1. Flexible Yet Durable
CKB paper has a tight fiber structure that ensures superior strength while remaining flexible. It resists cracking during folding, creasing, or die-cutting, ensuring clean lines and strong edges in box production.
2. Eco-Friendly and Biodegradable
Manufactured from unbleached virgin kraft pulp, CKB maintains its natural brown color and contains no harmful bleaching agents. It is FSC-certified, ensuring responsible forest sourcing, and is fully biodegradable and compostable.
3. Excellent Printability
The coated surface provides good print adhesion, making it suitable for custom branding, logos, or food-safe labeling in sustainable packaging.
4. Barrier Performance (When Treated)
When paired with PLA coating or wax lamination, CKB paper offers enhanced resistance to moisture, grease, and temperature, making it a strong performer in demanding food applications.
Application of CKB
1.High-Temperature and Frozen Food Packaging
CKB with PLA coating is safe for both freezing and microwave heating. It withstands temperatures from -25°C to 120°C, making it suitable for takeaway containers, meal trays, and lunch boxes.
2. Greaseproof Fast Food Wrapping
Wax-coated CKB paper is ideal for hamburger wrappers, french fry sleeves, and fried chicken buckets, offering strong grease resistance without compromising recyclability.
3. Eco-Friendly Consumer Packaging
CKB is a popular choice for packaging natural cosmetics, sustainable groceries, and eco-conscious retail goods due to its kraft appearance and environmental profile.
4.Carrier and Protective Boxes
Thanks to its rigidity and strength, CKB is also used in carrier cartons, beverage sleeves, and protective inserts.
Q1: Is CKB safe for direct food contact?
Yes, unbleached CKB paper with PLA or food-grade wax coatings meets international food safety standards and is approved for direct food contact.
Q2: Can CKB be printed or branded?
Absolutely. The coated surface allows for offset, flexo, or digital printing. It accepts inks well and maintains vibrant, consistent branding results.
Q3: How sustainable is CKB paper compared to other packaging boards?
CKB is more environmentally friendly due to its unbleached base, biodegradability, and FSC-certified sourcing. It’s often chosen as a sustainable alternative to bleached and synthetic-coated boards.
Q4: What are the available grammages or thicknesses?
CKB paper is available in a wide range of grammages, typically from 190gsm to 350gsm, and can be customized in both roll and sheet formats.
Q5: How does CKB compare to traditional duplex or white back board?
CKB has a natural brown back (kraft) instead of a grey or white back, offering better sustainability, rigidity, and grease resistance in food packaging applications.
