Walking into the assembly workshop of the ply-pack packaging machine factory, three latest iterations of bag-feeding packaging machines are undergoing final debugging before leaving the factory. The robotic arm flexibly grabs the pre-prepared food packaging bags, and with the subtle sound of vacuum exhaust, boxes of Dongpo pork are automatically sealed on the assembly line. "This is the third-generation equipment we customized for customers in the Yangtze River Delta. Now it can process 2.5 tons of semi-finished dishes per day." Workshop director Yang Gong introduced to reporters while testing the equipment.
As the pre-prepared food market continues to heat up, the traditional manual bagging packaging method is facing severe challenges. In the production workshop of a well-known catering supply chain company in the southwest, the reporter saw that the upgraded bag-feeding packaging machine was operating efficiently. The fully automatic bagging system accurately grabs aluminum foil packaging bags of different specifications, from metering and filling to hot-melt sealing in one go. "In the past, manual bagging always had wrinkles at the bag mouth. Now the automatic deviation correction function of the equipment has increased the yield rate from 87% to more than 95%." The production manager of the company revealed.
At the packaging machinery industry seminar held recently, the intelligent production line upgrade solution shared by the ply-pack technical team attracted attention. Its independently developed visual positioning system has successfully overcome the problem of packaging special-shaped bags. The reporter saw at the scene that for the popular octagonal hot pot base packaging bags on the market, the bag-feeding packaging machine can accurately identify the direction of the bag mouth and complete the bagging with the adaptive clamp. "This system has broadened the adaptability of the packaging form by 40%, and now even the wolfberry in the soup bag can be completely preserved." R&D engineer Xiao Wang said during the on-site demonstration.
What is more noteworthy is the modular design concept launched by the ply-pack factory this year. The same bag-feeding packaging machine can process 200g of ready-to-eat crayfish and 5kg of frozen seasoned steak by replacing the mold components. The purchasing manager of a food company in Anhui Province calculated: "In the past, we needed to purchase three devices. Now the modular transformation cost saves 60% of the budget compared to buying a new machine, and the utilization rate of workshop space has also increased."
Facing the personalized needs of small and medium-sized enterprise customers, the factory's packaging machinery customization service is opening up new markets. A time-honored sauce product factory in Jiangsu has tasted the sweetness - their unique wide-mouth pottery jar packaging has been automatically packaged through a customized version of the bag-feeding packaging machine. Factory manager Ms. Li said with emotion: "Traditional manual wax sealing is prone to secondary pollution. Now the equipment can not only maintain the rustic appearance of the pottery jar, but also has a more stable sealing than manual operation."
In the quality inspection area, the technician showed the "smart brain" of the bag-feeding packaging machine to reporters. The electronic pressure sensor monitors the vacuum degree of each packaging bag in real time, and any air leakage defects will trigger the automatic sorting device. This system has helped many customers pass HACCP certification, and the orders for Japanese teriyaki chicken steaks of an export-oriented company have increased their overseas market share by 30%.
"In the next three months, we plan to launch a bag-feeding packaging machine that is suitable for biodegradable materials." The general manager of the ply-pack factory revealed in an interview. With the tightening of environmental protection policies, the popularity of degradable packaging bags has brought new challenges to equipment manufacturers. At present, the factory has completed the continuous packaging test of corn fiber packaging bags, and the sealing strength has reached the general industry standard.
When leaving the factory, the reporter noticed that the neatly stacked equipment in the logistics area was being loaded. From the mushroom processing plant on the Yunnan-Guizhou Plateau to the seafood workshop on the Jiaodong Peninsula, these bag-feeding packaging machines that are about to go to all parts of the country are witnessing the surging wave of China's food packaging intelligent transformation. Just like the eye-catching slogan on the wall of the workshop: "Let every packaging bag carry ingenuity", this company that has been deeply involved in the industry for 20 years is using technological innovation to tell the packaging story of Made in China.
