Standup pouches are presently one of the highest selling consumer packaging products. Thanks to their convenience of storage space, product freshness seal lock, and environment friendly processes, standup pouches are considered ideal for liquid packaging, cereal packaging and even tea packaging.
Read on to find out how printing cylinders used for the production of these pouches are manufactured.
- First, good quality blank sheets of steel are taken and molded into long cylindrical shapes.
- Next, these rolled cylindrical hollows are joined with a core of steel.
- After having inserted a steel core to the rolled cylindrical steel sheets, these cylinders are engraved with their unique identification number.
- They then undergo the process of electroplating by covering them in a layer of copper.
- The copper layered cylinders are polished and also buffered for additional protection against rusting.
- Next step is the engraving of cylinders to etch the image or artwork onto their surface.
- A layer of copper is added to the cylinders to ensure extra strength and protection. They are then reviewed for any faults.
- Finally, they are covered and transported to the factories for the production of standup pouches.
With such careful processes, printing on pouches is durable and safe.
