Bottom Sealing Bag Manufacturing Process

Bottom sealing is a bag-making process where the film is sealed across the bottom of the bag, rather than along the sides. This method is especially suitable for T-shirt bags, shopping bags, garbage bags, and industrial packaging bags.
01

Film Feeding

Film (LDPE, HDPE, recycled materials, biodegradable films, etc.) is fed from a roll into the machine.
02

Flattening & Positioning

The film is spread and aligned to ensure precise positioning.
03

Bottom Sealing

A heated sealing bar seals the film horizontally across the bottom, forming the bag’s base.
04

Cutting

After sealing, a cutting knife separates each bag.
