RECOMMENDATIONS
Centerfold shrink film will not
separate or open.
If shrink film appears to be single sheet, place a strip of tape on top of
the film and on the bottom and pull apart to initially separate.
Film appears to smoke or is
sticking to wire when seal is
made.
This can mean one of several things:
1. With PP or PO film, wire must be kept clean by removing sealing
pad and depressing arm until wire burns clean all film residue.
No teflon tape required on arm.
2. PVC film will smoke when seal is made. Teflon tape over the
heating element will prevent the film from smoking and will
occasionally need to be replaced.
For teflon tape or other
parts, call Uline at 1-800-295-5510.
Burning holes in shrink film with
the heat gun.
If gun is set on high temperature and held in the same spot for more
than a few seconds, the film will burn. Gun should be continually
moving in a circular spiral motion from the outside edges of the
package first, and to the middle of the package last.
Arm is not properly cutting
and sealing shrink film.
1. On/Off switch may not be turned on.
2. Timer on Industrial model may not be set properly.
3. Arm may not be in complete contact with pad. (Gentle Pressure).
4. Excessive pressure applied to sealing arm.
5. Wire may need cleaning.
Setting timer properly.
Timer should be set to allow the minimal amount of time necessary
to cut and seal the film. The setting will vary according to type of film
in use. Setting timer too high will burn the film. PVC film will require a
lower setting than most other films. Timer may need to be adjusted to
lower setting if machine is used in a continuous or rapid manner.
Package is ballooning when
the film is heated.
The air inside the package expands as the film is heated. The quickest
way to vent the film is to cut an asterisk (*) into the closed end of the
centerfold. The smaller your package, the more lines you should cut to
make sure every package has at least one vent hole.
