ACA Permi Lab
LP 100 / LP 300
Air permeability analyzer for low porous materials
ACA Permi Lab is a fast and accurate air permeance analyzer designed for laboratory testing of fiber-based packaging materials. It helps manufacturers, converters, and R&D teams evaluate how well a material protects against air, moisture, and gases – key factors for shelf life, product safety, and material performance.
It is especially suitable for low-porosity materials, where traditional testers often lack sensitivity or measurement range.
Measures up to 10× lower porosity than standard testers
Ideal for fiber-based packaging materials with barrier requirements
Fast, repeatable measurements – excellent for quality control and R&D
Compact, lab-ready design
High correlation with barrier property tests
Key benefits of ACA Permi Lab
Wide measurement range
Choose between two models depending on your application:
LP 100: Gurley 5 – 2,500 s
LP 300: 100- 40 000 pm/ Pa*s
Additional units such as Bendtsen, Coresta, and others are available on request – ensuring compatibility with your existing standards.
Fast, repeatable testing of fiber-based materials
Permi Lab delivers accurate results in less than 10 seconds, even with low-permeability substrates. This enables rapid quality checks and reliable R&D support.
Ideal for CD profile evaluation
The system makes it easy to measure cross-direction (CD) profiles, providing valuable insight into material uniformity and process consistency.
Supports shelf life, barrier, and product protection goals
Air permeance affects how packaging interacts with moisture, gases, and oxygen. Permi Lab helps you evaluate these factors to optimize shelf life and product performance.
Accelerates material development and strength optimization
By identifying and minimizing permeance fluctuation, Permi Lab contributes to more stable mechanical properties and stronger packaging structures.
Cost-efficient alternative to time-consuming barrier testing
Permi Lab shows a high correlation to traditional barrier property tests, making it a smart and affordable option for preliminary screening in packaging R&D.
