will these work as shrink wrap? can I use a heat gun and shrink these bags to protect a book for shipping?

I've am not familiar with the shrink wrap process, but have you tried using a regular gallon storage zipper (Ziploc-type) bag for this purpose before? This will answer your question as the bags are same except they are not as wide, about an inch & a half smaller in width, but are about an inch longer than the normal gallon storage variety sold at neighborhood stores.

Not sure, as I have no experience with shrink wrap. We used it for themed gift baskets, for the raffle at my church.

Unfortunately, these envelopes are NOT heat resistant. :-( I use Stamps.com for a lot of my postage needs, so will print the postage onto a label, then trim that label to fit on these envelopes. I'd only go thru the trouble to do this IF I wanted a "date" stamped on my postage, like for a mortgage payment, etc. Still, you'd be hard pressed to find a better deal for general usage. Hope this helps, Howard

Yes I believe they would. We are using them for documents, photos, instruction books, chorus books and many other items that are now toxic. The bags are nicely sturdy. The zip lock works and hold fine. Yes, I think they would be ideal for what you are asking.

I send mostly soft items but occasionally send something encased in cardboard. I think they are fine for paperback books but you might double bag hardbound books and they are so inexpensive you might not mind that cost. Hope this helps.

It's one layer stretch wrap as would be used for palletized freight. I don't think it would work with a heat gun.

I don't know - I've never tried to use regular ziplocks. I considered trying them out to see how it would go, but decided against it. The sealer uses heat to seal the bags, and the ones used for the Sealer System are much thicker material. *If* the sealer's heat is too much for the regular ziplocks then I'd have a mess on my hands cleaning up the melted plastic. Better to stick with the bags they recommend - which are far sturdier than any of the regular ziplocks, including the heavy freezer bags.

Kitchen trash bags should do it. I don't have the outer wrap any longer. I hope this helps. We get it at Cost Co. You might measure the box and ask them at the store which one would work best.

These are not self sealing. These bags require use of a bag sealer or tape.

No. They are stacked together in one big bag. Theres no need for individual wrapping, they dont make a mess. It would be easy to pull a few out, and put them in a zip lock.

We use them to ship light objects CD in cardboard cover etc. I would not use them for a hard back book. They would not hold up. The heaviest item we have shipped is a 6 disc plastic DVD size case and it had a manageable damage rate of 2 or 3 per 100, but was very light &lt;4oz. Avg hard back book is over a pound + .

Yes an impulse heat sealer or foodsaver like pump is necessary to seal these shut, although these bags are very thin and don't seal well and break easily after being frozen and the plastic stretching. Look into zippops they are the best alternative I found with good thick plastic and a ziplock like seal so you don't need a heat sealer even though you can use one anyway. This product here isn't good though

The bags are pretty big for putting into a box unless you folded them and worked them into the size you needed for the box as you were vacuuming out the air. There is nothing about the bag that would make them unsuitable for shipping.... if the vacuum seal gets broken, they will expand to fit the box, but I don't believe that they'd cause the box to explode!

they are shrink wrapped together in a mailing bag, but within the bag they are individually wrapped with tissues and sheets of foam. They are well protected.

You need food grade bags, I don't think these are right for cotton candy. They do melt when heated. Search for "food grade" bags and you should easily find a good match.

It should work fine for documents. Just fold over to fit better. If only a few documents I would probably line both sides with cardboard for some stiffness. I have been shipping books hard and soft cover without any problems. Hope this helps

I think you could use a heat sealer to seal the bags. I bought a couple when I purchased the bags but haven't used them yet. It just seems a lot easier and funner to tie them. Also the contents in the bag expand a lot after they are frozen so I would only fill them a little over half full and leave some room at the top for expansion.
