Product Overview

The HM-MF03A Leakage and Seal Strength Tester is an advanced positive-pressure testing instrument designed for the quantitative measurement of seal strength, burst pressure, and seal integrity in flexible packaging. Tailored specifically for packaging pouches, sachets, and sterile medical barriers, the instrument operates by applying internal positive air pressure to simulate real-world mechanical stress, handling impact, and altitude changes. It delivers precise determinations of edge heat seal strength, overall burst limits, and package creep behavior to help manufacturers optimize packaging line parameters, evaluate film barrier formulations, and prevent seal failure during transportation and shelf storage.

Key Features

7-Inch Color Touchscreen Interface: Features an intuitive, one-touch operational menu with interactive test execution, real-time status monitoring, and support for remote firmware maintenance and upgrades.
Imported SMC Pneumatic Components: Built with premium pneumatic components from internationally recognized SMC brand, ensuring precise airflow control, robust pressure holding, and repeatable operation.
High-Precision Internal Pressure Sensor: Integrated pressure sensor accurately tracks internal sample pressure variations with ±1% FS accuracy and high sensitivity.
Real-Time Dynamic Curve Display: Displays real-time pressure-time response curves throughout the pressurization cycle, enabling instant visual detection of seal yield points, micro-leaks, and catastrophic rupture.
Three Standard Test Modes: Provides automated execution for burst (cracking) test, creep test, and creep-to-failure (creep to crack) test modes to meet comprehensive packaging evaluation requirements.
Traceable Data Management: Incorporates multi-level password login and user access permission controls that comply with China GMP guidelines for pharmaceutical packaging data traceability.
Comprehensive Data Output: Equipped with a built-in micro thermal printer and universal USB data interface for rapid test report generation, external data export, and archiving.
Bilingual Operation: Instant one-button toggle between English and Chinese user interfaces for versatile laboratory environments.

Applications

Plastic Composite Bags: Quantitative burst and seal strength evaluation for multi-layer plastic films, vacuum pouches, boil-in-bag laminates, and retort pouches.
Aluminum Foil and Barrier Pouches: Pressure containment and seal failure resistance analysis for aluminum-plastic composite bags and high-barrier foil food packaging.
Paper-Plastic Composite Bags: Heat seal integrity, delamination limits, and burst threshold testing for medical device sterilization pouches and sterile paper-plastic wraps.
Blister Packaging: Rupture pressure and cavity seal strength verification for pharmaceutical blister packs, medical trays, and thermoformed unit-dose packages.
Creep and Creep-to-Failure Analysis: Sustained internal pressure retention testing of packaging bags and containers under specified holding pressure to simulate long-term transport stress.
