It supports flexible production of multi-specification products, effectively improving line efficiency and reducing production and maintenance costs.

Application Scenarios: Continuous horizontal sealing packaging for regular solid products such as blocks, strips and tray-type goods (bread, biscuits, candy, medicine, masks, hardware accessories, daily necessities, frozen food, etc.).

1. Customer Pain Points and Demand Analysis

Combined with actual industrial mass production scenarios, traditional horizontal packaging has four major pain points: high labor dependence, low packaging yield, low efficiency of multi-SKU switching, poor stability in high-speed operation, and untraceable production data, which cannot meet modern lean production standards.

High labor dependence: Manual film wrapping, sorting and counting lead to high labor costs, limited shift production capacity, and poor packaging consistency caused by human errors.
High defective packaging rate: Traditional mechanical speed regulation structures easily cause film length deviation, wrinkled and leaking seals, cutting offset and product extrusion damage, keeping the defective rate at a high level.
Low product switching efficiency: Traditional machines depend on mechanical gear adjustment. Multi-SKU switching is time-consuming and requires professional debugging, which cannot adapt to small-batch and multi-variety orders.
Unstable equipment operation: High-speed operation is prone to faults such as film deviation, film breakage, material jamming, empty packaging and mis-cutting, resulting in frequent shutdown debugging and greatly reduced equipment utilization rate.
Untraceable production data: Without automatic output statistics, fault records and parameter storage functions, production data is scattered and fails to meet the standards of lean production and quality traceability.

Based on the above pain points, the core customer requirements are to realize full-automatic continuous packaging, ensure stable high-speed production, support one-click fast model switching, reduce defective rate, simplify operation and maintenance, and realize seamless connection with automatic production lines and quality traceability systems.
