Do to the nature of my job, my family is moving a lot. Almost like clock work, every 18-24 months I am transferred to a different military base. While moving so much is stressful, there are a few things that always makes our moves smooth and easy. BY FAR, the number ONE packing essential is Duct Tape's 3.1mil Packing tape. There is nothing worse than running out of tape, or having a box break on you. With 3.1mil thickness, you use less tape (not having to tape the bottom 3-4 times as with thinner tape), and you know the tape is super strong so you don't have to worry about your box breaking. With every move, there is always one super late night, packing until 3am session (I'm sure many can relate). When you can hardly keep your eyes open, you're sitting on the floor fighting the urge to just lay down, and you go to tape a box close. However, you usually have spend 3-5 mins trying to find the end of the tape. It is usually because the tape is splitting and splintering. What a nightmare. With the 3.1mil thicker packing tape you NEVER have this problem. It cuts clean, pulls of straight, and is worth every cent! We don't even think of moving with out it.
