Innovation meets responsibility: CLEAR PAK® 5000 XR

With CLEAR PAK® 5000, DaubertCromwell demonstrates how modern VCI technology and downgauged PE films work together perfectly. This VCI film (volatile corrosion inhibitors) actively protects metal components against corrosion by releasing vapor-phase protection molecules that form an invisible protective layer on the metal surface.

💡 Key features:

• Dynamic inhibitor release: automatically adapts to ambient humidity.
• 100% nitrite-free and safe: non-hazardous to health, compliant with regulations, sustainable.
• Effective on both sides: even protection on both sides.
• Recyclable: also available as CLEAR PAK® 5000 RC with at least 30% recycled content.
• Suitable for warm parts: can be used directly after production.

The result is a packaging solution that provides effective corrosion protection while actively contributing to resource conservation.

🧩 The general benefits of thickness-reduced PE films in general

1) Material and cost savings

• Up to 30% less material usage per square metre.
• Reduced transport costs thanks to lower weight.
• Significantly lower energy consumption in production.

2) Sustainability and recycling

• Fewer fossil raw materials required.
• Improved CO₂ footprint over the entire product life cycle.
• Fully recyclable – especially mono-material films made of PE.

3) Technical stability

• High tear and puncture resistance.
• Stable seal seams for automated packaging processes.
• Same performance despite reduced thickness.

4) Energy efficiency

• Thinner films mean shorter extrusion times.
• Lower melt volumes save energy during transport and storage.

⚙️ Typical fields of application

• Metalworking and mechanical engineering
• Automotive and supplier industry
• Logistics and export packaging
• Food industry (e.g. cover and cling films)

Especially in industrial environments where components react sensitively to humidity, temperature and transport conditions, the combination of thickness-reduced PE film and VCI technology offers enormous benefits.

👉 Note: The technology of thickness-reduced PE film is not limited to the VCI sector.
Ströbel can also implement these sustainable film solutions for other PE film types – such as ESD films, transparent LDPE films or composite materials. This means that users outside corrosion protection also benefit from the ecological and economic advantages of this innovative material optimization.

Case study: Sustainable corrosion protection in metal processing

A metalworking company from southern Germany was facing a familiar challenge:
High-precision components made of steel and aluminium had to be transported over several weeks and stored in changing climate zones – without any corrosion and with as little packaging material as possible.

Up to now, conventional VCI films and oil-based protective coatings had been used. These resulted in:

• high consumption of materials,
• time-consuming cleaning of the parts before further processing,
• as well as rising disposal and energy costs.

In close collaboration with Ströbel, the company opted for the reduced-gauge VCI film CLEAR PAK® 5000 XR. Implementation was carried out step by step, starting with the packaging of components for overseas transport.

After only a short time, it became clear:

• The double-sided protective effect ensured uniform corrosion protection, even at high humidity.
• The reduced film thickness made it possible to cut material consumption by almost 30%.
• The lower weight led to reduced disposal costs and a CO₂ saving of several hundred kilograms per year.
• Thanks to its suitability for warm components, packaging time in production was significantly reduced.

The decisive advantage:
Since the changeover, no corrosion damage has occurred – neither during storage nor during transport. Switching to reduced-gauge VCI film has therefore not only delivered measurable ecological and economic benefits, but has also improved process reliability and customer acceptance.

🧾 Conclusion: Thickness-reduced PE films

…are more than just a trend – they are the future of packaging.
In combination with innovative solutions such as CLEAR PAK® 5000 XR they demonstrate that sustainability, functionality and cost efficiency fit together perfectly.

Whether in mechanical engineering, the automotive industry or international export – less material with the same protective performance is the key to a more efficient, more environmentally friendly future.

With CLEAR PAK® 5000 XR, Ströbel consistently puts this commitment into practice – for packaging that protects, saves and delivers sustainable performance.
