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.

01 Close
The UN marking on a drum is only valid if the
following closing instruction is applied.
1. Put the lid on the drum and turn it clockwise until it is tight.
2. Turn the lid 30° clockwise using a tool. Only now the drum is
closed liquid tight and the UN marking is valid.
3. After closing the drum you can make the container tamper
evident. For that purpose the lid and the container have sealing
loops. CurTec advises you to use Unisto Compact seals.
Put the tail of the sealing strip into the sealing loops of the lid and
drum. Push the tail trough the eye of the sealing strip and pull
close.
Vaten gebruiksaanwizjing 2020-7
4. The drum is now sealed.
Remark: Sealing the drum is not a requirement for the validity of
the UN marking
Vaten gebruiksaanwizjing 2020-7
02 Open
1. In case a drum is sealed, tear the seal and remove it from the
loops.
2. Turn the lid counter-clockwise to open.
Unstacking
Due to the weight of the stack on top, the rubber gasket can get
compressed and needs time to recover. After unstacking, CurTec
strongly advises users to leave the drums in an upright position for
at least 15 minutes prior to opening. This allows the rubber gasket
to return to its original shape and guarantee an optimal closure.
Drums 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.
Lifting
Depending on the type of drum, you can lift the container by using
the large handgrips on the body or the handgrips on the lid.
Attention! Please consider the HSE regulations regarding weight
and frequency restrictions for lifting
Charging the handgrip
The mounted handgrips have been designed for manual
displacement of drums only. They are are not suitable for
mechnical handling, such as lifting a drum with a hoist. The
handgrip is suited for a brief, controlled charge of maximum 80 kg
and a couple of minutes, during which the handgrip canot be
torqued.
Freezing
The drums are made of plastic which is resistant to a minimum
temperature of -25°C. As of -5°C, shock load on the drums should
be avoided.
Attention! The volume of drums filled with water-based contents
can increase by 10%. The chances that drums will distort is real
and it will reduce the stability of a drum stack on a pallet. Please
maintain a maximum filling level of 90% and test the stability of a
pallet stacking.
Drums manual 2020-7
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 alllows 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

When stacking drums for storage in e.g. a warehouse or cold
store, it is important to know what the maximum load on the
lowest drum in a stack can be.
The stacking load depends strongly on: the weight of a drum, the
number of drums to be stacked, the weight of interlayers and
pallets, the ambient temperature, the duration of the load and
the surface beneath the lowest drum.
The following table shows the maximum stacking load (in kg) at a
given ambient temperature, during a certain period of time, for a
drum 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.
Drums manual 2020-7
The table allows you to calculate the number of drums 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 drum with content. This number, with a figure after
the decimal point lower than 8, rounded down is the total amount
of drums that can be stacked on the lowest drum of a stack.
Example
How many 15 liter drums (art. no. 7015) with a content weighing
15 kg can be stacked on a pallet at 15°C during 1 month?
The relevant weight share of intermediate layers is 5 kg, so
(98-5)/15 = 6.2. The number of drums that can be stacked on the
lowest drum is 6.
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 drums horizontally, lying
on the side.
When changing transport mode, from storage to shipping or vice
versa, the lowest drums of a stack must always be placed highest
in a new stack.

When stacking drums for transport, it is important to know what
the maximum load on the lowest drum in a stack can be.
For 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:
3 for air transport
2 for road transport
1.8 for rail transport
1.3 for maritime transport
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.
Drums manual 2020-7
The stacking weights mentioned in the table above 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%.
The table allows you to calculate the number of drums 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 drum with content. This number, with a figure after
the decimal point lower than 8, rounded down is the total amount
of drums that can be stacked on the lowest drum of a stack.
Example
How many 15 liter drums (art. no. 7015) with a content weighing
13 kg can be transported by rail at 3°C during 1.5 weeks?
The relevant weight share of intermediate layers is 7 kg, so
(145-7)/(13x1.8) = 5.89. The number of drums that can be stacked
on the lowest drum is 6.
Attention points
When changing transport mode, from storage to shipping or vice
versa, the lowest drums of a stack must always be placed highest
in a new stack.
The drums 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 drums in a warehouse, see instruction 4 (Static load).
Drums 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 drums are placed on a flat surface and stacked by placing
the base of the drum 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 drums 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.
When positioning the drums on a pallet it is important to turn the
handgrips away from the pallet corners to avoid damaging the
heat shrink pallet cover or the stretch foil.
Attention! The total load on the bottom drum 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.
Pallet schemes
CurTec advises you to respect the following quantities per layer:
