Frequently Asked Questions

AI
Many grey mailing bags are made from recyclable plastics, but you must check the specific product description. Some contain mixed materials that make recycling difficult. Look for bags explicitly marked as 100% recyclable or made from post-consumer recycled content to ensure environmental responsibility.
Self-seal envelopes feature an adhesive strip covered by a peel-off liner, offering quick and easy closure without water or heat. Gummed envelopes require moistening the adhesive, which can create a stronger, more tamper-evident seal but takes longer to prepare. Self-seal is generally preferred for high-volume shipping.
Measure your item’s length, width, and thickness, then add 1-2cm to each dimension for padding and ease of packing. Avoid oversized bags as they increase postage costs and reduce protection. For flat items like documents or cards, standard A4 or A5 sizes are usually sufficient.
