Application of quality inspection instrument for medical infusion bag packaging
With the rapid development of flexible packaging industry, film materials have been widely used and developed in infusion industry Soft package infusion bag is gradually replacing glass infusion bottle Application of quality inspection instrument for medical infusion bag packaging Application of quality inspection instrument for medical infusion bag packaging Application of quality inspection instrument for medical infusion bag packaging Application of quality inspection instrument for medical infusion bag packaging
As early as the 1980s, China began to study the use of polymer plastics to make infusion packaging. At first, PVC soft packaging infusion bags were widely used. This kind of products developed rapidly because of its characteristics of no falling off, light weight and strong impact resistance. However, PVC soft packaging bag materials contain PVC monomer, which is not conducive to human health and is not easy to process Its high oxygen and water vapor permeability and poor tensile strength greatly limit its application in infusion packaging
In this case, the polyolefin multilayer coextrusion film is produced by melt extrusion at the same time The instability and pollution caused by drilling agent are eliminated. It also increases the heat sealing and drop resistance of the membrane material. For water vapor, oxygen, nitrogen and other anion barrier performance: at present, coextrusion film material with its unique advantages in the whole infusion packaging industry accounted for more and more proportion, and its product quality control problems are more and more prominent. The research and control of air permeability and moisture permeability of infusion bag membrane material is particularly important in the infusion soft packaging industry, which will directly affect the product quality. The air permeability tester and moisture permeability tester will be described later, and the importance of the following test data will be emphatically explained.
1、 Friction coefficient test:
Through the test of friction coefficient of packaging material, we can control and adjust the opening of infusion bag and packaging speed of packaging machine For membrane manufacturers, the type and content of opening agent and smooth agent in resin can be selected to control the dynamic and static friction coefficient of membrane material by testing. Mxd-01 model provided by Jinan Chenchi instrument Film friction coefficient tester It has unique oscillation coefficient setting, which is suitable for intelligent data processing of different materials. The large screen liquid crystal displays the curve in real time to directly judge the uniformity of friction coefficient of material surface.
2、 Test of heat sealing strength:
The heat sealing strength is an important performance index for the film material of infusion bag. In order to achieve the packaging purpose, the sealing must have a certain strength to withstand the effect of the internal contents and external pressure, so as to ensure no cracking and damage in the circulation process. For the detection of this index, two kinds of instruments are needed for comprehensive test, one of which is specially used for heat sealing sample preparation, The other instrument needs to test the heat sealing strength.
1、 Heat seal tester In order to meet the needs of different levels of customers, Jinan Chenchi instrument provides two types of heat sealing instruments, model of sth-3 and sth-5. Both instruments are controlled by microcomputer, so that the temperature, time and pressure of heat seal are accurate and reliable. The core components are imported components, which ensure the long-term performance of the instrument.
2、 Electronic tensile machine It can be used to test the heat sealing performance of membrane materials, and the equipment is fully automatic controlled by computer. Group statistical analysis test can be carried out by automatic judgment of shutdown and automatic return of fixture. LCD menu interface, users only need to select the corresponding test items, the instrument can automatically complete such functions as tensile strength and elongation, heat sealing strength, tear strength, peel strength, modulus of elasticity, constant elongation stress and other functions.
3、 Sealing performance test:
Sealing performance is also an important indicator of packaging, sealing also has a great impact on the quality of products, poor sealing is the main cause of leakage in the future. In the sealing test, mfy-01 model of Jinan Chenchi instrument is widely used in the industry Sealing tester 、 Packaging sealing tester According to the principle of vacuum, the instrument maintains a predetermined time under the action of corresponding pressure according to the national standard. The leakage is observed during the test by visual inspection method. The quality of infusion bag packaging can be measured by the measurement of the sealing property, and then the rationality of the sealing process can be determined.
The core factor that coextrusion film material can replace glass bottle packaging is that the coextrusion film material can achieve almost the same high barrier performance as glass bottle packaging. In order to ensure the uniform and stable barrier performance of membrane materials, it is necessary to strictly control the thickness of membrane materials* At the beginning of the industry, micrometer or some point contact thickness gauge are mainly used for control, but this is far from meeting the requirements of the industry for thickness control. According to gb6672 and corresponding international and American standards, mechanical contact measurement must be used for testing, such as hd-04 desktop thickness gauge of Jinan Chenchi instrument.
In the actual production, it is very important to adjust the production process and improve the product quality. Through the corresponding test equipment, to control and master the more reasonable technical parameters, can be used in production, quality control, cost saving.
