Aluminium-plastic composite pouch, as a modern packaging material, is high-performance pouch formed by laminating and combining aluminium foil with a variety of plastic films (e.g. PE, PET, nylon, etc.) through advanced laminating technology. This material combines the excellent barrier properties of aluminium with the flexibility and sealing properties of plastic to form a packaging solution that is both lightweight and durable. Aluminium composite pouches are often designed to include multi-layer structures to meet the multifaceted needs of different items for protection against moisture, oxidation, UV rays, tearing and to maintain product freshness.
Features
- High barrier: The aluminium foil layer provides excellent barrier to oxygen, water vapour and light, effectively extending the shelf life of perishables such as food and pharmaceuticals.
- strength and toughness: the composite structure gives it good mechanical strength, puncture and abrasion resistance, suitable for load-bearing packaging.
- Light and UV protection: the aluminium layer can effectively block ultraviolet rays and protect the contents from light damage, especially suitable for packaging of light-sensitive products.
- anti-static: the specific composite process can be given anti-static properties, suitable for the safe packaging of electronic components and other sensitive products.
- Printing suitability: the surface of the plastic layer is easy to print, making the packaging appearance colourful, conducive to brand promotion and product identification.
- Cost-effectiveness: compared with other high-end packaging materials, aluminium-plastic composite bags in the quality assurance at the same time, the cost is relatively low, cost-effective.
Applications
Aluminium composite bags have been widely used in many industries due to their unique performance advantages:
- food industry: commonly used in tea, coffee, milk powder, spices, pet food and other packaging, especially aluminium-plastic composite cooking bags, can withstand high temperature sterilization process, to ensure food safety and extend the shelf life.
- medicine and health care products: used for drugs, health care products, medical devices, aseptic packaging, to ensure that the product is not affected by the external environment, to maintain the stability of the efficacy of the medicine.
- chemical products: for chemical raw materials, fertilisers, detergents and other packaging, to prevent leakage and protect the nature of the product.
- electronic products: for circuit boards, precision components to provide anti-static, moisture-proof packaging, to protect the integrity of the product in the transport and storage process.
- Agricultural seeds: seed packaging needs good moisture-proof and air permeability, aluminium-plastic composite bags can be customized design to meet this special need.
- daily consumer goods: personal care products, cosmetics, etc. are also commonly used in this type of packaging, both beautiful and practical.
