Aluminium plated bag is a high-performance packaging material, which is made by vacuum evaporation technology to uniformly coat a very thin metallic aluminium layer on a plastic film substrate, which is subsequently combined with other functional films such as polyethylene (PE), polypropylene (PP) or polyester (PET) through the laminating process, to form a multilayer structure of the bag. This process not only retains the flexibility, transparency and sealing properties of the plastic film, but also gives the metallic aluminium its barrier properties, gloss and good protection against light, gas and moisture.
Features
- High barrier performance: Aluminium plating layer can effectively block oxygen, water vapour and ultraviolet rays in the air, protecting the contents from oxidation, moisture and light, and prolonging the shelf life of the product.
- lightweight and cost-effective: compared with pure metal packaging, aluminium composite bags are lighter and less costly, while maintaining the main advantages of metal packaging.
- Aesthetics: Aluminium surface glossy and bright, can enhance the visual effect of packaging, while supporting a variety of printing methods to meet the needs of personalisation and branding.
- weather resistance: good cold, oil and high temperature resistance, suitable for transport and storage under different environmental conditions.
- Easy sealing and convenience: the inner PE film provides excellent heat sealing performance to ensure the strength and sealing of the seal, and some products are designed with self-adhesive strips or easy-tear strips for easy opening and resealing.
- Special features: such as anti-static aluminium bags, can effectively avoid static electricity accumulation, protect electronic components and precision equipment from static electricity damage.
Appkications
- food packaging: widely used in tea, coffee, nuts, snack foods and other dry food packaging, can effectively maintain the freshness and aroma of food.
- pharmaceutical packaging: using its moisture-proof, light shielding and high barrier properties, suitable for long-term preservation of drugs, health care products, to ensure the stability of the efficacy of the drug.
- electronics packaging: anti-static aluminium bags are ideal for packaging electronic components, circuit boards and other sensitive electronic products, to protect the product from static electricity damage.
- cosmetic packaging: to provide a high-level sense of appearance while protecting cosmetic ingredients from external factors to extend shelf life.
- industrial packaging: suitable for industrial raw materials, chemical products, etc. that need moisture-proof and antioxidant protection.
- daily chemical products packaging: such as laundry detergent, cleaning agents, etc., aluminium composite bags can effectively prevent the contents of moisture deterioration, to maintain product quality.
