Noob question about plywood coming apart

[sofa_king_rad]

Most work I'd done till now was just mdf.

I went through my plywood to find a piece big enough that I could cut it down to use for two panels so that the grains were similar. I found one piece that was perfect.  Are my first rip down cut and big section of the plywood was loose and unglued.

Is this a common issue?

Totally depends on the source of the plywood...there is a lot of dodgy material out there so you need to find a supplier who only stocks quality material.  I use a plywood supplier who primarily serves commercial users like cabinet shops and I have never had an issue.

How many plies is it made of? The higher the number the more stable and strong.

I use only Baltic Birch from a very reputable supplier. Never found a void and never had a delamination. The surfaces are paintable or stainable with very light sanding with 220 grit.

...

Stable = yes.
And more consistent strength = yes

But even coming apart at the plys, the tensile strength is probably the same as any other.

That said, most people like the Baltic birch ply. And the bending strength/modulus would be a lot better.

  Most of the time the plywood will start to separate if it's left sitting on concrete. The moisture will get in between the plys and just wreak havoc.
On occasion I have found it to be a manufacturing defect, usually that's when I buy sheets from the big box store or a local building supply company (which I will no longer use for sheet goods) that sells plywood made in China.

Okay, I'll look at the place where I got my hardwood for ply next time. I will also drop some slats on the concrete where's my wood is sitting. I have a lot of organizing to do in my work space.

As you build more projects, you will get pickier about your materials. I used to use whatever was cheapest, but I have gotten comfortable with the quality and price of more expensive lumber and can't easily turn back.

I was honestly just concerned out the formaldehyde thing. I would have happily paid more if I had know of other good options.

I built a rolling cart to store scraps.  It gets things off the floor and lets me store a lot more in the available space. 

I've been using $30/sheet pine plywood from Home Depot and need to go pick up another sheet for a cabinet to go into a bathroom.  You won't see it unless you pull a drawer, it will go into an alcove.  It has very view voids but is interior glue.  I'll put at least a couple coats of wipe on poly on it before installation.  Not everything at the big box stores is bad.  I've been disappointed too.  I need some 1/2 for the drawers and I am not sure where it will come from.  I like Baltic birch but that supplier is only open during the week.  I may just staple the drawers together (this is for an infrequently used bathroom) and I would hate to do that to bb, however.  I might just use sandeply.  When I've used it before it was not bad about voids or delamination but it is soft.
