Billerud AB / Henry Cooke Ltd

OFT closed case: Anticipated acquisition by Billerud AB of Henry Cooke Limited.

Affected market: Sack and kraft paper

No. ME/1545/03

The OFT's Decision on reference under section 33 given on 18 February 2004.

Please note text in square brackets indicates range inserted at request of parties.


Billerud AB (Billerud) is listed on the Stockholm Stock Exchange.  It is active in the supply of sack and kraft paper, containerboard and paper pulp.  In the financial year to 31 December 2002, Billerud's worldwide turnover was approximately £528.2 million.

Henry Cooke Limited (Henry Cooke) is active in the supply of technical kraft paper.  In the financial year to 30 September 2002, Henry Cooke's worldwide turnover was £28.5 million of which approximately £ 9.9 million was made in the UK.


Billerud proposes to acquire the share capital of Henry Cooke for (see [note 1]).  The parties notified the transaction on Monday 22 December 2003 and the 40 working day administrative deadline expires on Monday 23 February 2004.


As a result of this transaction Billerud and Henry Cooke will cease to be distinct.  The parties overlap in the supply of technical kraft paper and the share of supply test in section 23 of the Enterprise Act 2002 appears to be met.  The OFT believes that it is or may be the case that a relevant merger situation has been created for the purposes of section 33(1)(a) of the Act.


Product market

The parties overlap in the supply of a variety of sack and kraft paper products.  Sack and kraft paper is made from wood pulp produced by a modified sulphate pulping process.  It is principally used by converters to produce industrial sacks, consumer bags, wrapping paper and flexible packaging.

The range of sack and kraft paper products supplied by the parties includes a particular type of technical kraft paper for medical packaging and wraps (Medical Packaging Paper).

Medical Packaging Paper differs from other types of sack and kraft paper in that it allows the contents of the packaging to be sterilised and keeps the contents sterile until use.  The immediate customers of Medical Packaging Paper are converters which use it to produce medical packages in which end users, such as medical device manufacturers and hospitals, package items such as syringes and other surgical instruments.

Our investigation considered whether converters and end-users could use alternative materials to Medical Packaging Paper for sterilisation purposes.  The parties estimate that only 45 per cent of medical packaging is made from paper and information provided by them suggests that alternative materials, such as flexible film and non-woven materials, could be used.

However, our own investigation does not wholly support the parties' view.  Some converters state that they can only use paper to produce packaging as their machinery is not suitable for flexible film or other materials.  Other converters that do use flexible film indicate that some products require both paper and film resulting in a package that is one side film and one side paper.  The use of paper is essential if the end user requires steam sterilisation as its porous properties allows steam to enter and exit whilst still providing a barrier to bacteria and other pathogens.

The parties, however, argue that steam sterilisation accounts for only around 8 per cent of medical products and steam is only one of four possible sterilisation forms, the others being ethylene oxide, gamma radiation and gas plasma sterilisation.  Nonetheless, our investigation shows that for a number of end-users, who rely on the steam sterilisation process, there appear to be no suitable alternatives for Medical Packaging Paper.

Our investigation also assessed the ease with which sack and kraft paper suppliers presently not active in the supply of Medical Packaging Paper could switch to producing it within one year.  Some sack and kraft paper suppliers were relatively confident that they might be able to switch.  However, due to quality testing requirements of converters and customers, it was estimated that it might take six months to two years to switch.

Overall in this case, it has not been necessary to conclude definitively on product market definition.  Therefore, the appropriate frames of reference are considered to be the supply of sack and kraft paper and the supply of Medical Packaging Paper.

Geographic market

The principal suppliers of Medical Packaging Paper in the UK are French based Arjo Wiggins SA; Billerud situated in Sweden; and Henry Cooke based in the UK.  A significant proportion of paper, including Medical Packaging Paper is supplied across borders.  The OFT's own investigation shows that there appear to be no significant barriers to cross border trading.  In this case, therefore, the appropriate geographic frame of reference is considered to be at least Europe wide.


