My drink package


Food product packages are terrific to analyze for DfE.

What about that beverage you just had? How does it stack up in product weight to package weight, one great way to assess packaging $ costs and environmental costs.

Here's some data

Product Content (gms) Container (gms) Container material Content/Pkg weight
can of coke 355 16 aluminum 22
gallon of milk 3780 66 HDPE 57
64 oz. cranapple juice 1890 100 PETE 19
1.5L water 1500 40 PETE 38
bottle of wine 750 608 glass 1.2

 

Assumptions: All drinkable liquids have the same density as water. If you want to expand on this table some useful conversion factors for water are: 1 fl. oz. = 1 oz., 1 lb. = 2 cups, 1 gallon = 8 lb., 1 oz. = 28.35 g, 1 qt. = 0.946 L, 1 L = 33.814 fl. oz., 1 L= 1 kg
