Integrated Application of Thermal Transfer Overprinter and Automatic Bag Feeder

A thermal transfer overprinter (TTO printer) is an important industrial marking and coding machine, commonly integrated into various packaging equipment on food, daily chemical and other production lines. Beyond its typical integration with pillow and vertical packaging machines, a TTO printer is often paired with an automatic bag feeder. 

What is an Automatic Bag Feeder?

An automatic bag feeder, also known as an automatic pouch feeder or automatic pouch feeding machine, is a mechanical device used to separate stacked or aligned packaging bags one by one and feed them into subsequent processing equipment. 

These feeders employ various techniques like vacuum suction, friction separation, or mechanical separation to isolate each bag. The separated pouches are then transported to the next processing stage, which might involve printing, coding, or labeling, using a conveyor belt or other transfer mechanisms.

Integration of Automatic Bag Feeders and Thermal Transfer Overprinter

TTO printers, ideal for batch coding on flexible packaging, often find their perfect partner in automatic bag feeders when marking information on pre-made bags like food pouches or shampoo refills.

Common applications include:

● Food Industry: Snack bags, frozen food bags, seasoning packets, etc.

● Personal Care Industry: Shampoo refill packs, detergent bags, face mask pouches, and more.

● Medical Industry: Pharmaceutical packaging bags, medical device packaging bags, etc.

In these industries, products are usually packaged in plastic bags or multi-layer composite film bags. The automatic pouch feeding machine separates these bags one by one and feeds them into the TTO printer for batch coding. The coding content includes production dates, expiration dates, ingredient lists, and more.

How to Choose a Suitable Thermal Transfer Overprinter?

When selecting a suitable TTO printer, consider the following aspects:

1. Printing Requirements

Choose the type, speed, resolution, and print width of the thermal transfer overprinter based on the specific needs of your production line.

On high-speed conveyor production lines, continuous thermal transfer overprinters are typically selected. If there are pauses during the coding process, choose an intermittent TTO printer and install a synchronizer.

The HPRT FC53 series covers both continuous and intermittent printers, offering pneumatic and electric coding with 300dpi high resolution. The print adheres strongly and is resistant to water, oil, high temperatures, and scratching. 

The speed of FC53 batch coders is adjustable, and it comes with a stand, suitable for integration into packaging lines for food, pharmaceuticals, and other products.

2. Compatibility

It's necessary to check that the thermal transfer overprinter is compatible with existing automatic bag feeders and production line equipment to avoid production interruptions due to incompatibility.

3. Ease of Operation

Opt for TTO printers equipped with user-friendly interfaces and simplified maintenance procedures. This reduces operator training costs and improves overall production efficiency.

4. After-Sales Service

Choose brands that offer comprehensive after-sales service and technical support to ensure timely repairs and replacements in case of equipment failure.
