Peel, Stick, Win: The Tin Can Closure Changing Coffee Packaging

Here’s the thing about traditional tin cans: they’re awesome. They look premium, protect coffee from oxygen and moisture, and offer a sturdy, reusable alternative to bags. But there was one big catch: Sealing them required a $3,000 seamer (yikes) or renting one, which still wasn’t ideal for small-batch roasters.

That’s where the idea for Peel & Stick was born. We knew roasters loved tin cans but needed an easier, more cost-effective way to use them. So, we thought: What if sealing a tin can was as easy as applying a sticker?

Light bulb moment! Eureka! Enter Peel & Stick—the first hand-applied tin can end on the market. No bulky equipment. No sky-high investments. Just a secure, resealable closure that keeps coffee fresh with an integrated degassing valve. And the best part? It works with all our 4-inch, 5.5-inch, and 7-inch tin cans.

Creating Peel & Stick wasn’t as simple as slapping an adhesive on a tin can and calling it a day. The label itself has a complex, multi-layered construction. It had to:

• Create an airtight, tamper-evident seal.

• Include a degassing valve to protect freshness.

• Be easy to apply, peel off, and reclose—without losing its effectiveness.

It took rounds of testing and some very creative problem-solving, but once we landed on the perfect design, customers embraced it immediately—and by now, it’s clear it’s a pretty big hit.

Roasters are all about offering the best, freshest coffee, and customers want packaging that looks great and works effortlessly. Peel & Stick delivers on both fronts, offering three major benefits that have made it a success:

1. No Seamer? No Problem.

Like we mentioned before, in a time before Peel & Stick, sealing a tin can meant investing in a heavy, pricey, and maintenance-heavy seamer. That worked for some, but for smaller roasters, it was a huge barrier to entry.

Now, with Peel & Stick, tin cans are more accessible than ever—even for roasters working on short-run seasonal blends, special releases, or small-batch offerings. In fact, we offer ready-to-use patterns and easy design tools in Roastar Design Lab that are perfect just for those short runs. Roasters can order as few as one tin can, and it includes our Peel & Stick!

2. Reuse & Refill = Real Sustainability

Tin cans are already highly sustainable because they’re recyclable, but reusing them is even better. Peel & Stick allows roasters to set up refill programs, where customers can bring back their cans for a discount on fresh beans. Café Domestique in Madison, WI, is doing exactly that. They sell all their coffee in Roastar tin cans, and their customers love the sturdy, reusable packaging. Instead of tossing out a bag every time they switch up their brew, customers can bring their can back, seal it with a fresh Peel & Stick closure, and save money while reducing waste.

3. Freshness Without the Fuss

This isn’t just any sticker—it’s an engineered tin can end with a built-in one-way degassing valve. That means coffee can release CO₂ without letting oxygen in, keeping it fresh for longer. And because it’s resealable, customers can keep their beans at peak quality without worrying about awkward workarounds (looking at you, rubber bands and plastic clips).

There’s a reason Peel & Stick is winning awards left and right—it’s a totally new way to seal coffee. But what really sets it apart?

It feels intuitive. Some innovative packaging looks cool but leaves customers confused (how do I open this without destroying it?). Peel & Stick makes tin cans feel familiar and easy while offering an upgrade in freshness and reusability.

It’s built for coffee. This isn’t just a sticker slapped onto a can. It’s designed with the same barrier protection, degassing, and tamper evidence that roasters rely on.

It’s flexible. Roasters can order just the Peel & Stick closures (in units of 100) for their refill programs or buy the cans and closures together for a premium, shelf-ready product.

With more roasters adopting Peel & Stick and more customers loving the convenience of refillable tin cans, we’re excited to see how this game-changing closure continues to evolve.
