Medical bag: extrusion lines for healthcare applications

Complete systems compliant with industry regulati

Extruded films for flexible devices in clinical settings

Medical bags are essential components for the management, administration and collection of biological fluids in hospital environments. Used in devices for intravenous infusion, peritoneal dialysis, enteral nutrition, catheterisation and post-operative drainage, medical bags must ensure high sealing performance, sterilisation compatibility and compatibility with standard connection systems. The quality of the plastic film used to manufacture them directly affects patient safety and the mechanical strength of the finished product. Bausano extrusion lines for medical bags are designed for the production of technical films in rolls, suitable for welding, uniform in thickness and compliant with international healthcare regulations. Integration with in-line measurement and control systems makes it possible to maintain tight tolerances and consistent performance, even in high-intensity production environments.

Applications of medical bags

Medical bags produced through plastic film extrusion are used for the administration, collection and packaging of fluids and materials in healthcare settings. The most common formats have widths between 80 and 420 mm and thicknesses ranging from 0.1 to 0.65 mm, depending on the application and the selected material. Despite the growing use of polyolefins and high-purity polypropylene, plasticised PVC remains one of the reference materials for infusion bags, thanks to its flexibility, transparency and weldability. Medical bags are designed to withstand impact, mechanical stress and heat sterilisation, while maintaining functional integrity and compatibility with the fluids they contain. They are used in a wide range of devices for clinical and veterinary applications, including:

Parenteral nutrition
Administration of rehydration solutions such as sodium chloride, glucose and lactated Ringer’s solution
Packaging of antibiotics and analgesics
Collection of urine and blood for diagnostic use
Safe disposal of biological or contaminated waste
Storage and transport of medicines or medical materials

Bausano extrusion lines for medical film are developed to ensure uniform thickness, constant flatness and reliable weldability, even in continuous cycles and high-output production.

Plastic materials for medical bags: properties and intended uses

In the production and extrusion of medical bags, material selection directly affects flexibility, weldability, mechanical strength and compatibility with the fluids contained. Bausano extrusion lines are designed to process the main plastic materials used in the healthcare sector efficiently, ensuring uniform thickness and process repeatability, even in continuous production cycles.
Commonly used materials include:

Polyethylene (PE) Used for sterile bags and protective packaging, it offers good flexibility and chemical resistance.
Polypropylene (PP) Used in applications that require sealing performance and tear resistance, it is suitable for repeated sterilisation cycles.
Polyvinyl chloride (PVC) Used for infusion bags, it combines transparency, flexibility and compatibility with medical fluids.
Ethylene Vinyl Acetate (EVA) Ideal for urinary drainage bags, thanks to its softness, biocompatibility and flexibility at low temperatures.

Each extrusion line is configured to meet the customer’s quality specifications, ensuring regulatory compliance, production stability and customised film properties according to the clinical use of the device.

Process control and traceability on extrusion lines

In the production of films for medical bags, dimensional stability and process repeatability are essential to ensure the quality of the finished product. Bausano extrusion lines are designed to operate in regulated environments, with integrated systems for in-line measurement, temperature control and automatic vacuum adjustment. Each critical parameter, from film thickness to flatness, is monitored in real time. In addition, complete traceability can be associated with each batch, supporting process validation and document management according to GMP or ISO 13485 procedures.

International compliance and validation support

Medical bags produced with Bausano lines comply with the standards required in the main global markets, including FDA 21 CFR in the United States, ANVISA in Latin America, European Pharmacopoeia, USP Class VI and ISO 10993. To support industrial implementation, the systems can be supplied with complete technical documentation, IQ/OQ protocols, process specifications and support for validation file preparation. This approach reduces audit times, simplifies integration with the customer’s quality systems and accelerates the device’s time to market.
