Four Side Seal Bag

A four-side seal bag is a type of packaging used to store and transport various products, such as snacks, powders, and liquids. It is made by sealing the bag on all four sides, creating a rectangular shape that is flat and easy to handle. The bag is typically made of a flexible material such as plastic or foil, and can feature a variety of closures, including zippers, tear notches, and resealable options. Four-side seal bags are popular in the food industry for their convenience and durability, as well as their ability to protect the contents from moisture, air, and potential contaminants.

Four side seal bags take up less space than other packaging options, making them ideal for small items or products that require efficient storage.

>What's the 4 side seal bag compare to 3 side seal bag?

The main difference between 4 side seal bags and 3 side seal bags is the number of sealed sides. 4 side seal bag is sealed on all four sides, while  3 side seal bag is sealed on three sides, leaving one side open for filling.

4 side seal bags offer a larger surface area for customization with branding, graphics, and other information. 3 side seal bags have a narrower surface area due to one open end, which limits  the amount of branding or printing that can be done.

4 side seal bags generally require more complicated packaging equipment to fill and seal due to the four sealed sides. In contrast, 3 side seal bags can be filled and sealed with simpler machinery.
