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 & puncture resistant ensuring your goods are protected from the elements, whilst the grey outer & black inner ensures goods are concealed for peace of mind during transit. Featuring a peel & seal adhesive strip for a strong & 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.
