How to Use High Shrink Ratio PETG Film?

Understanding High Shrink Ratio PETG Film

High shrink ratio PETG (Polyethylene Terephthalate Glycol) film is a versatile packaging material widely used in the food and beverage industry, medical packaging, and retail. Its ability to shrink efficiently allows it to create a snug fit around products, enhancing protection and display. Here’s how to effectively use high shrink ratio PETG film.

1. Prepare Your Workspace

• Ensure the workspace is clean, dry, and well-ventilated.
• Gather all necessary materials: PETG film, heat source (e.g., heat gun or tunnel), products to be packaged, and any additional tools (scissors, tape, etc.).

2. Choose the Right Product Size

• Measure the dimensions of the product you intend to package.
• Select a PETG film size that allows for adequate shrinkage while leaving enough excess material to fold over and seal.

3. Cut the PETG Film

• Using scissors, cut the PETG film according to the dimensions needed, factoring in additional material for sealing.
• Make sure your cuts are straight to achieve a clean presentation.

4. Place Your Product on the Film

• Center the product on the cut piece of PETG film.
• Ensure that there's an adequate overlap of film on all sides of the product for effective sealing.

5. Fold and Seal the Edges

• Fold the edges of the film over the product tightly, ensuring no air is trapped inside.
• Use tape or a heat sealing machine to secure the edges. If using a heat sealer, follow manufacturer's instructions for the optimal temperature and time settings.

6. Apply Heat to Shrink the Film

• Using a heat gun, carefully apply heat from a distance of about 6 inches, moving it around the film to ensure even distribution.
• If using a heat tunnel, place the sealed package inside and allow it to pass through, following the manufacturer's recommended settings for time and temperature.

7. Allow to Cool

• Once the film has fully shrunk around the product, set it aside to cool for a few minutes.
• This will help the film maintain its fitted shape and secure the contents properly.

8. Inspect the Finished Product

• Check that the film has evenly wrapped around the product without any gaps or wrinkles.
• Ensure that it is securely sealed to prevent any leakage or spoilage.

9. Store Properly

• If not using immediately, store products in a cool, dry place to maintain the integrity of the film and the product.
• Avoid exposure to direct sunlight or extreme temperatures that may compromise the quality of the PETG film.

Conclusion

High shrink ratio PETG film can significantly enhance packaging efficacy when used correctly. By following these structured steps, you can ensure that your products are well-protected and impeccably presented.
