Which type of package is it for shipping?

Hi!

I am starting to sell infant bodysuits and toddler t shirts in my shop. I purchased Tear-Proof Polyolefin Mailing Envelopes to ship them in, so they are really like thick plastic bags.

My question is - when I go to purchase an etsy shipping label, do I say it's a thick package/envelope, OR do I say it's an irregularly shaped package?


Here are the descriptions for the mailing labels:
Package Types

Package is any parcel with a combined length and girth no greater than 108".

Thick Envelope is any rectangular envelope thicker than 3/4".

Irregular Package is all non-rectangular parcels with a combined length and girth no greater than 108" and rolls or tubes up to 26" long.

I'd appreciate any help! Thanks!!!

Package/envelope

That's how I mail all my stuff is in the poly envelope.

If you're shipping through Etsy it would probably qualify as a package/thick envelope.

if i’m shipping through etsy and im using a small box that measures in at 6x6x6 , could i consider it to a be a package/thick envelope? 

all the options for a small box with a flat rate are $10 and up which seems unfair.
