Testing Induction Seals on Medicine Bottles

Induction seals, also known as seal liners, bottle liner seals, or tamper-evident seals, are critical components in pharmaceutical packaging. These thin foil or plastic liners are heat-sealed to the rim of medicine bottles, creating an airtight barrier that protects the contents from contamination, tampering, and environmental factors. Their primary functions include maintaining product integrity, ensuring safety, and providing tamper evidence. Induction seals are widely used in medicine bottles, food packaging, and chemical containers.

Testing induction seals is essential to ensure they perform their intended functions effectively. Proper testing guarantees:

• Product Safety: Prevents contamination and spoilage.
• Regulatory Compliance: Meets strict pharmaceutical standards.
• Consumer Trust: Confirms tamper evidence and ease of use.
• Quality Assurance: Ensures seals remain intact during storage and transport.

Pharmaceutical manufacturers, regulatory bodies, and consumers all benefit from these tests, as they ensure the medicine remains safe and effective until it reaches the end user.

Key Tests for Induction Seals include:

Leak Testing, such as vacuum decay or dye penetration, check the seal’s ability to prevent air or liquid from entering or escaping the bottle. A failed leak test indicates a compromised seal, which could lead to contamination or product degradation.

Labthink C690H Nondestructive Package Leak Detector is based on the testing principle of the vacuum decay method, designed and manufactured according to ASTM F2338 and other standards. It is professionally suitable for batch sealing leak detection of vials, and trace leakage detection of ampoule, cartridge bottles, infusion bottles, prefilled syringes and other pharmaceutical packaging.

Peel Strength Testing, measures the force required to remove the seal. It ensures the seal is strong enough to withstand handling and transport but easy enough for consumers to open without frustration. Proper peel strength balances durability and usability.

Induction Seal Integrity Testing, verifies the bond between the foil and the bottle rim. It ensures the seal is airtight and properly applied using heat induction. A weak bond could result in leaks or tampering.

Labthink C610M Auto Tensile Tester is professionally applicable to measurement of tensile, peeling, deformation, tearing, heat sealing, adhesive, puncture force, opening force, pulling force and low speed unwrapping force as well as other properties of plastic films, composite materials, soft package materials, plastic flexible tube, adhesives, adhesive tapes, label stickers, medical plasters, release paper, protective films, combined caps, aluminum foils, diaphragms, back sheets, non-woven fabrics, rubber and paper, etc.

Induction seals play a vital role in pharmaceutical packaging by safeguarding product quality and ensuring consumer safety. Rigorous testing, including leak tests, peel strength tests, and seal integrity tests, is crucial to validate their performance. These tests not only meet regulatory requirements but also build trust with consumers, ensuring medicines remain safe and effective from production to use. By investing in thorough seal testing, manufacturers uphold the highest standards of quality and safety in the pharmaceutical industry.
