Grey Mailers
Polythene plastic envelopes with tamper evident seals, a popular economical packaging option for postal orientated services.
Popular grey polythene mailing envelopes are often referred to as grey mailers or grey postal pouches. They incorporate a strong tamper evident self-sealing strip and are constructed from a co-extruded High Density Polyethylene (HDPE) film; this means they are produced from three layers of film which although not visible to the eye, creates a very strong product which offers protection against moisture and weather conditions, enables them to be highly competitively priced and they come in a diverse range of practical sizes.
