超声波探伤扫描食品软包装袋封边缺陷的初步研究

摘要

Principle of ultrasonic wave non-destructive scan was introduced and ultrasonic wave non-de-structive scan was applied in food flexible packages seal defects-weak seal、channel leak、contamination or inclu-sion seal defect.According as the reflection signal of sound waves,position of the defects in seal can be located.%介绍了超声波探伤检测的原理，并应用超声波检测技术对食品软包装袋封边封口强度低、含泄漏通道和含夹带物等几种缺陷形式进行扫描。通过扫描后的反射波信号，定位封边内的缺陷类型及位置。
