Securing tamper-evident seals begins with testing the film at its manufacturing stage. Manufacturers subject the heat-shrink film to a battery of tests to ensure it meets stringent quality and performance standards.
Shrinkage Testing includes the shrinkage ratio, shrinkage temperature, and shrinkage force. Consistent and predictable shrinkage creates a tight and secure seal. Too little shrinkage may result in a loose seal, while excessive shrinkage could distort the container. Industry standards such as ISO-14616 provide guide to these tests.
Once the film reaches the pharmaceutical packaging facility, further tests like seal integrity and opening force are conducted to verify the integrity and effectiveness of the tamper-evident seal.
Labthink C631H Thermal Shrinkage Tester is designed and developed in accordance with ISO 14616 and GB/T 34848, for determination of shrinking force, contracting force and shrinkage ratio of heat shrinkable films. Shrinking force greater than 0.01N can be detected.
The use of heat-shrink films in pharmaceutical tamper-evident packaging underscores the industry's commitment to product safety and security. Rigorous testing at every stage, from film manufacturing to final packaging, is vital to ensure that these seals function as intended. By adhering to stringent testing protocols and industry standards, film manufacturers and pharmaceutical companies can confidently provide consumers with safe and secure medications.
As the demand for functional packaging materials grows, testing methods are evolving to ensure a more comprehensive evaluation of packaging films. Labthink encourages collaboration with packaging industry companies for quality control! Visit the website www.labthink.com to learn more!
