A Package Leak Tester is a precision instrument used to verify the seal integrity and leakage resistance of packaging materials. It detects weak or failed seals before products reach the market — preventing contamination, spoilage, product recalls, and regulatory non-compliance. It is essential for industries such as food, pharmaceuticals, medical devices, daily chemicals, and automotive components. What are the two Package Leak Testers available from Flexitest and how do they differ? Flexitest offers the **C660M Leak and Seal Strength Tester** and the **C660B Vacuum Leak Tester**, both manufactured by Labthink. The C660M uses the **positive pressure method** to quantitatively measure burst pressure, seal strength, and creep resistance. The C660B uses the **negative pressure (vacuum/bubble emission) method** to visually detect leaks by submerging the package in water under vacuum — ideal for qualitative leak detection across a wide range of packaging types. What test modes does the C660M Leak and Seal Strength Tester support? The C660M supports four test modes — **burst test, creep test, creep-to-failure test**, and **pressure retaining test** — with a standard test range of **0 to 600 KPa** (extendable to 1.6 MPa optionally) and pressure accuracy of ±0.25% FS. It also supports both **restrained and unrestrained distension** methods, making it versatile for flexible pouches, aseptic packages, blister packs, tamper-evident closures, aerosol valves, and flexible tubes. How does the C660B Vacuum Leak Tester work and what standard does it follow? The C660B submerges the specimen in water inside a sealed vacuum chamber and evacuates the chamber to create a pressure differential. Any leak is identified by observing a steady stream of air bubbles escaping from the package, or by watching for expansion and recovery after vacuum release. It conforms to **ASTM D3078** and **GB/T 15171**, and achieves a vacuum level of **0 to −90 KPa** with automatic constant pressure compensation for consistent, repeatable results. What types of packaging and materials can be tested using these instruments? The **C660M** is applicable to flexible pouches, aluminium-plastic and paper-plastic laminates, aseptic packages, flexible tubes (cosmetics, food, pharmaceuticals), tamper-evident closures, aerosol valves, blister packs, and pressurised caps for beverages, edible oil, and food cans. The **C660B** tests glass, plastic, and metal bottles, pipes, cans, composite bags and boxes, pen refills, electronic components, and medical instruments — including packages subjected to drop or compression tests. What international standards do the C660M and C660B comply with? The **C660M** complies with **ISO 11607-1, ISO 11607-2, ASTM F1140, ASTM F2054**, and pharmaceutical packaging standards including **YBB 00252005** and **YBB 00162002**. The **C660B** complies with **ASTM D3078** and **GB/T 15171**. Both instruments are optionally configurable to meet **GMP requirements**, making them suitable for validated pharmaceutical and medical device manufacturing environments. What data management and reporting features do the C660M and C660B offer? Both instruments are equipped with an **industrial-grade intelligent touch screen** featuring a simplified interface, one-button operation, and remote upgrade capability. They store **up to 1,200 test records** with automatic data storage and power-failure memory. Optional features include a micro-printer, USB data transfer ports, multi- level user management with password login, PDF report export, and Labthink’s **DataShield ™ System** for LIMS integration and secure data traceability. What is the difference between the restrained and unrestrained distension methods on the C660M? In restrained distension, the package is physically confined during pressurisation to simulate real-world conditions such as stacked or shelf-stored packaging. In unrestrained distension, the package is free to expand under pressure, reflecting burst resistance under open conditions. The C660M supports both methods, allowing users to select the approach that best matches their applicable test standard or end-use scenario. How long can the C660M hold pressure, and what does this enable? The C660M supports a pressure retaining time of **0.1 seconds up to 999,999.9 seconds**( approximately 11.5 days). This enables extended **creep and long-duration deformation monitoring tests** — critical for validating packaging shelf-life performance, assessing seal fatigue under sustained load, and simulating transportation and storage stress conditions.
