DS Smith’s UK Restructuring Signals a Major Shift in Packaging and Paper Manufacturing Strategy

Packaging and paper giant DS Smith is advancing a significant restructuring of its UK manufacturing footprint, with proposed and confirmed changes at facilities including Launceston in Cornwall and Kemsley in Kent. The developments point to a broader effort to align production capacity, improve manufacturing efficiency and concentrate investment on strategically important assets.

The most immediate impact will be felt at DS Smith’s Launceston box plant, where production is expected to cease in November following an employee consultation. The closure will affect approximately 165 jobs, making it a significant industrial and economic development for the Cornish community.

DS Smith described the decision as difficult and said it followed careful consideration of counter-proposals put forward during the consultation process. The company also acknowledged the wider consequences for employees, their families and the local community and said it would provide support to affected workers.

Launceston closure: more than a capacity reduction

The Launceston facility has been part of the local industrial landscape for almost six decades. Its closure therefore represents more than the loss of a manufacturing site: it removes a long-standing source of employment, skills and economic activity from the area.

Workers and their families publicly opposed the closure proposal in June, highlighting the importance of the plant to Launceston. The eventual decision demonstrates the difficult balance manufacturers face between maintaining local production and responding to changing cost, demand and network requirements.

For DS Smith, the decision is likely to be viewed within the context of its wider UK manufacturing network rather than as an isolated site-level action. Packaging production is increasingly influenced by transportation costs, customer proximity, plant utilisation, energy prices, labour availability and the ability to operate equipment at competitive scale.

The closure could therefore result in production being redistributed across other facilities, depending on customer requirements and available capacity. For customers, such changes can create both opportunities and challenges, particularly around lead times, logistics and supply-chain resilience.

Kemsley: closing PM4 while investing in PM6

The proposed changes at Kemsley paper mill in Kent illustrate a different element of DS Smith's strategy.

Rather than simply reducing capacity, the company is proposing to close Paper Machine 4 (PM4) while investing in Paper Machine 6 (PM6). This distinction is strategically important.

Modernising or concentrating production on more competitive assets can allow a paper producer to reduce exposure to older or less efficient machinery while directing capital towards equipment with stronger long-term economics.

For an integrated packaging business such as DS Smith, paper-machine strategy has implications well beyond the mill itself. Containerboard and other paper grades form a critical part of the company's packaging supply chain. Improving the competitiveness and reliability of key paper assets can therefore strengthen the downstream packaging operation.

The Kemsley proposal should consequently be seen as a portfolio optimisation measure, rather than simply a reduction in manufacturing capacity.

A broader restructuring of the UK network

The latest developments are consistent with a pattern of restructuring across DS Smith's UK operations.

The company previously announced restructuring at its Louth site in Lincolnshire, where 70 positions were made redundant in 2024. During 2025, consultations at facilities in Plymouth, Derbyshire, Newcastle, Sheerness and Wellingborough resulted in decisions to close those sites.

Taken together, these developments indicate that DS Smith has been reassessing the configuration of its UK manufacturing network over several years.

The underlying question for the business is not simply how much capacity it operates, but where that capacity should be located and what type of assets should receive investment.

Why the UK paper and packaging sector is restructuring

The developments also reflect structural pressures facing the wider paper and packaging industry.

1. Energy and manufacturing costs

Paper manufacturing is particularly energy-intensive. Electricity, gas, steam and other utilities can represent a substantial component of production costs. Mills operating older equipment or at lower utilisation can therefore become increasingly difficult to justify economically when energy and other input costs rise.

2. Asset productivity

Paper machines and packaging plants require substantial capital investment. Operators increasingly need to concentrate capital expenditure on assets capable of delivering competitive production costs, higher reliability and products aligned with future customer demand.

The proposed PM4 closure and PM6 investment at Kemsley is a clear example of this approach.

3. Changing packaging demand

The packaging sector continues to evolve as customers respond to sustainability requirements, e-commerce, retail changes and efforts to reduce packaging materials.

Demand growth does not automatically benefit every plant equally. Product mix, machine capability and geographical location increasingly determine which facilities are best positioned to capture future demand.

4. Network efficiency

Operating a large manufacturing network creates fixed costs and logistical complexity. Where multiple plants serve overlapping markets, companies may seek to consolidate production into fewer, better-utilised facilities.

Such decisions can improve overall network economics but can also increase transportation distances and create regional employment impacts.

What the changes mean for DS Smith

From a strategic perspective, the restructuring appears to have three interconnected objectives: simplification, productivity and targeted investment.

The Launceston closure reduces the company's physical manufacturing footprint, while the Kemsley proposal would concentrate papermaking activity on a selected machine and direct investment towards PM6.

This is characteristic of a mature manufacturing business seeking to improve returns from its industrial asset base.

However, restructuring also involves risks.

Consolidating production can place greater operational dependence on remaining facilities. Any significant outage, maintenance issue or unexpected demand increase at a key plant could have a larger impact if spare capacity across the network is reduced.

There are also customer-service considerations. Packaging customers typically place considerable value on reliable delivery, consistent quality and supply continuity. Any network transition must therefore be carefully managed to prevent disruption.

The human and regional cost

The economic logic of restructuring does not eliminate its social consequences.

The loss of 165 jobs at Launceston will have an impact beyond the individuals directly employed at the plant. Local suppliers, contractors, service businesses and households can also experience secondary effects when a major industrial employer leaves a community.

For towns with long manufacturing histories, plant closures can also mean the loss of specialised skills and institutional knowledge that have accumulated over decades.

DS Smith's commitment to supporting affected employees will therefore be an important part of the closure process, particularly around redundancy arrangements, retraining and employment assistance.

A sign of where UK manufacturing is heading

The DS Smith developments provide a useful case study of the pressures facing UK paper and packaging manufacturing.

The direction of travel is increasingly towards fewer but more productive assets, greater automation, improved machine efficiency and investment in facilities that are considered strategically competitive.

For manufacturers, maintaining every existing site is becoming increasingly difficult when production costs, customer requirements and capital demands are changing rapidly.

For policymakers and local communities, however, the developments raise a different question: how can the UK retain a competitive manufacturing base while managing the social and regional consequences of industrial consolidation?

Outlook

The Launceston closure is now moving towards implementation, with production expected to end in November. At Kemsley, the proposed PM4 closure and PM6 investment remain part of the company's restructuring process and demonstrate the different approaches being taken across the network.

The immediate focus will be on managing employee transitions and maintaining customer supply during the changes. Longer term, the success of the restructuring will depend on whether DS Smith can generate sufficient efficiency and competitiveness from its remaining UK manufacturing assets to offset the capacity and regional footprint being removed.

For the UK paper and packaging industry, the message is significant: capacity is not simply disappearing—it is being selectively reshaped around assets, locations and technologies that manufacturers believe can remain competitive in the next phase of the market.
