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 long-lasting 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.

according to the height of the product
to pack. To position it follow this
procedure:
Pull the reticulated plate in direction of
the arrows
Remove it from the stops
Position the plate on the stops at the
required height
N.B.: For a proper packaging the
reticulated plate must be positioned
so that film sealing is at the half of
the package height.
3.4. Packaging plate adjustment
The packaging plate (10) must be
adjusted according to the width of the
item to be packed, leaving a space of
about 1-2 cm between the item and
the sealing edge.
3.5. 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.
3.6. Introducing the object to be wrapped
With the left hand slide on the
packaging plate the quantity of film
necessary to contain the product to
be packed.
Introduce the product into the bag
using the right hand and make it
slide to the left until it is layed on
the screen leaving a little space fo
about 1-2 cm to allow the passage of
air for shrinkwrapping.
3.7. Making up
By pushing the cover handle with a
pressure of 10-15 Kg. the cover rests
on the sealing blade; by pinching the
film, it is automatically sealed on
the open sides (right and front). In
case you have selected the function
“SEALING +
SHRINKWRAPPING” you will see
the film shrink onto the product.
Slightly decrease the pressure on the
cover handle to allow film detach
from the sealing area on the inside.
With the right and detach the film
from the sealing blade towards the
outside.

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 nonadhesive 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

for the cleaning of the machine.
For cleaning the bell inside and
outside we recommend to use a normal
detergent for glass cleaning.
Do not use any detergents with
solvents which could damage the
bell 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, and apply the selfadhesive Teflon-strip.
7.6. Changing the sealing wire
