How to choose aluminum foil tape based on your needs?

1. Pure metal requirements: Choose unlined aluminum foil tape with an aluminum purity of ≥99% (such as 3M 425 series).

2. Composite requirements:

- Tear resistance required: Choose a PET-lined model (thickness 0.05mm or greater).

- Corrosion resistance required: Choose aluminum foil with a plastic coating (such as a fluorocarbon resin coating).

Additional advice: If used for food packaging, confirm that the adhesive meets FDA standards (e.g., no risk of plasticizer migration).
