Pre-opened Bag Machine Variants for Different Bag Designs
The SNDA Pre-opened Bag Making Machine now includes multiple configurations to produce bags with different opening features. Each variant uses one or two sealing lines and two perforating lines, with the perforation location and design adjusted to match the bag's intended use.
Single Sealing Line with Side Easy Open Perforation
This machine configuration has one sealing line and two perforating lines. One perforation is on the bag bottom for standard pre-opening during production. The second perforation is on the side of the bag, designed to allow easy opening after the item is packed inside.
Single Sealing Line with Top Easy Open Perforation
This variant includes one sealing line and two perforating lines. One perforation is on the bag bottom for inline pre-opening. The second is on the top edge, forming a pre-cut line for easy opening after packing. The top perforation can be adjusted to full width or 60% to 80% open by changing the blade width.
Dual Sealing Lines for Hanging Features
This configuration uses two sealing lines to enable additional bag features such as mexico-hat, euro, banana, or handle punching. These features allow the bag to be hung after packing, which is useful for retail or display applications.
Dual Sealing Lines with Top Easy Open Perforation
This machine has two sealing lines and two perforating lines, with one perforation on the bottom for pre-opening and another on the top for easy opening after packing. The top perforation can be customized in width using different blade options.
How the Machine Processes Poly Film and Kraft Paper
The machine processes rolls of poly film or kraft paper, forming the bag structure through sealing and perforation. The process runs continuously, with the machine stopping automatically when the set roll length is reached.
Applications for Pre-opened Bags on a Roll
These bags are used in e-commerce fulfilment, 3PL operations, and automated bagging lines. The pre-opened design allows fast, consistent feeding into autobaggers, reducing manual handling and increasing throughput.
