I have some cookies that I'd like to ship. Is there a specific shrink wrap that you've got to use? Does it make your cookies taste a specific way? I got a shrink wrap bag that I bought in the craft section at Walmart, but I'm unsure. Should I wrap the cookie in saran wrap first and then the shrink wrap? Sorry for so many questions...just trying to figure this out. It's my first time shipping cookies! 
Clear food grade polyolefin shrink wrap:

Royal 80 gauge shrink bags, food grade and non-food grade:

Food grade shrink wrap is more expensive than non-food grade so yours is probably for use with craft items (unless it's marked food grade).
If I were you, I would wrap in Saran Wrap and then the shrink wrap.
