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 kind and has achieved worldwide

succes 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.

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 blade 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.

Lubricate the welding blade
periodically 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.

bell (12) and reduce the
transparency.

7.5. Rubber and teflon replacement

When the Teflon-strikers (17) 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 (18) with a detergent.

If also the rubber (18) is
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 self-adhesive Teflon­strip.
