does bubble wrap explode at 30,000ft?

[dellzeqq]

because I need to know!

 

[vernon]

Definitely not.

 

[longers]

It doesn't pop in one of these.* I think that the bubble walls leak slightly as the vacuum takes a couple of minutes to pull and prevents popping, a bit like a plane climbing to 30,000 ft would have the pressure decrease slowly in the hold.

* we couldn't get eggs to explode in there either.

 

[vernon]

Now the explanation. The pressure difference between sea level and 30,000 feet is about 10psi which will not compromise the bubble wrap. The pressure difference between inside and outside the bubbles will rise from 15psi to 25 psi.

All bubble wrapped items that have arrive chez Vernon via airmail have not had the integrity of their bubbles compromised.

But did it crush the contents?

 

[Zoiders]

No.

Never encountered it, never seen it go pop in the sun either.

Bubblewrap claim their own brand stuff is flexible enough not to leak.

atmospheric pressure at 30000' is approx 1/3 of that at sea level, but I presume you're talking about sending something fragile in a cargo plane, in which case it'll be fine as cargo holds on passenger planes and cargo planes are pressurised(to about 0.7bar IIRC) or the eqivalent of about 10000 elevation, so no probs I would have thought.

Mine didn't from Manchester to Lanzarote and back again

 

[dellzeqq]

excellent! Many thanks, one and all!

Or you can use Cheesy Wotsits.

Biodegradable packing and a tasty snack for the recipient.

As long as they remain bagged their tastiness will be unimpaired.

would not know or care

many other more important things in life than this to worry about

No idea but i do know a tennis ball crushes its self at about 50 mtr below sea level (sat in a Hyperbaric chamber and watched one do it , and when you talk it messes with your vocal chords and you sound like donald duck)

That's the helium and not the pressure.
