Packaging Line Lock-In  

1. Introduction

Packaging Line Lock-In refers to a situation in which a supplier of packaging machinery or an integrated packaging production line makes customers so dependent on its equipment, software, consumables, spare parts, technical services, maintenance systems, or proprietary specifications that switching to a competing supplier becomes difficult, costly, or commercially impractical.

The issue becomes a competition-law concern particularly where a firm with substantial or dominant market power uses the installed base of packaging lines to restrict competition in related markets.

Typical examples include:

• requiring customers using a packaging machine to purchase packaging material from the machine manufacturer;
• restricting the use of third-party cartons, bottles, films, caps or labels;
• proprietary machine software that prevents third-party components from operating;
• exclusive maintenance or servicing requirements;
• refusal to provide spare parts, technical specifications or interfaces;
• tying machinery to consumables;
• loyalty rebates linked to purchasing the entire packaging line from one supplier;
• long-term exclusive supply arrangements;
• contractual warranties that become void when third-party inputs are used;
• technical certification systems that unnecessarily exclude rival suppliers;
• withholding interoperability information;
• making replacement equipment compatible only with the incumbent's consumables.

The classic example is Tetra Pak, where packaging machinery and packaging materials were treated as closely connected markets and restrictions on the use or purchase of competing packaging materials were examined as exclusionary conduct.

2. Meaning of Lock-In

Lock-in exists when a customer has already invested heavily in a particular system and therefore faces significant switching costs.

For a packaging line, switching costs can include:

1. Capital costs — replacement of machinery.
2. Downtime costs — stopping production to install another system.
3. Training costs — retraining operators and technicians.
4. Compatibility costs — adapting bottles, cartons, caps, labels or films.
5. Software costs — replacing proprietary control systems.
6. Validation costs — re-certification of food, pharmaceutical or medical packaging.
7. Maintenance costs — dependence upon the original manufacturer's service network.
8. Spare-parts dependence — proprietary components unavailable from independent suppliers.
9. Contractual costs — termination penalties or loss of rebates.
10. Data and interoperability costs — inability to transfer machine settings, production data or recipes.

Lock-in itself is not automatically unlawful. Competition law becomes relevant when the lock-in is deliberately created or exploited by a firm possessing substantial market power and the conduct has exclusionary effects.

3. Relevant Markets

A packaging-line lock-in investigation may involve several interconnected markets.

A. Primary equipment market

For example:

• aseptic filling machines;
• bottling machines;
• carton filling machines;
• canning equipment;
• labeling machines;
• wrapping machinery;
• pharmaceutical packaging lines.

B. Aftermarkets

Separate markets may exist for:

• spare parts;
• maintenance;
• software;
• technical services;
• upgrades;
• replacement components.

C. Consumables market

Examples:

• cartons;
• films;
• caps;
• labels;
• closures;
• specialized packaging material.

D. Integrated production-line market

A complete line may contain:

processing equipment → filling equipment → packaging equipment → inspection → labeling → palletization → software/control system.

The competition-law question is whether these products constitute one integrated market or whether economically distinct aftermarkets exist.

4. Main Competition Concerns

A. Tying

The strongest concern arises where a dominant packaging-equipment supplier says:

"If you purchase our packaging machine, you must also purchase our packaging material."

For example:

Packaging machine + proprietary carton

or

Filling machine + proprietary caps

or

Packaging line + compulsory maintenance software

If the machinery and consumable are distinct products and the supplier possesses substantial power in the machinery market, the arrangement may foreclose competing suppliers of the tied product.

This was central to the Tetra Pak litigation.

5. Exclusive Dealing

A supplier may require the customer to purchase all or most of its packaging requirements from the supplier.

Example:

A beverage producer purchasing a packaging line must obtain 90–100% of its cartons from the machinery supplier for ten years.

Such an arrangement may prevent rival carton suppliers from obtaining sufficient demand to compete.

The competitive concern increases where:

• the supplier has a large installed base;
• contracts are long-term;
• switching costs are high;
• customers represent a substantial portion of demand;
• competitors cannot readily reach alternative customers.

