How to choose aluminum foil for packaging?
Aluminum foil has become one of the preferred materials in the food, pharmaceutical, and electronics industries due to its high barrier properties (oxygen/moisture/ultraviolet), temperature resistance (-50℃~300℃), and environmentally friendly and recyclable properties. As a leading company in the production and sales of aluminum foil, Fliat Aluminum is committed to providing customers with accurate material selection suggestions. However, aluminum foils of different alloy grades will affect their performance and application scenarios. The following is based on international standards (AA/GB) to sort out key grades, parameters, and applicable fields to help you make efficient decisions. Aluminum foil grades and core characteristics The performance of aluminum foil is determined by the alloy composition and processing technology. The following is a scientific classification of common grades: 1xxx series (pure aluminum foil, such as 1235 aluminum foil, 1060 aluminum foil) 🔹 Characteristics: aluminum content ≥99.35%, excellent ductility, strong barrier properties, and high corrosion resistance. 🔹 Parameters: Thickness range 0.006~0.2mm, water vapor transmission rate <0.015 g/(m²·24h), tensile strength 80-150 MPa. 🔹 Application: food packaging (chocolate, dairy products), pharmaceutical blister packaging, etc. 3xxx series (aluminum-manganese alloy, such as 3003 aluminum foil) 🔹 Features: Add 1.2% manganese element, the strength is increased by more than 30%, the...
