Ration Package Heat Seal Strength Testing

May 8, 2009 - PRLog -- Ration is an important field of food research. Owing to its specialty, there are more strict requirements for ration processing, nutrition and packaging. Ratopm requires long-term safe and clean storage as well as good packaging seal performance. Those characteristics determine the strict packaging requirements for ration. As to the quality control and testing items, Labthink Instruments Co. Ltd. (www.labthink.cn) introduces as follows:
 Ration package heat seal strength testing tests the heat seal parts of the ration package such as the top, bottom and back sides of the package. Cut specimen in the vertical direction from the heat seal places, as the heat seal specimens for top, bottom and back parts. The specimens are required to be 15+/-0.1mm, and spread length of 100+/-1mm. If the length can not be reached, cellophane can be applied to connect the same material to reach the length.
 Take the heat seal place as the centre line, and spread the package flat, clamp the specimen onto the clamps of Labthink PARAM (PC) -500 Auto Tensile Tester. The ordinate axis of the specimen should be in compliance with the centre line of the clamps with proper tightness. The initial distance between clamps should be 50mm. The testing speed is 300mm/min. Start testing and calculate the heat seal strength with the average of 10 specimens in the unit of N/15mm with 3 significant figures. One thing should be cautious is that if the specimen is broken during testing, it should be replaced by a new one.
 HST-H3 Heat Seal Tester can simulate the testing conditions for ration packaging line in lab research. The above two testers can achieve specimen preparation and testing.
