Some edible oils are hydrogenated. This process is known as "hardening" of the oil.
Hardened oils are used to make margarine.
Hardening improves the performance and the sale of margarine at ambient temperature.
This could explain why the fried potato chip has such a high fat content.
Also the chip may not be made up of starch and water alone
