Puncture resistant properties of packaging material

Puncture resistant properties of packaging material refers to constitute the material of packaging in a variety of temperature and humidity environment, against sharp objects of different hardness, resistance of the strength, speed and pressure of the ability of comprehensive performance, and bags in the comprehensive guidance of ability to resist hard thing pierced. Why packaging materials need to be puncture resistant characteristic? This is due to a lot of products in the process of production will inevitably produce sharp hard objects, and oppression on bags. Especially in the vacuum bags, material is qualified, puncture resistant characteristics is an important measure. Packaging material resistant to Pierce feature measure is mainly based on GB/T21302 - General principles for 2007 'packaging composite film bag in the puncture resistance test. Puncture resistant characteristics of main parameters are: can bear the biggest pressure per unit area, and can withstand the impact of the speed. Currently on the market also has a lot of thin film resistance to puncture tester, there are also called puncturing resistance tester. Template fixed in tester, the material with different hardness of sharp thorn, put pressure on model, through the force value of sensor and speed sensor, the material of the best puncture resistant characteristic parameter table. Sometimes setting environmental temperature, humidity, setting the standard strength of packaging requirements, and speed, to achieve the strength and speed to stop testing, said this composite standards. Market packaging material resistant to puncture tester of the specifications of the standard, the operation is also each are not identical, the main strength of 0 ~ 300 n, 0 ~ 500 n, the main impact velocity grades are 50 mm/min, 100 mm/min to 500 mm/min, and get the data accuracy is + / - 0. 5. Puncture resistant properties of packaging material standard and test method is that these, hope this useful for your reader. If there are any errors, please contact small make up, the online guide.
