Aluminum-Plastic Composite Film Seal Strength Testing Machine Vacuum Chamber Leak Tester For Packaging Beverage Bottle

Introduction to the Seal Strength Testing Machine

Ensuring the integrity and strength of packaging seals is crucial in industries such as food, pharmaceuticals, beverages, and medical packaging. A high-performance seal strength testing machine plays a key role in verifying seal integrity, preventing product contamination, and maintaining regulatory compliance. This machine evaluates the ability of a sealed package to withstand pressure variations, ensuring that the product remains safe during transportation, storage, and handling.

The seal strength testing machine provides accurate, repeatable, and reliable testing results, making it an essential tool for quality control and R&D in the packaging industry. This instrument is ideal for testing flexible and rigid packages, including pouches, blister packs, plastic containers, and composite films.

Why Seal Strength Testing Matters?

Packaging failures can result in product contamination, leakage, and reduced shelf life. A seal strength testing machine helps businesses:

• Assess the durability of seals under varying pressure conditions.

• Identify weak seals that could compromise product safety.

• Optimize packaging materials and sealing parameters.

• Comply with industry regulations such as ASTM F88 and ISO 11607.

Test Methods for Seal Strength Testing Machine

1. Precision Vacuum Leak Testing

The seal strength tester places the sample inside a transparent, water-filled vacuum chamber. The system then applies vacuum pressure to detect leaks through bubble formation. This test method ensures high precision in detecting micro leaks that are otherwise invisible to the naked eye.

2. Visual Confirmation of Seal Integrity

This test visually confirms leaks through the expulsion of air bubbles, pinpointing exact leakage points in packaging materials. By monitoring air escape, the system provides a clear assessment of seal quality.

3. Sample Expansion and Recovery

If no bubbles are observed, the sample’s expansion and recovery after vacuum release help determine seal integrity. This non-destructive test method allows manufacturers to assess packaging performance without damaging the sample.

Technical Features of Seal Strength Testing Machine

1. High-Precision Control System

Equipped with an advanced PLC-controlled unit, the seal strength testing machine ensures industrial-grade stability and reliability. The intuitive HMI touch screen provides an easy-to-use interface for test setup and data retrieval.

2. Venturi Tube Vacuum System

Unlike traditional vacuum pumps, this system utilizes a Venturi tube to achieve stable vacuum pressure up to -90KPa. The use of compressed air enhances efficiency and ease of operation.

3. Real-Time Data and Visual Analytics

The machine provides more than a simple pass/fail result. By recording cumulative test data and visual analytics, users can track performance trends and optimize production processes.

4. Multi-Parameter Memory for Testing Efficiency

The instrument allows users to save up to five different parameter groups, optimizing efficiency when testing various sample types. This feature enhances productivity by eliminating the need to reconfigure settings for each test.

Additional Features for Maximum Flexibility

• Transparent acrylic chamber for clear observation of tests.

• Customizable chamber sizes for testing different package dimensions.

• Optional micro printer for direct test result documentation.

• Multi-language display support for international applications.

• Compatibility with vacuum pump systems for higher vacuum levels when required.
