Macro Trends and Impact on Packaging Market Drivers Plastic Packaging Solutions • Concern for the environment • Light weight closures and neck finishes • Health and wellness • New closures for healthy beverages • Time pressure on consumers • Re-sealable/portable closures • Aging population • Lower removal torque • Safety & security • Consistent reliable tamper evidence • Cost and value effectiveness • Enhanced functionality/performance • Brand differentiation • Promotions and traceability • Enhanced/maintained flavor • Longer shelf-life Solutions for Better Packaging 3 ™®Trademark of The Dow Chemical Company (“Dow”) or an affiliated company of Dow

Innovation Examples: One-Piece PE Beverage Closures Driven by Performance… • Water has converted and is fully light weighted • CSD is converting and driving toward lighter weight • Hot Fill/Asceptic are converting Water: Light weighted CSD: Converting/Lt Wt. Hot Fill/Aseptic: Converting 4 ™®Trademark of The Dow Chemical Company (“Dow”) or an affiliated company of Dow

Bimodal Polyethylene Resins Offer… • Excellent Environmental Stress Crack Resistance (ESCR) of >100 hours*, enabling lightweighting while still helping to prevent cracking • Good processing characteristics with beneficial shear thinning behavior, making it suitable for high cavitation thin-wall molding processes • Minimum contribution to taste & odor (used in water applications today) • Bimodal HDPE Resins can be used to help eliminate cracking problems in current closures, or to enable lighter weight future closures without compromising performance 450 ESCR, F 50, 10% Igepal (hrs) • Bi-modal HDPE Resins are designed for closure applications where cracking can not be tolerated 400 350 300 250 392 200 150 100 50 0 6 8 DMDA-8007 (8 MI, 0. 965 D) DMDC-1210 (10 MI, 0. 952 D) CONTINUUM™ DMDA-1250 Uni-modal 8 MI/0. 965 D Uni-modal 10 MI/0. 952 D Bi-modal 1. 5 MI/0. 955 D (1. 5 MI, 0. 955 D) 5 ™®Trademark of The Dow Chemical Company (“Dow”) or an affiliated company of Dow

Objective of the Study Develop a PE resin technology that enhances the performance of beverage closures for aseptic and hot fill sterilization processes • Define key resin attributes • Show enhanced performance • Show enhanced benefits 6 ™®Trademark of The Dow Chemical Company (“Dow”) or an affiliated company of Dow

Innovation Around the Complexities of the Hot Fill Process Why choosing the right material is so important? Hot Fill 85 – 87° C Invert After Capping for Cap and Head Space Pasteurization, >80° C, 30 sec. In Asia Hot Shower 65° C, 10 min. = P Bottle Expansion by Hydrostatic Pressure Air Expansion Leads to Bottle Inflation Cool Down <40° C = P Cooling Effect leads to Volume Contraction – “Vacuum” 7 ™®Trademark of The Dow Chemical Company (“Dow”) or an affiliated company of Dow

Resin Attributes versus Application Resin Attributes Benefit for the Application High Flexural Modulus Stiffness High Heat Deflection Temperature High Vicat Softening Temperature Able to withstand the aseptic or hot fill process Good Environmental Stress Cracking Resistance (ESCR) Prevent over tighten caused crack Long-term performance Light weight Low Viscosity Easy process Low Removal Torque Easy to open Less or no slip needed 8 ™®Trademark of The Dow Chemical Company (“Dow”) or an affiliated company of Dow