6. Spare-Parts Lock-In

A machinery manufacturer may attempt to control the aftermarket by supplying:

• proprietary sensors;
• PLC components;
• machine-specific valves;
• proprietary nozzles;
• replacement heads;
• electronic control boards.

If independent maintenance providers cannot obtain necessary components, customers may become dependent upon the original equipment manufacturer.

Competition authorities may therefore examine whether the restriction is:

• technically necessary;
• objectively justified;
• proportionate;
• necessary for safety;
• necessary for warranty protection; or
• primarily intended to exclude independent suppliers.

7. Software and Interoperability Lock-In

Modern packaging lines increasingly rely upon:

• PLC systems;
• SCADA;
• MES;
• cloud monitoring;
• predictive-maintenance software;
• machine-learning systems;
• digital twins.

A supplier may create lock-in by preventing rival machinery or components from communicating with its control platform.

For example:

Packaging Line A will operate only with Supplier A's certified filling valves because the control software refuses to recognize third-party components.

The competition issue becomes particularly important when the software interface is technically capable of supporting competing components but access is artificially restricted.

8. Warranty-Based Lock-In

Another common technique is:

"Warranty becomes invalid if the customer uses third-party packaging material."

Such a clause is not automatically unlawful.

The supplier may have legitimate concerns relating to:

• machine damage;
• food safety;
• contamination;
• technical compatibility;
• product liability.

However, competition concerns can arise if the warranty restriction is used as a mechanism to eliminate otherwise viable competitors.

A less restrictive solution may be:

third-party products are permitted provided they satisfy objectively defined technical specifications.

9. The Tetra Pak Principle

Tetra Pak International SA v Commission

Case T-83/91; Case C-333/94 P

This is the most important authority for packaging-line lock-in.

Tetra Pak operated in packaging machinery and packaging materials. The Commission found that Tetra Pak's contractual practices included restrictions concerning the supply and use of packaging materials with its machines.

The EU courts upheld the essential competition-law findings.

The case demonstrated that a dominant undertaking cannot necessarily use its position in a packaging-equipment system to eliminate competition in a closely connected packaging-material market.

The importance of the case lies in the recognition that:

equipment and consumables can constitute economically distinct products even where they are technically interconnected.

The fact that a machine and its consumables work together does not automatically justify exclusive sourcing.

The Tetra Pak litigation also emphasized the significance of:

• market power;
• contractual dependence;
• entry barriers;
• technical compatibility;
• exclusivity;
• foreclosure of competing packaging-material suppliers.

The Court of First Instance noted the significance of contractual arrangements that could make customers dependent upon Tetra Pak for the entire life of the machine.

10. Tetra Pak / Alfa-Laval

Commission Decision — Tetra Pak/Alfa-Laval

The Commission's examination of the Tetra Pak/Alfa-Laval transaction is another important packaging-sector authority.

The Commission considered the relationship between:

• packaging machinery;
• processing machinery;
• aseptic cartons; and
• related technologies.

The case illustrates how an integrated packaging-line supplier may obtain additional competitive advantages from controlling neighboring stages of production.

However, the Commission also examined whether the technical and commercial relationship between the different machines was sufficiently strong to create additional foreclosure effects.

The lesson is important:

Vertical integration is not itself unlawful; the question is whether integration gives the firm an ability and incentive to foreclose competitors.

The Commission identified significant entry barriers in aseptic packaging machinery, including technological and intellectual-property barriers.

11. Tetra Pak — China

Tetra Pak — SAIC/China

The Chinese Tetra Pak enforcement decision is particularly relevant to modern packaging-line lock-in.

Chinese authorities examined Tetra Pak's conduct concerning:

• packaging equipment;
• technical services;
• packaging materials;
• exclusive arrangements;
• loyalty discounts.

The authorities concluded that Tetra Pak had used its market position to impose restrictions concerning packaging materials and thereby affect competition in the packaging-material market.

The conduct included restrictions requiring customers using Tetra Pak equipment to use Tetra Pak or approved packaging materials in specified circumstances.

The Chinese enforcement analysis treated the equipment and packaging materials as sufficiently distinct products for tying analysis.

The case is therefore highly relevant to a modern packaging-line lock-in scenario.

