-Cellophane: breathable and biodegradable so it is useful for food packaging, but not recommended for long term packaging. More expensive.
-Polypropylene: non breathable, clearer, keep food fresher longer, cheaper, not biodegradable.
I’ve used both types of bags before. And I love them both. I like the crispness of cellophane bags but I love the price and durability of poly bags. It really just depends on which type of plastic you prefer.
They are not self sealing. But they heat seal perfectly for me on setting 3 on my impulse heat sealer!
If you are purchasing bags, stencils, and scribes, then they will ship next day. But if you order bags with cutters, your processing time will be whatever our current processing time is. So if processing is 1 to 2 weeks, you won’t receive your bags until your cutters are printed and processed. If you would like your cutters and bags to ship separately so you can receive your bags sooner, you must place two separate orders. Thanks!
