Shrink wrap labels provide 360-degree coverage of the bottle, allowing for branding, product information, and design to be displayed all around the container.

Shrink wrap labels for bottles is a printed piece of plastic, which doesn’t rely on a liner or adhesive for support. Instead, it is wrapped around a container, seamed, and exposed to heat to shrink and conform precisely to the container’s shape. Many shrink labels are created from plastic sheets that are shaped into tubes or sleeves using a seaming machine. Subsequently, the sleeve is slid onto the container and then subjected to heat in a tunnel, causing it to shrink. Another variation of the shrink label is known as roll-on shrink-on. In this method, the label is cut directly from a printed roll of film, wrapped around the container, seamed at the joining point, and then heated to initiate the shrinkage process.
What is a Shrink Sleeve?
A label that is able to encompass the entirety of the bottle/package allowing 360 degree brand recognition. The label is reverse printed, making the label and ink more durable to wear and tear. This label also allows for the label to stretch up to the cap,thereby installing a built-in tamper evident solution. With a perforation in place, the label can also be easily removed making the container recyclable.
When Are Shrink Sleeves the Right Solution?
* Drives higher product recognition/appeal
* Want better chance to capture attention in 5-10 seconds
* Increase product information
* Trying to fit a label to a uniquely contoured bottle
* Seeking a Tamper Evident Solution
* Combining two packages to be sold at one time
* Trying to stand out against competitors
* Need a durable label that will stand up to certain household chemicals
* Looking to be more environmentally conscious
What is the best material for shrink sleeve?
PVC
Polyvinyl chloride (PVC), a material familiar to many, was the primary substrate developed for the shrink sleeve label market. It remains in broad use today and benefits from a robust and well-developed global supply chain, which can make it a lower-cost option. But environmental sensitivities related to phthalate and chlorine content have been widely communicated, and have created concerns about use of PVC as a label or packaging material.
PETG
The primary material used in shrink sleeve labeling today is Polyethylene Terephthalate Glycol (PETG). Key benefits of PETG use include its widespread availability, overall film clarity, stability compared to other material options and shrink capability of up to 78 percent. In combination, these features make PETG generally fit for use in most applications. The material cost typically is at a premium relative to PVC. Generally, PETG shrinks at a higher rate than other options, which requires proper control of shrink tunnel conditions to insure label appearance is not compromised.
It is also important to remember that the shrink force of a material can have an impact in the pre-labeling of empty containers,or on labeling of thinner wall containers. Since PETG can demonstrate a higher shrink force, care must be taken to ensure shrink conditions are managed properly to avoid label or even container distortion. Overall, PETG is a shrink sleeve material that’s well suited to this rapidly growing subset of labeling operations.
OPS
Oriented Polystyrene (OPS) and Polylactic Acid (PLA) are other shrink sleeve materials used in selected applications. While OPS offers higher yield and a more controlled shrink rate, it requires careful handling and different converting materials and conditions. There is a lot of interest in PLA as it is a bio-based polymer material. Limited sources of supply, cost and handling issues have limited its adoption to date.
POF
* Premium quality shrink wrap, AKA high-clarity, decorative shrink wrap.
* Made of 100% recyclable materials
* Excellent clarity and glossy shelf appearance; great for consumer products where appearance is critical (toys, games, candies,books, foods, most retail items)
* Ability to shrink quickly and completely (shrinks when heated resulting in a finished good as soon as it comes out of the shrink tunnel)
* Durable, versatile, low cost
* Excellent for bundling multiple items together, like tissue boxes for example.
* Cross-linked POF is great for high-speed applications, providing added strength without compromising clarity and prevents build-up on sealing components
* Polyolefin is more expensive, but more durable- not as effected by temperature changes
* This material is approved for food contact
* Excellent tensile-strength and propagation-to-tear
* Pre-perforated POF is available and allows for even shrink surface, no air pockets