Market shares

By their own admission, the parties have been unable to provide reliable share of supply data in this case.  However, in the supply of sack and kraft paper in the EU, the parties estimate that post merger they will have a combined share of [10-20 per cent] by volume with an increment of [less than 10 per cent].

There seems to be little prospect of any competition concerns arising in this sector as there appear to be a large number of alternative suppliers (over thirty in number) operating within Europe as well as suppliers in the Far-East and in South America which appear to be able to supply UK and other European customers.

In the supply of Medical Packaging Paper, neither the parties nor third parties contacted by the OFT were certain as to how many suppliers are active in this sector.  Nevertheless, the parties together with Arjo Wiggins are recognised as the major players.  The parties estimate their combined share of supply in the UK at [35-45 per cent] by volume, with an increment of less than [5 per cent], and in the EU at [35-45 per cent] [increment 15-25 per cent] by volume and [20-30 per cent] [increment 10-20 per cent] by value.  Arjo Wiggins estimates its share of supply in the UK at 30-40 per cent (see [note 2]).  The parties submit that there are a number of other suppliers, including US based Kimberley Clarke.  However, we were unable to confirm this during our investigation.

It appears, therefore, that the merger may lead to a reduction from three to two major players in the supply of Medical Packaging Paper in Europe.  Prima facie, this gives rise to the potential for the merger to lessen competition in this sector.  However, the ability of producers of sack and kraft paper to switch to supplying Medical Packaging Paper (see paragraph 11 above) and the limited barriers to entry and expansion into this sector discussed below are likely to act as competitive constraints on the parties post merger.

Barriers to entry and expansion

Our investigation shows that de novo entry into the supply of Medical Packaging Paper would be costly and time consuming requiring around £100m investment and taking two years to begin production.

In contrast, entry by firms currently active in the supply of other paper types, in particular sack and kraft paper, appears to be much easier.  Most of their plant and machinery can be easily adapted to produce Medical Packaging Paper and in some cases firms believe that they already have the technical capability.  Third parties suggest that clean room facilities and a calendar machine are required to control porosity.  The cost of switching is estimated at around £3.5m depending on existing plant and setup.

The main obstacle for existing sack and kraft paper suppliers appears to be customers' quality control requirements to ensure absolute cleanliness and the attainment of UK and EU certification.  These can be lengthy processes and take six months to two years to complete.

In addition, barriers to expansion in the Medical Packaging Paper segment also appear to be low.  In particular, information provided by the parties and the OFT's own investigation indicate that existing sack and kraft paper producers have sufficient capacity to facilitate both their entry and expansion.

Buyer power

Our investigation revealed no evidence to suggest that converters or end-users have any buyer power.


This transaction appears to raise no vertical concerns.


No competitors expressed concerns about the merger.  Most customers were also unconcerned.  However, a few expressed concerns about the possibility that the merger may give the parties considerable market power and lead to poorer service levels.  One customer was concerned about the time and cost implications of having to switch suppliers.


The parties overlap in the supply of various types of sack and kraft paper products.  The only potential area of concern appears to be the supply of sack and kraft paper for medical packaging purposes (Medical Packaging Paper) where the merged entity will have a [35-45 per cent] share of supply in Europe.  The number of recognised active players in this sector will reduce from three to two.

However, a large number of end-users of Medical Packaging Paper do not rely on steam sterilized paper.  In the event of a small but significant increase in the price of Medical Packaging Paper, they could use alternative materials such as flexible film.

Our investigation shows that those end-users, which are reliant wholly on steam sterilized paper, can expect the merged entity to be constrained by the ability of sack and kraft paper suppliers to quickly begin supplying paper for medical packaging purposes on a large scale.

Consequently, the OFT does not believe that it is or may be the case that the merger may be expected to result in a substantial lessening of competition within a market or markets in the UK.


This merger will therefore not be referred to the Competition Commission under section 33(1) of the Act.
