How to calculate the cost price of a plastic product?

The formula for calculating the material cost of a plastic bag: length x width x number of layers x thickness x specific gravity x price = material cost.

Example:

Double-layer 40CM long, 30CM wide, 4-wire PP material, 14,600 yuan per ton

The material cost of each bag is: 0.4 (length) × 0.3 (width) × 2 (layers) × 0.04 (thickness) × 0.91 (specific gravity) × 14.6 (unit price per kilogram) = 0.1275 yuan.

Expanded information:

Plastic compared with other materials, there are the following aspects of the performance characteristics:

1. Lightweight

Plastic is a lightweight material, the relative density distribution in the 0.90 -2.2 between. Obviously, can plastic float to the surface? Foamed plastics, in particular, are even lighter because of the micropores inside, with a relative density of only 0.01. This characteristic allows plastics to be used in the production of products that require a reduction in self-weight.

2. Excellent chemical stability

The vast majority of plastics on acid, alkali and other chemicals have good corrosion resistance. In particular, commonly known as the plastic king of polytetrafluoroethylene (F4), its chemical stability is even better than gold, placed in the "aqua regia" in the boil for more than ten hours will not deteriorate. Because F4 has excellent chemical stability, is the ideal corrosion-resistant materials. Such as F4 can be used as a corrosive and viscous liquid pipeline materials.

3. Excellent electrical insulation properties

Ordinary plastics are bad conductors of electricity, its surface resistance, volume resistance is very large, with a figure of up to 109-1018 ohms. Breakdown voltage is large, dielectric loss angle tangent value is very small. Therefore, plastics have a wide range of applications in the electronics industry and mechanical industry. Such as plastic insulated control cables.
