aluminium foil

In the processing and application of aluminium foil, precise control of the inner and outer diameters is key to ensuring production efficiency and product quality.

1. Inner diameter: precise matching, smooth production

Definition: I.D. refers to the diameter of the core of the inner tube of an aluminium foil roll.

Importance: If the inner diameter is too small, the foil roll will not fit smoothly on the machine, which will affect the production schedule.

2. Outer diameter: Stable operation, avoiding wastage

Definition: The outer diameter is the overall diameter of the aluminium foil roll.

Importance: A large outer diameter can lead to burrs on the edges of the aluminium foil during operation, which affects product quality and increases wear and tear.
