Shrink Sleeving FAQ

Shrink sleeving a container can be a daunting task to the uninitiated. There are many variables to consider such as material, sizing, varnishes, etc. which is why working with a third-party decorator like Eastgate Group can be a great idea. In the post below we consider the frequently asked questions when shrink sleeving a container.

What are shrink sleeve labels?

Shrink sleeve labels are heat-sensitive plastic film labels that conform tightly to the shape of a container when heat is applied, offering 360-degree coverage and vibrant graphics for bottles, cans, and more.

What types of materials are used for shrink sleeves?

The main materials are PET, PETG, CPET, and OPS. Each has unique benefits for durability, clarity, recyclability, and shrink performance. Eastgate Group will help select the best option for your needs.

How do you apply shrink sleeve labels?

Shrink sleeves are vertically slipped over the container and then exposed to heat via steam, hot air, or radiant tunnels, causing the label to conform tightly to the container’s shape. Accurate application requires uniform heat. Shrink sleeves can be applied by hand or machine.

What are the minimum order quantities?

Digital print minimums can start at a few hundred sleeves per version, while flexographic printed sleeves often require 20,000 or more. Eastgate Group offers flexible solutions for both small and large projects.

Are shrink sleeve labels recyclable or sustainable?

This is one of the most frequently asked questions when shrink sleeving a container which means film manufacturers are working hard to provide solutions like the Klockner’s SmartCycle film for PET bottles. Options like PETG and CPET offer improved recyclability. Ultimately, it depends on your container and goals. Eastgate Group provides guidance on eco-friendly materials and can recommend the best fit for your brand’s sustainability goals.

Can shrink sleeves be used on any container shape?

Shrink sleeves work on most shapes, including round, square, and irregular containers, but best results require proper measuring and material selection. Typically, the shrink percentage from the largest diameter to the smallest diameter of your container needs to be within 60-70%. Eastgate Group provides container compatibility checks and trial runs.

How long does it take to receive shrink sleeved containers?

Lead times vary based on artwork approval and order complexity, typically ranging from 3-6 weeks after proof approval. Eastgate Group provides reliable estimates options when available.

What information is needed for a shrink sleeve quote?

Key details include container drawing, packaging specs, order volume, artwork specs, and material preference. Eastgate Group’s team helps you gather this info efficiently.

Can shrink sleeve labels include barcodes or tamper-evidence?

Yes, shrink sleeves can be printed with scannable barcodes and designed for tamper-evident sealing or neck-band applications for added consumer safety and trust.

What is a shrink sleeve lay flat?

The shrink sleeve lay flat is the width of the sleeve after the two ends are seamed together. It’s a critical measurement that needs be to calculated before production. Too small and the shrink sleeve won’t fit on your container. Too large and the shrink sleeve becomes distorted from excessive shrinking.

What is a shrink sleeve cut length?

Cut length refers to the length of the sleeve from top to bottom and is a critical measurement that needs to be calculated and tested before production. Shrink sleeves don’t shrink much in the vertical direction so in theory, the cut length should equal the coverage you want on your container. However, every container and film material is different which is why working with a third-party decorator like Eastgate Group is helpful.

Do you use steam or dry heat in your tunnels?

At Eastgate Group, we steam shrink tunnels because they provide a more uniform shrink process. Dry, conventional or radiant heat can be spotty and hard which results in artwork distortion and melted bottles.

What’s the shelf life of a shrink sleeve?

Film manufacturers recommend applying shrink sleeves within 6-9 months to avoid potential issues. We’ve seen shrink sleeves that are 2+ years old work fine but it’s not recommended. Eastgate Group offers temperature controlled storage for ongoing business.

What is a seam?

After printing your artwork on flat film, the two ends of the label are folded in and seamed together which create the “sleeve” or tube shape. Every shrink sleeve has a seam and Eastgate Group recommends creating your artwork with this in mind. Eastgate Group has an inhouse graphics department to ensure your artwork is press ready!

How much does shrink sleeving equipment cost?

This is a key frequently asked questions when shrink sleeving a container in house or via third party. In order to apply shrink sleeves to a container you need at a minimum a shrink tunnel and conveyor belt. To do it at reasonable speed you will also need an applicator with the right tooling. This investment can be anywhere from $200k – $1mm depending on your requirements. It’s a significant capital expenditure which is why working with a third-party decorator like Eastgate Group can save you from a costly mistake.
