The pain properties of aluminum and its impact on human life

Net resource saver
Aluminum foil in food and beverage packaging applications saves more resources than its production requires. Various Life Cycle Assessments (LCAs) show that foil packaging and household foils contribute less than 10% of the environmental impact during the product life cycle (sustainable production and consumption).

Barrier protection
Alufoil’s comprehensive barrier to light, gas and moisture is the main reason for its flexible laminates for food, beverage and technical applications. Even very thin, it perfectly protects and preserves the aroma and product properties. It can help extend the effective life of sensitive products by months or even years, completely preserving the original aroma. By enabling products to be stored for long periods of time without the need for refrigeration, foil packaging helps prevent spoilage and can save a lot of energy.

Mechanical behavior
Lightweight yet strong, aluminum foil has unique dead-fold properties that make it ideal for packaging and repackaging many different products and product shapes, while minimizing the need for sealants. Because it is highly malleable, it can easily deform without losing its barrier integrity, making it ideal for use in combination with other flexible substrates to create very thin laminates for a variety of markets, Thereby again saving resources.

Formability and Strength
When pressed into a formed plate, the foil remembers its shape, especially where folds and edges appear. Shapes, thicknesses, alloys and tempers can be selected to create exactly the desired performance characteristics.

Lightweight and space saving
The economy of transport and storage comes from the light, flat or roll form of empty packs, and in the case of foil containers, their nested shape is particularly suitable for filling machine magazines. Aluminium foil helps save resources during packaging, product and waste transport. By enabling products to be stored for long periods of time without the need for refrigeration, foil packaging can save a lot of energy. Their shape allows them to be very “space efficient” for storage and display, resulting in further energy and cost savings. Alufoil reduces weight, is versatile and minimizes the amount of packaging material required.

Structural stability
In lightweight honeycomb structures, aluminum foil introduces the necessary stiffness and stability, enabling architects to reduce weight in building structures and foundations; and engineers, to reduce weight in all types of transportation – ships, planes, trucks and cars.

Aluminium is fully recyclable without any loss of quality. Compared to primary production, the recycling process of aluminium requires 95% less energy, which equates to substantial emissions savings. Modern separation technologies allow the extraction and recycling of aluminium foil from household waste at a fraction of the original energy cost.

If the aluminum foil is not collected for recycling, but disposed of in an incinerator, the thin laminated foil material will oxidize and release energy that can be recovered. In addition, the remaining non-alumina can be extracted from the incinerator bottom ash for subsequent recycling.

Thermal performance
Aluminum foil is very thermally conductive. It withstands all temperature changes encountered during packaging processing and use – from well below the extremes of blast freezing to baking and grilling – without the risk of warping, melting or bursting. Aluminum foil also dissipates heat quickly – ideal for autoclaving and heat sealing processes. It can help minimize sealing time and balance temperature gradients within containers and flexible packaging, helping to protect product quality and energy economy. Its thermal conductivity helps minimize processing, cooling and reheating times.
Crucial to the efficient operation of a vehicle’s powerplant as well as driver and passenger comfort, foil-finned heat exchangers provide cooling and heating as needed. Due to its light weight, aluminum foil has become the automatic choice.

Multi-mode heating or cooking
Foods in foil pans can be cooked, reheated or reheated by convection, microwave or fan ovens or “bain-marie” systems. Foil wrap helps save time and resources during preparation.

Once produced, the foil is completely sterile due to the high temperature annealing process. It is safe for food contact and does not breed or promote bacterial growth.

Safety and Product Safety
Aluminum foil is safe for food contact. Uncoated aluminum foil will not react with the vast majority of foods. In many applications, aluminum foil is not in contact with the product because it is used in combination with other materials in the laminate. In addition, it is ideal protection against product tampering and can support anti-counterfeiting features.

Decorative potential
Alufoil’s bright or matt metallic finishes and compatibility with all printing technologies give designers enormous scope to create packaging with stunning graphic designs, shelf presence and brand identity.

Aluminum foil reflects up to 98% of light and infrared heat. Bright surfaces also have low thermal emissivity. This helps save insulation energy. Its insulating effect extends to fire protection. In the “firewalls”, fire doors and building panels of vehicles and ships, aluminum foil can dissipate heat and prevent the oxygen needed to support flames.

Aluminum foil shields electromagnetic radiation and radio frequency radiation. Aluminum foil is used in fiber optic cables to act as a “tracer” to test the integrity of cable links. In cable wrapping, electrical conductivity verifies the integrity of the cable circuit.
