High Barrier Packaging Films That Protect

Barrier packaging uses materials and layered structures that limit the movement of elements such as oxygen, moisture, aromas, light, or gases between a product and its environment. High barrier packaging films are selected when product quality, freshness, stability, or shelf life depends on controlled transmission. Performance is commonly evaluated using measures such as oxygen transmission rate (OTR) and water vapor transmission rate (WVTR).

A high barrier film is engineered to provide low transmission of oxygen, moisture, or both, compared with standard packaging films. It often uses multiple layers, coatings, or laminations that combine protective performance with sealability, strength, and printability. The appropriate structure depends on the product, required shelf life, storage conditions, filling process, and measurable WVTR and OTR targets.

WVTR measures the amount of water vapor that passes through a packaging material over time, while OTR measures oxygen transmission. Lower values generally indicate stronger protection, but the best target is product-specific. A moisture-sensitive product may need a low WVTR, while oxidation-sensitive foods or products may require a low OTR. Both metrics should be considered with package format and sealing performance.

Yes. High barrier films can be supplied as roll stock for automated form-fill-seal applications when the structure is matched to the equipment and sealing process. Important considerations include film stiffness, coefficient of friction, sealant layer, temperature range, web width, and machine speed. Reviewing these requirements early helps ensure the film protects the product while running reliably on the fill line.

High barrier films are widely used for food and beverage products where controlling oxygen or moisture helps preserve freshness, texture, flavor, and shelf life. The suitable structure depends on the product’s fat content, water activity, storage temperature, distribution conditions, and desired package format. Formosa capabilities include food-safety certifications such as ISO 22000:2018, FSSC 22000, and HACCP compliance.

Yes. Custom high barrier packaging can combine protective flexible-film structures with pouch conversion and rotogravure printing. The project can be developed around pouch dimensions, barrier requirements, product functionality, desired finishes, and graphic needs. Rotogravure printing supports accurate, consistent color across long runs, while the underlying laminated structure is selected to address moisture and oxygen protection.

Barrier packaging can support medical, pharmaceutical, OTC, and aseptic applications when the material structure and production controls are appropriate for the product’s requirements. In addition to moisture and oxygen performance, these projects may require attention to cleanliness, traceability, seal integrity, and applicable specifications. Cleanroom-produced packaging capabilities include Class 10,000 cleanroom production for elevated handling needs.

Begin by outlining your product, package format, dimensions, filling method, expected production quantity, storage conditions, and required barrier performance. If available, include target WVTR and OTR values, shelf-life objectives, artwork, and any certification requirements.
