As a supplier of Laboratory Corona Treaters, I am often asked about the types of materials that these versatile machines can effectively treat. Laboratory Corona Treaters are indispensable tools in various industries, offering a cost - effective and efficient way to modify the surface properties of different materials. In this blog, I will delve into the diverse range of materials that can be treated using a Laboratory Corona Treater.
Plastics
Plastics are one of the most common materials treated with a Laboratory Corona Treater. Polyethylene (PE) is a widely used plastic in packaging, automotive, and consumer goods industries. Untreated polyethylene has a low surface energy, which makes it difficult for inks, adhesives, and coatings to adhere properly. A Laboratory Corona Treater can significantly increase the surface energy of polyethylene films, improving their printability and adhesion properties.

Polypropylene (PP) is another plastic that benefits from corona treatment. Similar to polyethylene, polypropylene has a non - polar surface, resulting in poor adhesion characteristics. By subjecting polypropylene sheets or films to corona treatment, the surface is oxidized, creating polar functional groups. This enhances the wettability of the surface, allowing for better bonding with inks, paints, and adhesives.
Polystyrene (PS) is used in a variety of applications, such as disposable food containers and packaging materials. Corona treatment of polystyrene can improve its surface tension, making it more receptive to printing and coating processes. This is particularly important for branding and product identification purposes.
Films
Films, whether they are made of plastics or other materials, are frequently treated with Laboratory Corona Treaters. Biaxially Oriented Polypropylene (BOPP) films are commonly used in the packaging industry due to their high clarity, stiffness, and moisture resistance. However, their low surface energy can pose challenges in printing and laminating. Corona treatment of BOPP films modifies the surface, enabling high - quality printing and strong lamination bonds.
Polyester films, such as polyethylene terephthalate (PET), are widely used in applications like flexible packaging, electrical insulation, and photographic films. The smooth and inert surface of PET films can be difficult to bond with other materials. Corona treatment increases the surface roughness and introduces polar groups, improving the adhesion of coatings, adhesives, and metal layers.
Papers and Cardboards
Corona treatment is not limited to plastics and films; it can also be applied to papers and cardboards. In the printing and packaging industry, papers often need to be treated to enhance their printability. Untreated paper may have a non - uniform surface, which can lead to poor ink transfer and uneven print quality. A Laboratory Corona Treater can modify the paper surface, making it more receptive to inks and improving the overall print quality.
Cardboards used for packaging applications may require treatment to improve the adhesion of labels, coatings, or laminates. Corona treatment can increase the surface energy of cardboard, ensuring that labels stick firmly and coatings adhere evenly. This is especially important for high - end packaging where aesthetics and durability are crucial.
Metals
Metals can also be treated with a Laboratory Corona Treater. Aluminum foils are commonly used in the food packaging and electronics industries. The surface of aluminum foil can be passivated, which means it has a thin oxide layer that can affect its adhesion properties. Corona treatment can clean and activate the aluminum foil surface, improving the adhesion of coatings, adhesives, and printing inks.
Stainless steel is another metal that can benefit from corona treatment. In applications where stainless steel parts need to be bonded, painted, or coated, corona treatment can increase the surface energy and promote better adhesion. This is particularly useful in the automotive and aerospace industries, where strong bonds are essential for component performance.
Textiles
Textiles, including natural and synthetic fibers, can be treated with a Laboratory Corona Treater. Polyester and nylon fabrics are widely used in the fashion and technical textile industries. However, these synthetic fibers often have a smooth and hydrophobic surface, which can make it difficult for dyes and finishes to adhere. Corona treatment can increase the surface roughness and introduce polar groups on the fiber surface, improving the dyeability and the uptake of functional finishes.
Cotton, a natural fiber, can also be treated with corona treatment. In the textile finishing process, corona treatment can enhance the wettability of cotton fabrics, allowing for better penetration of dyes and chemicals. This can result in more vibrant colors and improved fabric performance.
Glass
Glass is a material with a high surface energy, but it can still benefit from corona treatment in certain applications. In the electronics industry, glass substrates are used for displays and touchscreens. Corona treatment can clean the glass surface and remove any organic contaminants. It can also modify the surface to improve the adhesion of thin - film coatings, such as indium tin oxide (ITO) used in touchscreen technology.
In the packaging industry, glass bottles and jars may be treated with corona treatment to improve the adhesion of labels. By increasing the surface energy of the glass, labels can stick more firmly, reducing the risk of label peeling during storage and transportation.
Composite Materials
Composite materials, which are made by combining two or more different materials, can also be treated with a Laboratory Corona Treater. For example, fiber - reinforced composites, such as carbon fiber - reinforced polymers (CFRP) and glass fiber - reinforced polymers (GFRP), are used in aerospace, automotive, and sports equipment industries. The surface of these composite materials can be treated to improve the adhesion between the fibers and the polymer matrix, as well as to enhance the bonding of additional layers or components.
Applications of Treated Materials
The treated materials mentioned above have a wide range of applications. In the packaging industry, treated plastics, films, papers, and cardboards are used to create attractive, functional, and durable packaging solutions. High - quality printing on treated surfaces can enhance brand visibility and product appeal.
In the automotive industry, treated metals, plastics, and composite materials are used for interior and exterior components. Strong adhesion of coatings and adhesives ensures the longevity and performance of these components.
In the electronics industry, treated glass, plastics, and metals are essential for the production of displays, printed circuit boards, and other electronic devices. Improved adhesion of thin - film coatings and soldering materials is crucial for the functionality of these devices.
