High Barrier Film Laminations
High barrier packaging plays a vital role in protecting product integrity by preventing the permeation of oxygen, carbon dioxide, moisture, light, and other elements that compromise quality. Since 1965, Glenroy has been a trusted partner for brands that need barrier film laminations engineered for even the most challenging products.
Why Choose Glenroy for Barrier Packaging
Not all flexible packaging products deliver the same level of protection. Glenroy specializes in custom-engineered barrier packaging solutions designed to extend shelf life, preserve product quality, and meet the specific demands of your formulation. Whether your product requires protection from oxygen, water vapor, UV light, microbial barrier threats, or chemical migration, our packaging engineers will identify the right packaging material and structure for your application.
As a U.S.-based manufacturer with decades of barrier film expertise, we deliver shorter lead times, full quality control, and responsive technical support. From food packaging and nutraceuticals to industrial materials and personal care, Glenroy’s high barrier flexible packaging keeps your products performing and your brand protected.
Custom-Engineered Foil & Non-Foil Barrier Films
Glenroy engineers both foil and non-foil barrier packaging laminations to meet stringent barrier property requirements, drawing on deep material science expertise and a wide range of raw materials and related materials.
Foil Laminations: Aluminum foil provides near-total protection against oxygen, carbon dioxide, moisture, and visible light, making it ideal for products that demand the highest barrier performance, including sterile barrier system applications.
Non-Foil Laminations: For applications requiring product visibility or cost efficiency, we engineer structures using metallized film, coextruded plastic film, and barrier coatings such as ethylene vinyl alcohol (EVOH) and aluminum oxide (AlOx). These flexible packaging materials deliver excellent barrier properties with strong mechanical properties without sacrificing shelf appeal.
Barrier Packaging Applications
Glenroy’s packaging solutions serve a wide range of industries, including:
- Pharmaceutical and medical device – surgical instruments, medical testing devices, prescription and over-the-counter medications, including capsules, powders, ointments, gels, and dissolvable strips
- Food packaging — sauces, snacks, fresh produce, powdered mixes, and shelf-stable meals, where reducing food waste is a priority
- Nutraceuticals — vitamins, supplements, and medicinal powders requiring a strong moisture barrier
- Personal care — toothpastes, lotions, and products requiring aroma and flavor retention
- Household chemicals — cleaners, detergents, and chemically aggressive formulations
- Oils & Lubricants — motor oils, industrial lubricants, solvents, and other chemically aggressive formulations
Product & Package Compatibility Testing
In our on-site package engineering lab, we analyze your product’s unique formulation, test multiple flexible packaging material options for compatibility, and recommend the innovative solution that delivers optimal barrier performance throughout your product’s life cycle. This process helps reduce food waste, protect product quality, and ensure your packaging meets sustainability goals while minimizing environmental impact.
Frequently Asked Questions
What is barrier packaging?
Barrier packaging refers to flexible packaging materials engineered to prevent the transmission of oxygen, carbon dioxide, moisture, visible light, and UV light. The right barrier film structure extends shelf life and protects product integrity from production through consumer use, playing a vital role in reducing food waste for products like fresh produce, supplements, and prepared foods.
What materials are used in high-barrier packaging?
Common barrier materials include aluminum foil, ethylene vinyl alcohol (EVOH), aluminum oxide (ALOx), polyethylene terephthalate (PET), metallized films, and coextruded plastic film. Depending on the application, a single-layer or multi-layer lamination may be recommended. Glenroy engineers custom laminations using these and other raw materials to meet your specific requirements.
How do I know which barrier structure is right for my product?
Our packaging engineers evaluate your formulation, shelf life requirements, and distribution conditions to recommend the optimal structure. We conduct compatibility testing to confirm barrier performance, including oxygen transmission rate and moisture barrier testing, before production begins.
Can Glenroy produce sustainable packaging with high barrier properties?
Yes. We offer recyclable, mono-material packaging structures and post-consumer recycled (PCR) content packaging options that help brands reduce environmental impact while maintaining barrier performance. Our team works with you to balance sustainability goals with the barrier property demands of your specific application.
