If I know the are going to a place that is particularly rough on eggs. Atlanta Georgia and Washington State are Notoriously bad. For regional inside CA I would not double box.
ok so if not double boxing i will just line the box with padding and put the eggs in bubble wrap like burritos/open end tubes, and then off they go. ok i think i got it. ive been shipping in cartons and some have been getting broken. i bubble wrap and place in carton then bubble wrap carton and into a box. im trying to find the best way possible because coming up i have some pretty valuable eggs that will be shipped.
I use two types of bubble wrap. The small to wrap the eggs and the big bubble wrap to make a " pillow" around the eggs. I also use foam peanuts or peas to fill in the bottom, sides and top spaces.
, but seem to work very well to cushion the eggs.
this helps a lot!
