Excerpts from the report: This report describes the development and evaluation of improved packages, packing materials, and master containers for fresh peaches. The study on which this report is based is part of a broad program of marketing research to hold down marketing costs and to deliver better farm products to the consumers. The purpose of this study was to maximize the sale of peaches and returns to the grower by shipping the fruit in a "family" of different containers. Package differentiation permits the marketing of peaches in containers most suitable for particular sizes or qualities, and most profitable in particular segments of the consuming market. The prices received for any one type of package are not as important as getting the highest average price for the whole crop of peaches.
