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 [...]

Strength testing includes index testing like material tensile strength testing, peeling strength testing of laminated films, hot seal strength testing, tearing strength and pouch resistance testing. Tensile strength is the maximum strength value just before the material is snapped. Through testing, the package damage and rapture caused by external forces and insufficient packaging material mechanical strength can be resolved effectively. Peeling strength testing, also called complex strength testing, tests the bond strength between the layers [...]

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. [...]

MRE (Meal-Ready-to-Eat) is an important field of food research. Owing to its specialty, there are more strict requirements for MRE processing, nutrition and packaging. MRE requires long-term safe and clean storage as well as good packaging seal performance. Those characteristics determine the strict packaging requirements for MRE. As to the quality control and testing items, Labthink Instruments Co. Ltd. (www.labthink.cn) introduces as follows： Heat Seal Strength Testing MRE package heat seal strength testing tests the [...]

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 [...]
