Chapter 1. Foreword
1.1. Introduction
You have bought a machine with outstanding features and performance and we thank
you very much for your confidence in choosing it.
The MINIPACK System is unique in its own kind and has gained a worldwide success
with more than 50000 units operating in the field of packaging and wrapping. It is
handy, low-priced and protected by patents at home and abroad. The technological
concept underlining its design, as well as the components and materials used in the
manufacturing and testing process are the best assurance of proper operation and longlasting liability.
1.2. Performances of packaging machine
Thanks to its particular operating circuit, it can be used both as a sealing and shrinking
machine or as a plain sealing machine (sealing only).
In this case it is possible to pack the object in a soft bag without shrinkwrapping.
Technical grade or food grade films with thickness in the range of 15-50 micron can be
used. These products are manufactured and distributed by MINIPACK Torre S.p.A. The
film used in centerfolded execution can be micropunched or not when running through
the micropunches of machine itself. The machine can carry out up to 300 packages/hour.
1.3. Machine identification
In every communication with the Manufacturer, always
mention the model and the serial number specified on the
plate on the rear part of the machine.
1.4. Weight and dimensions of packed machine
a = mm 900

3.5. Roll holder adjustment
The roll holder (29) must be
adjusted according to the width of
the item to be packed, leaving at
least 1cm between the item to be
packed and the sealing edge.
3.6. Execution of 1^ film sealing
Place film as shown in the picture
to carry out the first seal.
Lower the handle of the cover
with your left hand and make a
pressure of 10-15 Kg. Machine will
automatically operate and the first
seal will be carried out on the side
of the film. With the right hand
detach the film from the sealing
blade. Film is now ready to carry
out wrapping.
3.7. Fan exhauster connection and running (where expected)

Chapter 7. Ordinary maintenance
7.1. Precautions for ordinary maintenance interventions
BEFORE PROCEEDING TO MAINTENANCE, SWITCH THE MACHINE OFF AND
DISCONNECT IT BY OPERATING ON
THE MASTER SWITCH.
7.2. Sealing wire cleaning
Using a dry cloth, wipe off the
residues clinging to the sealing
wire: do this at once after
sealing since they are
easier to remove when still
warm. Periodically lubricate the
sealing wire with the supplied
non-adhesive spray.
7.3. Plastic film and other scrap removal
Wait for the machine to cool down
completely before removing any
scraps stuck to the hot parts of the
machine (e.g. , on the flaps of the
heat chamber). If the lower cover
requires cleaning (where the fan is
installed), remove the reticulated
plate and take out any pieces that
may have fallen inside.
For a more careful cleaning of
the lower bell we recommend to
use a vacuum cleaner.
7.4. Machine cleaning
Use a cloth moistened with
water for machine cleaning.
For cleaning the hood inside and
outside we recommend to use a
normal detergent for glass
cleaning.
Do not use any detergents with
solvents which could damage
the hood and reduce the
transparency.
7.5. Rubber and teflon replacement
When the Teflon-unings (24) are
worn out, replace them with
spare parts, paying attention that
the application is linear and even.
Before applying the Teflon selfadhesive strip clean the rubber
part (31) with a detergent.
If the rubber (31) is also
damaged, replace it as follows:
Remove the old rubber, clean
its housing, apply some drops
of glue in the housing, insert
the new rubber in a linear way,
clean the rubber with a
detergent, apply the selfadhesive Teflon-strip.
7.6. Replacement of sealing wire
In order to change the sealing wire, proceed as follows:
• Push the pistons (32) all the way in using a screwdriver
• Block the tension spring by thrusting a pin (34) in the holes provided
• Using the setscrew wrench supplied, unscrew the 3 screws (33) which fasten the
wire at the centre and at the two ends so as to release the sealing wire (23)
• Replace the sealing wire (23) and tighten the locking screws (33)
• Remove the pins to enable tensioning the wire
• Make sure the sealing wire (23) is in the proper position and under the right
tension
