3 Key Types of Packaging & When to Use Them

Most packaging decisions are not about finding the “best” option. They are about finding the right fit for your product, your timeline, and where your brand is headed next.

That is where things can get complicated, but lucky for you, we work with brands every day on exactly this.

Nutraceutical startups figuring out their first label.

Pet brands that have outgrown their original packaging.

Produce companies ready to take the next step at retail.

Every conversation is a little different, but the underlying question is almost always the same: what packaging actually makes sense for where we are right now?

There is no formula for that, but there is experience. And after working with brands at every stage of growth, we have learned a lot about what tends to work, what does not, and how to tell the difference early.

If you have ever felt stuck between moving fast and getting it right, you are in good company.

What Are the Main Types of Packaging?

Types of packaging refer to the different formats used to protect, transport, and present products.

For most consumer brands, packaging decisions typically come down to three core packaging formats:

• Pressure sensitive labels
• Flexible packaging
• Folding carton

Each of these packaging formats plays a different role depending on the product, the retail environment, and how the brand plans to grow.

There is no one-size-fits-all answer here. The right choice depends on what your product needs today and where you want to take it next.

Understanding the Three Levels of Packaging

Before choosing a packaging format, it helps to step back and look at the bigger picture.

Most products move through three packaging levels that work together as a complete packaging system.

Primary Packaging

Primary packaging is what directly holds the product. It is the part your customer actually interacts with. 

Examples include:  

• A pouch holding snack food  

• A bottle with a pressure sensitive label  

• A tray of ready-to-eat food with lidding film 

Belmark’s pressure sensitive labels, flexible packaging, lidding film, and pouches are all commonly used as primary packaging because they come into direct contact with the product. 

This layer is all about product protection and maintaining shelf quality. For many products, especially food packaging, getting this right is critical. 

Secondary Packaging

Secondary packaging brings products together and helps them show up well in retail environments. 

Examples include:  

• Folding cartons that hold a product package  

• Multi packs of snacks  

• Retail ready packaging that displays multiple units  

Belmark’s folding cartons often play this role by grouping or enclosing primary packaging while helping products stand out on the shelf. 

This is where branding, merchandising, and product protection start working together. 

Tertiary Packaging

Tertiary packaging supports movement through the supply chain. 

Examples include:  

• Corrugated boxes 

• Shipping cases  

• Pallets  

• Bulk transport packaging  

Customers may never see this layer, but it plays a major role in how efficiently products move from production to retail shelves. 

A Quick Note: Tertiary packaging like corrugated boxes and shipping cases falls  outside of what Belmark provides. Our expertise lives in the primary and secondary  packaging that your customers actually see and interact with. If you have questions about how it all fits together, our packaging experts are happy to help point you in the  right direction. 

When all three levels work together, packaging becomes more than a container. It becomes a system that supports your product from start to finish. 

The 3 Core Types of Packaging Brands Use Most Often

While there are many packaging formats, most consumer products rely on three main approaches:

• Pressure sensitive labels applied to a container
• Flexible packaging that holds or seals the product
• Folding cartons that add structure and presentation

Each one solves a different problem.

Most growing brands end up using more than one. The real question is which format makes sense for which product, and how that picture changes as your lineup grows.

When to Choose Pressure Sensitive Labels

Pressure-sensitive labels do one thing really well — they give brands versatility and a billboard to shine, no matter how small.

They are applied to containers like bottles, jars, and tubs and are widely used across distillery, nutraceutical, pet, produce, ready-to-eat, snack, and cheese products.

Beyond the container itself, they open the door to a wide range of custom embellishments that can really make a product stand out on the shelf.

Pressure sensitive labels make sense when:

• You are using an existing container
• You expect to introduce multiple SKUs or flavors
• You want to play with specialty embellishments and finishes

They allow you to maintain consistent branding while adapting your packaging over time.

