Our 850mm x 1050mm grey recycled poly mailers are the ideal postal packaging solution for larger, non-fragile items. Constructed from 60mu polythene, these mailing bags are tear and puncture resistant ensuring your goods are protected from the elements, whilst the grey outer and black inner ensures goods are concealed for peace of mind during transit. Featuring a peel and seal adhesive strip for a strong and secure closure, our grey poly mailers are stocked in packs of 150. Made from recycled materials, these mailing bags are recyclable too, making them a great packaging choice to start reducing your impact on the environment.
