7 Must-Know Paperboard Grades for Box Printing
1. Solid Bleached Sulfate (SBS): Your Ticket to Stunning, High-End Prints
Imagine a package so striking and elegant it instantly captures the eye—that’s the magic of Solid Bleached Sulfate (SBS) at work. Crafted from 100% bleached virgin wood pulp, SBS boasts a pristine white surface, setting the benchmark for exceptional printing on paperboard boxes. Its ultra-smooth finish, enhanced by kaolin clay or mineral coatings, guarantees vivid and sharp graphics, positioning it as the top choice for luxury cosmetics, pharmaceuticals, and gourmet foods.

While it may come with a higher price tag, SBS shines with unmatched box printing quality and, when treated with a polyethylene liner, offers a robust moisture barrier for added protection.
For brands eager to stand out on crowded retail shelves, SBS is a powerful secret weapon. Its flawless aesthetic, paired with hygienic properties perfect for aroma-sensitive items like chocolates or cigarettes, elevates brand perception remarkably. Moreover, its recyclability adds a sustainable edge, supporting a circular economy while maintaining premium appeal. SBS also excels on high-speed production lines with consistent roll-to-roll quality, ensuring efficiency without sacrificing style.
Beyond its visual allure, SBS offers versatility in design, easily accommodating cuts, creases, hot foil stamping, and embossing for bespoke packaging solutions. I’ve seen businesses transform their image with SBS at C MIC Packaging, leveraging its ability to showcase vibrant designs and provide protective barriers—especially crucial for food and pharmaceutical sectors. Truly, when it comes to crafting a lasting impression, SBS is in a league of its own.

2. Folding Box Board (FBB): Strong, Light, and Earth-Friendly
Picture a packaging material as resilient as a fortress yet kind to the environment—that’s the charm of Folding Box Board (FBB). Crafted with chemical pulp outer layers and a core of bleached chemi-thermomechanical pulp, this paperboard delivers remarkable strength without unnecessary weight, generally ranging between 150-400 GSM.

Its robust stiffness and exceptional printing surface make it a top pick for health and beauty products, confectionery, and chilled goods. Moreover, its efficient design reduces material usage, thereby lowering transport expenses and shrinking your carbon footprint.
What captivates me about FBB is its versatility in design. It effortlessly accommodates complex folds and stunning, high-quality graphics through processes like offset lithography and flexography, ensuring brands stand out on the shelf. If eco-friendliness is a priority—and it ought to be—FBB dovetails seamlessly with sustainable practices, thanks to its recyclable nature and innovative coating advancements.
Delving deeper, the production of FBB is a meticulous journey involving pulping, pressing, and optional coating to boost printability. Each step adheres to strict quality controls, resulting in a smooth, durable board that’s perfect for premium packaging. From luxury chocolates to elegant perfumes, FBB not only protects but also elevates the product’s appeal with a sophisticated finish. Therefore, whether you’re aiming for eye-catching designs or green credentials, this material consistently rises to the challenge.

3. Coated Unbleached Kraft (CUK): Rugged Charm for Heavy Loads
Imagine a box that stands defiant against the toughest challenges—that’s Coated Unbleached Kraft (CUK). Crafted from unbleached virgin kraft fibers through a robust chemical pulping method known as the Kraft process, it boasts a raw, earthy brown hue and exceptional tear resistance, making it a prime choice for kraft paperboard types used in beverage carriers or sturdy retail packaging. Enhanced by a clay coating, its surface not only gains smoothness for superior printability but also offers vibrant graphics, ideal for hardware or frozen food packaging where strength outshines sheen.

CUK strikes a remarkable balance between resilience and affordability. Moreover, with additional coatings like polyethylene or wax, it combats moisture effortlessly, ensuring your products remain secure. For those prioritizing durability over dazzle in their packaging paperboard types, this material is an undeniable winner.
Delving deeper, CUK’s unbleached nature reduces environmental impact by bypassing harsh bleaching chemicals, while its recyclability aligns with sustainable practices. This makes it a thoughtful option for brands merging toughness with eco-responsibility. In industries like beverages and hardware, its ability to endure transportation rigors and storage challenges is widely valued, solidifying its reputation.

