In the retail, food, and takeaway sectors, square bottom paper bags are favored for their large capacity and stable stacking. The RZFD-250 Square Bottom Paper Bag Machine, with its optimized design for packaging, has become the core equipment in these production scenarios.
This machine breaks through the size limitations of traditional models, capable of steadily producing square bottom paper bags ranging from 240–570mm in length. Each bag offers high load-bearing capacity, fully meeting the daily packaging needs of retail and takeaway businesses. Its high-speed production technology significantly improves the efficiency of bottom folding and gluing, achieving a maximum output of 220 bags per minute and a daily capacity of 300,000 bags—easily handling bulk orders.
To address the challenges of processing thick paper, raw material loading is supported by a hydraulic lifting system, while unwinding is managed by fully automatic constant tension control. It can handle paper weights ranging from 50–150g/m², with a servo-driven precision cutting system that ensures excellent top-edge flatness and minimal deviation. Additionally, the Italian SELECTRA web guiding system guarantees stable high-speed operation of paper rolls.
In terms of user-friendliness, the Schneider touchscreen offers multilingual switching and allows operators to preset multiple commonly used specifications. During product changeovers, there is no need for repeated adjustments. The modular design of the machine ensures that key components can be quickly disassembled and replaced, greatly reducing maintenance costs. Choosing the RZFD-250 means square bottom paper bag production that is both efficient and stable, delivering a reliable solution for eco-friendly packaging.
