We offer electronic packaging boxes, which has open-close flaps, all of which are the same depth, and the outer flaps overlap by one inch or more. This type of design is useful when the box length is much greater than the width resulting in the large gap between the inner flaps. Commonly used in electronics and electrical industries for packaging large appliances, these electronic packaging boxes are made of best quality cardboard. This also increases its loading and holding capacity, which makes them a durable product.
