Detection method of thermal sealing strength of medical plastic suction box - 1

Detection method of thermal sealing strength of medical plastic suction box Abstract: Plastic suction packaging is a common kind of medical pharmaceutical packaging at present, with its strong protection, good sterilization effect, long storage period. It reduces loss and costs, and is easy to use. Based on those advantages, there have been more and more applications for it. In the performance indicators of plastic suction packaging box, thermal sealing strength is one of the most important. Its strength directly affects the quality of packaging. In this paper, C610 (M) Auto Tensile Tester, independently developed by Labthink Instruments Co., Ltd. is used to test the thermal sealing strength of the medical plastic suction box, and briefly describes the principle, parameters and specific test process of the equipment, so as to provide reference for the pharmaceutical packaging industry to monitor the thermal sealing strength of plastic suction packaging. Key words: thermal sealing strength, sealing strength, heat sealing strength, paper and plastic packaging, plastic suction packaging 1. Significance Medical suction plastic packaging is generally composed of two sides. One side is a permeable paper permeating and discharging sterilization factors, and the other side is a transparent composite film or hard suction plastic tray. In the process of sterilization, the permeable paper allows steam to permeate, so as to achieve the purpose of sterilizing the internal, the sterilized paper-plastic packaging box can effectively prevent the invasion of bacteria, and the plastic is clearly visible to the packed contents, which is easy to use and manage. Under the standard of ensuring that the barrier conditions between the paper surface and the thermoplastic surface meets the requirements, the thermal sealing strength has become an important factor affecting the packaging quality. Thermal sealing requirements are clearly specified in the 5.7.10 package requirements of 5.7 packaging in WS310.2-2016 Hospital Disinfection Supply Center, Part 2: Technical Operation Specification for Cleaning, Disinfection and Sterilization.

Figure 2 C610 (M) Auto Tensile Tester 4.1 Equipment Principle The sample is clamped between the two clamps of the tester, and the two clamps do relative movement. Through the force value sensor and the displacement sensor built in the instrument, the force value and displacement changes during the test, so as to calculate the thermal sealing strength, peel, stretch, tear, deformation and other performance indicators of the sample. 4.2 Scope of Applications Basic application of test items: tensile strength and deformation rate, tension-to-break force, thermal sealing strength performance,...
