Introduction

As consumers become more concerned about food safety and the environment, they’re increasingly choosing food packaging that is both safe and eco-friendly. So, how can you meet these demands while building a strong brand image? Using food-grade Coated Board with Kraft Back (CKB) paper for packaging is a smart choice. Want to learn more about CKB paper? Keep reading, and I’ll explain what it is, its advantages, and its applications.

What is CKB?

CKB stands for Coated Board with Kraft Back. It’s a type of Kraft paper that’s coated on one side, usually white, and has a brown kraft color on the other side. The typical grammage ranges from 190gsm to 335gsm.

Advantages of CKB

Food-Safe and Eco-Friendly

Our CKB paper at Golden Paper is food-grade and made from 100% pure wood pulp. It’s unbleached, meaning it doesn’t contain harmful chemicals, fluorescent agents, or plasticizers, making it both safe for food contact and environmentally friendly. It also meets the certification standards for food packaging boards both domestically and internationally.

Superior Strength and Durability

Because CKB is made from 100% virgin fiber and is unbleached, it retains more natural wood lignin, giving it stronger, more tightly bound fibers. This increases its overall toughness, resulting in better physical properties like hardness, stiffness, and tear resistance.

Moisture Resistance

The long fibers used in CKB increase its durability and tear resistance. This fiber structure helps the paper distribute pressure evenly, reducing the risk of tears. The multiple coating layers also improve printability while adding a protective barrier that helps prevent moisture from seeping through, further boosting its moisture resistance and durability.

Applications of CKB

Thanks to its excellent physical properties and eco-friendly nature, CKB is widely used in food packaging. It’s commonly used for products like frozen foods, beverages in bottles or cans, and cold drinks that require refrigeration. The food-safe certification of CKB makes it perfect for direct food contact, so it’s also commonly used for packaging items like bread, burgers, pizza, and takeout.
