WATER-BASED AND HOT MELT FORMULAS THAT RUN CLEAN, SEAL FAST, AND HOLD UP THROUGH THE MAILSTREAM.
Most adhesives ship next day so you stay stocked, running, and on schedule.
We show up, run the trial with your team, and fine-tune until performance is locked in.
Every batch meets ISO 9001:2015 standards so you get consistency, compliance, and full traceability.
When envelope glue fails, it shows up everywhere. Blocking gums wreck your finish. Curling patches pull windows out of spec. And when glue splashes or strings, operators waste time wiping machines and fixing jams instead of running the line.
Capital helps you run clean, fast, and without glue-related issues getting in the way.
Our envelope adhesives are built for production precision. They dry quickly, seal evenly, and stay stable through the gumbox. Every batch is lab-tested for viscosity, wet tack, and flow so you get the same smooth run every time. Whether you’re running side seam, diagonal, or window patch, you can count on a clean seal that holds up through the mailstream.
If your current glue is slowing you down or causing rejects, it’s time to switch.

Envelope converters run fast, and there’s no margin for glue that slows you down. From blocking gums to patch skew, we help prevent the most common adhesive issues before they hit the line, so your crew stays focused, and your product stays on spec.
Envelopes stick together when front gums don’t fully cure. Our fast-drying formulas activate only during sealing, not during stacking or handling.
Windows shift out of alignment when the patch doesn’t bond on contact. Our adhesives grab fast and hold tight so everything stays straight at speed.
Glue ends up where it shouldn’t—on rollers, belts, and product. We control viscosity every batch to keep glue stable, clean, and right where it’s applied.
From front gums to window patching, our envelope adhesives are built to run clean, dry fast, and perform through the mailstream. Each type is matched to your line conditions so production stays smooth and your product stays in spec.
Resin, Residex, and hot melt formulas that apply clean, dry fast, and activate only during sealing to prevent blocking in trays or during stacking.
Natural rubber latex that forms an instant cohesive bond when pressed. Prevents curl, misalignment, and operator frustration on high-speed flap sealers.
Hot melt or water-based pressure sensitive adhesives (PSAs) that stay tacky in storage and bond reliably on contact. Ideal for long shelf life and fast, liner-backed sealing.
Resin-based formulas flow evenly and cure quickly for secure side seams that hold up under high-speed converting and mailing.
Residex chemistries that set fast, lay flat, and reduce curl. Keeps folds tight and clean through printing, folding, and inserting.
High tack formulas that hold window film securely with no shift, bleed, or curl. Machined for clean application and steady placement at speed.
No matter the style, our adhesives are tested to perform cleanly and consistently across all major envelope formats. Whether you’re sealing pointed flaps or securing full-face windows, we help keep your lines running and your mailpieces compliant, flat, and finished right.
Strong bonds and fast cure times keep pointed flaps sealed cleanly without curl, even on high-speed equipment or during tight nesting in mail trays.
Our adhesives grip securely across heavy flaps and decorative stocks. You get clean edges, no bleeding, and a finished product that holds up in transit.
Wide flap coverage and clean cutoff prevent stringing or excess glue. Formulas are built to cure evenly across flat surfaces for consistent lay-flat performance.
Reliable sealing at scale. Whether side seam or diagonal, our adhesives run fast and resist curl to support inserting, printing, and high-volume processing.
Extra surface area requires extra hold. Our adhesives deliver strong bonds across large flaps without bleed-through, blocking, or mess in the gumbox.
Our adhesives are designed to run cleanly on today’s most common envelope machines and glue heads. Whether you’re patching windows or sealing seams, we help you avoid clogs, splatter, and rework.
Whether you're forming trays or carefully assembling parts, you'll get adhesives engineered to bond at your production pace—fast or slow.
Every batch meets spec, runs the same, and stays clean through the line, so your operators don’t need to tweak settings or troubleshoot mid shift.
When something breaks, we’re there. You get fast answers and real support from people who know your machines and resolve issues quickly.
We don’t guess. We match adhesives to your substrates, machines, and conditions to get a product that runs right the first time, every time.
Products ship on time every time. No delays. No scrambling. Just predictable orders that keep your production on schedule.
With formulas designed to run clean on your machines, you skip trial-and-error, avoid jams, and get bonds that hold, no matter what.
Your questions matter. Here are the answers to the most frequently asked questions about envelope adhesives.
Yes. We can break down your current adhesive in our lab and recommend a matching or better-performing option based on your substrates, line speed, and equipment.
Yes. Our patch adhesives are built to stay stable in the gumbox and maintain clean flow through longer runs without drying out or clogging.
Yes. We offer clear and light amber options so operators can see coverage during application without it showing through the finished envelope.
Yes. Our formulas are tuned for open time and drying speed to prevent flap curl and keep product flat through mailing and inserting.
Water-based products typically last 6 months. Latex adhesives have a 3-month shelf life. Hot melts last 2 years from the date of sale when stored properly.
Yes. Most of our envelope adhesives already include UV for detection. We can also add color for visibility during production.
Water-based adhesives are available in 5-gallon pails, 30-gallon drums, 55-gallon drums, 275-gallon totes, or 40,000-pound bulk tankers.
We send 5-gallon samples at no cost so you can run a true test before switching. Every sample is backed by lab support.
Most envelope adhesives ship the next day. We keep proven formulas stocked and ready so you don’t lose time waiting on glue.
Yes. We send the sample, help with the trial, and support your team until performance is fully dialed in on your equipment.
