Film
Typical problems, Follow list for topic in sequence, the first solution will be the most common.
Film is foggy, on rollers and in lamination
Decrease speed
Increase temperature
Defective Film
Film is foggy, clear on rollers foggy in lamination Decrease temperature
Defective Film
Film does not stick / poor adhesion Decrease speed
Increase temperature
Increase roller Pressure
Incompatible film adhesive with project
Defective Film
Bubbles / air pockets in film only, not near edge Film is not running flat at nip, increase tension
Film is not running flat at nip, decrease tension
Not enough pressure for application, increase
To much pressure (rollers bending), decrease
Defective Film
Bubbles / air pockets in lamination See troubleshooting for film
Defective Film
Bubbles in edge seal Not enough pressure available, increase
Paper to thick for film / laminator
Speed to great to conform, Slower
Temperature to low for adhesive flow, increase
Film to thin for adhesive flow
Bubbles between sheets perpendicular to rollers Not enough pressure available, increase
To much pressure (rollers bending), decrease
Film to thin for adhesive flow
Temperature to low for adhesive flow, increase
Sheets to close, allow more space
Bubbles in edge seal parallel to the rollers Too hot, decrease temperature
Blistering / random bubbles on paper Too hot, decrease temperature
Paper moisture content too high
Incompatible film / temperature for the ink used
Defective Film
Optical distortion in film / wavy / puddles Too hot for film base, decrease temperature
Too slow – Film base distorting, speed up
Too Much Pressure, decrease
Defective Film
Optical distortion in film parallel to rollers Motor pulsating, increase speed
Motor pulsating, reduce mandrel tension
Supply roll bouncing, increase mandrel tension
Film stretching and rebounding, decrease tension
Roller pressure too great, reduce
Irregular bonding Decrease speed
Increase roller pressure
Defective Film