12. Tomra Systems ASA v European Commission

Case C-549/10 P

Although Tomra concerned machines for collecting used beverage containers, rather than conventional packaging lines, it is highly relevant to equipment lock-in.

Tomra supplied reverse-vending machines and entered into:

• exclusivity arrangements;
• quantity commitments;
• loyalty-rebate arrangements.

The EU courts upheld the finding that the arrangements could foreclose competitors from the relevant equipment markets.

The case demonstrates that lock-in can be created contractually rather than technologically.

For packaging equipment, the equivalent could be:

packaging-line supplier + exclusive purchase requirement + long contract duration.

The Court confirmed the relevance of foreclosure and the structure of competition rather than merely examining whether customers formally agreed to an express "exclusive" clause.

13. Hilti AG v Commission

Cases T-30/89 and C-53/92 P

Hilti concerned nail guns, cartridges and nails.

Although it was not a packaging case, it provides a powerful analogy for packaging-line lock-in.

Hilti possessed substantial power concerning nail guns and was found to have engaged in conduct involving related products, including tying and restrictions affecting competing consumables.

The fundamental competition-law lesson is:

A supplier with market power in a primary equipment product cannot automatically use that power to control competition in complementary consumables.

The analogy is particularly strong where a packaging-machine supplier attempts to force customers to buy:

• cartons;
• labels;
• caps;
• film;
• adhesives; or
• other consumables

only from itself.

14. Microsoft Corp. v Commission

Case T-201/04

Microsoft concerned the relationship between a dominant operating system and a separate media-player product.

The General Court upheld findings concerning Microsoft's tying conduct.

Although software rather than packaging machinery was involved, the case is useful because it addresses the broader concept of leveraging power from one product into another product.

Applied to packaging lines:

A supplier with substantial power over packaging-line control software may potentially use that position to disadvantage competing equipment or consumables.

The case therefore provides an important framework for analyzing digital lock-in in modern Industry 4.0 packaging systems.

15. Bronner v Mediaprint

Case C-7/97

Bronner concerns refusal of access to an infrastructure/service system.

The Court established demanding conditions for requiring a dominant undertaking to provide access to an alleged essential facility.

The principles are relevant where a packaging-line supplier controls something that competitors allegedly need to access, such as:

• proprietary software interfaces;
• technical specifications;
• machine communication protocols;
• essential diagnostic systems;
• proprietary replacement components.

However, mere usefulness is insufficient. The facility must satisfy stringent requirements concerning indispensability, elimination of competition and lack of objective justification.

Thus, a packaging-equipment supplier does not automatically have to open every proprietary interface to competitors.

16. Slovak Telekom v Commission

Joined Cases C-152/19 P and C-165/19 P

Slovak Telekom concerns access to telecommunications infrastructure and the interaction between regulated access obligations and Article 102 TFEU.

Its broader significance for packaging-line lock-in is the distinction between:

• an independently imposed refusal to provide access; and
• conduct governed by a regulatory access obligation.

The principle can be useful where packaging infrastructure is subject to sector-specific safety, technical or interoperability regulation.

It also demonstrates why competition authorities distinguish between ordinary proprietary systems and infrastructure where access obligations already exist.

17. Summary of the Six Major Authorities

18. When Packaging Line Lock-In Becomes Problematic

A competition authority is more likely to scrutinize the conduct where several factors exist simultaneously:

1. Significant market power

The supplier has a substantial share of the packaging-equipment market and competitors face high entry barriers.

2. High switching costs

Replacing the entire production line would be extremely expensive.

3. Long equipment life

Packaging machinery may remain operational for many years, creating durable customer dependence.

4. Proprietary consumables

The machine is technically configured to accept only the supplier's consumables.

5. Contractual exclusivity

Customers are prohibited from purchasing competing products.

6. Technical restrictions

Third-party products are deliberately prevented from operating.

7. Limited interoperability

The supplier refuses to provide necessary technical interfaces without legitimate justification.

8. Foreclosure

Competitors lose access to a substantial portion of the downstream market.

9. Lack of objective justification

The supplier cannot establish genuine safety, quality, technical or regulatory reasons.

10. Strategic use of installed base

The supplier exploits an existing installed base to extend dominance into adjacent markets.

