AL55HS 25KG Aluminium Foil Bags: Reliable Packaging for Demanding Applications

The VAL55HS 25KG Aluminium Foil Bags are designed to provide top-tier protection for products across industries like aerospace, automotive, electronics, and medical equipment. These bags combine durability, advanced barrier properties, and ease of use, making them a trusted choice for safeguarding sensitive materials.

Material Composition and Structure

These bags are made with a sophisticated multi-layer structure (PET12/AL8/OPA15/PE130) that ensures maximum protection against external factors like moisture, oxygen, and light. Each layer serves a specific purpose:

• PET12 (Polyester Film): A 12-micron outer layer that offers strength, clarity, and serves as a great surface for printing.  
• AL8 (Aluminium Foil): An 8-micron layer that acts as the primary barrier, keeping out light, oxygen, and moisture to preserve product quality and extend shelf life. 
• OPA15 (Oriented Polyamide): A 15-micron layer that enhances the bag’s strength and resistance to punctures, ensuring durability during handling and transport.  
• PE130 (Polyethylene): A thick 130-micron inner layer that provides excellent heat-sealing properties and additional moisture protection.  

This multi-layer design results in a total thickness of 0.175 mm (±10%), striking the perfect balance between protection and material efficiency.

Dimensions and Capacity

The VAL55HS foil gusset bags are built to hold up to 25KG of material, with precise dimensions to ensure consistency and efficient storage:  

• Length: 880 mm (Tolerance: <400 ±3 mm, ≥400 ±5 mm)  
• Width: 395 mm (Tolerance: ±2 mm)  
• Gusset Width:110 mm (Tolerance: ±10%)  

These dimensions make the bags suitable for a wide range of packaging needs while optimising storage space.

Performance and Physical Properties

The VAL55HS bags are engineered for reliability, offering impressive physical properties: 

• Release Strength: ≥2.5 N/15mm, allowing for easy opening without compromising the contents.  
• Heat Seal Strength: ≥40 N/15mm, ensuring a secure seal that prevents leaks or contamination during transport and storage.  
• Pressure Resistance: Designed to withstand pressure changes without rupturing, making them ideal for air freight or other demanding conditions.  
• Drop Performance:The bags maintain their integrity even when subjected to drops, ensuring the contents remain safe under tough handling conditions.  

Key Features and Benefits

These aluminium foil bags offer a range of advantages that make them stand out in the packaging industry:  

• Exceptional Protection: The multi-layer structure provides a superior barrier against moisture, oxygen, and light, keeping contents fresh and safe.  
• Lightweight Yet Strong: Despite their robust construction, the bags are lightweight, reducing shipping costs and making them ideal for industries like aerospace and automotive.  
• Secure Heat Sealing: The PE layer ensures a strong, airtight seal, preventing contamination and maintaining product quality.  
• Durable Design: The bags resist punctures and perforations, even at sharp corners, ensuring the safety of the contents.  
• Sustainability: Their efficient material use and lightweight design contribute to a lower carbon footprint.  
• Premium Appearance: The sleek design and high-quality materials give the bags a professional, high-end look.
