OK Folks, most people who use parafilm dont stretch it much as it does not stretch much either. On contrary, that 1.5 inch strip of buddy tape stretches to 8 to 10 inches. Adam explained earlier in another post, here it is again:
1. Take one strip off the roll
2. Stretch a 1/4" to 1/2" of strip slowly wrapping the scion, you will get blown away on how much it stretches before it snaps. go slow, once you use the stretched portion, grab the next 1/2" section and wrap, and stretch and wrap.
If you simply are using the buddy tape without stretching it, you are not doint justice to Buddy Tape on how its intended to be used. On 8" long scion, I use mere two strips, including tieine the union and completely wrapping the scion.
Those who know how to stretch and use, they can second my comment here.