19. Legitimate Lock-In Versus Anti-Competitive Lock-In

Not every lock-in arrangement violates competition law.

The central question is therefore not:

"Does the packaging system create dependence?"

but rather:

"Is the dependence an ordinary consequence of efficient product design, or is substantial market power being used to exclude competing suppliers?"

20. Economic Effects

Packaging-line lock-in can produce several effects.

A. Foreclosure of competitors

Competing consumable suppliers cannot access customers operating the incumbent's machines.

B. Higher prices

Once customers are locked in, the supplier may have greater ability to raise prices for consumables and maintenance.

C. Reduced innovation

Rival suppliers may have insufficient demand to develop alternative products.

D. Increased entry barriers

Potential entrants must overcome both technical and commercial barriers.

E. Reduced customer choice

Customers may be unable to switch individual components without replacing the entire production line.

F. Aftermarket exploitation

The supplier may charge higher prices for:

• spare parts;
• software licences;
• maintenance;
• upgrades;
• consumables.

21. Competition-Law Test

A useful analytical sequence is:

Step 1 — Identify the relevant market

↓

Step 2 — Determine market power

↓

Step 3 — Identify the locked-in component

Machine / software / consumable / spare part / service

↓

Step 4 — Determine whether products are distinct

Could customers reasonably purchase the machine and consumable separately?

↓

Step 5 — Identify the mechanism of lock-in

Tying / exclusivity / technical restriction / refusal to supply / rebates / interoperability restriction

↓

Step 6 — Examine foreclosure

Can competitors realistically reach customers?

↓

Step 7 — Assess switching costs

How difficult is it to change suppliers?

↓

Step 8 — Examine objective justification

Safety / quality / technical compatibility / regulation / IP protection

↓

Step 9 — Apply proportionality

Is the restriction necessary and appropriately limited?

↓

Step 10 — Assess competitive effects

Price / innovation / entry / consumer choice / quality.

22. Defences Available to the Supplier

A packaging-line manufacturer may argue that the restriction is necessary because of:

A. Food safety

Particularly relevant to aseptic packaging and food-contact materials.

B. Pharmaceutical safety

Packaging systems may require validated components.

C. Technical compatibility

Third-party materials may genuinely damage machinery.

D. Product liability

The manufacturer may need to control components affecting product safety.

E. Quality assurance

Uniform materials may be necessary for consistent production.

F. Intellectual-property protection

Certain interfaces or technologies may legitimately be protected.

G. Warranty protection

The manufacturer may restrict third-party products that genuinely create abnormal risks.

However, the Tetra Pak line of authority shows that technical or health-related arguments cannot simply be asserted; the restriction should be appropriately connected to the legitimate objective and proportionate to it.

23. Remedies

Where unlawful packaging-line lock-in is established, possible remedies include:

1. termination of exclusivity provisions;
2. removal of tying clauses;
3. permitting qualified third-party consumables;
4. publication of objective technical specifications;
5. interoperability obligations;
6. access to necessary interfaces;
7. availability of spare parts;
8. modification of warranty provisions;
9. prohibition of discriminatory certification;
10. behavioural commitments;
11. structural remedies in exceptional cases;
12. monetary penalties.

Tetra Pak's earlier commitments, for example, included removing elements of contractual exclusivity and allowing customers greater freedom to purchase packaging material from other suppliers.

24. Conclusion

Packaging Line Lock-In sits at the intersection of tying, exclusive dealing, aftermarket power, refusal of access, interoperability and abuse of dominance.

The most important authority is Tetra Pak, because the dispute directly concerned the relationship between packaging machinery and packaging materials. The case demonstrates that technical compatibility between equipment and consumables does not automatically justify exclusive sourcing.

The broader authorities—Hilti, Tomra, Microsoft, Bronner and Slovak Telekom—provide complementary principles concerning complementary products, equipment-based foreclosure, platform leverage, access and interoperability.

A legally significant packaging-line lock-in case will therefore generally turn on five questions:

Market power + distinct products + restrictive mechanism + foreclosure + absence of adequate objective justification.

Where these elements combine, an apparently ordinary packaging-equipment contract can become a significant competition-law issue, particularly when the installed base of machines is used to control downstream consumables, maintenance, software or spare-parts markets.
