The Soft Bag Large Infusion Production Line is a fully automatic, integrated sterile production system specially designed for the continuous production of large-volume soft bag infusions. It integrates seamless linkage of key processes, including film unwinding, bag forming, filling, sealing, leak testing, labeling, coding and packaging. Complying with GMP, FDA and CE standards, it is widely applied in the pharmaceutical industry for the production of normal saline, glucose injections, nutrient infusions and other large-volume sterile preparations, featuring high automation, strict sterility control and stable operation.
1. Core Structure and Working Principle
Adopting a modular integrated design, the line consists of film processing module, bag forming module, filling-sealing module, inspection module and packaging module, all connected seamlessly. Controlled by an advanced PLC touch screen system, it realizes synchronous operation of all modules, realizing full-process automatic production with minimal manual intervention. The core principle is to complete the entire production process in a closed sterile laminar flow environment, from film unwinding to finished product packaging, effectively avoiding product contamination and ensuring the safety and consistency of large infusion products.
2. Key Functions and Technical Features
Film Unwinding & Bag Forming: Automatic unwinding of medical-grade composite film, precision heat-sealing forming, compatible with various soft bag specifications (100ml-1000ml), with uniform sealing and no leakage.
Precision Filling: Equipped with high-precision metering pumps, filling volume is adjustable, filling accuracy ≤±0.5%, suitable for different viscosity infusion liquids, with anti-dripping design to avoid waste and contamination.
Sterile Sealing & Leak Testing: Double heat-sealing technology ensures tight sealing; online vacuum leak testing automatically detects unqualified products (leakage, incomplete sealing) and rejects them in time.
Labeling & Coding: Automatic labeling with high positioning accuracy, laser/inkjet coding to print production date, batch number and expiration date, realizing full traceability of products.
Automatic Packaging: Integrated with automatic bagging and cartoning functions, improving packaging efficiency and ensuring the cleanliness of finished products.
3. Core Advantages
High Sterility: Closed sterile production environment, HEPA high-efficiency filtration, all contact parts made of 316L stainless steel and pharmaceutical-grade materials, meeting strict sterile requirements of large infusions.
Full Automation: Full-process automatic operation, reducing manual intervention, lowering human error, and improving production efficiency and product stability.
Strong Versatility: Compatible with multiple soft bag specifications (100ml-1000ml) and various infusion formulas, customizable to meet different production needs.
Stable Performance: Modular design, easy maintenance and calibration, stable operation for long periods, reducing production downtime.
Compliance & Traceability: Full compliance with GMP and international pharmaceutical standards, real-time recording of production parameters, ensuring product traceability and regulatory compliance.
4. Application Scope
This production line is mainly used for the sterile production of large-volume soft bag infusions in the pharmaceutical industry, including normal saline, glucose injection, amino acid infusion, fat emulsion, and other therapeutic and nutrient infusions. It is the core equipment for pharmaceutical enterprises to realize standardized, efficient and sterile production of soft bag large infusions, helping enterprises improve production efficiency and market competitiveness.
