Paper products
Paper products
SCA Publication Papers and Sustainable Packaging produce wood containing printing papers and packaging materials. The range includes LWC, Uncoated offset, Newsprint and light weight packaging papers. Lightweight coated paper (LWC) is essentially a thin paper made from ground spruce pulpwood, reinforced with a small proportion of kraft pulp to add strength. The resulting paper is then covered with coating in which the most important constituent is fine-grained clay.
Uncoated offset paper and newsprint paper are made from fresh spruce pulp wood.
Sustainable Packaging products are made from ground spruce pulp-wood, reinforced in some products to a large extend of kraft pulp to add strength. The Splendo and Operio products have also an extrusion coating.
Depending on the paper grade different clamping forces are recom-mended. If the clamping force is too high there is a risk that the reel may become oval shaped.
Wrapping protects the paper
The wrapping is a PE-paper laminate which provides a water vapour barrier and protects the reels against humidity and water. This means that the reels can handle light rain and dry snow. However the reel cannot stand in water or resist water under pressure. The wrapper also provides good protection against mechanical damage, dirt and airborne impurities, and is well suited for material recycling.
Unloading
On arrival
Before unloading begins please check the reels for any damage. If any damage is found, a remark must be made on the way bill (carriers and receivers).
The truck floor must be swept regularly. Even a very small stone or screw etc. can cause severe damage to the reel.
Be cautious of protruding lashing points, do not push or drag the reels when unloading!
Storage
Use reel guards.
Ensure reels are correctly stacked within the bays. Careless driving can cause severe damage to the reels.
Leave adequate space between the stacks.
In the warehouse
If possible divide the floor space in to bays and number them. Plan the bays so that different marks/lots are always accessible, avoiding unnecessary handling.
It is essential that the area is swept regularly; even a very small
stone or screw can cause severe damage to the reel. The place of storage must be dry. Never place a reel in water. Always control the free height and distance when lifting and
lowering in the stack.
Uneven stacking can cause edge damage and even serious accidents from falling reels.
Clamping force
Clamping force
Clamping force is usually measured in kiloNewton (kN). 1 kN (1000 N) corresponds to a weight of approximately 100 kg on the reel. 30 kN corresponds to a weight of 3000 kg on the reel.
Maximum clamping force according to
reel weight
Paper quality Pressure factor
Uncoated offset and Newsprint 1.0-1.4 Sustainable Packaging – Puro
LWC 1.7-2.0
Sustainable Packaging – Splendo, Operio
Example:
Total paper weight 2000 kg × factor 1.3 = total pressure = 26 kN.
Clamping force should be checked regularly, there are several different devices available for this purpose.
Smart-Intelligent clamping systems
These systems automatically regulate the clamp pressure to ensure that only the minimum required force is used at all times throughout the handling operation. This greatly reduces the risk for out-of-roundness and dropped reels.
Why the correct clamping force is
necessary
Excessive force can cause: • Reel deformation
• Reel out-of roundness (oval) • Reel core damage
Insufficient force can cause: • Reel to drop
• Reel to slide/telescope
Please contact SCA Technical Support if you have any que-ries concerning the correct clamping force for SCA reels. Contact information is to be found at:
Clamping force
Check list for the correct clamp:
• Weight of reels to be handled• Max- and min diameter • Reel width
• Clamping force required
• Type of friction surface (clamp pad) • Storage and stowage pattern • Number of reels per handling • Rotation
Check list for the correct lift truck:
• Type of clamp• Lifting capacity • Height of stowage
• Hydraulic functions pressure and flow • Tilting functions
Handling
Overloading/Incorrect handling
To compensate for the extra weight of the free riding reels the clamping force can increase significantly above the recommended level, which can result in out of roundness. This practise is also dangerous for persons nearby as the free riding reels can easily fall and cause serious injury or even death.
Risk for deformation and out of roundness. Always place the pad in the centre of the reel.
Risk for edge damage and deformation. Always place the pads in the centre of the reels.
Always control the distance to the floor before rotating. Never drive with a horizontal reel.
Contact pads
Contact pads are the most important part of the clamp. In most handling situations, the pads are the only part of the clamp in contact with the reels.
Regular maintenance is essential. Control and clean the
friction surface, and check the pad for damaged/sharp edges as these can cause severe damage.
Worn pads can require up to 3-4 times more clamping force than a clamp in good condition. Re-surface or replace worn pads.
YYABBCCCDDZZZZ SCA’s reel numbers
Reel number identification
The reel numbers look like this:
YYABBCCCDDZZZZ
YY = Year
A = Paper machine number
BB = Production week (54, 55 rewinded reels) CCC = Tambour number during the week DD = Set and position in the set
ZZZZ = 1876 is the number for Ortviken paper mill We use 001-399 in even years and 501-899 in odd years. 01-15 for the reels from set 1.
16-30 for the reels from set 2. 31-45 for reels from set 3.
Reels with numbers 1, 15, 16, 30, 31 and so on are the edge reels.
The IFRA Code
ABBCCCDD-EEEEFGZZA = Paper machine number
BB = Production week (54, 55 rewinded reels) CCC = Tambour number during the week DD = Set number and position in the set EEEE = Brutto weight in kilo
F = Reels per pack, 1 or 2
G = Grammage code used for Newsprint ZZ = 76 is the number for Ortviken paper mill
Claim routines
Copy of the commercial invoice
This document confirms the value of the goods. It also shows the delivery terms and who is on risk during the transport and consequently in the right of compensation under the transport (cargo) insurance.
Copy of the way bill
The way bill proofs that a transport has been carried out. It also shows the name of the carrier.
Claim against the carrier
• A remark in the way bill must be made to proof the con-
dition of the goods at the time of delivery into the custody of the buyer/receiver.
• If there is no remark in the way bill, it is considered that
the goods is delivered in sound condition according transport law.
• The remark has to be made for visible damage or dam-
mage that should have been visible if a control had been carried out.
Important: the remark has to be made in the carriers and receivers copy of the way bill.
Why the documentation is important
In order to seek any compensation from the carriers a fully completed and correctly signed consignment note and copy of the commercial invoice needs to accompany any subse-quent claim.
To receive compensation from the
tran-sportation company or cargo insurance
Should any goods be rejected at the point of delivery they will remain the property of the mill, who together with SCA claims department and cargo underwriters will decide what action to take for their disposal.
Several options are available;
• Negotiate a discounted rate for the goods
• Mill looks to sell off the goods to an interested third
party
• Make arrangements for collection and transportation
back to the terminal
• Insurance company takes over ownership and control of
the goods products
