How important is the type of paperboard used for folding carton?

Most people focus on printing or design, but the type of paperboard decides how strong and functional a folding carton can be.

The type of paperboard used is very important because it affects strength, print quality, durability, and product protection, making it a key factor in folding carton performance.

Choosing the right material is not simple. I learned this when a customer’s display collapsed during shipping because the paperboard was too thin. Since then, I always focus on material first.

What material is used in folding cartons?

Many people think folding cartons are all the same, but the base material can change how the packaging looks and works.

Folding cartons are usually made from paperboard, including solid bleached sulfate (SBS), coated unbleached kraft (CUK), and recycled paperboard, chosen based on strength, printability, and cost.

Types of materials

When I started working in this field, I was surprised to find out that even the same product can use different grades of paperboard. Some buyers want a premium white finish¹, others focus on cost. The most common options are listed below:

These materials matter because customers expect packaging that both protects and represents their brand. A luxury perfume carton needs a smooth white finish. A heavy soda pack needs strong kraft board. I often guide buyers by comparing their product weight and marketing goals.

What is the purpose of paperboard packaging?

At first glance, paperboard packaging looks like only a way to hold products, but in practice it does much more.

The purpose of paperboard packaging is to protect products, provide a surface for branding and printing, and ensure products are easy to store, ship, and display.

More than protection

I remember working with a hunting gear buyer. He wanted cartons that could survive long shipping and still look sharp in store displays. Protection² was his first concern, but brand presentation mattered just as much. Paperboard makes this balance possible.

This is why I always ask clients about both logistics and marketing goals. The right paperboard can reduce damage claims while also improving shelf appeal.

What kind of paper is used in carton boxes?

Many buyers mix up corrugated boxes and folding cartons, but the type of paper used is different and specific.

Carton boxes are generally made from paperboard, which can be solid bleached sulfate, unbleached kraft, or recycled fibers, each selected for strength, cost, and appearance.

Why it matters

A client once asked me why his cartons collapsed during transport. He had chosen recycled paperboard⁴ to cut costs, but the load was too heavy. We switched to kraft-based paperboard⁵, and the problem was solved.

This shows why paper type is not just about price. The right choice can prevent losses and improve customer satisfaction.

Why folding box board is used for cereal boxes?

Every morning, millions of people open a cereal box, but few think about why that specific board is chosen.

Folding box board is used for cereal boxes because it is lightweight, printable, food-safe, and strong enough to protect the product while keeping costs low.

The cereal packaging⁶ balance

I once toured a cereal factory and saw how many cartons move on the line each hour. The paperboard must fold easily, print beautifully, and still protect delicate flakes inside. This is why folding box board dominates the cereal sector.

If a brand uses the wrong board, the box may sag, the print may fade, or food safety may be at risk. Folding box board⁷ solves all of these problems.

Conclusion

The type of paperboard defines strength, looks, and trust in folding cartons, making it the foundation of good packaging.
