Polycarbonate is a synthetic material widely used in consumer products because of its excellent durability, heat and chemical resistance, and affordability. You can get luggage that's finished with a layer of polycarbonate, which will help the case withstand the inevitable wear and tear that comes with travel. There are plenty of ways you can prevent scratches and damage to polycarbonate luggage to extend its life and keep it looking its best.
Apply a lacquer or other protective coating agent that's safe for use with polycarbonate plastics. This will add a layer of resistance that will make it harder for scratches to penetrate the luggage surface.
Avoid exposing the polycarbonate luggage to excess amounts of sunlight, rain, heat and cold. These will all weaken the polyester and carbonic acid that make up the luggage surface. With consistent exposure to these elements over time, the luggage will become more prone to scratches.
Carry the luggage correctly at all times. Always use handles to carry lighter polycarbonate suitcases. If the luggage has wheels, use them instead of dragging the case across the floor or ground.
Take care when placing polycarbonate luggage on airport scales or conveyor belts, ensuring that you lay them down gently and avoid dropping them.
Store polycarbonate luggage properly when it's not in use. Keep it in a dedicated space where it won't come into contact with other items that could rub against it or scratch it. A cool, dry, dark place such as a closet works best, as it will also minimize the luggage's exposure to dust.
