Alumīnija folija ir karsts štancēšanas materiāls, kas tiek tieši velmēts metāla alumīnija loksnēs. Tā kā alumīnija folijas karstās štancēšanas efekts ir līdzīgs tīra sudraba folijas efektam, alumīnija foliju sauc arī par viltotu sudraba foliju. Alumīnija folija ir mīksta, kaļams, un tam ir sudrabaini balts spīdums. Tam ir arī vieglāka tekstūra, thanks to the lower density of aluminum foil.
Aluminum foil has various alloy specifications. Is the density of aluminum foil the same among different alloys? Common aluminum foil alloy models include:
The 1000, 3000, 5000 un 8000 series of aluminum foils have many differences in chemical elements, so the density will also be different. The following table shows the density of different aluminum alloy foils.
Low-density aluminum foil, such as that made from alloy 1235 vai 1350, offers several advantages: The low density of aluminum foil brings lightness to aluminum foil, so aluminum foil also has many advantages in various applications.
Viegls: Low-density aluminum foil is lightweight and easy to handle and transport. This feature is particularly useful in packaging applications, where minimizing weight can reduce shipping costs and increase efficiency. Piemēram, aluminum foil is used for food packaging and pharmaceutical packaging.
Cost Effectiveness: Because aluminum foil is less dense, less material is needed to achieve the same coverage or thickness than higher density foils. This can result in cost savings, especially in large-scale production and packaging operations.
Good Flexibility: Low-density aluminum foil is highly flexible and conformable, allowing the aluminum foil to easily wrap objects with irregular shapes or contours. This flexibility makes aluminum foil ideal for packaging applications where the foil needs to adhere closely to the contents, provide protection and maintain freshness.
Good insulation: Although low-density aluminum foil is lightweight, it still has excellent thermal insulation properties. It reflects heat effectively, making it suitable for applications such as building insulation, HVAC systems and thermal packaging.
Strong barrier properties: Low-density aluminum foil can effectively block moisture, gas, light and odor, helping to maintain the quality and freshness of packaged products. This makes it suitable for a wide range of packaging applications, including food, pharmaceuticals and cosmetics.
Environmental protection: As a recyclable material, aluminum foil’s low density makes the recycling process more efficient. Recycling aluminum foil not only reduces the amount of landfill waste, but also reduces energy consumption and carbon dioxide emissions, contributing to sustainable development.
The advantages of low-density aluminum foil make it a versatile and cost-effective material for a variety of packaging, insulation and thermal management applications.
