Cost calculation method of food plastic packaging bag

Plastic bag cost price = raw material cost+worker cost+machine loss+operating cost.

Specific calculation method:

Suppose we need 5000 PP plastic bags with 50*60CM and 8 lines on both sides. The thickness of 8 lines on both sides is 4 lines on one side. Note: 100 silk = 1mm, the company has two blow molding machines and one printing machine 1 set, * * * 60,000 yuan, with a 6-year retirement period; The operation cost is 4500 yuan/month, 5 workers, and the construction period is 2 days.

Length * width * height * density * unit price = cost

Note: Length, width and height are in meters.

0.5 * 0.6 * 8/10000 * 910 *12 = 0.26208 yuan (raw material price)

Plastic bag price = raw material cost 0.26208+ labor cost 0.08+ machine loss 0.0 1 1+ operating cost 0.03.

The final result is: 0.38308 yuan.

The profit of the external processing factory is the price of ordering packaging.
