Foil Barrier Bags

When products need protection from moisture, oxygen, light, and other environmental factors, the right packaging material can make a significant difference. At Royco Packaging, we supply foil barrier bags designed for demanding applications where product preservation and dependable barrier performance matter. Our experience with military, industrial, aerospace, and specialty packaging allows us to approach each requirement with the technical knowledge needed to identify an appropriate solution.

From components requiring long-term preservation to products moving through demanding supply chains, we understand that packaging must do more than simply contain an item. It needs to protect the contents throughout storage, handling, and transportation.

Our team can help customers evaluate their requirements and select packaging materials suited to the application.

About Our Foil Barrier Bags

Foil barrier bags are flexible packaging products constructed to create a protective barrier between packaged contents and the surrounding environment. Their barrier properties make them particularly useful when exposure to moisture, air, light, or other external conditions could affect the condition of the product.

We offer barrier packaging for applications where maintaining the integrity of the contents is a primary consideration. Depending on the application, foil-based barrier materials can be incorporated into packaging systems designed for preservation, storage, transportation, and protection of sensitive products.

For military packaging, foil barrier bags are made from barrier material qualified to MIL-PRF-131 (watervaporproof, greaseproof, flexible, heat-sealable). MIL-PRF-131L covers two classes: Class 1 with a plastic, non-woven backing for general use, and Class 3 with a woven scrim backing where higher strength is needed. Both are limited to a water vapor transmission rate of 0.02 g/100 sq. in./24 hrs after flexing.

Bags made from that material are specified under MIL-DTL-117J as Class E (watervaporproof, greaseproof): Type I, Class E, Style 1 for heavy-duty opaque bags, and Type IV, Class E, Style 1, made from MIL-PRF-131 Class 3, for extra-heavy-duty applications. Our SpecPack™ 1E1 bags are MIL-DTL-117 Type I, Class E, Style 1, and we build to the current J revision.

It is worth being precise about the barrier. A foil laminate is watervaporproof: it keeps out humidity, not just liquid water. Polyethylene and MIL-PRF-121 bags are waterproof only. If moisture vapor can damage the item, specify a watervaporproof bag.

Our experience with military packaging is especially relevant when packaging must align with established specifications. We work with customers who require packaging materials for demanding applications, including defense and industrial programs. Our military packaging solutions include barrier materials and flexible packaging designed around military requirements, including MIL-DTL-117 custom pouch converting.

Foil barrier bags can also play a valuable role in aerospace applications. Aerospace components may travel through different environments before reaching their final destination, making protection during transportation and storage an important consideration. Our aerospace packaging solutions are developed with the protection and preservation requirements of aerospace components in mind.

We understand that there is no single packaging configuration suitable for every product. Dimensions, material construction, sealing requirements, storage conditions, handling requirements, and applicable specifications can all influence the appropriate packaging choice.

Benefits of Our Foil Barrier Bags

Strong Environmental Protection

One of the primary advantages of foil barrier packaging is its ability to create a protective barrier between the contents and environmental exposure. This can be particularly valuable for products that need protection from moisture, air, and light during storage or transportation.

Protection for Sensitive Products

Certain components and materials can be affected by environmental conditions long before they are needed for use. A suitable barrier bag can create an additional layer of protection, helping maintain packaged products throughout their intended storage and handling cycle.

Useful for Long-Term Storage

Foil barrier bags can be incorporated into preservation strategies for products that may remain in storage for extended periods. When combined with other appropriate packaging materials, they can form part of a broader approach to maintaining product condition over time.

Adaptable Packaging Options

Packaging requirements vary considerably from one application to another. We can work with customers to determine the appropriate bag configuration, dimensions, material requirements, and sealing approach based on the intended use. For applications involving specific military requirements, our knowledge of MIL-SPEC packaging helps us address technical considerations with greater precision.

Suitable Across Multiple Industries

Barrier packaging has applications across military, aerospace, industrial, and other specialized environments. Our industrial packaging solutions are designed around the practical requirements of industrial operations, while our experience in other specialized markets gives us a broader understanding of product protection.
