LDPE blown film extruder with rotogravure inline printer is a specialized piece of equipment used for producing high-quality zipper bags. This machine combines two essential processes in zipper bag production, the blown film extrusion process, and the printing process. With this equipment, manufacturers can produce zipper bags with precision, accuracy, and efficiency.

Benefits of LDPE Blown Film Extruder with Rotogravure Inline Printer

The benefits of using LDPE blown film extruder with rotogravure inline printer include:

  • High-quality film: The machine produces film with consistent thickness and excellent print registration, resulting in high-quality zipper bags.
  • Customization: The machine can print custom designs and logos, allowing manufacturers to offer unique and branded products.
  • Increased efficiency: The machine combines two processes, saving time and reducing waste in the production process.
  • Cost-effectiveness: The machine produces high-quality film at a lower cost than other production methods, reducing production costs and increasing profit margins.

The Process of LDPE Zipper Bag Production

LDPE Zipper bag production involves several steps, including:

  1. Material preparation: The raw materials, including LDPE pellets, colorants, and other additives, are mixed and prepared for the extrusion process.
  2. Blown film extrusion The LDPE pellets are melted and extruded through a circular die to create a continuous tube of plastic.
  3. Printing: The film is printed with a design using rotogravure printing technology.
  4. Lamination: The film is laminated to a second layer of film or paper to add strength and durability to the bag.
  5. Bag making: The laminated film is cut and sealed to create the final product, the zipper bag.
