LT-02 Dichtheitsprüfgerät

Introduction to Package Leak Tester

Ensuring the integrity of package seals is crucial for protecting products from contamination, spoilage, and degradation. A reliable package leak tester like the LT-02 Dichtheitsprüfgerät plays a vital role in industries ranging from food packaging to pharmaceuticals, providing essential insights into packaging quality. This advanced leak testing instrument helps manufacturers detect and address packaging defects early, ensuring that products remain safe, fresh, and compliant with industry standards.

A package leak tester verifies that a package’s seal is airtight, preventing leaks that could compromise the contents. This is particularly important in sectors where seal integrity is essential for maintaining product quality and safety.

ASTM D3078: Standard for Leak Testing

Introduction to ASTM D3078

The ASTM D3078 is a widely recognized standard that outlines methods for detecting gross leaks in flexible packaging that contains headspace gas. This standard is particularly useful for testing flexible packaging materials used in food, pharmaceutical, and medical device applications, where ensuring the seal’s integrity is paramount to product safety.

Test Methodology Under ASTM D3078

According to ASTM D3078, the package leak test is performed by submerging the test sample in a water-filled chamber. The chamber is then sealed, and a vacuum is applied to create pressure differences. If the package has a leak, air will escape through the opening, causing bubbles to form in the water. This method makes it easy to visually identify leaks, even those that are too small to be detected by other means.

This standard ensures that packaging materials can be assessed for leaks effectively, offering manufacturers a reliable way to guarantee product protection and compliance with safety regulations.

How the Package Leak Tester Works

Test Setup and Procedure

To perform a leak test using the LT-02 Dichtheitsprüfgerät, the test sample is placed inside a transparent acrylic chamber filled with water. The chamber is sealed, and the control unit begins evacuating the air until the required vacuum pressure is achieved. The package is then tested for leaks, which are indicated by the appearance of bubbles as air escapes from any small openings in the seal.

Technical Features of the LT-02 Leak Tester

• High Vacuum Capabilities: The LT-02 can achieve a vacuum pressure of up to -90KPa using a Venturi tube. This makes it capable of detecting even very small leaks in a wide range of packaging materials.
• Adjustable Test Time: The test time can be customized to suit the specific requirements of the packaging being tested. This feature ensures that both small and large packages can be tested effectively.
• SMC Vacuum Pressure Switch: The LT-02 utilizes a high-quality SMC vacuum pressure switch, which ensures precise and reliable control over vacuum levels during the test.
• Customizable Test Chamber: The chamber is made of durable, transparent acrylic and can be customized in terms of size and shape to accommodate different packaging formats, including cylindrical and cuboid shapes.
• Optional Higher Vacuum Levels: The LT-02 is compatible with a vacuum pump for higher vacuum levels, in accordance with ASTM D4991, for more stringent testing requirements.

Applications of Package Leak Testing

Industry Applications

• Food Industry: The LT-02 is crucial for ensuring the integrity of packaging in the food industry, preventing contamination, spoilage, or degradation of perishable goods.
• Pharmaceuticals & Medical Devices: For products that require sterile packaging, such as medications or medical devices, the LT-02 ensures packaging seals are free from leaks, protecting against contamination.
• Packaging Manufacturers: The LT-02 is also widely used by packaging manufacturers to test and verify the performance of their products before they are released to clients.

Sustainable Packaging Testing

With the growing demand for sustainable and eco-friendly packaging solutions, the LT-02 can help test alternative materials for leak resistance, ensuring that these new packaging types meet the same standards of safety and protection as traditional packaging materials.

Benefits of Using a Package Leak Tester

• Accuracy and Reliability: The LT-02 provides precise and reliable results, ensuring that any defects in the packaging seals are detected and addressed early in the production process.
• Cost-Effectiveness: By detecting packaging defects before products reach the market, manufacturers can avoid costly product recalls, customer dissatisfaction, and damaged goods.
• Compliance with Industry Standards: The LT-02 meets ASTM D3078 and other relevant packaging testing standards, helping manufacturers stay compliant with regulatory requirements for product safety and packaging quality.