When Flexible Packaging Makes Sense

When brands want full creative control and packaging that’s easy for customers to grab and go, flexible packaging tends to be the answer.

You will see it used across nutraceutical, pet, produce, ready-to-eat, and snack products — in formats like pouches, rollstock film, and lidding film, each suited to different product and retail needs.

It is a strong fit when you want packaging that:

• Allows for entire package customization
• Supports multiple product variations
• Connects with customers at shelf based on category norms

Flexible packaging gives brands the ability to create strong shelf presence while keeping operations efficient.

The right format depends on your product, how it’s sold, and how it moves through your supply chain, and that conversation looks a little different for everyone. This is where having a packaging partner can make a big difference.

When Folding Cartons Are the Right Fit

Folding cartons come into play when structure and presentation need to be considered as well.

They are commonly used for craft beer, nutraceutical, health & beauty, ready-to-eat, jerky, and specialty products, especially when shelf visibility is important.

Folding cartons are often used when:

• Your product is sold in multiples (think variety packs or a 4 pack of beer)
• A product needs added protection
• Retail presentation plays a big role in purchasing decisions
• You want to create a stronger shelf presence
• Products are displayed directly on shelves

It is not always one or the other. Often, it is a combination.

What Packaging Is Designed to Do

Packaging does more than hold a product.

At its core, product packaging supports a few key goals:

Shelf Appeal

Helping products stand out and maintain a strong presence in retail environments.

Product Information

Communicating what the product is and how to use it.

Distribution Efficiency

Helping products move efficiently through distribution networks.

When these elements work together, packaging becomes part of the product experience.

Product Protection

Protecting the product through manufacturing, transportation, and storage.

How Packaging Choices Evolve as Brands Grow

One of the biggest misconceptions about packaging is that you have to choose one format and stick with it.

Packaging strategies change. Products get added. Retail opportunities open up. What worked at launch does not always work two years later, and that is a good thing. It usually means the brand is growing.

Take a nutraceutical brand that starts with a single supplement in a bottle. Pressure-sensitive labels make total sense. Then they add a powder. Now a pouch is in the conversation. Then a retail partnership comes along and suddenly a folding carton is the right call for how the product needs to show up on shelf. Same brand, three formats, all for good reason.

We see this kind of evolution all the time.

The trickier question is knowing when the timing is right to make a change. Some signs worth paying attention to:

• Your lineup is growing and your current format feels like a stretch for certain products
• You are moving into a new retail environment with different display expectations
• Your brand has matured and your packaging has not kept up
• A new product just needs something different to stand out to keep up with trends

There is no universal answer for when to make the move. But it is a lot easier to navigate when you have a partner who has been through it before and knows the right questions to ask.

Sustainability Considerations in Packaging

Sustainability is becoming an important part of packaging decisions for many brands.

At Belmark, we support this through two sustainable packaging approaches:

Tru-IMPACT® focuses on reducing waste through responsibly sourced materials and recycled content.

Eco-READY™ focuses on recyclable packaging solutions.

Both approaches help brands move toward eco-friendly packaging while maintaining shelf quality and performance.

Choosing the Right Packaging Partner

Packaging decisions do not end when the order ships. New products get added. Retail environments change. Brands grow in directions nobody predicted. The partner you choose should be able to grow right along with you.

That is what we have built Belmark to do.

We work with brands at every stage — from a founder packaging their first product to an established brand refreshing a national line. And because we offer total packaging solutions across pressure-sensitive labels, flexible packaging, and folding cartons, brands rarely have to look elsewhere as their needs evolve. One partner, one relationship, from 1 to 1,000,000+ units.

What we hear most from brands who work with us is that they did not expect the level of care and responsiveness they got. We move fast, we are flexible in ways larger suppliers simply are not, and we stay invested in your business long after the order is delivered.

If you are figuring out which packaging format is right for your product or wondering whether your current packaging is still the right fit, that is exactly the kind of conversation we love to have.
