Christmas XMAS Special Premium Mailing Bags. Strong Parcel Postage Plastic Post Poly Self Seal Recyclable, These bags are perfect for those Christmas mailings and make your festive period that extra bit special. Our range of recycled mailing bags are a professional choice, and are available in a range of sizes. They’re made from three layers of polythene film, which means they’re really strong – they’re both puncture and tear resistant. Those three layers are still incredibly lightweight though, meaning that they won’t add to your shipping costs unnecessarily. Although they are made from polythene, they are made from 100% recycled materials, and as long as the adhesive strip has been removed, they can be recycled again too. This makes them a great choice for businesses that want to highlight their eco-credentials. In addition to being a discreet packaging option that is also environmentally friendly, our recycled grey mailing bags are also incredibly practical. They are available in a range of sizes, and are a realistic price – and because they don’t take up huge amounts of space, you can easily invest in multiple sizes for your packing area.
