This clear finish, cured with ultraviolet light, adds durability, enhances visuals, and aligns with eco-friendly trends—making it a go-to for businesses wanting to stand out.
The global UV coatings market is on a steep climb, projected to grow from USD 4.46 billion in 2024 to USD 8.73 billion by 2037 at a 5.3% CAGR, per Research Nester. Why the surge? It’s fast, protective, and gives packaging that premium edge customers notice—70% judge products by their look. This guide breaks down UV coating’s essentials, from how it works to why it’s a fit for your paperboard packaging needs.
What is UV Coating?
UV coating is a surface treatment where a clear, liquid compound—typically composed of polymer resins—is applied to substrates such as paper, cardboard, or plastic. This liquid is then cured instantly using ultraviolet light, hardening in milliseconds to form a durable, glossy, or matte finish. In packaging, UV coating is a staple for paperboard boxes and folding cartons, enhancing both protection and aesthetics with a premium look.
The process, developed in the 1960s for industrial use and refined over decades, is solvent-free, emitting no volatile organic compounds (VOCs), making it a cleaner alternative to traditional coatings like varnish. UV coating’s versatility shines in the printing industry—think business cards, brochures, and retail-ready folding cartons—where it adds a tactile, high-end feel. At BrillPack, we see it as a cost-effective way to elevate your brand’s first impression.
The Science Behind UV Coating: How It Works
UV coating starts with a liquid blend—think polymer resins mixed with photoinitiators, polyethylene, and kaolinite. This compound gets applied to paperboard or folding cartons, setting the stage for a transformation. It’s a precise step, tailored to the packaging’s needs, whether it’s a full glossy coat or a subtle highlight.
The application method varies based on the job. Rollers spread it evenly for broad coverage, silkscreen tackles detailed patterns, and spray works for textured surfaces. Once applied, the magic happens: ultraviolet (UV) light hits the liquid, sparking a photochemical reaction. Photoinitiators absorb UV energy, break down, and kickstart rapid polymerization—hardening the coating in milliseconds.
This curing process is lightning-fast, running at 100–800 feet per minute. It happens on specialized machines—conveyor belts paired with high-intensity UV lamps (100–700 watts per inch). The result? A tough, protective layer with no mess or waiting, unlike traditional drying methods that drag on.
Why does this matter for packaging? For high-volume folding carton runs, instant curing cuts downtime and speeds up shipping. After curing, the paperboard’s ready to cut, fold, or pack—no extra steps needed. BrillPack recently saw this in action: a client’s paperboard box run with spot UV coating highlighted logos post-printing, slashing production time by 20%. It’s simple science with a big payoff—UV light turns a liquid into a durable, eye-catching finish, perfect for paperboard packaging.

Types of UV Coating
UV coating comes in several flavors, each tailored to specific needs for paperboard packaging and printing. It’s not a one-size-fits-all solution—whether you want bold shine or subtle elegance, there’s a type that fits. Here’s a rundown of the main options, plus a lesser-known gem, and how they can work for your folding cartons or boxes.
Gloss UV Coating
Gloss UV delivers a shiny, reflective finish that screams attention. It’s the top pick for folding cartons needing a vibrant punch—like food packaging (e.g., cereal boxes) or cosmetics craving shelf appeal. The high sheen boosts color depth, making dark tones pop. Brands love it for retail-ready products where first impressions drive sales—it’s bold, durable, and hard to miss.
Matte UV Coating
Matte UV offers a smooth, non-reflective look with a touch of class. Perfect for paperboard boxes aiming for a luxurious, understated vibe—think high-end retail like jewelry or premium candles. It resists fingerprints better than gloss, keeping packaging pristine.
Spot UV Coating
Spot UV zeroes in on specific areas—like logos or text—for a textured, standout effect. It’s a favorite for folding cartons wanting contrast, pairing a glossy highlight with a matte base. Think of a skincare box where the brand name shines while the rest stays subtle. It’s cost-effective for small accents, adding depth without coating everything—BrillPack uses it to make designs pop affordably.
Soft-Touch UV Coating
Soft-touch UV brings a velvety, tactile finish that feels upscale. It’s ideal for paperboard packaging aiming for a premium unboxing experience—like luxury soaps or tech gadgets. The soft texture invites touch, enhancing perceived value, though it’s pricier than standard options.
Reverse UV Coating
Reverse UV flips the script: it leaves a matte finish on coated areas while the uncoated paperboard stays glossy from prior printing. This “strike-through” effect creates a unique contrast—great for folding cartons needing a modern twist, like artisanal food packs or promo items. It’s less common but growing in demand for its artsy vibe—BrillPack’s experimenting with it for creative clients who want to stand apart.
Each type serves a purpose—gloss for flash, matte for finesse, spot for focus, soft-touch for luxury, and reverse for flair. Picking the right one depends on your paperboard packaging goals, and at brillpack.com, we’ve got the know-how to match your vision.
Applications of UV Coating in Packaging and Printing
UV coating’s versatility makes it a standout across industries, especially for paperboard packaging. It doesn’t just protect—it elevates products, from everyday essentials to luxury goods, with a finish that’s both functional and eye-catching. Here’s where it shines and why it matters for small businesses looking to level up.
Folding Cartons
UV coating transforms folding cartons for food, cosmetics, and pharmaceuticals into durable, shelf-ready packages. Cereal boxes get a glossy sheen that resists scuffs during shipping, while makeup boxes—like a lipstick carton—gain vibrant colors that pop under store lights. For pharma, it adds a protective layer to pill packs, ensuring labels stay legible. A 2023 Packaging World survey found 60% of retailers saw sales lifts with UV-coated cartons, thanks to enhanced appeal. It’s a small tweak with big returns.

UV Coating vs. Other Finishes
UV coating isn’t just another finish—it’s a contender with distinct advantages over alternatives for paperboard packaging. Let’s break down how it stacks up against aqueous coating, lamination, and varnish, focusing on durability, cost, and practical use.
UV coating Vs. Aqueous Coating
UV coating outshines aqueous with superior hardness and durability. Its glossy finish holds up under heavy handling—think folding cartons tossed in shopping bags—while aqueous, a water-based option, offers moderate protection at a lower cost ($0.02–$0.10/sq in vs. UV’s $0.05–$0.20). Aqueous dries in minutes, not instantly, and fades faster, making it better for low-touch paperboard like one-time mailers. UV’s the pick for lasting impact.
UV coating Vs. Lamination
Compared to lamination, UV coating is thinner, more flexible, and budget-friendly for folding cartons. Lamination, with its plastic film ($0.10–$0.50/sq in), delivers high durability but adds bulk—great for heavy-duty paperboard boxes but overkill for retail display. UV’s spot application option (e.g., highlighting a logo) gives it an edge; lamination can’t match that precision. BrillPack clients often choose UV for its cost-effective versatility over lamination’s heft.
UV coating Vs. Varnish
UV coating leaves varnish in the dust with instant curing and better scratch resistance. Varnish, at $0.03–$0.15/sq in, dries slowly (hours, not milliseconds), offering less protection for paperboard boxes under wear—like a candle box rubbed in transit. UV’s speed suits high-volume runs, while varnish fits basic, low-budget needs. For paperboard that needs to endure, UV wins hands down.
For paperboard packaging, UV coating’s blend of speed, finish, and toughness makes it a standout. The table below sums it up—compare and see why it’s a BrillPack favorite for folding cartons and beyond.
