These non-padded mailers ensure that your contents arrive in perfect condition by utilising a unique co-extruded manufacturing process. This produces tougher, lighter mailers with exceptional features including a smooth, inner layer allowing for quick, easy product insertion. A self-seal perforated strip facilitates easy opening while strong, high strength welded seams resist bursting and allow for overstuffing. Its outstanding water resistance protects contents from the elements and the improved tamper-resistant, self-seal closure saves labour, keeps contents secure and provides complete opacity to assure security of contents.
