Grade specific

Remoistenable Film & Re-Tack Window

1

Coat 3–6%

Below 3% the film is too thin to carry enough adhesive; above 6% it curls on the roll and blocks in storage.

2

Dry, then activate

Drying temperature sets the re-tack speed. Higher drying leaves a harder film that needs more water and a longer dwell.

3

Control humid climates

Add a release layer or back coating where relative humidity stays above 70% — it stops blocking without changing the adhesive face.

Processing Guidelines

Make-down. Disperse in room-temperature water first, then raise to 70–80 °C to finish dissolution. Typical solution strength is 5–10%. Always add flake into water, never water onto flake, and filter through 60–80 mesh. Strong alkali will cut viscosity — keep pH below 9 unless the formula calls for it.
Concentration. Work at the strength the application needs — adding water later to a gelled batch does not restore the film.
Filtration. Screen the solution before it reaches the machine; gel particles that pass are defects that cannot be removed downstream.
