Commercial Aluminum Foil is an ultra-thin aluminum metal material made by precision rolling. The core advantages of this aluminum alloy foil are light weight, heat resistance, and strong barrier properties. It is widely used in food, construction, electronics and industrial fields. The following is an analysis from the technical parameters, application scenarios and brand recommendations.
1. Core performance and advantages
Thickness range: The thickness of jumbo roll aluminum foil is generally {{0}}.006-0.15mm, and industrial-grade products can reach more than 0.1mm, with a tensile strength of Greater than or equal to 80MPa; Surface characteristics: Aluminum foil jumbo roll is divided into Mill Finish aluminum foil or double-sided bright aluminum foil, with a heat reflectivity of 70%-90%, suitable for high temperature scenes; Barrier properties: The water vapor permeability of aluminum waterproof tape made of waterproof aluminum foil is Less than or equal to 0.1g/(m²·day), and the oxygen barrier efficiency is Greater than or equal to 99.5%.
2. Application scenarios and suitable grades
Scenario: baking, cold chain transportation, aseptic packaging of pre-prepared dishes;
Recommended grades: 1235-O-state aluminum foil (purity 99.35%+, elongation Greater than or equal to 20%), resistant to oil penetration and suitable for special-shaped packaging.
Recommended grades: {{0}}H18 insulation aluminum foil (containing iron reinforcement layer, thickness 0.03-0.1mm), tensile strength Greater than or equal to 100MPa, salt spray resistance 500 hours.
Scenario: 5G base station cable shielding, precision component moisture-proof;
Recommended grades: 3003 precision aluminum foil manganese reinforced alloy, withstand voltage 5kV, flame retardant grade UL94 V-0.
3. Selection and purchasing suggestions
High temperature scenarios: give priority to 8079 aluminum foil (temperature resistance 200 degree +) or anodized coating models (resistant to 660 degree ); Certification requirements: Food-grade aluminum foil must comply with FDA standards, and industrial-grade aluminum foil must pass ISO 9001 and RoHS certification;
