I'm looking to purchase a fully automatic paper bag manufacturing machine specifically designed for producing square-bottom bags without handles. The intended application is for food and bakery products, so it's crucial that the machine is compliant with food safety standards. Additionally, I'm interested in a model that can efficiently produce various sizes to accommodate different customer needs. It's essential for the equipment to include printing capabilities for branding purposes. Please provide me with detailed specifications of the available models, including their production speed, size variations, and any optional features. Also, include pricing information so I can assess the investment required. Looking forward to your detailed response!
