1. Modern corrosion protection solutions with CLEAR PAK® 5000

Corrosion presents major challenges for companies in mechanical engineering, the automotive industry and metalworking. Moisture, temperature fluctuations and changing climatic conditions can attack unprotected metal parts and lead to rejects, reworking and additional costs. Reliable corrosion protection is therefore essential to protect components during production, storage and transport.

With CLEAR PAK® 5000 Ströbel offers a high-performance VCI solution for demanding industrial applications. The VCI film uses volatile corrosion inhibitors (VCIs), which provide their protective effect within the packaging. Particular advantages include the nitrite-free formulation, demand-based release of active agents and protection for a range of metals, including aluminium. This makes CLEAR PAK® 5000 a modern alternative to conventional corrosion protection methods such as oils or wax coatings.

2. What makes CLEAR PAK® 5000 special?

CLEAR PAK® 5000 combines reliable corrosion protection with a range of technical properties that offer particular advantages under demanding storage and transport conditions.
Nitrite-free formulation:CLEAR PAK® 5000 is completely nitrite-free. This distinguishes the film from VCI products that use nitrite-based active agents.

Protection for different metals, including aluminium: CLEAR PAK® 5000 has been developed to protect a variety of metals. In addition to ferrous metals and steel, aluminium, copper, brass and galvanised metals, among others, can also be protected.

Demand-based VCI release: The release of active agents responds to the prevailing environmental conditions. At higher levels of humidity, more inhibitor is released, while release is reduced under drier conditions. This ensures that the active agents are used according to requirements.

Warm parts can be packaged: Metal components can be packaged while still warm. This allows CLEAR PAK® 5000 to be easily integrated into existing production processes and can reduce additional waiting times.

Effective on both sides: The VCI effect works from both sides of the film. This gives CLEAR PAK® 5000 flexible options for converting and application.

Long-lasting protection: The optimised active-agent formulation reduces the loss of active agents during storage and the packaging process. This makes CLEAR PAK® 5000 particularly suitable for longer storage periods and demanding transport routes.

CLEAR PAK® 5000 RC with recycled content: CLEAR PAK® 5000 RC is also available as a version containing at least 30% recycled material. This allows companies to specifically use a VCI film with a defined proportion of recycled material.

3. CLEAR PAK® 5000 compared with previous VCI technologies

VCI films have become established as effective corrosion protection for industrial applications. CLEAR PAK® 5000 takes this technology further with a range of technical properties.

Nitrite-free VCI technology: CLEAR PAK® 5000 is completely nitrite-free. The formulation provides reliable corrosion protection without the use of nitrite-based active agents.

Optimised active-agent release: Compared with VCI systems that release active agents at a constant rate, CLEAR PAK® 5000 uses demand-based release of the corrosion inhibitors. The release adapts to changing environmental conditions, thereby supporting efficient use of the active agents.

Protection under demanding conditions: CLEAR PAK® 5000 has been developed for industrial applications in which components may be exposed to different temperature and humidity conditions. This makes the film particularly suitable for long-term storage and export packaging.

Tested properties and standards: CLEAR PAK® 5000 has undergone extensive testing and, according to the available product information, meets requirements including TRGS 615 and TRGS 900 as well as TL 8135-0043 Level 3. OEM certification is also available.

This makes CLEAR PAK® 5000 a high-performance solution for companies that value reliable corrosion protection, flexible application options and a nitrite-free formulation.

4. Areas of application

The combination of protection performance, multi-metal protection and flexible processing opens up numerous industrial applications for CLEAR PAK® 5000.

Mechanical engineering: Gearboxes, shafts, bearings and other metal engineering components can be reliably protected against corrosion during production, interim storage and transport.

Automotive industry: From bodywork parts and engine blocks to metal components and contacts, CLEAR PAK® 5000 is suitable for a wide range of applications in production and logistics.

Logistics & export: Changes in temperature, humidity and long transport times place particular demands on export packaging. CLEAR PAK® 5000 has also been developed for demanding storage and transport conditions.

Metalworking: Steel, aluminium, copper, brass and galvanised surfaces can be protected during various production and logistics stages.

Typical applications

CLEAR PAK® 5000 is suitable, among other applications, for the long-term storage of metal components, export and overseas packaging, interim storage within production processes and the protection of aluminium and steel components.

Another advantage of VCI technology: Components can be protected cleanly and dry. This can eliminate the need for time-consuming removal of oil or wax coatings before further processing.

5. Material, active agents and efficient application

In addition to corrosion protection itself, CLEAR PAK® 5000 offers specific properties that are of interest for modern industrial packaging processes.

At least 30% recycled material in CLEAR PAK® 5000 RC

For companies wishing to specifically use packaging material with recycled content, CLEAR PAK® 5000 RC is available with at least 30% recycled material.
The defined recycled content provides a clear and transparent basis for material selection.

Nitrite-free formulation

CLEAR PAK® 5000 does not use nitrite-based active agents. The VCI technology therefore provides an alternative to corrosion protection systems containing such active agents.

Demand-based use of active agents

The dynamic release of active agents ensures that the release of corrosion inhibitors adapts to the environmental conditions. Less active agent is released under drier conditions and correspondingly more at higher levels of humidity.
This reduces active-agent losses and ensures targeted use of the available corrosion inhibitors.

Less pre-treatment and post-treatment

Conventional corrosion protection methods using oils or wax coatings can require additional processing steps before components can be further processed.
VCI packaging, by contrast, provides dry corrosion protection, allowing appropriately protected components to be processed immediately after unpacking, provided no other cleaning is required.

6. Available versions and formats

CLEAR PAK® 5000 is available for different component sizes, packaging processes and industrial applications:

• Flat bags – for small to medium-sized components
• Side-gusseted bags – for larger or irregularly shaped parts
• Box covers – for machinery and bulky components
• Crate liners – for transport crates and mesh boxes.
• Stretch film and shrink film – for special applications
• VCI dispenser “Daubrite GT” – with CP5000 granulate for large protection volumes
• Custom-made solutions – such as perforated rolls or individually printed versions

This allows the VCI technology to be tailored to the product, packaging process and storage and transport requirements.

Background information: How VCI corrosion protection works

VCI stands for Volatile Corrosion Inhibitors. The active agents are released from the carrier material and disperse within the sealed packaging. At the metal surface, the VCI active agents provide protection against corrosion-promoting influences such as moisture and oxygen. This helps to protect metal components during storage and transport. A key advantage over oil- or wax-based methods is the clean and dry application. Additional coatings do not need to be applied and subsequently removed before further processing.

CLEAR PAK® 5000 also features optimised active-agent release: the release of the corrosion inhibitors responds to the prevailing environmental conditions. This ensures that the required protective effect is available particularly at higher levels of humidity.
