JIS K 7113 Disposable Plastics Melt Flow Rate Testing
The JIS K 7113 standard specifies the method for determining the melt flow rate of thermoplastic materials, including various types of disposable plastics. This test is crucial in ensuring that the plastic products meet the required performance standards and can be manufactured efficiently under specified conditions.
Melt Flow Rate (MFR) testing evaluates a material's ability to flow when subjected to shear stress at a given temperature and load. It provides valuable insights into the processability and quality of thermoplastics, which is particularly important for disposable plastics used in single-use applications such as medical devices, food packaging, and consumer goods.
The test involves heating the plastic sample to its melting point and then forcing it through a die or extrusion screw under controlled conditions. The flow rate of the melted material is measured over time, typically at two different load settings (2160 g and 4537 g). These values are used to calculate the MFR index, which reflects the ease with which the plastic can be processed into a desired shape or form.
The JIS K 7113 standard ensures that all testing is conducted under standardized conditions. This includes precise temperature control (190°C ± 2°C for most plastics), load application, and measurement time. The test results are highly repeatable and reproducible, making it a reliable method for quality assurance in the production of disposable plastics.
Understanding MFR is essential for optimizing manufacturing processes. By determining the appropriate MFR for a specific plastic type, manufacturers can fine-tune their processing techniques to achieve optimal performance without compromising on product quality or cost-efficiency. This testing also helps in identifying any inconsistencies in raw material quality that could affect final product characteristics.
For instance, in the medical device industry, accurate MFR testing ensures that catheters and other disposable components are manufactured from materials that can withstand sterilization processes while maintaining their integrity. In food packaging, it guarantees that films used for sealing containers have sufficient strength but remain flexible enough to be sealed properly during filling operations.
The JIS K 7113 standard is widely recognized in Japan and internationally as a robust method for evaluating the processability of thermoplastics. Compliance with this standard not only enhances product quality but also ensures that manufacturers adhere to stringent international regulations regarding plastic waste management and recycling practices.

Environmental and Sustainability Contributions
The JIS K 7113 Melt Flow Rate test plays a crucial role in promoting environmental sustainability by enabling the development of more efficient recycling processes. By understanding how different plastics behave under various processing conditions, manufacturers can better design products that are easier to recycle at end-of-life.
- Improved recyclability: Understanding material properties helps in designing products with longer lifecycle and ease of disposal.
- Reduced waste generation: Efficient MFR testing leads to optimized product designs that minimize unnecessary raw material usage.
In addition, the test contributes to reducing energy consumption during production. Materials with optimal MFR require less heat input for processing, resulting in lower overall energy costs and reduced carbon footprints.
Moreover, Eurolab supports waste reduction initiatives by offering recycling-focused testing services that help clients understand how their products can be recycled effectively. This not only benefits the environment but also enhances corporate social responsibility efforts.
