What packaging materials can M19 instruments test?
Flexible films, laminated barrier structures, blister, and lidding films, pouch, and sachet materials, biodegradable films and coated/metallised films.
Packaging Barrier Testing Instruments | M19 Lab
WVTR and gas-permeability instruments for packaging films and laminates — gravimetric moisture-barrier testing to ASTM E96 and non-destructive gas permeability for shelf-life R&D.
At M19 Labs, we help packaging manufacturers ensure high-quality products with advanced instruments for barrier (WVTR) and gas-permeability characterization of films and laminates.
Packaging manufacturers engineer barrier performance for shelf-life and sustainability. M19 deploys custom-configured instruments so films and laminates are validated to ASTM barrier standards with traceable data.

Frequently asked questions
Which barrier standards are supported?
ASTM E96 for water-vapor transmission (WVTR), ASTM D737-18 for gas permeability, and ASTM D1434 for diffusional / gas transmission — listed per product.
How is WVTR measured?
The gravimetric upright-cup method records vapor-mass gain across the specimen over time under controlled humidity, computing WVTR, permeance, and permeability.
Can data support shelf-life studies?
Yes. Barrier data feeds directly into shelf-life prediction, film development and lot acceptance, with secure records and PDF/CSV export.
Is local support available?
Yes. Domestic manufacturing gives faster service, ready spares, lower cost and a 2-year extended warranty.
