Shanghai, China — Depai Machinery, a specialist in automatic packaging equipment for paper bag manufacturers, will exhibit at All in Print China 2026, held October 12–16 at the Shanghai New International Expo Centre (SNIEC). The company invites paper bag producers, printing and converting plants to visit Booth N3A131, where its automatic bag-in-bag packaging line for finished paper bags will be demonstrated on site.
Producing food paper bags and shopping bags is only half the job. Before an order can reach a bakery, supermarket or retail chain, every batch of finished bags must be collected and packed into outer bags — ready for clean, countable, on-time delivery. In most converting plants this final step is still done by hand: operators open each outer bag, count and insert the finished bags one stack at a time.
It is slow. It is labor-intensive. And when a plant is running large orders for food-service customers, manual bagging becomes the bottleneck that delays shipment and eats into margin.
That is the gap Gaoxiang's equipment is built to close. The showcased line is an automatic bag-in-bag packaging solution: outer bags are fed and opened automatically, finished paper bags are inserted, and packaged bundles are delivered in one continuous flow — removing the manual bagging steps that slow down finishing departments.
Designed with a clean, modular, linear layout and a swivel-arm HMI touchscreen, the line keeps size changeover straightforward, so a plant can move between food paper bag orders and shopping bag orders without long downtime. The result: consistent, presentable packaging that keeps food-grade bags clean through to the customer's doorstep.
For Depai, the story is not about a single model. It is about helping paper bag manufacturers automate their finishing and packing stage — covering bag feeding, insertion, bundling options and after-sales support. Every line is configurable to the customer's product mix, order sizes and packaging formats.
Headquartered in Wenzhou, Zhejiang — one of China's most established packaging machinery clusters — Depai Machinery has long served international buyers with reliable equipment, responsive spare-parts service and application know-how accumulated across real production environments.
