What is STACLEAN paper?(Dust-Free paper)

Our STACLEAN is mainly made of wood pulp, and a kind of impregnated paper. Instead of pigment, cellulose fiber is fused(or bonded) by a kind of resin. As a result, any dust is not almost generated form edge or surface.

The reason which keeps being chosen 1 

Quality emphasis/Low particles

The important point with clean paper is that it does not generate dust. The following are the measured values at our company.

Customized STACLEAN Paper Products

STACLEAN paper has many kinds of papers which can be used inside cleanroom.STACLEAN papers can be converted customized products for cleanroom use, if necessary.

Adoption case 1: Interleaf Paper

"Wrap-50" & "NIL 70" are economical paper and generates less particles than Kraft Paper. Surface pH is controlled around 7.0 and used interleaf paper.

Interleaf Paper application
As interleaf for metal products.
As a mount sheet in the inspection process.
As packing material.


Adoption case 2: Wafer Spacer

This is used for a semiconductor, liquid crystal or electronic products to transport and safe keep. It's called on the high quqlity without "tamper-proof packing", "Anti-Static", "corrosion" "blush friction blemish" and to be able to be elaborate.


Wafer Spacer features
Excellent dust-control performance.
pH is controlled in neutral.
The smooth surface protects wafer from scratching.
Can be burned after using.
Various size & thickness are available.


Adoption case 3: Lead Frame spacer


Lead Frame spacer features
Excellent dust-control performance.
pH is controlled in neutral.
The smooth surface protects wafer from scratching.
Can be burned after using.
Various size & thickness are available.
