your product, while working in tandem to safeguard that product throughout its lifecycle.

But what exactly is primary vs. secondary packaging? As always, Praxis is here to provide expert insights. Below, we’ll explain the similarities and differences between primary packaging and secondary packaging, while also detailing why they’re both so important.

No one knows packaging better than Praxis. Let us put our expertise to work for you.

Primary vs. Secondary Packaging: What’s the Difference?

Primary Packaging

Primary packaging refers to the immediate packaging that directly contains the product. It is in direct contact with the product and is responsible for preserving its chemical, physical, and biological stability. Primary packaging materials must be compatible with the product ensuring it remains potent and effective while also being safe for consumer use.

Functions of Primary Packaging

  • Protection: Primary packaging shields the product from external elements such as light, moisture, air, and contamination, preventing degradation and maintaining its quality.
  • Dosage and Administration: For pharmaceutical products, it allows for precise measurement and administration of the drug, ensuring accurate dosage intake by patients.
    Identification: Primary packaging includes labeling with essential information like product name, expiration date, and manufacturer details for easy identification and safety compliance.

Common Materials Used in Primary Packaging

  • Glass: Commonly used for bottles and jars, as well as vials and ampoules due to its inert nature, transparency, and ability to preserve product purity.
  • Plastic: Used for bottles, containers, and blister packs; chosen for its flexibility, lightweight nature, and cost-effectiveness.
  • Metal: Utilized in aerosol cans or as foil due to its barrier properties against moisture and gasses.

Secondary Packaging

Secondary packaging surrounds the primary packaging, serving as an additional layer of protection during storage, transportation, and distribution. It doesn’t directly interact with the product but provides essential support and information to users and logistics handlers.

Functions of Secondary Packaging

  • Protection During Transit: It shields primary packaging from physical damage, temperature variations, and external hazards during transportation and storage.
    Brand Identification: Secondary packaging often includes branding, promotional material, and additional product information to attract consumers and differentiate the product in the market.
  • Regulatory Compliance: It accommodates space for mandatory regulatory information, warnings, and instructions for safe use, ensuring compliance with legal requirements.

Common Materials Used in Secondary Packaging

  • Cardboard/Paperboard: Commonly used for cartons, boxes, and outer packaging due to its durability, printability for branding, and eco-friendliness.
  • Plastic Films: Utilized for shrink-wrapping or as overwraps to group multiple units together, providing additional protection and tamper evidence.
  • Foam Inserts: Used to cushion and secure products within the secondary packaging, preventing movement and reducing the risk of damage during transit.
