In the beverage, food, daily chemical and other industries, stand-up pouches have become the mainstream choice for liquid and paste product packaging due to their portability, freshness preservation and high appearance. However, enterprises often face multiple challenges in the stand-up pouch packaging link: products with different viscosities (such as thin soymilk and thick sauce) require equipment replacement, resulting in high investment costs; manual pouch hanging and cap arranging are inefficient, only hundreds of pouches can be completed per hour, making it difficult to deliver bulk orders; large filling volume errors and unstable capping easily lead to liquid leakage and deterioration, with high customer complaint rates.<\/span><\/span><\/div>\n
\u200b\"\"<\/span><\/div>\n
The LY-ZLD series stand-up pouch filling and capping machine developed by Longying itself focuses on “multi-specification adaptation, full-process automation, and high-precision stability”, perfectly solving the above pain points. It can cover the packaging of products in multiple fields such as beverages, food, and daily chemicals, and has become a “core tool” for enterprises to reduce costs and improve efficiency.<\/span><\/span>\u200b<\/span><\/div>\n
1. Multi-Specification Filling Pumps for All Liquid and Paste Products<\/span><\/span>\u200b<\/span><\/div>\n
One of the core advantages of the LY-ZLD series stand-up pouch filling and capping machine is that it is equipped with <\/span><\/span>different specifications of filling pumps<\/span><\/span>, which can be flexibly switched according to product viscosity without replacing the entire equipment, greatly reducing the investment cost of enterprises.<\/span><\/span>\u200b<\/span><\/div>\n
For <\/span><\/span>low-viscosity products<\/span><\/span> (such as soymilk, soybean milk, purified water, iced water, beer), the equipment adopts a special filling pump for low viscosity, combined with a precise flow control system, which has fast filling speed without splashing. It can stably output 800-1200 pouches per hour, with an error controlled within \u00b11ml, avoiding raw material waste; for <\/span><\/span>medium-viscosity products<\/span><\/span> (such as fruit pulp, fruit juice, edible oil), a medium-viscosity adaptive pump is selected, and the anti-hanging design reduces product residue to ensure uniform filling volume of each pouch; for <\/span><\/span>high-viscosity products<\/span><\/span> (such as ice cream, sauce, condiments, detergent chemical liquids), a special pump for high viscosity is equipped, combined with strong injection filling technology, which can easily handle thick textures, avoid blockage, and support nitrogen filling function to extend the product shelf life (for example, the shelf life of sauce can be extended from 15 days to 30 days).<\/span><\/span>\u200b<\/span><\/div>\n
Whether it is a beverage as thin as water or a sauce as thick as sesame paste, the LY-ZLD series equipment can “handle it with one machine”, eliminating the need for enterprises to purchase separate packaging equipment for different types of products, and reducing equipment investment costs by more than 60%.<\/span><\/span>\u200b<\/span><\/div>\n
2. Full-Process Automated Operation, Labor Cost Reduced by 70%<\/span><\/span>\u200b<\/span><\/div>\n
Traditional stand-up pouch packaging requires 6-8 people to cooperate: 2 people for pouch hanging, 2 people for filling control, 2 people for cap arranging and capping, 1 person for capping, and 1 person for quality inspection. The process is cumbersome and inefficient. The LY-ZLD series equipment realizes full-process automation “from pouch hanging to finished product discharge”, <\/span><\/span>only 1 person is needed to monitor one machine<\/span><\/span>, completely getting rid of manual dependence.<\/span><\/span>\u200b<\/span><\/div>\n
1. Automatic Pouch Hanging + No-Pouch Detection, Avoiding Idle Operation<\/span><\/span>\u200b<\/span><\/div>\n
The equipment is equipped with an <\/span><\/span>air cylinder automatic pouch hanging system<\/span><\/span>, which can automatically grab the stand-up pouch and accurately position it without manual placement; at the same time, it is equipped with a no-pouch detection sensor. If there is an empty pouch or missing pouch, the equipment will stop and alarm immediately, avoiding idle operation and ensuring production continuity.<\/span><\/span>\u200b<\/span><\/div>\n
2. Strong Injection Filling + Nitrogen Filling + Pouch Cleaning and Drying, Guaranteeing Both Quality and Appearance<\/span><\/span>\u200b<\/span><\/div>\n
