Description
33×45mm preformed PVC shrink caps are tamper-evident bottle closure caps made from durable PVC material, designed to slip over a sealed bottle neck and shrink to a clean, professional finish with the application of heat. Each cap arrives fully preformed and ready to apply — no opening or preparation required before placing on the bottle, unlike lay-flat shrink sleeves that must be manually opened prior to use. Applied using a heat gun or heat tunnel, the PVC material conforms tightly to the bottle neck and stopper, creating a secure tamper-evident seal that reassures consumers and reinforces brand presentation at the point of sale. Available in matte black and clear/transparent, each finish offering a distinct look to complement a wide range of label and packaging designs. Pre-shrink diameter is 33mm with a 45mm height, designed to fit bottle necks and stoppers up to 32mm at their widest point. Perfect for distilleries, wineries, hot sauce manufacturers, maple syrup bottlers, specialty food producers, and any operation seeking a reliable tamper-evident seal across small-batch and high-volume bottling operations alike.
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.
