Release time:2019-07-03
Calculation method for the unit price of packaging bags.
1. First, calculate the weighted average cost of the composite flexible packaging material
That is, calculate the total material cost based on the material structure and the cost of each layer of material, excluding processing costs and other miscellaneous costs.
A simple formula can be used here: a*Y%+b*y%+c*L%+……= TC.
Where a, b, and c represent the cost of each single-layer material constituting the composite material. Y, y, and L represent the proportion of each single-layer material in the total material weight. Remember that this is not the ratio of the thickness of each layer, because the density of various materials is different, so the weight and thickness are not proportional.
TC (Total Cost) here represents the simple total cost. Also, the number of layers is not necessarily only three; there may be more, but the calculation method is the same, except that there are more items.
2. Estimate the average cost of various processing technologies
Including various compounding, printing, coating, slitting, and bag-making processes.
It is difficult to accurately assess the specific processing costs of these processes in detail. Fortunately, the proportion of these processing costs in the overall product cost structure is not very large, so some errors in the estimation are acceptable.
3. Costs such as various management fees, taxes, and profits
This is also an important factor in the total cost of flexible packaging materials. Although the content is not complicated, the fluctuation range between different cases is too large, and it is difficult to say it in one sentence, but it can still be summarized in one sentence: The highest price is reasonable, and the lowest price is reasonable.
As for how to understand this sentence, everyone can use their imagination. Of course, it also includes common phenomena in the domestic market economy environment, such as commercial public relations, cutting corners, and using inferior materials as substitutes for superior ones.
