Plasma treatment modifies material surfaces to enhance bonding capabilities. By generating ionized gas, it interacts at the microscopic level, increasing surface energy and improving adhesion, wettability, and bonding with coatings, adhesives, and inks. This versatile process is utilized across industries such as automotive, aerospace, electronics, and medical devices to boost material performance without altering inherent properties, effectively treating plastics, metals, gl

The increased use of U.V. and waterbased inks, in conjunction with polyethylene and polypropylene is making corona treating a vital part of the converting process. As a result, corona treater manufacturers have been challenged to advance the state of technology to meet the increasing demands resulting from the expanding use of corona treaters. ​ Recent developments in corona treating designs have reflected the influence of the expanded role of corona treating in converting wi

The increased demand for corona treater products is apparent by the greater volume of materials being handled by plastics processors and the growing number of applications. The trend is for even greater reliance upon corona treating to prepare increasing amounts of film and foil webs for printing, gluing and other converting steps that require a surface that will readily accept inks or adhesives. This is true for both materials currently in use as well as for new materials un

A typical corona treatment system is designed to produce a corona in the air gap between the high voltage electrode and the ground roller. Corona will be produced anywhere there is air within this gap. ​ The occurrence known as “backside treat” is the result of a corona being produced on both sides of the web even though the treating system is only intended to treat one side. The resulting undesired treatment on the backside of the web can result in blocking and picking. It m

The purpose of this presentation is to discuss the surface tension phenomenon and give some insight into why many flexographic printers are finding the need to add surface treatment equipment to their presses. ​ The trend toward converting to waterbased inks has forced the flexographic printer to become familiar with many new sciences, procedures, and processes in order to achieve the final product. Once the responsibility of the film supplier, flexographic printers are findi

There are two different types of treater stations, one designed to treat conductive substrates, now known as bare roll, and the other designed to treat non-conductive substrates, known as covered roll. The primary difference between these designs is the location of the dielectric material, and the method used to cool the dielectric. Conductive vs. Non-Conductive Treatment Methods Conductive or metallized substrates require the dielectric to be on the "hot" electrode, so the h

Although UV and waterbased inks have been used in narrow web printing for some time now, the use of PP, LDPE and metallized substrates have recently become more common. As a result, the need for corona treating equipment on narrow web presses has increased, presenting manufacturers with a series of design challenges. Similarly, corona treaters have been used on narrow web presses for years but have traditionally been used to assure even treat on pretreated material, requiring
