3 Sides Seal Bags Making

This video shows you how three-side sealed packaging bags are produced. Starting from the roll film, the machine will fold it first and then heat-seal the front and back sides. There are three heat-sealed edges, namely the left side, right side and bottom side. Since there are three heat-sealed edges in total, this packaging bag is called a three-side sealed bag, also called a flat bag.

Flat bags are the most common bag type and are often used to hold small and light items; due to their fast manufacturing speed and low manufacturing difficulty, the price of this type of packaging bag is the cheapest. You can also choose the custom flat pouches, you can add zippers, hanging holes, and tear notches to the flat bags so that they can be used repeatedly.
