Fast to build your packaging by shape
According to the shapes and sealing methods, the types of flexible packaging are often divided into eight styles, which are three side seal bag, back seal bag, stand up pouch(doypack), side gusset bag(quad seal bag), flat bottom bag, spout pouch, special-shaped bag, and roll film.
Packaging pouches or roll stock films are seen everywhere in our lives. These bag pouches and roll films are commonly used for packaging foods, snacks, pet food, beverages, daily chemicals, consumer products, and other items.
Three side seal bag
Three side seal bag is sealed on both sides and along the bottom, leaving the top open for filling. After filling, the top is usually heat-sealed or folded.
Back seal bag
Back seal bag is formed by folding a sheet of film and sealing the overlapping edges at the back (creating a fin or lap seal). The bottom side is also heat-sealed, leaving the top open for filling. After filling, the top is sealed.
Side gusset bag
Side gusset bag (also called a gusseted pouch) is a type of flexible packaging that features expandable folds (gussets) on the sides to allow the bag to hold more volume.
Stand up pouch
Stand-up pouch (also called a stand-up bag or doypack) is a type of flexible packaging with a flat bottom gusset that allows it to stand upright on shelves, much like a rigid container. These pouches are popular for their convenience, eye-catching design, and functionality.
Flat bottom bag
Flat bottom bag (also called a block bottom bag or automatic bottom bag) is a type of packaging that combines the convenience of a flexible pouch with the stability of a box-like base. Unlike standard flat pouches, it has a reinforced bottom that allows it to stand upright when filled, making it ideal for retail display and easy storage.
Special-shaped bag
Special-shaped bag (also called die-cut pouch or custom-shaped bag) is a type of flexible packaging that is designed in a unique, non-rectangular shape to enhance branding, functionality, or consumer appeal. Unlike standard pouches (like stand-up or flat-bottom bags), these bags are cut into custom silhouettes using die-cutting techniques, making them stand out on shelves.
Spout pouch
Spout pouch (also called a spout stand-up pouch or liquid pouch) is a type of flexible packaging featuring an integrated spout (usually plastic or screw-top) designed for easy pouring, dispensing, or resealing liquids, semi-liquids, or powders. It combines the convenience of a bottle with the lightweight, space-saving benefits of a pouch.
Roll stock film
Roll stock film refers to flexible packaging material supplied in continuous rolls (rather than pre-made bags or pouches). It’s the raw material used by manufacturers to create custom pouches, bags, or wraps on high-speed filling and packaging machines.
1. Roll Stock Film Production Process
Roll stock film is the base material used to make pouches. Its production involves:
Step 1: Printing
Flexographic/Gravure Printing: High-speed printing of designs.
Step 2: Lamination (If Needed)
Combines films with aluminum foil, paper, or additional plastic layers using adhesives or heat.
Enhances barriers (e.g., retort pouches for sterilized food).
Step 3: Slitting & Winding
Jumbo rolls are slit into narrower widths for pouch-making machines.Rolled onto cores for storage/shipping.
2. Pouch Manufacturing Process
Pouches are made from roll stock film using form-fill-seal (FFS) machines or pre-made pouch converters.
Step1: Printing (If Not Pre-Printed)
Digital/flexo or rotogravure printing for custom designs.
Step 2: Lamination (If Needed)
Combines films with aluminum foil, paper, or additional plastic layers using adhesives or heat.
Step 3: Form-Fill-Seal (FFS) Process (For In-Line Production)
Film Unrolling → Fed into machine.
Forming → Folded into a pouch shape (vertical/horizontal FFS).
Sealing → Side/bottom heat-sealed.
Filling → Product dispensed (liquids, powders, solids).
Sealing → Closed and cut into individual pouches.
