The Density of Plywood is higher than the density of the timber species used to manufacture the products .

The face/back veneers of plywood weight practically much less than the core veneers. So the density of plywood is mainly depended on the timer species of the core veneers .

Usually 4 kinds of timber species are used to manufacture the cores of plywood ( film faced plywood ) , i.e. birch, hardwood, pine and poplar. The density of different plywood is listed as follows:

PLYWOOD (FILM FACED PLYWOOD) DENSITY (KG/M3 or KG/CBM) 

BIRCH CORE PLYWOOD (FILM FACED PLYWOOD)

ABOUT 680~700

HARDWOOD CORE PLYWOOD (FILM FACED PLYWOOD)

ABOUT 580~620

PINE CORE PLYWOOD (FILM FACED PLYWOOD)

ABOUT 570~610

POPLAR CORE PLYWOOD (FILM FACED PLYWOOD)

ABOUT 500~530

 

Sometimes, buyers order combi core plywood , such as combined poplar/hardwood, combined birch/poplar and so on . The density of combi plywood is depended on the components of core .

It would be nice to know what thicknesses of plywood the above density quotes are for (1/8, 1/4,1/2?)

[...] Density is the only thing that will change and effect weight between the two types. Google: Birch Plywood density = ~690 kg/m^3 MDF density = ~750kg/m^3 So, you can take a ratio: 690/750 = 0.92 Perecentage multiplication = [...]

very useful information when sending by small trucks locally

for example 2500x1250x18mm=0.05625m3
the weight is 680kg/m3 x 0.0565 =38.25kg
can do the same for other thicknesses

Yes, but it’s approximate weight of sheets .
