INTRODUCTION

For the average private label, contract, or name brand manufacturer, suntan/ sunscreen products usually represent between 16% and 35% of their production.

With so much production devoted to this category, it is especially important to be

aware of any processing techniques that would enable one to bring the production

from the initial preweigh to filling as quickly and as efficiently as possible.
