Job Application

Our three-sided seal bag, also known as a sachet, is a versatile and effective packaging option designed to meet a variety of industrial requirements. The main difference between this type of bag and afour-sided seal bag is that the front and back panels are welded shut on three sides, while one side remains folded. This folded side is usually at the bottom, allowing the bag to expand slightly and letting items rest comfortably on the bottom.

The three-side seal bag’s flat, compact design makes it ideal for packaging a variety of goods, such as coffee, snacks, dairy products, and beverages. The three-side seal pouches from Unified Flex offer product protection, freshness, and convenient storage. This design is particularly beneficial when consistent packaging is desired. Often, a folding carton or box can hold several sachets, giving customers the convenience of purchasing multiple packs.
