Introduction
If you’ve ever installed a gasket, foam pad, or adhesive-backed component, you know one of the most frustrating steps has nothing to do with performance—it’s peeling the liner. Liner removal can slow down assembly lines and cause operator aggravation. Many customers assume switching to a double-coated tape automatically solves this problem.
Does it help? Absolutely.
Does it solve everything? Not always.
What Makes Double-Coated Tapes Better for Liner Removal
A double-coated tape has adhesive on both sides of a film or tissue carrier—unlike transfer tapes, where the adhesive is unsupported. This built-in carrier gives the tape more “body,” which improves handling and liner release.
Key Advantages:
-
Improved Stiffness: The carrier keeps the adhesive from stretching during peel.
-
Cleaner Release: The liner separates more cleanly instead of stringing or tearing.
-
Better Processing: Kiss-cut parts hold shape better during converting and installation.
This is why double-coated tapes are popular in assembly operations—operators can peel the liner faster with fewer damaged parts.
Why It Doesn’t Always Solve the Problem
Even with double-coated construction, there are variables that still make liner removal difficult:
1. Small Part Size
Tiny gaskets or thin rings don’t give enough surface area to grip the liner—carrier or not.
2. Tight Inside Corners or Intricate Geometry
Complex shapes may cause the liner to tear when peeled, especially if the geometry catches the liner edge.
3. Static or “Blocking”
Some liners cling to the adhesive due to pressure, heat, or humidity during storage—making them stubborn to remove.
4. Operator Technique
Even with double-coated tape, peeling straight off the edge is harder than using a lift tab, split liner, or dry finger tab.
Real-World Manufacturing Insight
At NEDC, we see this every day. Customers often request a double-coated tape specifically for “easy peel,” and while it’s a smart move, we still recommend engineering support features when liner removal is critical:
| Enhancement | Purpose |
|---|---|
| Dry Edge / Pull Tab | Gives a finger hold for removal |
| Split Liner | Allows peeling from center rather than edge |
| Oversized Liner | More “real estate” to grab |
When a Double-Coated Tape Is Enough
Double-coated tape alone often works perfectly when:
-
Parts are large enough to grip
-
The shape is simple
-
The end-user is installing by hand (not automated)
In these cases, the added structure from the carrier makes a world of difference versus transfer tape.
When It Still Falls Short
You may still need more than just double-coated tape if:
-
Parts are very thin or small
-
Assembly gloves affect grip
-
Speed of installation is critical (assembly line / production floors)
In those cases, liner design becomes just as important as tape selection.
Conclusion
Double-coated tapes definitely improve liner removal, thanks to their carrier structure. They reduce stretching, tearing, and frustration—but they don’t completely eliminate liner challenges by themselves.
For best results, tape selection should be paired with smart part design: pull tabs, split liners, or dry edges.
