Would this work on regular plastic drinking straws?

Yeah it works. You just have to use your head. You could also buy one of those crimped flat iron style seekers to do it and they only cost around $10 or less. If you’re going to do this you’ll wanna have some Heavy duty aluminum foil (or just double up the regular foil) between the sealer and the straws. You’ll be able to get a read nice seal that won’t separate and lead people trying to claim this or that. And lastly you could seal straws using a lighter and your fingers. This is quite fun, especially if the melted straw sticks to your skin!! But the cool thing about using your bare fingers is it’s the original crimp sealer that all other crimp sealers later copied. “ But how can that be you ask? They’s just flesh and bones?” Well the key is in your finger prints! When you have the straw good and melted quickly grab to tightly with a nice long firm pressure and then release. You’ll know it’s a perfect seal when your finger prints leaves ridges on the straw where you squished it together. If some straw sticks to you skin Like taffy that’s a sign of a great seal I guarantee it! You can also use your lips for a crimp marking going the opposite direction. Finally another option is your teeth! Front teeth from a fine seal similar to the typical 2mm heat sealer, incisors around a 3-3.5mm and the molars are around 6mm on average. Another trip is called the molar stack and that if you heat a long section and then bite down with the entire row available teeth on the left or right side of your mouth. This technique is very wasteful, especially in this day and age where we’ve become more straw conscious. In the past though the linear row chomping technique was use quite often be straw chewers for the purpose of nothing. They also would exclude the heating process and go directly to the biting which would result in never being able to make the seal work and thus they would chew and drool and just really accomplish little to nothing of value. Luckily these people have moved on to a much better practice if coca chewing and Betal chewing. In both cases they also add some slaked lime to the chewing in order to be able to absorb the alkaloids through a chemical reaction that takes place increasing the bio availability. How they leaned this is likely from ancient astronauts visitors long ago however despite the word astronaut being used it is now believed that they are inter dimensional travels rather than them come from above the earths plane and someone passing through the firmament which isn’t seen as possible at the present time.

What is the length of the sealing surface?

The sealing surface is exactly 6 inches (I have a tape measure :)

I was told the type of mylar bag I have needs a 350 degree heat. Is this reaching that heat?

Works very well on the dozen bags I used it on. I am sealing 6 gal mylar bags and it makes quick of it.
