Side Sealing Bag Manufacturing Process

Side sealing is a bag-making process where the film is sealed along the sides of the bag, rather than at the bottom. It’s widely used for flat bags, garment bags, newspaper bags, and packaging bags.
01

Film Feeding

Pre-printed or plain film (LDPE, HDPE, PP, biodegradable, etc.) is fed from a roll.
02

Folding (if needed)

For certain bag types, the film is folded into half before sealing.
03

Side Sealing

Heat-sealing bars seal the film vertically along both sides, forming the bag shape.
04

Cutting

A cutting knife or hot blade separates each bag.
05

Options (Depending on Machine)

● Gusseting (side folds for expanding capacity)
● Perforation (for tear-off convenience)
● Punching holes (handle, air vent, or hanger holes)
06

Key Advantages of the Process

● High speed production (often faster than bottom seal for thin films).
● Suitable for multiple materials, including biodegradable and compostable films.
● Precise sealing, especially important for lightweight packaging.
