Concentrated Envelope Sealing Solution Powder (Makes 1 Gallon)

The Smarter, Greener, and More Cost-Effective Way to Seal Your Envelopes.

  • 95% Less Plastic Eliminate Jug Waste
  • Cut Shipping CO2 by over 98%
  • Universal Formula For All Major Brands

Stop Paying to Ship Water and Plastic

Traditional envelope sealing fluid is over 99% water. When you buy a 1-gallon jug, you're paying for the water, the heavy plastic container, and the fuel to ship 8.5 pounds of liquid across the country. Our concentrated powder eliminates this massive inefficiency. You provide the water, and we provide the savings and sustainability. It's the simple, intelligent choice for any modern mailroom.

How It Works: Premium Sealer in 3 Simple Steps

  1. SOURCE: Obtain a clean, one-gallon container and fill it with deionized or distilled water (preferred for best results).
  2. MIX: Carefully cut open the packet and pour the entire contents of the concentrated powder into the water.
  3. SHAKE: Seal the container and shake well for 30 seconds until the powder is fully dissolved. You now have one gallon of high-performance sealing solution.

The Twin-Engine Advantage: Save Money & The Planet

Switching to our concentrated solution delivers a powerful one-two punch of benefits. You dramatically lower your total costs while simultaneously achieving your company's sustainability goals. See how it stacks up against the traditional 1-gallon jug:

Frequently Asked Questions

Is this really compatible with my Pitney Bowes® machine?

Yes. Our formula is engineered to be 100% compatible and is a direct replacement for Pitney Bowes® E-Z Seal® and other OEM solutions. It will not harm your machine or void your warranty.

Do I have to use distilled or deionized water?

We strongly recommend using distilled or deionized water for optimal performance and to prevent mineral buildup in your machine over time. You can purchase it for about a dollar at any supermarket. In a pinch, standard tap water will work, but we do not recommend using well water due to its high mineral content.

How much plastic does this actually save?



A typical 1-gallon plastic jug weighs over 60 grams. Our powder packet and its minimal packaging weigh less than 5 grams. That's a reduction in plastic waste of more than 95% for every single gallon you use. For a business using 40 gallons a year, that's over 5 pounds of plastic jugs you've kept out of the landfill.

Why didn't someone make this sooner?

This stuff is great. Frees up so much space in my already cramped supply room and saves us a fortune on shipping. We used to get a pallet of 40 jugs, or a 50 gallon drum, now I can keep the same supply in a small box. Brilliant.
