What Is a Three Side Seal Bag?

Three Side Seal Bags

Structure and Design

A three side seal bag is a flat pouch sealed on three edges, leaving one side open for easy filling. You will often hear these called flat or pillow pouches in the packaging industry. After you fill the pouch, you seal the open side, which keeps out air and moisture. This design helps protect your products and keeps them fresh.

When you look at BN PACK’s Three Side Sealed Pouch, you see a great example of this structure. The flat shape makes it easy to stack, store, and display. You can use these pouches for both manual and automated packaging. Machines like Vertical Form-Fill-Seal (VFFS) or Horizontal Form-Fill-Seal (HFFS) systems handle the process quickly and efficiently. Manufacturers use roll film, fold it, cut it to size, fill it, and then seal three sides. This method supports high-quality production and allows for custom printing.

You can choose from a variety of materials to match your needs. Here are some common options:

  • High-quality laminated materials such as nylon, aluminum foil, and PET for strength and flexibility

  • Excellent barrier protection against moisture, oxygen, light, and bacteria
