Matching Barrier Performance to Product Sensitivity
Barrier performance plays a critical role in nutraceutical packaging, particularly for products that are sensitive to moisture, oxygen, or environmental exposure. Tablets, capsules, and specialty formulations can be impacted by humidity and oxidation, leading to reduced shelf life, loss of potency, or changes in appearance. While mono-material films may be sufficient for less sensitive applications, many nutraceutical products require enhanced barrier structures to ensure product stability throughout distribution and storage. By offering a range of barrier options—from moderate protection to high-performance structures—kpEnhance® enables manufacturers to match the right level of protection to the specific needs of each product without overengineering the package.
Selecting the optimal film depends on a range of factors, including product sensitivity, desired shelf life, and processing conditions. Our material science experts can help evaluate these variables and guide you to the right structure—ensuring the best balance of protection, efficiency, and performance for your specific application.
MVTR Performance by Structure
MVTR (38°C / 90% RH). Lower values indicate higher moisture barrier.
Test conditions: MVTR (g/m²/day) @ 38°C / 90% RH.
