According to Taizhou Wanbangde Machinery Co. , Ltd. Providing the bearing’s outer diameter 9 cm ,height 2.2 cm;

The Laminated film(OPP/CPP)’s market price is 2.8USD. Laminated film(OPP/CPP) ’s thickness 45 microns and density is 0.9 g/cm,

The calculation formula of each packing bag’s unfolding film width and length:

Packaging film width’s calculation formula is width plus height multiply two and then plus two point four.

So final packaging film width is nine plus two point two multiply two and then plus two point four equals to twenty

four point eight cm.

Packaging film length’s calculation formula is length plus height plus two cm plus zero point six cm. So the final

length is nine plus two point two plus two plus zero point six equals to thirteen point eight cm.

The calculation formula of each packing bag’s unfolding volume.

Packaging film volume’s calculation formula is length multiply width multiply height.

So the final volume is twenty four point eight multiply thirteen point eight multiply zero point double zero three

five equals to one point one nine seven eight four cm³

The calculation formula of each packing bag’s mass(gram weight) as follows:

calculation formula is m is ρmultiply V.

so m is 0.9g/cm³x1.19784cm³ equals to 1.078056g.

The calculation formula of About how many bags per kilogram as follows:

1000g divide 1.078056g equals to 927 (about)

The calculation formula of each packing bag’s about cost as follows:

2.8USD/divide 927 equals to 0.003USD

The calculation formula of each bearing packing bag’s overall dimensions as follows:

Bag length is 9.0cm plus 2.2cm plus 2.0cm plus 0.4cm equals to 13.6cm

Bag width is 9.0cm plus 0.3cm equals to 9.3cm

Bag height is 2.2cm plus 0.2cm equals to 2.4cm

According to your company’s providing bearing of 9 cm diameter and height 2.2 cm, throughing the cost calculation of the packaging film, the cost is 0.003USD each bag. Even though add with electricity and printing plate making fee, is about 0.005USD.
