Certified home compostable courier satchels to the Australasian Standard, AS5810. Available in packs of 100. Fully biodegradable. Matt black finish with white graphics. Flat, no gusset, but some stretch with a 30mm flap (not included in the bag sizes) with self-seal strip. Behaves just like a plastic satchel except when left in nature! In a home compost, will biodegrade in 3-6 months. Labels will stick to me no problem, and I’m waterproof and strong.
