These kraft mailers are an eye-catching eco-friendly alternative to plastic mailing bags. Made from FSC-mix paper (a mix of recycled and sustainably sourced paper) these bags are fully home recyclable, compostable and biodegradable. Each 90gsm bag is 1 ply. External dimensions are 40.5cm long by 32.5cm wide with a bottom gusset of 8cm. The bags have a 3cm lip with a handy peel and seal strip.  Please note - internal dimensions are approximately 2cm smaller due to the seal around the edge, and any contents that use the full 8cm gusset will further reduce the available internal width. Designed and manufactured in the UK.
