Here is a link for important info about packing and shipping, and the customs form (which will double as your shipping label). NOTE - in Box 10- if non-deliverable, check "redirect to address below" and add "any local chaplain".
Please use a FREE Military Flat Rate Large box- available from the Post office- also get a customs form while you are there. This box costs $11.95 to ship no matter the weight and is usually much less expensive than any other box.
Add a card, as you would to a pen pal! Also, on the mailing label include Operation Baking Gals along with your name and address in the "from" line. In addition to your customs mailing label, USPS asks that to soldier's name/address info also be written directly on the box.
Here are some more personal tips from a mom who sends goodies-"Most things such as cookies, muffins, cupcakes, loaf quickbreads, I use my Seal a Meal. I seal them as far as I can without smashing them. Then pack them in a box of styrofoam peanuts. Typical way of boxing them. Oh, I also FREEZE them first!! Just to make them last a few extra days. My son said he forgot about some muffins once for 3 weeks since they were out on a mission, and they were just as fresh as freshly baked! So I don't know if it was the Seal a Meal or not. But I would say just pack them as protected as possible. Don't bother to send anything chocolate as it will melt no matter how you try it.
With the seal a meal, everything somehow is compact and able to layer things easily. So that's how I do it. Without it, it'd be a lot of packing in layers of styrofoam wrappings
I freeze then after I seal them, that way I can stack them all up in the freezer to save space. I do a lot of baking on some days and process a bunch of stuff, and then when I send out a package I pull out whatever I have in there. I also seal and freeze things like Little Debbie treat, etc.
Oh, I also, eve though it's a lot more work, seal up like individual size package. Such as 6 cookies to a pack, or 2 muffins. So in case my son is passing something out or someone is there when he's opening a package, he can just toss them cookies, muffins without giving them ALL the goodies!."
Note- I used my food vac and sucked as much air out, before they started to smash. - but didn't freeze. Please remember to NOT send any pork products or meltables- chips in cookies seem to be ok at some times of the year, but when it is summer you may want to use candy coated chips as it gets quite HOT!
