Don't zip lock anything G1 with stickers. You run the risk of trapping moisture in the zip lock bag and over time the stickers may attract fungal growth in the form of tiny lines that look like veins.
I keep my transformers in storage in cardboard or plastic containers with a few silica gel satchels.

Bubblewrap works well, provided that it's clean.
