Why Use Hot Melt Adhesive and Release Liner Instead of Finished Double-Sided Tape?

Finished double-sided tape is convenient.

But for high-volume packaging production, convenience does not always mean flexibility or cost efficiency.

Many manufacturers need adhesive materials with specific widths, lengths, glue quantities, or application patterns.

This is where hot melt adhesive + release liner technology provides another option.

The traditional process is relatively simple:

However, finished tape usually comes with predetermined specifications.

When the product changes, the tape specification may also need to change.

This can create challenges related to:

KQ Automation provides an alternative process:

The adhesive can be applied onto the release liner and then transferred to the product.

This creates a more flexible adhesive production process.

Hot melt adhesive is applied onto the release liner and transferred through a roller system.

This method is suitable for producing an adhesive layer on the liner.

Hot melt adhesive is applied directly onto the product surface.

This can be useful for products with customized adhesive requirements.

One major advantage is adjustability.

Depending on the application, KQ's solution can adjust:

This provides greater flexibility compared with purchasing finished tape with fixed specifications.

According to KQ's application experience, the solution is particularly relevant to high-consumption packaging products such as:

For these applications, adhesive consumption can be significant, making adhesive material cost an important consideration.

The internal KQ training material notes that, for certain high-consumption applications, the hot melt adhesive + release liner approach may reduce adhesive material costs compared with purchased double-sided tape. Actual savings depend on the adhesive, product structure, consumption, and production conditions, so testing is recommended before making a project-level cost claim.

The real value is not simply replacing double-sided tape.

It is combining:

into one controlled production process.

For packaging manufacturers looking for more flexible adhesive application, this approach can open up new possibilities for production optimization.
