Abstract Basically, increasing the thickness of film materials is one of the important measures to improve the barrier properties of packages. Meanwhile, the increase of materials thickness is bound to increase packaging costs. This article studied the influence of increasing the thickness of single layer membrane in composite materials on the barrier properties of packages, through test the oxygen permeation of film materials with different thickness. Keywords Film materials, thickness, barrier properties, oxygen transmission rate, [...]

Abstract: hazardous gas is a potential threat to mine safety, and the application of sealing materials is one of the effective methods to reduce the concentration of hazardous gas in the mine. Based on the test of sealing performance of hazardous gas sealing material in mine, this paper evaluates its sealing ability to hazardous gas, and introduces the parameters, application and test process of VAC-V2 Differential Pressure Gas Permeability Tester based on test principles, so [...]

Abstract: In order to verify whether the substrate material will affect the barrier properties of the aluminized film, we tested aluminized films made of PET and BOPP in similar thickness with a coulometric sensor method oxygen transmission rate testing instrument, C230G Oxygen Transmission Rate Test System. This article is to introduce the test principle, technical specifications, and application scope of the testing instrument as well as the detailed testing procedure. This may help in provide [...]

Most people are familiar with Li-ion batteries, which are widely used in electronic products such as electric automobile and industrial energy reserve. However, except those specialists, few people know about the internal structure of Li-ion batteries. Despite of its shape, a Li-ion battery is composed of positive electrode, negative electrode, diaphragm and electrolyte. Li-ion battery works mainly by the movement of li-ions between positive electrode and negative electrode. When a battery is charging up, li-ions [...]

ABSTRACT Pudding cups need to have effective oxygen barrier properties to guarantee the quality of its shelf life. This article introduces an oxygen transmission rate test method to test the pudding cup, i.e. the coulometric method. The test principle, instrument features, specifications, and testing procedures are all included in this article, which may provide reference for oxygen permeability test of packaging containers. Significance and Use Cup shaped containers are used to pack pudding products to [...]

Dairy products as the daily necessity, plays more and more important role in our life. Many dairy manufacturers, in order to meet the demands of customers, promote new products with new packages. The flexible package quality control of dairy products, thus, becomes more prominent. Hereinafter is the introduction to the flexible package quality control and analysis. 1. The Testing and Analysis of the Composite/Bond Strength of Dairy Packaging Materials The flexible packages of dairy products, [...]

Medical protective clothing strength testing is of great importance. Medical protective clothing 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, [...]

Heat seal strength testing is of great importance to moisture proof package. 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. 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 [...]
