The purpose of food package testing is to check whether the packaging materials are processable, and to guarantee the package can protect the food. Protection includes to guarantee the shelflife of the food, the appearance of the package to attrack the consumers’ attention, and to gurantee the packages’ properties during full transmportation. To meet the demands for food packaging testing, and to help the food companies and food packaging companies on quality testing of the [...]

With the wider application of flexible plastic pouches in foodstuff, medical and pharmaceutical industries, the heat seal quality of the plastic pouches is of great significance in the content protection, shelf-life guarantee and good display status, etc. In order to test the heat seal property of plastic pouches, Labthink Instruments Co., Ltd. introduces Labthink PARAM HTT-L1 Hot Tack Tester. This hot tack tester complies with ASTM F1921, ASTM F 2029 and many other international standards. [...]

The mechanical performance of cosmetic package plays an important role in the packaging & processing, transportation and shelf life. Its quality directly affects cosmetics safety during distribution. The testing items include: tensile strength & elongation rate, peeling strength of laminated films, heat seal strength, sealing and leakage, impact resistance and surface smoothness, etc. 1. Tensile Strength and Elongation, Peeling Strength, Heat Seal Strength and Tearing Performance Tensile strength is the maximum force before material breakage [...]

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 [...]

Heat seal strength is one of significance properties  for  BOPP Cigarette film quality control. BOPP films require high heat seal strength and wider heat seal scope by the cigarette industry, so as to improve packing speed and proper operation. However, if the heat seal temperature is higher, it would lead to wrinkle because of increased BOPP film shrinkage. Therefore, proper heat seal temperature should be chosen so as to avoid unstable heat seal, wrinkle and [...]
