Shrink sleeve packaging has become one of the most popular labelling solutions in the Indian FMCG, pharmaceutical, and beverage industries. Known for its 360-degree branding potential, vibrant graphics, and tamper-evident sealing, shrink sleeve labels are increasingly replacing traditional labels. But to achieve flawless results, understanding the shrink sleeve application process is crucial.
In this blog, we will take you through everything you need to know about shrink sleeves, from their benefits and application techniques to choosing the right equipment for your production line.
What is Shrink Sleeve Application?
The shrink sleeve application process involves placing a printed shrink sleeve over a container and then applying heat or steam to make it conform tightly to the product’s shape. This process not only creates a visually appealing package but also ensures product protection and security.
Shrink sleeves are commonly used on bottles, jars, cans, and even uniquely shaped containers. This is particularly useful in the Indian market, where product differentiation is key to attracting consumers on crowded shelves.
Benefits of Using Shrink Sleeves
Here’s why many Indian manufacturers are choosing shrink sleeves for their packaging:
- 360-Degree Branding: Full-body coverage gives brands maximum space to communicate.
- Tamper Evidence: Shrink sleeves can seal the cap, providing safety assurance.
- Compatibility with Odd Shapes: Works well with curved, contoured, and non-standard packaging shapes.
- Durability: Resistant to moisture, friction, and rough handling during logistics.
- Premium Look: High-quality graphics create a premium impression for products.

The Shrink Sleeve Application Process – Step by Step
The shrink sleeve application process typically involves the following steps:
1. Sleeve Preparation
Printed shrink sleeves arrive in rolls or pre-cut form. These are inspected to ensure they match the required design and size.
2. Sleeve Placement
Automatic or semi-automatic applicators place the sleeve over the container. Depending on production volume, you may opt for a high-speed applicator for efficiency.
3. Heat or Steam Tunnel
The container passes through a heat tunnel or steam tunnel. The sleeve shrinks uniformly to tightly wrap around the container. This is the most critical stage for a smooth and wrinkle-free finish.
4. Quality Check
Finished products undergo quality inspection to ensure correct sleeve positioning, smoothness, and colour consistency.
Choosing the Right Equipment
Investing in the right applicator and shrink tunnel is key to achieving consistent results. There are two main tunnel types:
- Steam Tunnel: Ideal for glass and PET bottles, providing uniform shrinkage and energy efficiency.
- Electric Heat Tunnel: Suitable for smaller setups, easy to operate, and requires less maintenance.
The right choice depends on your product material, production speed, and available infrastructure.
Not sure which tunnel suits your line? The experts at Inter Pack Technologies can help you choose the perfect combination of applicators and tunnels to meet your production needs.
Common Challenges in Shrink Sleeve Application
Even experienced manufacturers sometimes face issues during the shrink sleeve application process. Here are a few common challenges and solutions:
- Wrinkling or Distortion: Usually caused by incorrect tunnel temperature or misaligned sleeve placement.
- Colour Fading: Poor-quality ink or high heat can cause colour distortion.
- Tearing of Sleeves: May occur if the film material is too thin or the machinery is not calibrated properly.
Working with an experienced packaging partner can help eliminate these issues and ensure consistent results.
