how to print on non woven shopping bag?

non woven shopping bag printing machine

A 1-color screen printing machine designed for non-woven shopping bags and paper bags with manual feeding, automatic printing, and automatic unloading is a great solution for efficient, high-quality printing of custom designs on these types of bags. This type of machine is commonly used in medium to high-volume production, offering a balance of manual input and automatic operations, which helps improve production speed while maintaining flexibility for custom or smaller runs.

Key Features of the 1-Color Screen Printing Machine

Manual Feeding:

• Operators manually place the bags on the belt.
• This provides flexibility in handling different sizes and types of bags.
• Ideal for small to medium batches or when high customization is needed.
• Vacuum suck the product during printing.

Automatic Printing:

• The machine is equipped with an automatic screen printing mechanism that accurately transfers the design onto the bags.
• The screen mesh holds the design, and ink is pushed through the mesh using a squeegee, transferring the image onto the bag.
• Automatic printing ensures consistent quality and faster print speeds compared to fully manual operations.

Automatic Unloading:

• After printing, the machine automatically removes the printed bags from the printing area.
• This increases efficiency and helps keep the production line moving without the need for manual intervention in unloading.
• The bags are often collected onto a conveyor system or stacked for easy access and packaging.

1-Color Printing:

• The machine is designed to print a single color in one pass. This is ideal for simple logos, text, or designs.
• Typically used for one-color branding, but you can always re-run the bags with additional colors if needed (though this will require additional setup).

Key Components of the Machine:

1. Printing Frame and Screen:
   • The screen is where your design is transferred. It’s made of mesh material and is stretched over a frame.
   • The frame holds the screen in place during printing and is often adjustable to accommodate different bag sizes.
2. Squeegee and Flood Bar:
   • The squeegee is a rubber blade that pushes ink through the screen onto the bag, ensuring the design is printed clearly and evenly.
   • The flood bar helps distribute ink evenly across the screen before the squeegee moves to print.
3. Ink Tray/Ink Cup:
   • The ink tray holds the printing ink, which is used to print the design onto the surface of the bags.
   • Some machines have automatic ink delivery systems to ensure consistent flow of ink during the printing process.
4. Conveyor or Unloading System:
   • After printing, the bags are either placed on a conveyor belt for further processing or automatically ejected into a stacker or unloading station.
   • The automatic unloading feature helps reduce downtime and labor requirements.
5. Control Panel:
   • The user interface that allows the operator to set printing parameters, such as printing speed, pressure, and timing.
   • It also helps in adjusting settings for bag size, screen tension, and ink type.
6. Bag Holder/Feeding Platform:
   • A platform or fixture holds the bag in place while it is being printed. For non-woven and paper bags, these fixtures can often be adjusted to accommodate different sizes and bag types.

Advantages of a 1-Color Screen Printing Machine for Bags:

1. Speed and Efficiency:
   • Automated features such as printing and unloading significantly increase throughput compared to fully manual systems, making it suitable for medium-scale production runs.
2. Cost-Effective:
   • A single-color machine is generally more affordable than multi-color screen printing machines, and it is highly effective for simple designs (e.g., logos, text).
3. High-Quality Prints:
   • Screen printing offers high opacity, vibrant colors, and durability, ensuring that the prints on non-woven or paper bags last a long time, even under rough handling.
4. Customizability:
   • The machine can handle various bag sizes and materials, making it suitable for different types of non-woven or paper bags, including eco-friendly and promotional items.
5. Easy Operation:
   • The semi-automatic design (manual feeding with automatic printing and unloading) allows operators to maintain control while benefiting from increased efficiency.

Applications:

• Retail and Promotional Bags: Printing company logos, product images, or marketing messages on non-woven shopping bags and paper bags.
• Event and Packaging Bags: Custom printing for corporate events, trade shows, and retail packaging.
• Eco-Friendly Branding: Non-woven bags, often used as eco-friendly alternatives to plastic bags, can be printed with sustainable messages or logos.

Considerations When Choosing a Machine:

1. Bag Size and Material:
   • Make sure the machine is capable of handling the sizes and thicknesses of non-woven and paper bags you plan to print. Adjustability in the print bed size is essential for versatility.
2. Ink Type:
   • The machine should be compatible with inks designed for non-woven materials and paper. Water-based or eco-friendly inks are often used for environmental sustainability and safety, especially with paper and fabric-like materials.
3. Printing Speed:
   • Consider the speed of the printing cycle. Higher printing speeds are important for meeting deadlines or large orders, but make sure that print quality is not sacrificed for speed.
4. Maintenance and Support:
   • Check the ease of maintenance and whether spare parts or technical support are readily available. Good service and maintenance can help ensure long machine life.
5. Automation Level:
   • Some machines may have more advanced automation (e.g., automatic bag feeding) which can further reduce manual labor but may also increase cost. Balance automation needs with your budget.

Conclusion:

A 1-color screen printing machine for non-woven shopping bags and paper bags, with manual feeding, automatic printing, and automatic unloading, provides an efficient, cost-effective solution for businesses looking to print simple designs on a variety of bags. The semi-automatic nature of the machine improves production speed while still offering flexibility for custom orders, making it a great choice for companies with mid-range production needs.
