Three Color Non Woven Bag printing Machine

About Three Color Non Woven Bag printing Machine

Key Specifications of Non-Woven Bag Printing Machines:

1. Printing Technology:

   • Offset Printing: Known for high-quality, detailed prints with accurate color reproduction, suitable for large print runs. Many non-woven bag printing machines are modified offset presses.

   • Flexographic (Flexo) Printing: Ideal for high-volume orders, offering excellent speed and cost-effectiveness. Uses flexible relief plates.

   • Screen Printing: Provides vibrant colors and a unique textured finish, suitable for smaller runs and specialty designs. Involves pushing ink through a mesh screen.

   • Digital Printing: Uses computer-controlled equipment to print images directly onto bags, offering versatility for intricate designs and variable data printing.

   • Heat Transfer Printing: Involves transferring an image from a sheet to the bag using heat and pressure. Offers full-color printing and durability.

2. Number of Colors:

   • Single Color: For basic logos or text.

   • Two Color: Allows for more complex designs with two distinct colors.

   • Multi-color (e.g., 3-color, 4-color, up to 8 colors): For elaborate designs, gradients, and photographic quality prints.

3. Maximum and Minimum Bag/Sheet Size:

   • This specifies the dimensions of the non-woven bags or sheets the machine can accommodate. Common ranges vary widely, for example:

     • Max Bag Length: 200-800mm

     • Max Bag Width: 100-800mm

     • Max Printing Area: Varies based on the machine model, e.g., 345x450mm to 605x420mm.

     • Minimum Bag Size: Can be as small as 125x180mm.

4. Material Thickness Compatibility (GSM - grams per square meter):

   • Bag Thickness: Typically ranges from 30 GSM to 150 GSM or even up to 300 GSM, depending on the machine.

   • Paper Thickness (if applicable): Many non-woven bag printing machines can also print on paper, with a thickness range often from 30 GSM to 250-300 GSM.

5. Printing Speed (Impressions Per Hour - IPH or meters per minute):

   • Varies significantly based on automation level and printing technology.

   • For bags, speeds can range from 20-120 pcs/min (for bag making machines with printing) or 2000-3000 IPH for dedicated printing machines.

   • For paper (if dual-purpose), speeds can be much higher, e.g., 2000-8000 IPH.

6. Automation Grade:

   • Manual: Requires significant operator intervention.

   • Semi-Automatic: Some processes are automated, while others require manual feeding or handling.

   • Automatic: Features like automatic feeding, printing registration, and drying systems for high efficiency and reduced labor.

7. Power Requirements:

   • Voltage: Often 220V/50Hz or 380V (three-phase).

   • Power Consumption (kW or HP): Varies from 1.1 kW to 18 kW or more, depending on the machine's size and capabilities.

8. Machine Dimensions and Weight:

   • Important for planning factory space and installation.

   • Weight can range from a few hundred kilograms (e.g., 150 kg for semi-automatic) to several tons (e.g., 2000 kg - 4000 kg for fully automatic).

9. Ink System:

   • Ink Rollers: Number of ink rollers (e.g., 10, 14, 16) and form rollers (e.g., 2, 3) for even ink distribution.

   • Water Rollers: Number of water rollers (e.g., 4, 5) for dampening (especially in offset printing).

   • Ink Type: Water-based inks are commonly used for non-woven bags due to environmental considerations. UV inks may be used for digital printing.

10. Additional Features:

    • Automatic Feeding System: Ensures continuous flow of bags.

    • Automatic Printing Registration: Guarantees precise alignment of colors.

    • Automatic Drying System: Prevents smudging (e.g., exhaust fans, heating systems).

    • Pneumatic Impression: Uses air pressure for consistent printing.

    • Centralized Oil Lubrication System: For smooth operation and reduced maintenance.

    • Pre-set Copy Counter: For production tracking.

    • Double Sheet Detector: Prevents machine damage and material waste.

    • Anti-static Charger: To remove static from the material.

    • Touch Screen Control Panel: For user-friendly operation.

    • Safety Features: Emergency stop buttons, safety guards.

    • Skip Feed Function: To control ink density.

    • 2-in-1 Capability: Some machines can print on both non-woven bags and paper sheets.
