File 1: Simple packaging is not the only environmental countermeasure

Eco-conscious as they are, many Japanese people say simple packaging suffices for mid-year and year-end gifts. However, this does not necessarily mean that all packaging can be eliminated. For example, the plastic wrappers of perishable foods are a must, and cans and plastic bottles for beverages are a necessity. With respect to such wrappers and containers that cannot be eliminated, there are strong demands to manufacture them using minimum raw materials--and recyclable materials at that.

Do you know how the electronic and electric industries are working to conserve packaging resources? At Murata, we not only reuse outer boxes, but we also go a step further and substitute outer boxes with trays that are more convenient to use by customers, and otherwise promote ideas that are both resource-saving and convenient.
Electronic components are normally wrapped in tape. Currently, the most commonly used tape is the W8P2 tape, which is 8 mm wide and provides a 2 mm (or 4 mm) pitch. However, as can be seen in the photo below, the W8P2 tape tends toward excessive wrapping, so much so that it appears as though the paper tape is the item that is being sold and not the electronic components that are wrapped in it. Murata's solution to significantly reducing the amount of taping material waste　for extremely small 0402-size components is the W4P1 tape, which is 4 mm wide and has a 1 mm pitch (W4P1).



We also promote bulk packaging, which does not use tape to begin with, but instead uses a stick (a bulk pouch or bulk case) that automatically lines up loose components for mounting (see photo below), to further reduce the amount of packaging material waste.



These are just some of the ways in which Murata is an industry leader in the area of packaging.
