VAL55 Heat Seal Foil Bags are high-performance aluminium barrier laminate foil bags from Valdamark Direct, specifically engineered to provide superior protection for sensitive items. Their unique multi-layer construction, featuring Polyester, Aluminium, and Polythene, creates an exceptional barrier against moisture, corrosion, oxygen, and other environmental hazards, making them a "best in class" solution for critical packaging needs.

The effectiveness of VAL55 bags stems from their sophisticated five-layer laminate construction. This design strategically combines complementary materials like PET, PE, Aluminium, and HDPE, forming a robust barrier that effectively seals out moisture, oxygen, UV light, and even aggressive gases, providing a highly stable internal environment for your products.

While the multi-material laminate provides exceptional barrier properties, the composition of aluminium foil laminated with various plastics can make single-stream recycling challenging in some areas. However, aluminium itself is widely recycled, and the robust protection offered by VAL55 bags can significantly extend the shelf life of products, potentially reducing waste from spoilage.

VAL55 bags are ideal for a vast array of moisture-sensitive and corrosion-prone products. This includes everything from precision engineering parts and manufactured components to sensitive electronics, powdered granules, and even certain consumables that require long-term preservation during transport and storage.

Compared to foil-lined paper, VAL55 bags offer significantly higher tear and puncture resistance, superior barrier performance, and excellent seal strength. Their market-leading construction ensures far better long-term protection, making them more reliable for safeguarding high-value or delicate items.

Absolutely! VAL55 bags are specifically designed for demanding transport conditions, including lengthy international shipments and sea freight, where products are often exposed to high humidity, salt water, and marine air. They ensure your goods arrive at their destination in factory condition.

Yes, these bags are an excellent choice for long-term asset preservation and storage. When properly heat-sealed, their ultra-low water vapor transmission rate maintains a stable, protective environment inside, crucial for preventing degradation of sensitive items over extended periods.

Definitely. The superior moisture and oxygen barrier properties of VAL55 bags make them highly effective for protecting sensitive electronic components from humidity, which can lead to corrosion and malfunction.

Yes, Valdamark's high-performance foil packaging, including the VAL55 material, is manufactured to conform to high standards and is widely used in regulated sectors like medical, healthcare, and pharmaceutical packaging due to its protective properties and ability to maintain product integrity.

Yes, the aluminium layer within the VAL55 laminate acts as a strong barrier against aggressive gases and prevents odor transfer, which is vital for preserving the integrity and quality of certain products.

The VAL55 material boasts very high tear and puncture resistance due to its robust construction. This makes it an ideal choice for packaging items that might have sharp edges, minimizing the risk of damage to the bag and its contents.

To achieve a secure, hermetic seal with VAL55 bags, you will need a compound foil bag sealer. These heat sealers are specifically designed to work with multi-layer foil laminates.

For optimal sealing, it is recommended to set your compound foil bag sealer to approximately 180°C (356°F) and apply heat for about 2 seconds. Always consult your sealer's instructions and test on a scrap piece first to ensure a good seal.

While VAL55 bags offer exceptional moisture barrier properties, for optimal performance, especially with highly moisture-sensitive products or for long-term storage, it is strongly advised to use them in conjunction with desiccant sachets. This helps to absorb any residual moisture within the sealed environment.

Yes, the VAL55 material can be used for vacuum packaging, ensuring a tightly sealed environment that further minimizes the presence of oxygen and other atmospheric contaminants around your product.

Valdamark Direct advises that this material should be handled and used by appropriately trained professionals, especially when operating heat-sealing equipment, to ensure safety and proper application.

Beyond the correct temperature and dwell time, ensure the sealing area is clean and free of any dust, debris, or product particles. A clean sealing path is crucial for an airtight and durable seal.

The standard VAL55HD™ commercial construction is a sophisticated five-layer laminate consisting of 12µm PET, 12µm PE, 7µm Aluminium, 20µm PE, and 60µm HDPE, providing its market-leading barrier properties.

Once properly heat-sealed, VAL55 bags achieve an ultra-low water vapor transmission rate (WVTR), creating an optimal environment for sensitive items and ensuring long-term protection against moisture ingress.

Yes, the VAL55HD™ material is manufactured to conform in full to the UK Ministry of Defence standard DEF STAN 81-75. For US military specification MIL-PRF-131K Class 1, Valdamark offers other specific materials like VAL59HS™ or VAL131HD.

The VAL55 material displays excellent bond strength between each of its laminated layers, which contributes significantly to its overall durability, robustness, and barrier integrity.

Yes, this alu foil packaging is designed to maintain its performance within a wide operating temperature range, typically from -40°C to +70°C, making it suitable for diverse environmental conditions during transit and storage.

The aluminium layer is absolutely critical; it provides an almost impermeable barrier against moisture vapor, oxygen, and UV light. It essentially acts as a "flexible tin can," sealing your products from external environmental elements.

While standard pre-cut sizes are available for immediate online ordering, Valdamark Direct specializes in bespoke solutions. They can manufacture custom sizes and formats, including those with tear notches for easy opening, depending on your specific requirements and quantity.

Custom foil pouch production usually has a lead time of 7-10 working days. If modifications or additional fittings like valves, zip-lock ports, or carry handles are needed, additional manufacturing time will be required.

Yes, if you require the VAL55HD™ material on a roll, Valdamark Direct offers it in various widths, mainly as 200-meter linear log rolls, allowing you to convert the material to your desired dimensions.

Valdamark Direct offers flexibility, with quantities available from as few as 50 pieces for stock sizes, making them accessible for both small and large-scale projects.

While the primary function of VAL55 is as a moisture and oxygen barrier, some foil laminates also provide a degree of static shielding due to the conductive nature of the aluminium layer. For critical ESD protection, specific static shielding bags designed to create a Faraday cage are typically recommended.

By providing superior long-term protection, VAL55 bags help prevent product damage and spoilage, which can significantly reduce costly returns, rework, and waste. This long-term product integrity often leads to lower overall packaging costs.

When properly heat-sealed and combined with appropriate desiccants, VAL55 bags can significantly extend the shelf life of dry goods, often for many years, by maintaining an extremely low internal moisture and oxygen level. The exact shelf life will depend on the specific product and storage conditions.
