CASE & CARTON CLOSING ADHESIVES THAT
KEEP YOUR PACKAGING LINES MOVING

Charred glue. Webbing at the nozzle. Pop-opens on coated board. Each one slows your line, forces cleanup, or sends rejected cases back through the system.

We help plants close boxes cleanly, quickly, and without glue getting in the way.

With Capital Adhesives, you’ll eliminate the issues that stall production. Our formulas deliver strong hot tack during chill-down, clean cutoffs at speed, and thermal stability that won’t burn in the pot. That means fewer reworks, less downtime, and a smoother shift from open to seal.

Switch once. Run better every shift.

Case & Carton Adhesive Issues

FORMULATED TO REMEDY ANY ADHESIVE ISSUE

Glue problems shouldn’t cost you time, labor, or product. We help packaging lines run clean by solving the root cause, not just masking the symptoms.

Hot melt burns or chars in the tank

Black specs, odor, and uneven glue flow signal charring. Our adhesives resist thermal breakdown, so you get clean performance, even during long shifts.

Webbing or stringing

Thin webs at the nozzle build up fast, forcing cleanup and stoppage. We match viscosity and open time to eliminate stringing and keep the line moving.

Pop opens

Boxes that fail to seal cost you time and rework. Our adhesives deliver strong hot tack during chill-down, so flaps stay closed, even on coated board.

Case & Carton Substrates

BONDS THAT HOLD ACROSS EVERY BOARD GRADE

Not all adhesives hold up across today’s substrates. We design hot melts that grab, hold, and run clean on every grade—coated, uncoated, or barrier-treated.

<span>BONDS THAT HOLD</span> ACROSS EVERY BOARD GRADE

Corrugate

Formulas designed for high-volume case packing with strong grab and reliable hold across uncoated and coated corrugate, including barrier-treated e-commerce and produce boxes.

Solid Bleached Sulfate (SBS)

Delivers strong fiber tear and fast set on coated and uncoated SBS. No lift, no bleed, even with aqueous or polyethylene coatings.

Coated Unbleached Kraft (CUK)

Penetrates the kraft layer and locks the seal cleanly, reducing rejects on uncoated and coated formats running at high speed.

Coated Natural Kraft (CNK)

Ensures proper adhesion without stringing on moisture-resistant coatings. Ideal for heavy-duty or refrigerated packaging with polyethylene and barrier finishes.

Solid Unbleached Sulfate (SUS)

High tack strength and fast set time eliminate seal failures. Built for clean machining and repeatable bonds on coated and uncoated SUS.

Coated Recycled Board (CRB)

Overcomes inconsistent surface quality in recycled stocks with adhesive that holds strong and machines cleanly, even at fast line speeds.

Clay Coated News Back (CCNB)

Adhesive grabs fast and resists lift on clay-coated linerboard. Helps avoid flap separation or glue starvation common on this budget-grade board.

Uncoated Recycled Board (URB)

Tuned to bond rough, porous surfaces without oversaturation or waste. Prevents soak-in and maintains seal integrity from box-up through delivery.

Thermo Mechanical Pulp (TMP)

Provides reliable bonding on dense, fiber-rich substrates. Runs clean and sets tight—no fluttering flaps or late pops, even on fast folder-gluers.

FAQS

FREQUENTLY ASKED QUESTIONS

Your questions matter. Here are the answers to the most frequently asked questions about case and carton adhesives

Have more questions?
Get in Touch

Do you have a hot melt that will bond a digitally printed board?

Yes. We offer formulas designed for digital inks and coatings that resist bonding. You’ll get clean adhesion without scorching, stringing, or setup delays.

Do you have a hot melt adhesive that runs at 250°F instead of 350°F?

We do. Our low-temp adhesives reduce energy use and equipment wear. They’re ideal for heat-sensitive materials or temperature-restricted environments.

How quickly can I get product?

Most hot melt products ship the next day. Whether you need a sample, a pallet, or a truckload, we’ll keep you stocked and running on schedule.

Does Capital have freezer-grade hot melts?

Yes. Our freezer-grade adhesives stay flexible and hold strong at sub-zero temperatures. You can seal with confidence, even in deep freeze applications.

What volume of hot melt adhesives can I buy?

We support every volume, from a 35-pound box to a full truckload. You get exactly what you need, without overbuying or running short.

Does Capital sell hot melt purge?

Yes. We offer a purge compound that clears out residual adhesive during changeovers, so your lines stay clean and startup runs smoother.

Does Capital sell hot melt cleaner?

Yes. Our hot melt cleaner removes cured adhesive from tanks, hoses, and surfaces. It’s easy to use and prevents damage to sensitive equipment.

Does Capital provide a sample for hot melt?

Yes. We’ll send you a 10-pound sample at no cost so you can test it in your plant. No risk, no pressure, just performance.
