Shrink sleeves are plastic labels that are shrunk onto a container using heat. While they offer superior shelf appeal, they present unique challenges:
The term "repack" or multipack refers to the process of bundling multiple products together (e.g., a 6-pack of soda cans or a 3-pack of body wash). From a technical design perspective, multipacks are significantly more difficult to master than single containers due to shifting tension, valleys between containers, and often irregular grouping geometries.
Ensures branding remains perfectly aligned and legible, regardless of the container shape.
Different materials (PETG, PVC, OPS) feature unique shrink ratios and mechanical behaviors.
Total Quality Labels experienced a dramatic improvement using the Toolkit. Before Esko, complex shrink sleeve jobs took 20 to 24 hours. After implementing the solution, "shrink sleeve jobs now take us two to three hours". This roughly 90% reduction in turnaround time directly correlates to the elimination of the trial-and-error press runs required to test distortion manually.

Designers can see their 2D artwork mapped onto the 3D container in real-time inside Adobe Illustrator.
: Automated pre-distortion removes the trial-and-error phase from prepress, allowing files to move to plate-making and printing much faster.
Trial and error, multiple physical prototypes, high costs, and slow time-to-market.
The repack workflow begins by defining the physical structure within the standalone application. Designing shrink sleeve packaging with Studio Before Esko, complex shrink sleeve jobs took 20 to 24 hours
When a shrink sleeve is applied to a contoured container, the heat causes the plastic to shrink unevenly. Graphics in high-shrink areas compress, warp, and stretch. Traditionally, packaging professionals relied on expensive, time-consuming physical prototyping loops to test and correct these distortions.
The software functions by simulating the physical shrinking process. It takes a 3D model of a container (such as a bottle, jar, or can) and computes how a flat material sleeve will wrap around and shrink onto that shape. Key Capabilities:
The Studio Visualizer adds the "repack" logic by converting raw 3D data into photorealistic images. It simulates finishing effects like gloss or matte lamination, lighting conditions, and material textures. It can create interactive 3D PDFs that rotate 360-degrees, high-resolution JPGs for presentations, or even 360-degree pack shot animations that can be shared with clients across the globe. For a "repack" professional—someone taking an existing design and applying it to a new, different shaped container—this visualization capability is essential for validating the design instantly.
Optimizing Repackaging with Esko Studio and Visualizer Studio Toolkit for Shrink Sleeves leaving air gaps
Shrink sleeves are one of the fastest-growing segments in packaging. They offer 360-degree branding, vibrant graphics, and unique shelf appeal. However, designing them presents a major technical challenge: graphic distortion.
Designing shrink sleeves for multi-pack repacks introduces severe geometric complexity. Instead of shrinking a sleeve around a smooth, symmetrical bottle, the sleeve must constrict around multiple objects simultaneously, leaving air gaps, sharp angles, and deep recesses between the containers. Managing Multi-Object Complexities
The core ROI of Esko Studio lies in its tool. Without digital tools, a designer must guess how much to stretch a logo horizontally so that it looks normal after shrinking.
