| Blister Poly Bag
Unit : 1000 Pcs | 1. PP/PE | PP Consumption = 2x1000xLxWxTxDgm+ 8% Wastage
Sample Calculation : (Say, L = Length of Bag = 100cm, W = Width of Bag = 50.cm, T = Thickness of Bag = 0.0005cm, D = Density of PP=0.90gm/cc) Therefore, Total PP Consumption =(2x1000x100x50x0.0005×0.90)x1.08gm=4860gm=4.86kg | |
| Printed Blister Poly Bag
(1 to 4 color) Unit : 1000 Pcs | 1. PP/PE
2) Flexoprint Ink 3) Thinner/Reducer | PP Consumption = 2x1000xLxWxTxDgm+ 10% Wastage
Sample Calculation : (Say,L= Length of Bag=100cm, W = Width of Bag = 50.cm, T=Thickness of Bag=0.0005cm,D=Density of PP=0.90gm/cc) Therefore, Total PP Consumption=(2x1000x100x50x0.0005×0.90)x1.10gm=4950gm=4.950kg 22 gm(With Wastage) 66gm (With Wastage) |
Note: Thickness of the poly bag should be of single sheet/ film.
For any value of L, T & W the total consumption of raw material for 1000 pieces of poly bags can be estimated by above general formula for a define type of bag by following the method shown in the sample calculation.
Conclusion
For LDPE, D = Density = 0.91 gm/cc & FOR LLDPE, D = Density = 0.92 gm/cc, For HDPE, D = Density = 0.94/cc and for PP, D = Density = 0.90 gm/cc of pp film blowing machine