Beyond functionality, CUK impresses with versatility in design. Its natural, rugged aesthetic lends a premium touch to packaging, while supporting diverse printing techniques like flexography for creative freedom. Furthermore, strict quality controls ensure it meets high standards in tear resistance and thickness, guaranteeing reliable performance across applications.
In essence, whether safeguarding heavy tools or preserving frozen goods, CUK paperboard embodies a rugged charm. Therefore, for businesses seeking a blend of strength, sustainability, and style, it remains an unrivalled choice in the packaging realm.

4. Solid Unbleached Sulfate (SUS): Built Tough for the Hardest Jobs
Have you ever needed a box that feels like a fortress? Say hello to Solid Unbleached Sulfate (SUS), a heavyweight champion in packaging. Forged from unbleached softwood pulp, it boasts unrivalled rigidity and resilience, often outshining other types of carton board when the stakes are high. Its earthy brown hue may not scream sophistication, but with a slick clay coating, it transforms into a canvas ready for sharp, clear printing—perfect for robust packaging like electronics or detergent boxes.

SUS stands as the silent guardian for hefty products. Its unbleached pulp retains natural lignin, amplifying its durability, while the absence of bleaching chemicals makes it a greener, cost-effective choice compared to pricier alternatives. This blend of strength and sustainability is a boon for B2B buyers who value practicality. At C MIC Packaging, I regularly guide clients towards SUS when they demand packaging as tough as nails for bulky or heavy goods.
What’s more, SUS isn’t just raw power—it’s adaptable. A clay coating not only boosts its printability for bold branding on consumer goods but also shields it from moisture and wear, extending its shelf life. From automotive parts to hefty electronic components, SUS is a go-to in industries where protection is non-negotiable. Its ability to bear heavy loads without flinching makes it indispensable.
Beyond brute strength, SUS offers surprising flexibility. Innovative online tools at companies like C MIC Packaging let clients customise their boxes, picking templates and refining designs with expert consultation to elevate both function and marketing impact. Therefore, whether it’s heavy machinery parts or industrial tools, SUS can be tailored to fit unique needs while retaining its ironclad core.
Lastly, consider the real-world impact: a company shipping heavy machinery parts swapped to SUS from a costlier bleached option and slashed expenses without sacrificing strength. Indeed, as this case illustrates, SUS not only safeguards goods during transit but also boosts customer trust by minimising damage. So, when durability meets affordability, SUS proves itself as the ultimate packaging ally.

5. Coated Recycled Board (CRB) or Clay Coated News Back (CCNB): Wallet-Friendly and Green
Imagine a packaging solution that balances your budget while nurturing the planet—this is the charm of Coated Recycled Board (CRB), often known as Clay Coated News Back (CCNB). Crafted from recycled materials like discarded newspapers and used corrugated boxes, this versatile paperboard is topped with a smooth white clay layer, typically kaolin, to ensure decent printing quality. It shines in applications for dry foods, laundry items, and pet supplies—ideal for scenarios where moisture isn’t a concern.

Although it may lack the sturdiness of virgin fiber options like SBS, CRB stands tall as an affordable, earth-friendly choice. Its production slashes the need for fresh wood pulp, conserves resources, and often demands less energy and water, trimming costs further. However, beware of humid conditions, as they aren’t its forte. Nevertheless, for those balancing tight finances with green aspirations, this material proves a worthy ally.
Beyond cost, CRB offers a canvas for creativity with customizable options like cutting, embossing, or hot-foil stamping, enabling brands to craft eye-catching packaging. The clay coating not only boosts surface brightness but also ensures sharp, vivid graphics—perfect for shelf appeal. Moreover, its high recycled content supports a closed-loop system, cutting landfill waste and enhancing sustainability credentials.

Importantly, CRB and CCNB adhere to strict industry standards, especially crucial in food and pharmaceutical packaging. They are engineered to be food-safe, meeting rigorous regulatory benchmarks to uphold consumer trust. For instance, a cereal brand switching to CRB might not only slash production costs and carbon footprints but also elevate its eco-conscious image among buyers.
Ultimately, this paperboard blends economic savvy with environmental care. Therefore, whether you’re a manufacturer seeking savings or a brand aiming to stand out sustainably, CRB delivers on both fronts. Its fusion of affordability, customization, and green benefits makes it a compelling choice in the packaging realm.

