Web Cleaning for the Packaging Industry

Web cleaning is an essential but often underestimated process in the packaging production. It’s a key factor for making top-quality packaging and thus ensuring businesses can operate at their best level while guaranteeing the highest customer satisfaction.

In packaging, a pristine web isn’t just about appearance; it’s the bedrock of efficiency, cost-effectiveness, and client contentment. The process involves removing contaminants from the continuous material web as it navigates through the packaging production machinery. This critical step ensures that the web is free from dust, debris, ink residue, or other particles, crucial for maintaining flawless surfaces for high-quality packaging materials.

Utilizing cleaning technologies such as contact and non-contact techniques, web cleaning aims to minimize waste, bolster packaging quality, and heighten the overall efficiency of the packaging process.

Why is web cleaning important in the packaging industry?

The significance of web cleaning in packaging can’t be overstated. It’s pivotal in circumventing production blunders during packaging and converting processes.

Our top-tier web cleaning solutions proficiently cleanse high-speed webs like paper and packaging materials, minimizing particle-induced flaws in the packaging and substantially reducing rejection rates.

Benefits of implementing web cleaning in packaging encompass

Enhanced Productivity

Reduced downtime for maintenance amplifies operational efficiency, leading to financial gains.

Competitive Edge

Immaculate, quality packaging attracts more clients and lucrative business opportunities.

Sustainability

Decreased waste and energy-efficient methods not only cut costs but also bolster eco-friendly practices.

Cost Savings

Fewer rejected packaging materials and minimized waste equate to diminished production costs.

How web cleaning works in packaging

Web cleaning within packaging processes is a pivotal step that involves eliminating contaminants and residues from the continuous material web as it progresses through packaging production machinery. This process is fundamental to uphold a pristine web, ensuring top-notch packaging quality and mitigating defects.

Typically, non-contact web cleaning is employed in packaging production when processing wider material webs with delicate surfaces, like corrugated boards. This method ensures cleaning without direct physical contact with the most commonly used material surfaces like paper, solid or corrugated cardboard. Whereas film and foil are the most challenging materials for packaging production as they’re often used in highly demanding applications like food-, medical- or pharmaceutic production, where hygienic and legal prescriptions have to be met.


Key steps in the web cleaning process include:

Web cleaning is fundamental in packaging production, guaranteeing top-tier quality and minimizing defects caused by contaminants on the web.

Contaminant Detection

Contaminants such as dust, paper fibres or slitting particles are detected either visually or during quality control of the end product.

Strategic Placement

The cleaning mechanism is strategically positioned before the critical process, for example before winding or unwinding, slitting or cutting printing, ensuring a pristine web before further production or finishing processes.

Contaminant Disposal

Filter-Fan-Units collect and dispose of removed contaminants, employing suction or conveyors based on the dust load.

Monitoring and Maintenance

Real-time systems monitor efficiency, triggering maintenance if needed, ensuring proper function of cleaning elements and anti-static devices.

Quality Assurance

Quality control confirms a contaminant-free web ready for further finishing processes.

Two possible Cleaning Mechanisms

Contact Web Cleaning: Contact cleaning systems use cleaning elements such as adhesive rolls that directly engage with the moving web.

Non-contact Web Cleaning: Utilizing special ionizing air and suction blowers, non-contact technology, such as Kelva Cleanflow ®, dislodges contaminants without direct contact, safeguarding delicate materials.

Best products for web cleaning in packaging

Selecting the right web cleaning systems is critical for enhancing your packaging production and assuring the end product quality. Factors to weigh include the array of materials, material sensitivity, frequency of job changes, web width, speed, tension, and assessing the dust load at process interfaces and in your work environment. These considerations guide the choice of a tailored web cleaning solution, optimizing packaging operations for optimal efficiency and quality.

From the Kelva side, as experts in web cleaning in packaging, we suggest our line of non-contact web cleaners such as the Kelva BR-, TL/SL-, HS-, ST-series. Discover our selection of non-contact web cleaners on our product page.

Advantages of using Web Cleaning in the packaging industry

Not employing a web cleaning solution in the production process of packaging poses significant drawbacks. It results in compromised packaging quality due to contaminants like dust and residues, leading to rejected materials and increased waste. This neglect impacts equipment performance, causes operational inefficiency, and risks customer dissatisfaction.

Furthermore, implementing a web cleaning solution in your packaging process is also a financially sound investment. All the benefits will add up to a rapid return on invest.

The advantages of using web cleaning

  • Reduced wear on machinery parts like rollers and belts
  • Potential for significant reduction in cleaning cycles
  • Enhanced packaging quality by eliminating dust and debris
  • Minimized waste generation
  • Greater process stability with cleaner materials for packaging production
  • Diminished reliance on cleaning chemicals
  • Prolonged lifespan of equipment components
  • Streamlined setup during job changes due to a cleaner machine

What materials are commonly used in the packaging industry?

The packaging industry utilizes a diverse range of materials.

Paper and Cardboard

Commonly used for various packaging types, from boxes to cartons and labels.

Textiles

Fabrics such as cotton, jute, or canvas may be used for packaging, particularly in eco-friendly and reusable bags.

Film / Foil / Plastics

Including any kind of substrate for flexible packaging solutions in highly demanding industries.

Corrugated Board

Utilized for boxes and cartons, offering strength and durability.

Biodegradable and Eco-Friendly Materials

Increasingly popular for sustainable packaging options.

Suggested non-contact web cleaning models

BR45

KELVA BR Series

For web width up to 1400 mm, for film/foil applications.

TL1

KELVA SL/TL Series

For web width up to 2000 mm with special air handling options and ideal for higher dust loads.

HS85

KELVA TLX/HS/ST Series

For wide and very wide web width up to 10’000 mm and flexibly configurable to special applications and high dust loads like in corrugated and tissue production.

In summary, there aren’t any inherent differences in web cleaning for packaging compared to other industries, such as printing. Packaging involves a diverse array of materials, from cardboard and paper to film and foil, necessitating adaptable cleaning methods to handle varied surfaces effectively, for example before laminating and further delicate finishing processes.

The cleaning process is similar in a packaging production line as it is in a printing line. Unique challenges in packaging specifically arise when packaging food, medical or pharmaceutical items because of the legal prescriptions and high demand for hygiene.
