Description

31×45mm preformed PVC shrink caps are tamper-evident bottle closures made from durable PVC material, designed to slip over a sealed bottle neck and shrink for 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 gold, matte black, and clear/transparent, each option offering a distinct finish to complement a wide range of label and packaging designs. Pre-shrink diameter is 31mm with a 45mm height, designed to fit bottle necks and stoppers up to 30mm at their widest point. Perfect for distilleries, wineries, craft breweries, olive oil producers, hot sauce manufacturers, maple syrup bottlers, and any producer seeking a simple, effective tamper-evident seal across small-batch and high-volume bottling operations alike.

Why Choose 31×45mm 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
Three finish options — matte gold, matte black, and clear/transparent — provide flexible branding choices to complement a wide range of label and packaging designs
Tamper-evident seal communicates product integrity to consumers and meets standard bottling presentation expectations across spirits, food, and beverage categories
Fits bottle necks and stoppers up to 30mm, with sizing guidance recommending a cap 1-2mm larger than the widest point of the stopper or neck for the best fit
High carton quantities support cost-effective procurement for production-scale bottling operations

31×45mm preformed PVC shrink caps outperform lay-flat shrink sleeves for high-volume bottling operations by arriving ready to apply straight from the carton, combining consistent heat-shrink performance with flexible color options that reinforce brand identity at every bottle.
