In order to ensure the middle layer in a face mask can effectively block up to 95% of airborne particles, the material requires the addition of a specific additive prior to the meltblown stage followed by a process known as electret charging. Charging only works when the correct additive solution is utilized, and together with the fiber denier, gram weight and number of layers, it ensures the middle layer of protective masks can effectively trap small airborne particles.

For brand owners seeking to maximize their rPET usage up to 100% to achieve sustainability and recyclability targets, Amosorb 4020R offers a cost effective solution with reliable oxygen scavenging performance and low haze levels on final bottles. For converters manufacturing bottles for oxygen sensitive beverages such as juices or teas and sauces, Amosorb 4020R is a unique masterbatch solution offering a reliable, cost effective oxygen scavenging performance, while giving freedom of usage for many different grades of rPET up to 100% in content.

Prevents condensation: Controlling the distribution, and so effectiveness, of anti-fog additives is easier than controlling the efficacy of a coating. PRODUCT BULLETIN KEY CHARACTERISTICS OnCap anti-fog additives maintain an excellent balance of immediate and long-lasting effects.

Mevopur™ Healthcare Colorants and Formulations Amber Colorants for Pharmaceutical Packaging Avient constantly monitors the evolution of regulations in the healthcare industry, and develops compliant products well before those regulations go into effect. Amber shades are known to offer effective protection from certain wavelengths, but the technologies of most amber polymer solutions on the market do not have regulatory support to comply with the pharmaceutical packaging regulations.

Amosorb 4020L offers an effective balance between bottle aesthetics, improved recyclability, and shelf life demands, by offering a cost-effective solution with reliable oxygen scavenging performance and rPET compatibility.

SPECIALTY PACKAGING SOLUTIONS ADD WEIGHT AND AESTHETICS TO YOUR LUXURY PACKAGING CLOSURE DESIGNS WITH DENSITY MODIFIED FORMULATIONS Consumers of luxury cosmetics and spirits tend to perceive added value from packaging that incorporates weight, aesthetics, and visual surface effects into the design. Injection-moldable Gravi-Tech™ density modified formulations can help you achieve the evenly distributed weight, complex designs, and visual surface effects of metal without the extra costs and steps associated with die cast mold tooling or secondary assembly operations. Add visual surface effects and aesthetics without complexity – You can achieve various aesthetic appearances using Gravi-Tech material such as color variation, metallic finish, or marbling and swirling.

Senior management believes these measures are useful to investors because they allow for comparison to Avient's performance in prior periods without the effect of items that, by their nature, tend to obscure Avient's operating results due to the potential variability across periods based on timing, frequency and magnitude. In addition, operating income before the effect of special items is a component of Avient's annual incentive plans and is used in debt covenant computations.
