Side seal bag:
This type of packaging bag has three sealed sides (two sides and the bottom), with the opening typically at the top. It is one of the most common bag types, often used for packaging food, daily necessities, and other products.
Its structure is relatively simple, making it cost-effective for mass production.Since only the top is open, it has better sealing, providing good moisture and contamination protection.
Back seal bag:
The sealing is located at the back of the bag, typically a vertical seal on the back. The sides and bottom of the bag are usually open, and the design of the front and back seals may differ.
Back seal bags are often used for products that require displaying the bag’s front design or artwork, as there is no seal line on the front, allowing for clearer presentation.
They are ideal for products that need to be easily opened and resealed, such as tea, snacks, etc.
In summary, the 3-side seal bag seals three sides of the bag with a simple structure, while the back seal bag seals the back side and is suited for products that need to showcase the front design.
