Permeability

Effective sealing is the primary assurance that a package will maintain its barrier properties against contaminants, moisture, and gases throughout its lifespan. These tests ensure the seal is strong enough to survive handling but also weak enough to be easily opened by the end user, which is critical for product safety and consumer satisfaction.

Seal Strength: Measures the force required to open the seal (peel or burst), ensuring it meets specifications for both tamper-resistance and accessibility.
Heat Sealing Parameters: Determines the optimal temperature, dwell time, and pressure needed for the packaging material to form a perfect, consistent seal.
Leak Detection: Procedures verify the seal is completely airtight, often using vacuum or pressure methods to detect pinholes, channels, or micro-leaks.
