1. Blank Bottle

The journey begins with the production of blank bottles.

2. Labeled & Filled

Once produced, these bottles are labeled and filled.


3. Collected & Sorted

After use the bottles are collected and sorted for recycling.


4. Bottles Ground into Flakes

The collected bottles are then ground into flakes to prepare them for the recycling process.

5. Sink and Separate

PET flakes and labels undergo a separation process where the ink is suspended in a bath while the materials sinks.



6. Ink is Removed

The clean PET flakes and labels are pelletized for reuse.



7. New Bottle made with rPET

The second generation bottle is created from the pellets.

Understanding Shrink Sleeves

Made from various plastic substrates such as PVC, PETG, or OPS. They are designed to fit snugly around containers, providing 360-degree coverage. The application of heat causes the sleeve to shrink tightly, conforming to the shape of the product, whether it's a bottle, jar, or container. High-barrier film laminations provide superior protection against moisture, oxygen, and other environmental factors. This ensures extended shelf life and product freshness, particularly for perishable goods.

Versatility and Customization

They can accommodate a wide range of container shapes and sizes, making them ideal for products with irregular or non-standard packaging. Additionally, shrink sleeves offer extensive customization options, allowing brands to showcase vibrant graphics, detailed product information, and eye-catching designs, ultimately enhancing shelf appeal and brand recognition.
