    • Wipers in roll form or separate sheets are stored in a plastic bag. A reclosable outlet is provided for the bag. In use with roll-form wipers, a restricted outlet is provided so as to provide resistance to the withdrawal of a strip of wipers from the bag, and allow them to be torn off along perforation lines delineating the wipers from one another. Preferably, the wiper material has a cleaning liquid absorbed in it. The bag material is a laminate comprising aluminum foil sandwiched between layers of polyester with an inner layer of polyethylene. This material is highly resistant to attack by aggressive solvents. In use with separate wipers, the bag has a slide-fastener closure which gives a wide outlet opening and adhesive-free closing.
