250g Postal Box Bottom Bags

Full-Size Bags. Letterbox Delivery.

Your bestselling 250g bags, sized to ship smarter. These Postal Box Bottom Bags are built to fit A4 mailers—so your customers get letterbox delivery and you avoid the “sorry we missed you” card. Full retail size, postal-friendly dimensions.

Most roasters default to standard 250g box bottoms, then realise they need oversized boxes to ship them. This bag fixes that. Same premium format, same shelf presence, but designed around Royal Mail and courier-friendly sizing.

Perfect for:

• Subscription services – Full 250g portions that arrive through the letterbox
• Online retail – Reduce shipping costs and failed deliveries
• Gift orders – Fits alongside cards or extras in a single mailer
• Wholesale samples – Professional presentation for trade customers

Why roasters choose these bags:

• Recyclable materials – EVOH-PE / White PE, kerbside recyclable
• Degassing valve – Releases CO2, keeps oxygen out, preserves freshness
• Standard zipper – Customers reseal after opening
• Smooth matte finish – Premium feel in black or white
• Stable box bottom – Stands upright in the box and on the shelf
