In industry, polyethylene fleece (most famously represented by Tyvek) is processed, among other things, into protective suits that are used in sterile environments. Due to the high tensile strength and the water-resistance of the plastic, PE-fleece is also used as a cover material in outdoor areas, as well as for admittance bracelets or map material.
Of course, the advantages of the paper-like material also apply to zipped bags accentuated with colored zippers. They hold their contents simply and safely, are incredibly light and durable and keep their promise of protective storage even with one or more raindrops. This makes the bags versatile: use to store office supplies, pens, paper, make-up, toiletries, tickets, documents, and more. And because the material can be wonderfully painted, glued, and sewn, the white bags can be easily personalized depending on your ideas.
