Washing
The washing instructions below apply to the cleaning of all CurTec
packaging products that are made of polyethylene and
polypropylene:
Best results will be achieved with a washing installation that is
equipped with spray nozzles or a so-called Ultra-Sonic installation.
Best qualified detergent is a low-foaming alkaline substance with
a PH-value of 10 to 12 (solvents.)
The recommended temperature of the washing water lies
between 40°C and 50°C.
The temperature of the rinsing water can only be up to 65°C.
Washing at maximum temperature can only take up to 35 seconds
and rinsing at maximum temperature only up to 20 seconds. It
prevents the plastic from warming up and shrinking.
Increased drying of products can be effected by means of applying
cold air. If warm air will be used the drying can only last up to 30
seconds at a maximum temperature of 65°C.
The blowing and drying part of the installation needs to be
adjusted to the product, so those difficult spots of the kegs can
also be dried.
For specific technical information CurTec would like to refer to the
various suppliers of washing installations.
Attention! Check the thermostat and programmed times of your
equipment regularly.

Packo manual 2020-7
01 Close
The UN marking on a Packo is only valid if the
following closing instruction is applied.
The following instruction applies to both Packo with inner seal
and lid and Packo with two-component lid. To close Packo with
two-component lid you can start at point 2.
1. Hold the container firmly with one hand. Place the inner seal
on the container with the other hand. Start on one side and then
roll down the inner seal on the edge. That way surplus air can
escape.
2. Place the lid on the container. Make a quarter turn clockwise
till it stops. The container is now completely closed.
3. Check if the teeth of the tamper evident strip exactly fit the
cavities of the container. Only then the sealing is tamper evident.

Packo manual 2020-7
02 Open
The following instruction applies to both Packo with inner seal
and lid and Packo with two-component lid. For the opening of a
Packo with a two-component lid, point 3 does not apply.
1. Hold the container firmly with one hand. Take the lip of the
tamper evident strip with your other hand and tear it off
counterclockwise. If the strip is removed the lid is ready to be
screwed off.
2. Hold the lid firmly, make a quarter turn counterclockwise then
lift it off the container.
3. Take the inner seal between your thumb and index finger and
pull it out of the container.

Packo manual 2020-7
03 Use
Filling
The temperature of the content cannot exceed 70°C. The content
has to cool down to 30°C before the container can be closed. The
drum can be closed according to instruction 1.
Freezing
Packo is made of plastic which is resistant to a minimum
temperature of -25°C. As of -5°C, shock load on the containers
should be avoided.
Attention! The volume of containers filled with water-based
contents can increase by 10%. The chances that containers will
distort are real and it will reduce the stability of a container stack
on a pallet. Please maintain a maximum filling level of 90% and
test the stability of a pallet stacking.
Air transport
During air transport, the pressure drops inside a plane’s cargo
hold, which causes air inside a package wanting to escape. After
landing, normal atmospheric pressure prevails again which,
depending on the amount of escaped air*, can cause the drum
wall to cave in.
CurTec packaging has not been designed to compensate pressure
differences. The construction is such that a correctly closed
packaging allows air to escape relatively fast, but does not allow it
to return easily.
Since CurTec has no influence on the use of its packaging by end
users, they advise to test each transport mode.
It remains the responsibility of end users to verify whether a
package and content comply with relevant transport regulations.
CurTec refers to the regulations mentioned in the UN certificates.
* The quantity depends on the content type (the shape and air between) and the
filling degree/ level

Packo manual 2020-7
04 Static load
When stacking containers for storage in e.g. a warehouse or cold
store, it is important to know what the maximum load on the
lowest container in a stack can be.
The stacking load depends strongly on: the weight of a container,
the number of containers to be stacked, the weight of interlayers
and pallets, the ambient temperature, the duration of the load
and the surface beneath the lowest container.
The following table shows the maximum stacking load (in kg) at a
given ambient temperature, during a certain period of time, for a
container placed on a flat, closed surface or pallet.

