- A beverage company reduced spoilage rates by 50% by using plastic liners to provide tamper evidence and prevent oxygen ingress.
- A pharmaceutical company improved the stability of its products by utilizing paper liners to absorb moisture and prevent contamination.
Tips and Tricks for Effective Cap Liner Selection:
- Consider the product type: Determine the compatibility of liners with the product's composition, acidity, and moisture content.
- Choose the right material: Select a liner material that offers the necessary barrier properties and durability for the product's storage conditions.
- Ensure a proper fit: Use liners that are specifically designed for the size and shape of the cap or container to prevent leakage or contamination.
- Use a laminating process: Laminate multiple layers of liners to enhance barrier properties and provide additional protection.
Common Mistakes to Avoid:
- Selecting the wrong material: Using a liner material that is not compatible with the product can compromise its integrity and shelf life.
- Improper installation: Failing to ensure a proper fit can result in leaks or contamination.
- Overtightening the cap: Excessive tightening can damage the liner and reduce its sealing effectiveness.
