● Retort Pouches: Specifically designed to withstand high-temperature sterilization, allowing for long-term food preservation without refrigeration.
● Stick Packs: Slender, tube-shaped packs ideal for single servings of powders or granules, such as instant coffee or sugar.
● Roll Stock: Packaging material delivered in a roll for clients to use with their in-house automated packaging machinery.
The Manufacturing Process of Flexible Packaging
The production of flexible packaging is a process that blends art with precision engineering. It can be refined into three core stages, each critical to the final product's quality, functionality, and visual appeal.
Stage 1: Pre-press and Printing
This stage begins with package design, plate-making, and printing. Using advanced technology and strict color management, sophisticated designs are accurately printed onto the flexible material, laying a perfect foundation for subsequent steps.
Stage 2: Material Converting and Roll Preparation
After printing and lamination, the material enters the critical converting phase. This is where Dah Bah Machinery’s expertise ensures optimal roll quality for downstream efficiency. Our precision Slitting Machines cut master rolls to exact widths, while our Roll Rewinding & Inspecting Machines guarantee that each roll is perfectly tensioned, aligned, and defect-free. For applications requiring pre-cut materials, our Cutting/Sheeting Machines provide precise and consistent results, preparing the material perfectly for the final stage.
Stage 3: Pouch Forming and Finishing
In the final stage, the prepared roll is transformed into a finished product. This is the core function of Dah Bah’s versatile Bag Making Machines which form and seal the primary pouch.
Beyond basic forming, Dah Bah offers a complete suite of finishing solutions to add value and functionality. Our specialized equipment enhances the final package with:
● Spout Inserting & Sealing Machines for liquid and pourable products.