Attention! The weights mentioned in the table have been
established after simulation and can only serve as indications.
CurTec recommends users to perform tests at all times.
The table allows you to calculate the number of containers that
can be stacked: Reduce the stacking weight mentioned with the
relevant share of the weight of intermediate layers and divide by
the weight of the container with content. This number, with a
figure after the decimal point lower than 8, rounded down is the
total amount of containers that can be stacked on the lowest
container of a stack.

Packo manual 2020-7
Example
How many 500 ml Packos (art. no. 4305) with a content weighing
3 kg can be stacked on a pallet at 25°C during 2 months?
The relevant weight share of intermediate layers is 3 kg, so (15-
3)/0.85 = 14.11. The number of containers that can be stacked on
the lowest container is 14.
Attention! This data is only relevant if containers are not placed in
self-supporting cardboard boxes. The total weight of packaging
placed on a pallet may never exceed the carrying capacity of that
pallet.
In case of a different duration or temperature, please choose the
next appropriate column. For shorter stacking durations, the table
of instruction 5 (Dynamic load) can be of service.
Attention points
Before stacking the drums, the temperature of the contents must
be equal or lower than the ambient temperature.
The maximum stacking time is reduced considerably at
temperatures above 35°C. The stacking load in the table is at 50°C
only 75% of the last mentioned value and at 60°C only 50%.
When a stack is higher than 2.5 meters, the floor angle cannot
exceed 0.5%.
CurTec strongly discommends stacking containers horizontally,
lying on the side.

Packo manual 2020-7
05 Dynamic load
Before stacking Packos for transport it is important to know what
the maximum stacking load on the bottom container of the stack
is. With transport this stacking load is called dynamic load and can
be found by dividing the admissible static load by a so-called
safety factor. These factors are:
3for air transport
2for road transport
1.8for rail transport
1.3for maritime transport
The stacking weights mentioned in the table below are indicative
and depend on temperature and time: 5°C is the temperature for
cooled transport, 30°C is the temperature for the average
transport by road or inland waterways and 40°C is the
temperature for transport in warmer surroundings. In case of a
different duration or temperature below 40°C, please choose the
next appropriate column. In case of even higher temperature,
please consider that the dynamic load is at 50°C only 75% of the
last mentioned value and at 60°C only 50%

total amount of containers that can be stacked on the lowest
container of a stack.

Packo manual 2020-7
Example
How many 650 ml Packos (art. no. 4306) with a content weighing
0.7 kg can be transported by air at 30°C during 1 week?
The relevant weight share of intermediate layers is 1 kg, so
((14/3)-1)/0.7 = 5.24. The number of containers that can be
stacked on the lowest container is 5.
Attention! This data is only relevant if Packos are placed in non-
supporting cardboard boxes. The total weight of Packos placed on
a pallet may never exceed the carrying capacity of that pallet.
Attention points
When changing transport mode, from storage to shipping or vice
versa, the lowest containers of a stack must always be placed
highest in a new stack.
The containers must be stowed professionally and fixed in such a
way that makes moving impossible.
For the use of pallets, see instruction 6 (Palletization).
For stacking containers in a warehouse, see instruction 4 (Static
load).

Packo manual 2020-7
06 Palletization
Palletization
Each pallet should be fitted with a solid, flat intermediate layer
prior to loading. A pallet should have an almost closed surface
fitted with planks that are no more than 5 cm/ 2 inches apart.
CurTec advises not to exceed a total stacking height of 2 meters.
In case a pallet is placed on top of another pallet, an intermediate
layer is required to enable an equal spread of the pressure. This
layer should also be solid and flat.
Filled containers are placed on a flat surface and stacked by
placing the base of the container in the counter shape of the lid.
Packing
CurTec recommends the use of a heat shrink pallet cover, which
needs to be shrunk around the pallet as well. In addition, the base
of the pallet needs to be stretched with foil as well. The
containers at the base of a stack will carry most of the load and to
avoid a collapse they cannot be deformed by overstretching the
foil or over-heating the cover.
Attention! The total load on the bottom container of a stack may
never exceed the maximum loads as indicated in the tables of
instructions 4 and 5.
Pallet handling
From a safety point of view, CurTec recommends to transport only
one pallet at a time with a fork lift truck. In order not to disturb
the stack, the forks of the truck need to be kept almost horizontal.
