The metal powder industry requires packaging solutions that ensure material purity, prevent oxidation or contamination, and maintain handling safety across storage and transport stages. Given the reactive, hygroscopic, and often fine particulate nature of metal powders, the choice of packaging material plays a critical role in preserving material characteristics.
In many cases, these bags are used as liners within fibre drums, metal containers, or bulk handling systems, depending on the material type and logistics requirements. The packaging may also be customized to incorporate anti-static properties, multi-layer laminations, or vacuum sealing, in line with handling and storage guidelines.
Commonly used packaging materials in this sector include:
Low-Density Polyethylene (LDPE)
Known for its chemical resistance and flexibility, LDPE is commonly used for packing APIs, intermediates, and fine powders.
High-Density Polyethylene (HDPE)
Offers higher strength and moisture resistance, making it suitable for heavier bulk drugs, granules, or materials sensitive to environmental conditions.
Tri-laminated Aluminium Foil
This multilayer structure (typically PET/Aluminium/PE) provides an effective barrier against light, moisture, and oxygen. It is widely used for packaging hygroscopic, volatile, or photo-sensitive pharmaceutical compounds.
Metallized Polyester (MPET)
Combines the properties of PET film with a metallized layer to offer light and vapor barrier performance. MPET bags are used for packaging materials that require moderate protection from external elements.
