Aluminum Foil—A Solution to Sustainability Challenges

Nov. 23, 2020

In striving for a more sustainable and responsible world, the aluminum foil industry provides solutions to many of today's environmental problems. The applications and uses of aluminum foil in daily life are beyond imagination: from aluminum foil packaging and household aluminum foil to semi-rigid aluminum foil containers, bottle caps and composite foil bags, and other extensive packaging and technical applications to cope with today's sustainability Sexual challenge.

Aluminum foil characteristics

Aluminum foil is a versatile and effective material, involving many applications-especially packaging and technical products. If you are interested in the actual situation of aluminum foil or its application market, you can pay attention to the information part of aluminum foil.

1. Resource efficiency

Thinner aluminum foils that use fewer materials have been in the development process. This type of aluminum foil addresses the strong demand for sustainable production—especially in the packaging sector. Life Cycle Assessment (LCA) studies have shown that aluminum foil packaging and household foils account for less than 10% of the environmental impact in the product life cycle.

2. Clean and hygienic

Due to the high-temperature annealing process, the aluminum foil is completely sterile. It is safe to contact with food, aluminum foil will not maintain or promote the growth of bacteria. Uncoated aluminum foil will not react with most foods.

3. Security

Aluminum foil is safe when in contact with food. Uncoated aluminum foil will not react with most foods. In many applications, aluminum foil has no contact with the product because it is used in combination with other materials. In addition, aluminum foil is an ideal material to prevent product tampering and support anti-counterfeiting functions.

4. Reflection characteristics

Aluminum foil can reflect 98% of light and infrared. The bright surface also has low heat emissivity. This helps save energy during the barrier process. Its insulating function extends to fire protection. In the "firewall" of vehicles and ships, as well as in fire doors and building panels, aluminum foil can dissipate heat and prevent access to the oxygen needed to initiate a flame.

Sustainability and aluminum foil

1. Less material consumption-less environmental impact

Aluminum foil has particularly lightweight and also has the ability to combine with other materials, which all benefit from the many characteristics of aluminum foil. It can use the least materials, design high-performance packaging products, and use aluminum foil flexible packaging. Compared with rigid packaging, it has a higher product-to-package ratio and can use less material space and less energy for transportation. Reduce the use of resources, resulting in a reduction in the overall environmental impact and an increase in profitability.

2. Product protection-reduce food waste

Aluminum foil has excellent barrier properties, thermal conductivity, electrical conductivity, reflectivity, etc. These physical properties bring more protection to the product, reduce the energy required for cooling, and extend the shelf life of the product. Protecting food from degradation means less food waste and ultimately greater resource efficiency. After all, people have realized that food loss and waste is equivalent to wasting resources, including water, land, energy, labor, and capital resources. Unnecessarily generating greenhouse gas emissions will lead to global warming and climate change. As a responsible participant in the global food value chain, the Global Aluminum Foil Manufacturers Initiative, GLAFRI, supports and participates in the "Save Food Initiative" and is committed to encouraging innovation, discussion, and development of solutions to prevent food waste on a global scale.
