As a brand owner, packaging plays a vital role in your product’s success. Not only does it protect your product, but it also serves as a powerful branding tool that attracts customers and communicates your message. If you’re exploring flexible packaging options, you’ve likely come across 2-side seal pouches (2SS) and 3-side seal pouches (3SS). But what’s the difference, and which one is the best fit for your product? Let’s break it down.

A 2-side seal pouch is folded in half, then sealed on two sides and left open at the top or bottom for filling. Once filled, the final seal is made, creating a three-sided enclosure.
Compact Design: The folded structure eliminates the need for one additional seal.
Cost-Effective: Requires less material compared to other pouch designs, reducing packaging costs.
Customizable Sizes: Ideal for single-serving products or small quantities.
Single-use supplements like protein powders or vitamin sachets.
Trial-size cosmetic products such as creams or serums.
A 3-side seal pouch is sealed on three sides, leaving one side open for filling. This design allows for a flat, rectangular shape with a neat and uniform appearance.
Premium Look: The fully sealed edges create a clean, polished aesthetic.
Enhanced Durability: Seals on three sides provide added protection against leaks and contamination.
Flexible Filling Options: Can be filled manually or through automated processes.
High-end cosmetic products like face masks or sample kits.
Nutraceutical items such as herbal teas, gummies, or capsules.
When deciding between 2-side and 3-side seal pouches, consider the following factors:
Product Type:
For single-serving or cost-conscious items, 2-side seal pouches are a great option.
For premium products that demand a polished look, go with 3-side seal pouches.
Brand Aesthetic:
If your brand prioritizes elegance and sophistication, 3-side seal pouches align better with that image.

Four-side sealing and three-side sealing are two common ways of packaging goods. Four-side sealing means wrapping the goods with plastic film and sealing them on all four sides with heat. Three-side sealing means sealing on three sides and leaving one side open for loading the goods. You can see the difference from the photos.
As you can see, the 3-side sealing Sachet is of the same shape as a 4-side sealing sachet. But the front and back panels are actually regionally sealed and then folded at one side for product filling. Generally, the bottom or edge side of the bag is folded which allows the pouch to flex and have products adjust to the correct position of the pouch.
4 sided seal: Four-side sealing provides excellent sealing, protecting goods from pollution and damage. In addition, 4 side sealing pouch can provide a larger display area and a more beautiful presentation effect.
3 side seal: 3-side sealing pouch has lower costs, offers easier storage and handling. Also, without the need for any tools, just rip it open by the tear notch.
However, different goods have different packaging requirements:
Four-side sealing: Four-side sealing is great for products that need full protection, longer warranties, and brand displays, like high-quality electronics.
These products normally must be kept away from moisture, dust, and other things which could spoil their performance or quality.
Additionally, four-side sealing enhances the professional and high-quality appearance of products, boosting consumer trust in your company.
Three-side sealing: Three-side sealing is commonly used for products that are easy to clean and have short lifespans or low packaging requirements. These products include everyday items and food, such as ketchup, small snacks, facial masks.
These products usually do not need too many protection measures; most likely, they have an outer box to keep them safe. As long as they can keep their cleanliness and hygiene.
Also, this seal packaging method helps consumers easily open and use products, increasing their satisfaction and effectiveness.
Now, we will compare the size/capacity of packaging for four-side sealing and three-side sealing by using a table.
After compare the size and volume from these two tables, we are going to talk about the Benefits of them.
