THE DETAILS

We've produced over 100 million of these bags and are super-confident in their ability to do the job of protecting your goods! We also guarantee their quality.

A flat bag (i.e. no gusset, but some stretch) with a matt finish and printed graphics as per the image gallery.

• PROTECTION
Waterproof, tough & durable (tear resistant with some stretch)

• LABELLING
Labels will stick to these bags* and the lighter colours can be written on with permanent marker.

• RE-USE
'Cut here to reuse' instructions are printed along the seal. Larger sizes have two seals to facilitate re-use.

• OPACITY
Our Black Dirt Bags are completely opaque, all other colours are slightly transparent.

• SIZES & SEALS
Seal with a fold-over flap and a peel-and-seal adhesive strip. Check the Sizing Guide as the bag thickness and number of seals vary by size.

• SHELF LIFE
Compostable packaging degrades over time, so we are only able to guarantee the performance and usability of these products for 6 months from date of purchase.

*We do extensive QA testing with our own labels and others, but can't guarantee that ALL labels will stick to these mailers.

• Made from completely biodegradable and compostable materials; corn starch, PLA (synthesised from corn) and PBAT (Polybutyrate Adipate Terephthalate).

• This combination of materials is non-toxic and contains no Phthalate or Bisphenol A (BPA).

• Certified free of GMO material.

• While these materials are biodegradable and compostable, they are not 100% renewable as the PBAT component is derived from petroleum-based materials. We are limited at the moment by the availability of suitable, sustainable raw materials that deliver the barrier and performance properties we need but are always testing resins made from an even greater amount of plant-based material – exciting times!

• CARBON NEUTRAL
We offset any carbon emission from this already low energy production process.

• Production uses approx. 30% renewable energy.

• Here for a good time, not a long time, these mailers will biodegrade in a home compost in 3-6 months and even quicker in a commercial composting facility.

• Safe for worms, worm farms and bokashi bins.

• Any remaining self-seal strips and labels (unless specified as compostable) should be removed before composting.

Seedling AS 4736 Industrially Compostable

We've been using BPCo's compostable satchels and labels for a few years now and the quality is so great! Such an easy company to work with for custom orders and we're so glad there is finally a better environmental alternative. Our customers love receiving their packages in BPCo satchels too. Keep up the fabulous work! xx

Thanks so much Kirsty, its such a pleasure to be able to make beautiful packaging for incredible brands like yours.

I absolutely LOVE these compost packs. Better Packaging truly makes you feel better, and they are just so beautiful! So light to touch and yet tough when filled with our products. I'm so happy we have made the switch. We use both the small and medium size and find they fit a lot more in than we expected!!

Really happy I made the switch from Aus Post plastic satchels to these biodegradable satchels. The quality is great and my customers even message me to say how happy they are I'm using such a great product. Totally worth the small extra cost, I feel good using them and my customers are happy too! Emily @mummycouture
