I. Introduction
Polyolefin filmsis a film material made from polyolefin-based plastics that is commonly used in packaging, protection, and other applications. Polyolefin films have excellent mechanical properties, chemical resistance, and heat sealing properties, so they are inFood packagingMedical device packagingAgricultural coverbuilding materialsand other fields have been widely used. A large infusion bag is a medical device used for infusion, usually to deliver medication or saline into a patient's body. These bags are usually made of polyolefin film, which is capable of holding large volumes of liquids and has some durability and safety.
2. The working principle of the elongation test of large infusion bags (polyolefin films).
The elongation test of large infusion bags (polyolefin films) is used to evaluate the elongation of the bag when stressed. The test is usually carried out by applying a certain pull force to both ends of the bag and then measuring the degree of deformation of the bag under the action of the pull force.
During the test, one end of the bag is fixed on the test equipment, and the other end applies a certain pulling force, and then the length change of the bag under the action of the pulling force is measured. By measuring the tensile force and length change, it is possible to calculate the elongation of the bag, which is the percentage increase in the length of the bag under a certain tensile force.