The filling link adopts strong injection filling technology. For oxidizable products (such as fruit juice and sauce), nitrogen can be filled simultaneously to isolate air and delay deterioration; after filling, the equipment automatically starts the <\/span><\/span>pouch cleaning and drying function<\/span><\/span> to remove residual products (such as sauce and fruit juice) at the pouch mouth, avoiding pollution or poor sealing during subsequent capping, and keeping the pouch body clean to improve the product appearance and help terminal sales.<\/span><\/span>\u200b<\/span><\/div>\n
3. Automatic Cap Arranging + Capping + No-Cap Detection, Doubling Capping Efficiency<\/span><\/span>\u200b<\/span><\/div>\n
The equipment is equipped with an <\/span><\/span>automatic cap arranging system with a cap arranging tray<\/span><\/span>, which can quickly arrange messy caps in a unified direction without manual sorting; then, the automatic capping device accurately covers the cap on the pouch mouth, combined with the no-cap detection function. If there is a missing cap, the equipment stops immediately to prevent uncapped products from entering the next link.<\/span><\/span>\u200b<\/span><\/div>\n
4. Electromagnetic Head + Gear Capping (Servo Capping), Firm and Leak-Proof with Zero Complaints<\/span><\/span>\u200b<\/span><\/div>\n
The capping link is the key to ensuring packaging quality. The LY-ZLD series equipment adopts <\/span><\/span>dual technology of electromagnetic head + gear capping (servo capping)<\/span><\/span>, which can automatically adjust the capping force according to different cap types (such as threaded caps and snap caps) to ensure that the capping is firm without damaging the cap and pouch mouth. Tests show that the qualified rate of capping of the equipment is 99.8%, and the liquid leakage rate is less than 0.2%, completely solving the problem of “loose capping leading to liquid leakage and over-tight capping leading to damage” in traditional manual capping, and the customer complaint rate has decreased by more than 90%.<\/span><\/span>\u200b<\/span><\/div>\n
From automatic pouch hanging to finished product discharge, the LY-ZLD series equipment can complete 800-1500 pouches of packaging per hour, which is 5-8 times more efficient than manual work. At the same time, it reduces the input of 6-7 workers and saves enterprises more than 150,000 yuan in labor costs per year.<\/span><\/span>\u200b<\/span><\/div>\n
3. High-Precision and Stable Operation, Reducing Loss and Improving Product Competitiveness<\/span><\/span>\u200b<\/span><\/div>\n
The LY-ZLD series stand-up pouch filling and capping machine ensures long-term stable operation of the equipment through multiple technical designs, reduces losses, and improves product quality and market competitiveness.<\/span><\/span>\u200b<\/span><\/div>\n
In terms of <\/span><\/span>filling precision<\/span><\/span>, the equipment is equipped with an imported load cell to monitor the filling volume in real time. If there is a deviation, it will automatically adjust immediately. The error is controlled within \u00b11ml (low viscosity) and \u00b12g (high viscosity), which is far lower than the industry average error (\u00b15ml\/g), avoiding raw material waste and saving enterprises more than 30,000 yuan in raw material costs per year; in terms of <\/span><\/span>equipment stability<\/span><\/span>, core components (such as filling pumps and capping mechanisms) are made of stainless steel, which is wear-resistant and corrosion-resistant, with a service life of 5-8 years and a failure rate of less than 1%, reducing downtime and maintenance time; in terms of <\/span><\/span>safety guarantee<\/span><\/span>, the equipment meets food-grade standards, and the parts in contact with products are made of 304 stainless steel, which can directly contact food and daily chemical products, without odor and rust, and has passed the national food safety testing certification, making enterprise production more assured.<\/span><\/span>\u200b<\/span><\/div>\n
4. In-Depth Adaptation to Multiple Industries, Becoming the First Choice for Enterprise Packaging Upgrade<\/span><\/span>\u200b<\/span><\/div>\n
With the advantages of “multi-category adaptation and full-process automation”, the LY-ZLD series stand-up pouch filling and capping machine has been widely used in beverage, food, daily chemical and other industries, and has become an “all-round assistant” for packaging of enterprises of different sizes.<\/span><\/span>\u200b<\/span><\/div>\n
