What You'll Learn
Plastic is half the weight of aluminium
Plastic is about half the weight of aluminium. For example, a 500ml aluminium can weighs around 15 grams, while a plastic bottle of the same capacity weighs 19 grams. In terms of volumetric mass density, Teflon®, one of the heaviest plastic materials, has a density of 540 kg/m3, while aluminium has a density of 2,700 kg/m3. This makes plastic a lightweight and attractive option for packaging and transportation, as it helps reduce fuel and energy costs, emissions, maintenance costs, and logistical expenses.
Plastic's lightweight nature, coupled with its durability, mechanical properties, and ability to withstand various stresses, gives it a higher power-to-weight ratio than traditional materials like metal and glass. This makes plastic ideal for various industries, including transportation and aerospace, where weight reduction is crucial for fuel efficiency and performance.
While plastic has the advantage of being lightweight, it is essential to consider its environmental impact. Plastic pollution is a significant concern, and while plastic produces a lower carbon footprint than glass, it can release harmful chemicals as it disintegrates, posing dangers to the environment and human health. Additionally, plastic is not as heat-resistant as aluminium, limiting its use in certain applications, such as kitchen appliances.
On the other hand, aluminium is known for its durability and resistance to corrosion, oxidation, and fire. It is also infinitely recyclable without losing quality, making it a more sustainable option than plastic in the long run. However, aluminium is usually more expensive to produce than plastic, which is super cheap and widely available, making it challenging to replace plastic with aluminium on a large scale in the short term.
In conclusion, while plastic is about half the weight of aluminium, the choice between the two materials depends on various factors, including cost, availability, durability, heat resistance, health considerations, and environmental impact.

Aluminium is recyclable and more durable
Aluminium is a highly durable metal that can be recycled repeatedly without degrading its inherent value. It is composed of atoms bonded together and formed in a crystal structure, which makes it exceptionally easy to melt and reform into a solid state without changing its fundamental properties. This means that aluminium can be recycled over and over again, supporting a more circular and sustainable economy.
Aluminium is lightweight and strong, making it ideal for various industries, including automotive, building, and beverage packaging. It has a high strength-to-weight ratio, weighing up to 65% less than steel while providing comparable strength. This makes it a great choice for structures and vehicles, as it can help reduce weight without compromising safety or performance.
The recyclability of aluminium also contributes to its durability. Aluminium can be recycled repeatedly, and each time it is recycled, it only takes around 5% of the energy needed to produce new aluminium. This not only reduces carbon emissions but also saves money for businesses and consumers. The North American aluminium industry has made significant strides in sustainability, with a more than 50% reduction in its carbon footprint over the past 30 years.
Aluminium's durability and recyclability make it a popular choice for companies seeking to demonstrate a commitment to sustainability. For example, Apple has committed to using 100% recycled aluminium in its products, and Coca-Cola has announced that its aluminium packaging will contain up to 70% recycled content. However, it is important to note that switching from plastic to aluminium packaging can create new challenges, such as the need to increase recycling rates to avoid sending more aluminium to landfills.

Plastic is cheaper to produce and more available
Aluminium is a lightweight material, with an average 500ml aluminium can weighing around 15 grams, compared to 19 grams for a plastic bottle. Aluminium is also durable, reusable, and resistant to corrosion, fire, and impact. However, plastic has certain advantages over aluminium.
Furthermore, plastic is versatile and can be used in various applications, from packaging to toys and appliance housing. This versatility drives demand and makes plastic a popular choice for manufacturers. The high demand for plastic, coupled with its low production cost, creates a cycle where companies increasingly rely on plastic to reduce their costs and increase profitability.
However, the widespread use of plastic comes at a significant environmental cost. Plastic is not widely recycled, and the recycling process itself can be challenging and expensive due to the need to sort and separate different types of plastics. While technologies exist to recycle plastic at the molecular level, creating a pure stream of recycled material remains a challenge. As a result, most plastic ends up as waste, causing severe pollution and long-term damage to the planet.
In summary, plastic's cost-effectiveness and availability make it a popular choice for manufacturers and contribute to its widespread use. However, the environmental consequences of plastic pollution are severe, and addressing them will require a collective effort to reduce plastic consumption and improve recycling practices.

Aluminium is safer for food storage
Aluminium is a lightweight, durable material that is widely used in kitchen appliances and outdoor products. It is known for its ability to withstand harsh conditions, including weather, corrosion, fire, and impact. These qualities make it ideal for food storage and transportation.
Aluminium is a safe and sustainable alternative to plastic for food storage. It is a good conductor of heat, allowing for even cooking and preserving the moisture of the food. Aluminium trays provide a 100% water and gas barrier, making them perfect for storing and preserving food. Additionally, aluminium is infinitely recyclable without losing quality, making it a more environmentally friendly option than plastic.
While some people express concerns about the potential health risks of using aluminium foil in cooking, researchers have found that the amount of aluminium that seeps into food during cooking is very small and safe. The European Food Safety Authority, for example, provides conservative estimates of safe usage. Nevertheless, it is recommended to reduce the use of aluminium foil, especially when cooking with acidic foods, as a precautionary measure.
In comparison to plastic, aluminium poses significantly fewer risks for food storage. Plastic degrades over time and is not heat resistant, limiting its durability and kitchen use. Plastic packaging is also a major contributor to environmental waste, with companies favouring its cheap production costs and ease of packaging for single-use items. However, aluminium's recyclability and durability make it a more sustainable and cost-effective choice in the long run.

Plastic is not heat-resistant
When it comes to the weight of plastic versus aluminum, aluminum is the clear winner in terms of lightweight material. A 500ml aluminum can, for instance, weighs around 15 grams, while its plastic counterpart weighs 19 grams. However, the discussion of plastic versus aluminum goes beyond weight considerations. One critical aspect is heat resistance, where plastic falls short.
Plastic is not inherently heat-resistant, and its ability to withstand heat depends on various factors. Firstly, different plastics have different heat resistance properties. For example, polypropylene has a low heat resistance and starts to lose strength at 180°F (82°C), while polyethylene can handle temperatures up to 266°F (130°C). The type of plastic and its specific composition play a significant role in its heat resistance capabilities.
The intended use of the plastic is also important. Some applications require continuous exposure to high temperatures, while others involve short-term heat exposure. Heat-resistant plastics are generally defined as those with a continuous-use temperature above 150°C (302°F) or a short-term exposure resistance of 250°C (482°F) or higher. This distinction is crucial when selecting a suitable plastic for a particular application.
Additionally, load conditions, corrosive environments, and thermal expansion properties can impact a plastic's heat resistance. These factors can alter the mechanical and thermal properties stated on a data sheet, emphasizing the need for careful consideration when choosing a heat-resistant plastic for specific applications. It's worth noting that even before the plastic reaches its melting temperature, its molecular structure can change, affecting its properties.
While some plastics, like PAI (Polyamide-Imide), can withstand temperatures up to 270°C (518°F) and offer excellent mechanical and chemical resistance, they are still limited in certain high-temperature applications where metals or other materials may be more suitable. This limitation in heat resistance is one of the factors that influence the choice between plastic and aluminum for various products, especially in the kitchen, where durability and heat resistance are essential.
