Métodos clave de prueba de envases sanitarios para garantizar la fiabilidad de la barrera estéril

In the healthcare industry, packaging engineers rely on standard material properties like tensile strength or moisture transmission rates to evaluate materials. However, real-world challenges demand advanced Healthcare Packaging Testing to predict how materials perform under operational stress, sterilization, and distribution. Below, we explore specialized tests that address critical risks and ensure sterile barrier system integrity.

1. Evaluating Film Durability with the Gelbo Flex Test

Films used in medical packaging must endure repetitive stress during transportation. The Gelbo Flex Test simulates repeated flexing to identify a material’s resistance to pinhole formation. Surprisingly, thicker films don’t always outperform thinner ones in flex crack resistance. This test ranks films based on their ability to withstand dynamic stressors, helping engineers select optimal materials for devices prone to movement-induced damage.

2. Mitigating Seal Creep Risk in Sterilization Environments

Seal failures during ethylene oxide (EO) sterilization can compromise sterility. Elevated temperature and humidity conditions weaken adhesive coatings, leading to Seal Creep Risk. Testing under accelerated heat and humidity conditions reveals how coatings maintain seal strength over time. For thermo-form-fill-seal (TFFS) systems, pairing this with Hot Tack Testing ensures seals withstand machine dynamics and device weight before cooling.

3. Ensuring Material Resilience in Cold Temperature Performance

While heat and humidity dominate testing focus, Cold Temperature Performance is equally vital. Materials like rigid trays become brittle in freezing conditions, risking cracks during shocks. Testing methods include flexing or exposing sealed films to sub-zero temperatures to evaluate brittleness. Flexible packaging systems often outperform rigid designs here, but validating performance ensures compliance with cold-chain logistics.

4. Puncture and Abrasion Resistance for Device Safety

Sharp medical devices demand films with high Puncture Resistance, measured by force required to penetrate from both inside and outside. Similarly, Abrasion Testing quantifies how often a weighted stylus wears through films—critical for designs with folds rubbing against cartons or devices abrading pouch interiors.

Optimizing Testing Strategies for Real-World Scenarios

Beyond generic data sheets, Healthcare Packaging Testing must align with the sterile barrier lifecycle. Collaborate with suppliers to prioritize tests like the Gelbo Flex Test or Cold Temperature Performance evaluations. By addressing risks like Seal Creep Risk early, teams streamline development and avoid costly post-production failures.

Tailored testing bridges the gap between theoretical data and real-world performance. Prioritize application-specific methods to safeguard your medical devices through sterilization, transit, and storage.
