Nothing is more frustrating than trying to slide a gatefold into a brand-new outer sleeve only to watch the side seam split apart.

Or pulling a favorite record off the shelf and hearing that unmistakable ripping sound as the sleeve tears open.

It happens every day, and most collectors assume it's just part of owning records.

It isn't.

Most outer sleeves are built with a structural weak point that eventually fails. Once you understand why, it's hard to ignore—and even harder to go back to sleeves built the old way.

The Weak Point Most Sleeves Share

Most polypropylene record sleeves are made from two flat sheets of plastic that are heat-sealed together along both sides and the bottom.

The downside is that every time you slide a record in or out, those side seams take the stress.

Polypropylene is naturally rigid—that's one of the reasons it's so crystal clear. But that rigidity also means the heat-sealed seam becomes the weakest part of the sleeve. Over time, every insertion, every removal, and every trip on and off the shelf puts more strain on that same point.

Eventually, the seam loses.

Small Failure. Bigger Consequences.

A split seam might seem like a minor annoyance, but it's more than cosmetic.

Once the side opens up, the album jacket is no longer fully protected. Dust can enter. Jacket edges become exposed. Corners begin rubbing against neighboring records. Little bits of shelf wear accumulate over months and years.

Ironically, the sleeve stops doing the very job it was meant to do.

Collectors who regularly play their records often notice this much sooner than someone whose collection mostly stays on the shelf.

Why Most Sleeves Are Still Made This Way

The answer is simple.

Side-sealed sleeves are easier and less expensive to manufacture.

For decades, that's been the industry standard. Most manufacturers never invested in a different production process because the existing method was "good enough."

But good enough isn't always the best solution.

A Better Way to Build a Sleeve

When we developed ClearKeep outer sleeves, eliminating weak side seams was one of our priorities.

Instead of sealing both sides, our sleeves are bottom sealed.

The polypropylene is folded to create continuous side edges, leaving only a single seal along the bottom—an area that experiences very little stress during normal handling.

That means there are no side seams waiting to split when you're sliding records in and out.

It's a small design change, but one you'll notice immediately.

The sleeve feels stronger. More substantial. More durable.

We paired that construction with crystal-clear 3.5 mil polypropylene to create a sleeve that doesn't just protect your collection—it also lets your cover art shine the way it was meant to.

Outer Sleeves Shouldn't be Disposable

If you've invested time building a collection, every record deserves protection that lasts as long as the album inside.

That's why we built ClearKeep differently.

No weak side seams.

Just crystal-clear protection designed to stand up to years of collecting, browsing, and listening.

If you've ever been frustrated by split seams, we think you'll notice the difference the very first time you use a ClearKeep sleeve.
