Abstract
The objective of this thesis is to study and analyze the distribution and usage of reusable corrugated cardboard cases in the delivery of the product within the Frito-Lay system. The studies conducted looked at the various modes by which the cases fail and their effect on the fife of a case. Various case designs were tried in these studies to analyze the effect of the parameters like presence of string, in tackling the modes of failure and in improvement of the life of the case. The tests were conducted under normal operating conditions. The cases were introduced into the system in tune to the plant production. Cases that were returned were sorted and checked for damage. The damaged test cases that were deemed unsuitable for re-use were stored for examination. The examination of these cases revealed the type of failure and failure location. Additional data from the cases were also taken like, the number of trips, design code, etc. These data were entered into the computer and analyzed. The thesis contains analysis and results from three studies. Tests for the first study were run in Irving and Rosenberg plants, in Texas region. Additionally, to confirm the results from the Irving test, further runs were conducted in the Kilfingly plant, New York. The data and analysis of this study was the second part of this thesis. The third study is on the effect of variations of the width of the flap of a case to the load carrying capacity of the flaps when fan folded. Based on the results of these studies, recommendations have been made on the case design and handling procedures, which have a significant economic impact on the Frito-Lay system.
