An article by admin    1 Comment

Moisture-proof Package are important for package quality, moisture-proof package quality control is therefore, very necessary. Moisture proof package is widely used in machinery, electronics, foodstuff, medicine and daily care, etc. It is a most commonly used protection against moisture during logistics. Moisture proof package avoids rusts and deterioration of the packed contents effectively. Labthink, as the excellent provider of testing instruments and testing services, integrates moisture proof methods with relevant methods for introduction.

• Heat Seal Strength Testing for Moisture-proof

The heat seal strength of the moisture proof packages should be no less than 30N/5cm according to some standards.

Labthink HST-H3 Heat Seal Tester is for the specimen preparation of the heat seal testing procedures. Tensile tester is to separate the seal so as to test heat seal strength.

Labthink XLW series tensile testers are specialized in the heat seal strength testing for moisture proof packages. A full automatic testing can be accomplished only by pressing the button ‘Heat Seal Strength’. Besides, this tester can test the elongation, peeling strength, tearing strength and puncture of the laminated layers of the moisture proof package.

• The Seal Performance Testing of Moisture-proof Packages

The seal performance testing of moisture-proof package can be accomplished with Labthink MFY-01 Leak Tester. This tester consists of mainframe, vacuuming device and vacuum chamber. Through testing, pinhole, crack, inferior seal and other defects can be found.

First, place the package into the vacuum chamber filled with water, set the vacuum maintaining time between 30 to 60 seconds. The vacuum rate is set as one of the following: 20, 30, 50 or 90kPa. Then, start testing to achieve preset vacuum rate and maintain the vacuum maintaining time. Observe the leakage during vacuuming and vacuum maintaining periods so as to see if there are bubbles. A single separated bubble can not be regarded as specimen leakage.

The above is a brief introduction on packaging testing standards and methods as well as testers. Labthink is willing to share more with you in quality control and testing solutions.