6. Non-Bending Chipboard: Rock-Solid Support for Luxury Packaging
Imagine a box that holds its ground, unyielding under pressure—that’s the essence of Non-Bending Chipboard. Crafted from compressed recycled fibres like old newspapers and corrugated cardboard, this robust paperboard, with a thickness ranging from 0.5 to 1.5 mm, forms the unbreakable core of rigid set-up boxes for premium products such as jewellery and electronics. Unlike flexible materials, it’s designed not to bend, serving as a steadfast foundation often draped in decorative finishes for both safeguarding and sophistication.

While direct printing on this dense material may not yield the best results, its true strength lies in elevating high-end packaging. Enhanced by modern techniques, such as high-pressure pressing to remove air pockets, this chipboard ensures uniform density and unmatched durability. Wrapped in elegant paper, foil, or fabric, it not only protects but also transforms into a visual delight, embodying the essence of luxury.
Indeed, Non-Bending Chipboard is a cost-effective hero in the world of upscale unboxing. Its ability to be precisely cut or moulded into intricate shapes using advanced technology allows brands to craft bespoke designs that mirror their unique identity. Moreover, as a product of recycled materials, it champions sustainability, aligning with eco-conscious trends by reducing reliance on virgin resources and supporting a circular economy.
Furthermore, its impact on customer experience is profound, as seen in real-world applications by luxury jewellery brands. The chipboard’s sturdy nature minimizes damage during transit, ensuring precious items arrive pristine, thus boosting customer trust. In fact, industry experts highlight how its premium feel and resilience create memorable unboxing moments, reflecting a brand’s commitment to quality and detail.
Ultimately, this material stands as a quiet yet powerful force in luxury packaging. Its blend of strength, customisation, and environmental benefits makes it a preferred choice for brands aiming to marry elegance with responsibility. Truly, Non-Bending Chipboard is the bedrock of unforgettable first impressions.

7. MET-PET Board: Dazzling Flair That Turns Heads
Picture a package that gleams like a polished treasure on the shelf—that’s MET-PET Board, a standout paperboard for packaging, crafted by layering a metallized polyester film, often over Solid Bleached Sulfate. With finishes in shimmering silver, lavish gold, or striking patterns, it’s an irresistible lure for media, medical, or display boxes. Its glossy sheen transforms ordinary box printing materials into a luxurious spectacle that captures every wandering eye.

Though it might not match the sheer durability of SUS or CUK, MET-PET Board dazzles with its unmatched visual allure. For promotional campaigns or high-end retail boxes where first impressions are everything, this material steals the show. I’ve witnessed its spellbinding effect as brands snag instant attention with just a glance.
Beyond its beauty, MET-PET Board is engineered through a fascinating metallization process, where a thin layer of metal, typically aluminum, is vacuum-deposited onto the polyester film. This not only heightens its aesthetic charm but also boosts barrier properties, shielding against moisture, oxygen, and light—ideal for safeguarding sensitive products. Moreover, the metal coating adds electrical conductivity, making it detectable by metal detectors, a handy feature for safety compliance in items like microwave dishes.
Customization is another feather in its cap, as MET-PET Board supports an array of printing techniques for stunning graphics and designs. Whether adorned with metallic inks, embossed details, or hot foil stamping, it crafts a premium look that elevates brand identity. Indeed, packaging experts often praise its ability to stand out on crowded shelves, turning a simple box into a powerful marketing asset.

However, sustainability remains a point to ponder. While the metallized film can be recyclable in some instances, the metal layer may complicate the process. Thankfully, emerging recycling innovations are tackling these hurdles, and some manufacturers are pioneering greener metallization methods. Thus, the allure of MET-PET doesn’t just stop at aesthetics—it evolves with a conscience.
Take, for instance, a luxury cosmetics brand that embraced MET-PET Board for their custom cosmetic packaging. The result? A dazzling unboxing experience with a metallic finish that boosted brand visibility and deepened customer loyalty. It’s a testament to how this material doesn’t just package a product; it wraps it in prestige, ensuring it lingers in the consumer’s mind.
