What is CRTESS?
CRTESS stands for Chemical Resistant Tamper Evident Self-Sealing cap. It is an alternative with a superior sealing approach compared to methods like inner plugs, induction sealing, and PE foam wads.
The Heart of the Innovation: The In-Built Sealing Layer
The key to the CRTESS cap’s effectiveness is its integrated sealing layer:
The CRTESS cap is suitable for a wide range of applications considering it is designed for use with HDPE, PET, and aluminum containers. It also features a built-in cavity that accommodates industry-standard vent plugs, enabling self-venting closure solutions.
- 3-Dimensional Seal: This layer conforms to both the top and inner neck of the bottle, creating a 60% larger sealing area for enhanced security.
- Chemical Resistance: The material withstands a wide range of solvents, acids, and industrial chemicals.
- Soft and Flexible: The sealing layer adapts to uneven bottle surfaces, ensuring a perfect seal.
- Single-Component Design: The sealing layer is seamlessly molded into the cap, eliminating the need for separate components.
- Reseal ability: The cap provides a 100% leakproof and odor-proof seal, even after multiple uses.
