Laminated aluminium foil is produced by bonding aluminum foil to one or more substrate materials. The layers form a strong and flexible barrier sheet used for packaging and protection.
Main Features
- High moisture and oxygen barrier
- Good heat resistance
- Lightweight and flexible
- Printable surface
- Corrosion-resistant
- Suitable for food contact
Types
Laminated Foil with PET
A structure combining aluminium foil + PET film, offering good stiffness and high temperature resistance.
Use: food packaging, retort pouches, cosmetic sachets.
Laminated Foil with PE
A soft laminated foil made of aluminium foil + PE film, flexible and heat-sealable.
Use: bags, medicine packaging, dairy packaging.
Paper Laminated Aluminium Foil
Aluminium laminated with paper for extra strength and printability.
Use: cigarette packaging, labels, household packaging.
Multi-layer Laminated Foil
Three to five layers: PET + aluminium + PE / CPP / adhesive.
Use: heavy-duty bags, liquid packaging, industrial insulation.
