Frequently Asked Questions

What types of barrier bags does Royco Packaging offer?

Royco Packaging offers stock and custom heat-sealable barrier bags for military, aerospace, healthcare, electronics, and industrial applications. The portfolio includes MIL-SPEC barrier pouches, static/ESD shielding bags, VCI corrosion-protection bags, moisture-barrier foil constructions, and industrial poly bags. Different materials are designed to control risks such as water vapor, grease, contamination, UV exposure, corrosion, and electrostatic discharge. Standard SpecPack™ pouches are available for rapid procurement, while Royco’s in-house converting operation can manufacture custom sizes and configurations. The company can also supply complementary desiccants, VCI wraps, humidity indicators, tapes, and certified shipping containers when the bag is part of a broader preservation system.

What is the difference between MIL-SPEC, ESD, VCI, and industrial poly barrier bags?

MIL-SPEC, ESD, VCI, and industrial poly bags solve different packaging problems. MIL-SPEC bags are manufactured to a stated military requirement such as MIL-DTL-117 using qualified barrier materials. ESD bags protect static-sensitive electronics from electrostatic discharge, with MIL-PRF-81705 available for programs that require certified military performance. VCI bags release corrosion-inhibiting chemistry to protect metal surfaces during storage or shipment. Industrial poly bags provide economical physical, dust, or general moisture protection when a high-performance military barrier is not required. Royco Packaging supplies all of these categories and can help customers choose the construction based on the item’s vulnerability, storage environment, contract, and documentation requirements.

Are custom barrier bag sizes available?

Yes. Royco Packaging can manufacture custom barrier bags to fit components, assemblies, equipment, and process requirements that do not match stock pouch dimensions. The company converts barrier roll stock in-house and supports custom widths, lengths, pouch formats, material constructions, and military MIL-DTL-117 configurations. For defense programs, custom printing such as NSN, nomenclature, or handling instructions can also be discussed. This capability is useful for oversized equipment, unusually shaped parts, circuit boards, medical devices, and aerospace components. Customers should provide the item dimensions, required material or specification, quantity, seal configuration, and any special protection or marking requirements so Royco can design and quote the appropriate bag.

Do Royco Packaging barrier bags ship with a Certificate of Conformance?

Applicable Royco barrier bags are supplied with certification documentation appropriate to the product. SpecPack™ certified military pouches ship with a Manufacturer’s Certificate of Conformance, and custom MIL-SPEC bags can be supported with material traceability and compliance documentation required by the specification or contract. The exact certificate depends on the construction being ordered; an industrial poly bag, for example, does not carry the same documentation as a MIL-DTL-117 pouch made from qualified barrier material. Royco’s ISO 9001:2015 quality system supports controlled manufacturing and inspection. Customers with government or defense receiving requirements should specify the exact certificate, revision, or traceability documentation they need when placing the order.

What industries use heat seal barrier bags?

Heat-seal barrier bags are used across military and defense logistics, aerospace manufacturing and MRO, electronics and avionics, healthcare and medical-device supply chains, and industrial manufacturing. They are valuable whenever products must be protected from moisture, grease, contamination, UV exposure, corrosion, or electrostatic discharge during storage or shipment. Royco Packaging offers several constructions so customers can select a bag based on the actual risk rather than using one material for every application. Examples include ESD pouches for circuit boards, foil moisture barriers for long-term preservation, VCI bags for metal components, and industrial poly bags for general protection. Custom sizes are available for specialized components and equipment.
