Pre-made Bag Packers (Euro-style): These machines use pre-formed plastic bags. The stack is inserted into the bag, often with an "insertion angle," and then sealed. They are known for producing a high-quality finished look.
Pillow Pack / Flow Wrap Machines: This type uses a roll of film to form a bag around the product. The film is wrapped around the diaper stack, and the ends are sealed, creating a distinctive "pillow" shape. This method is common for single-piece trial packs or smaller packages.
Fully Integrated Stacking & Bagging Lines: The most advanced systems combine the stacking and bagging processes into a single, continuous machine. This "two-in-one" design saves floor space and is designed for maximum efficiency at high speeds.
