Calculate film weight

Weight of a film roll

A = film width
B = film length
C = film thickness
D = film density

A × B × C × D = weight in kg

Example:

A = 1 m
B = 1,000 m
C = 100 µm or 100 x 10^-6 m
D = 922 kg / m³

1 m × 1,000 m × 100 × 10^-6 m × 922 kg / m³ = 92.2 kg

or simply:

1 m × 1,000 m × 0.1 mm × 0.922 kg = 92.2 kg
plus weight of the sleeve

Cover calculation

You can find a calculation guide to determine the correct fit of a cover here. The sketch shows the letters used in the calculation in relation to the sides of the cover to be calculated. The dimensions of the pallet require some allowance to fit the cover.

Variant 1: Side gusseted cover

The dimensions of a side gusseted cover are given as:

(X + Y) × Z

X = A + 50 mm
Y = B + 50 mm
Z = C + 150 mm + B/2

Variant 2: Flat sack

The dimensions of a flat sack are given as:

X × Y

X = A + B + 50 mm
Y = C + 150 mm + B/2

X is always the open side of a bag or sack!
