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, [...]

BB/T0024-2004 Stretch Wrap Films for Transport Packaging came into implementation on June 1, 2006. This standard adopts ASTM D4649 – 03(2009) Standard Guide for Selection and Use of Stretch Wrap Films.

OLED, Organic Light Emitting Display, has found its wide applications in many industries because of its advantages as slimness, low temperature display, low cost and self-lighting. However, the organic light emitting material of OLED is sensitive to water molecule; and excessive water molecule transmission would affect the life span of OLED. This has been a great obstacle for the further development of OLED. Thus, how to test the molecule permeability of OLED film and sheet [...]

Volatile Corrosion Inhibition (VCI) has found its wild application, and has completely promoted metal antirust from grease. Now, in the field for high quality rust-proof applications, including military, precision machinery, ironware, measuring and blade wares, electric and electronic applications, machinery processing, storage and voyage as well as high requirements for export goods, VCI packages have got more applications. The principle of volatile corrosion inhibition is by using VCI, volatile corrosion inhibitor which can be evaporated [...]

VCI(Volatile Corrosion Inhibition) package has found its wide applications; and its barrier property performance has become an important factor in VCI quality control. The principle of volatile corrosion inhibition is by using VCI, volatile corrosion inhibitor which can be evaporated under normal temperature so as to achieve saturation in the closed environment; VCI molecules are absorbed onto the metal surface to form a transparent protection film of several molecules thick after complicated physical and chemical [...]

Medical protective clothing testing is of vital importance for medical protective clothing quality. Medical Protective clothing testing mainly includes following items: barrier property testing (gas transmission quantity testing and moisture transmission testing), coefficient of friction (smoothness of material surfaces), tensile and elongation, peeling strength, heat seal strength, leak & seal, tearing and printing quality testing. Labthink Instruments Co. Ltd., meeting the demands for medical protective clothing testing, integrates medical protective clothing instruments as follows, so [...]

Moisture proof package is for protection against moisture during logistics. 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. The moisture proof packages are tested according [...]

Puncture performances is the most important testing item for butyl rubber plugs testing puncture force and fragmentation property.

Permeation is one of the indexes indicates the barrier properties in material field. In packaging material industry, permeation is used to state and evaluate the barrier property of packaging materials against water vapor, oxygen or other gases, etc.; that is, through the evaluation of water vapor transmission rate (WVTR) testing, oxygen transmission rate (OTR) and other gas transmission rate (GTR) testing of packaging materials, the basic guarantee for product quality and shelf-life period is confirmed. More questions for Permeation, please visit www.labthink.cn for answers.

WVTR is the abbreviation for water vapor transmission rate, which is defined as the constant rate at which water vapor permeates through a specimen film at specified conditions of temperature and relative humidity.
