Closure Details

The Extra-Lok V 38mm ODU unique “Triple Seal” closure liner geometry securely seals both PET and HDPE bottles despite finish distortion that can be inherent with hot-fill applications. The light-weight design also offers application efficiency, reducing the total cost of operations.

Lightweight “Universal” Design

• 38mm, 2-piece / lined, double lead thread, HDPE closure
• 18%+ lighter than competitive 38mm 2-pc designs
• “Triple Seal” design securely seals PET and HDPE
• Compatible with 1843, 1845 and similar PET bottle finishes (0.060” –0.100” finish wall thickness)
• Compatible with 1842 and similar HDPE bottle finishes
• Other finish wall thicknesses considered on a case-by-case basis
• Early pressure release results in longer thread engagement after venting for maximum anti-blow-off security
• Secure tamper evidence for product and consumer safety
• Consumer-friendly, consistent removal torques
• Debossing, top printing, UTC promo and color options for enhanced brand marketability

Reduces Total Cost of Operations

• Broad application window and robust performance
• Universal seal geometry helps minimize finish distortion inherent with hot-fill PET bottles
• Molded-in liner for maximum flexibility, accommodating plastic bottle finish variability
• Less maintenance, more productivity
• Energy saving, no steam application for improved capping efficiency
• In addition to quality closures, CSI provides capping equipment and technical services, globally.
