Shrink sleeve labels that stay straight on the curve.

Sleeve films and shrink percentages: how far the artwork can conform.

PETG is the workhorse film: high shrink capability, crisp print, good clarity. PVC still runs for cost-sensitive work, with less conforming range. In practice PETG will follow a contour needing shrink into the seventies, percentage-wise, and PVC into the fifties or low sixties. Those numbers describe typical film behavior. The honest number for your project comes from your container: compare the sleeve's printed layflat width against the smallest diameter it must finish tight on, and that ratio is the shrink you are asking for.

Coverage is a second decision. A full-body sleeve runs base to shoulder, or up over the closure when tamper evidence rides along. A partial sleeve bands one section, a waist wrap on a jar or a mid-panel on a jug, using less film and a simpler application. Both print the same way, and both scale from sampling to production without changing the file, which is what lets a brand test a flavor in the low hundreds and reorder in the tens of thousands.

Gloss is the film's own gift. Sleeves print in reverse, ink laid on the inside surface, so the outside face of the film becomes the finish: smooth, deep, and scuff-protected without a coating. Because sleeve film starts transparent, our presses lay a white underlay behind the color, full color plus white in one pass, so the palette stays opaque and true against amber glass or colored plastic. Every job is proofed and pressed to G7 targets, so the red you approved in the office is the red standing in the cooler.

Shrink bands: tamper evidence at the neck, the cap, or the whole bottle.

A shrink band is the simplest version of the format: a short sleeve over the cap and neck that must tear before the package opens. Perforations do the work. A horizontal perf lets the skirt separate cleanly from the cap; a vertical perf gives a starting point to strip the band away. Food, beverage, and supplement brands lean on them because an intact band reads as a sealed product from across the aisle, and White Graphics prints them in an FDA-registered facility.

Tamper evidence can also ride on the main label. A full-body sleeve extended over the closure, with a perforated break line at the cap, decorates and seals in one application: the shopper tears the perf, the band falls away, and the body art stays put. What counts as adequate evidence differs by category and retailer, and your regulatory advisor owns that final call. Bring us the requirement and the cap dimensions, and the structural team builds the band to meet it.

Artwork setup: design on the container's template, not a flat rectangle.

Every sleeve project starts with the physical container, in hand and measured. Our structural team takes diameters at the base, waist, shoulder, and neck, plus overall height and cap geometry, and builds a layflat template from those numbers with the seam strip, overlap, and shrink zones marked. Designing on a plain rectangle sized to the circumference is how straight logos end up bent. Designing on the template means every element already knows which zone it lives in.

Distortion compensation starts with a physical test. A printed grid sleeve goes onto the physical container and through the tunnel; where each cell lands tells us precisely how the film behaves on that shape, and that measurement drives the compensation applied to your file. Type has floors on shrinking film: hold body copy near six point or larger in calm zones, bigger and bolder where the film works hardest, and give reversed-out type extra weight so the stroke survives the compression.

Approval belongs on the bottle. A flat proof can confirm color and copy; it cannot tell you whether the shoulder pinches your wordmark or the seam grazes the barcode. Before a production run, order a prototype run on your actual container: a finished, shrunk sample you can stand on a shelf, turn in your hand, and judge exactly the way a shopper will, from the side, at arm's length, in a two-second glance.
