Three Side Seal vs Quad Seal Pouches: Which One Is Right for Your Product?

Ever wondered if your packaging suits your product or not? It’s a question almost every brand keeps looking for answers to. They keep coming up with several packaging solutions until they find the right one. If the packaging is too feeble, your product looks droopy. If you pick one that’s too heavy, you exceed your budget.

Being a business in Canada, finding the right package is all about survival. If you are confused between the efficiency of three side seal pouches and quad seal pouches, you are in the right place. In this blog, we will learn all the key differences and discover which one suits your product best.  

Improper pouch sealing can damage your product. It results in waste of materials, effort, and cost. It doesn’t matter if you are packaging food products or pharmaceuticals. Your packaging sealing affects your product from production to shelf. 

What Is Exactly a Three-Side Seal Pouch? 

As the name suggests, custom three side seal bags are pouches that are heat-sealed from three sides. One side is left open for filling the product. They are sealed from the left, right, and bottom, and the top side is left open. They have a single-use application. 

Example: They are commonly used to package powder, granules, snacks, etc. 

What Is Exactly A Quad Seal Pouch?
As the name says, custom quad seal bags are sealed from all four sides. They completely trap the product contents inside. They are very refined and look like a square shape. Custom quad seal pouches are used for products that need extra protection from environmental factors. 

Example: Pet food, medicines, premium coffee and tea.
