Why Choose 33×45mm Preformed PVC Shrink Caps?

• Preformed construction arrives ready to apply with no preparation needed, saving time and reducing handling steps compared to lay-flat shrink sleeves
• PVC material shrinks cleanly and consistently under heat gun or heat tunnel application, delivering a tight, professional finish across every bottle
• Two versatile finish options — matte black and clear/transparent — suit a wide range of label and packaging designs without overpowering bottle aesthetics
• Tamper-evident seal communicates product integrity to consumers and meets standard bottling presentation expectations across spirits, food, and beverage categories
• 33mm diameter fits bottle necks and stoppers up to 32mm, bridging the gap between the 31mm and 36mm shrink cap sizes for bottle formats that fall between standard neck widths
• Sizing guidance recommends ordering a cap 1-2mm larger than the widest point of the stopper or neck for a consistent, snug fit every time

33×45mm preformed PVC shrink caps outperform lay-flat shrink sleeves for producers bottling with mid-range neck formats, arriving ready to apply straight from the carton and delivering consistent heat-shrink performance across matte and clear finishes that keep the focus on the bottle and its contents.
