The non-GAAP financial measures include: adjusted EPS, adjusted operating income, free cash flow and adjusted EBITDA. Leading in Sustainability — PolyOne and Clariant are both founding members of the Alliance to End Plastic Waste, and we are committed to meeting the needs of the present without compromising the ability of future generations to do the same. In 2021 we expect substantial earnings growth and strong cash flow generation as we emerge from the COVID-19 pandemic.

Factors that could cause actual results to differ materially from those implied by these forward-looking statements include, but are not limited to: the time required to consummate the acquisitions; the satisfaction or waiver of conditions in the purchase agreements; any material adverse changes in Clariant's masterbatch business; the ability to consummate the acquisitions; our ability to achieve the strategic and other objectives relating to the acquisitions, including any expected synergies; our ability to successfully integrate Clariant's masterbatch business and achieve the expected results of the acquisitions, including, without limitation, the acquisitions being accretive; disruptions, uncertainty or volatility in the credit markets that could adversely impact the availability of credit already arranged and the availability and cost of credit in the future; the effect on foreign operations of currency fluctuations, tariffs and other political, economic and regulatory risks; the current and potential future impact of the COVID-19 pandemic on our business, results of operations, financial position or cash flows; changes in polymer consumption growth rates and laws and regulations regarding plastics in jurisdictions where we conduct business; fluctuations in raw material prices, quality and supply, and in energy prices and supply; production outages or material costs associated with scheduled or unscheduled maintenance programs; unanticipated developments that could occur with respect to contingencies such as litigation and environmental matters; an inability to achieve the anticipated financial benefit from initiatives related to acquisition and integration, working capital reductions, costs reductions and employee productivity goals; our ability to pay regular quarterly cash dividends and the amounts and timing of any future dividends; information systems failures and cyberattacks; and other factors affecting our business beyond our control, including, without limitation, changes in the general economy, changes in interest rates and changes in the rate of inflation.

Our testing has revealed that packaging made with Impress Colorants has no flow lines to disrupt the brilliant glossy surface. Our testing has shown that packaging manufactured with Impress does not have flow lines. With other metallic effect additives, these lines can appear on the surface of a polymer part where molten plastic flow fronts meet during processing.

Structural foam molding machines (Figure 1) are equipped with a plasticizing extruder and a separate transfer cylinder for quicker injection. Our experience has shown that the following adjustments are effective: • The gates and runners should be designed to achieve a quick and uniform filling of the mold • The melt flow should be directed from thin- walled to thick-walled sections • It is important for the mold to have good venting at the end of the flow path, in “dead-end” recesses and at the ejection pins The tooling strength for foam injection molds need not be as high as for solid injection molds as the internal pressure is now lower, due to the reduced viscosity of the base polymer, when the dissolved gases plasticize it. Typically, a weight reduction of 10–25% is achieved in parts with wall thicknesses >4 mm and short flow paths.
