High purity aluminum is a very thin sheet formed after many calendering, which is an excellent heat conductor and light shield.
1.Good mechanical properties, can meet the use requirements of automatic packaging machinery, but lack of softness. Low tearing strength, easy to break at the fold. Easy to process, can be combined with plastic film, paper and other packaging materials and easy to color and printing.
2.Light weight, conducive to reduce transportation costs.
3.No thermal bonding, acid and alkali resistance, easy to crimp.
4.With metallic luster, good shading, strong light reflection ability, reflective rate up to 97%.
5.It is not easy to be corroded, good barrier, moisture-proof and waterproof, strong air tightness, and has aroma retention.
6.The shape is stable at high and low temperatures and does not expand or shrink when the temperature ranges from -73 to 371°C.
