This is for a box of 500 crystal clear polyolefin shrink bags in the XL 8"x12" size and 75 gauge thickness. The opening is on the 8" side. This gigantic size bag is great for all kinds of extra large items like giant bath bombs or small gift sets. You can also seal these lengthwise to make long tubes for bath bomb sets. You can also seal these lengthwise to make long tubes or smaller sections. These larger bags work great for small gift sets as well.
ABOUT POLYOLEFIN:
Polyolefin is a softer plastic than PVC. It shrinks without sharp edges and it’s ideal for bath & body products. Polyolefin requires a heat of 300-350 degrees to shrink, which means you have to use a heat gun. (PVC shrinks with just a hair dryer.) A hair dryer will not shrink polyolefin. See instructions below for using these bags.
Polyolefin protects products from the elements, dust and contamination, but your customers can still SMELL the product through the packaging. Just give your item 24 hours after shrinking to be able to smell it through the plastic. It takes a day or so for the scent to work it's way through the plastic.
This plastic is FDA approved and considered food safe as well. It’s a great product and it’s what we use on all our soaps, bath bombs, bubbly bath bars and more. Sometimes we tie off the end and use it as a bag for items we don't want shrink wrapped. 
Polyolefin shrinks easily and without the noxious fumes of PVC. It’s the ideal shrink bag for bath stuff! 
INSTRUCTIONS FOR USE- use an impulse sealer to seal the excess bag off, then shrink with a heat gun starting at the corners and seams, moving quickly so you don’t burn through. Don't focus heat on the flat surfaces or they'll burn through. Tighten seams and corners first and be quick over flat spots. It takes a little practice to figure it out, but the result is a clean, professional looking shrink wrap when you do! YouTube has how-to videos as well. 
TIP: We like Jorestech brand impulse sealers with the metal housing and Wagner 1200-1500watt heat guns. Both are available on Amazon.
Products are just an example of items we shrink wrap using these bags. These are not included in this listing.
FYI- If you choose the "padded flat rate mailer" we will ship these without the box they come in. They can ship cheaper this way, but if you care about having the box, please choose priority mail or medium flat rate box.
