Before putting much faith in a Chinese factory's test results it makes sense to ensure that the laboratory which conducted the tests has a China laboratory accreditation certificate. Although many factory's have their own laboratories, few of these are independently certified so requesting testing by external testing body is a wise move in many circumstances. These testing bodies should be accredited and you can make sure of this by requesting a copy of their China laboratory accreditation certificate. What is a China Laboratory Accreditation Certificate? The China laboratory accreditation certificate is a certificate issued to test laboratories in Mainland China which have been deemed to conform to the requirements of international laboratory standard ISO/IEC 17025. The certificate is issued in two versions, one in Chinese and the other in English. Either way, the certificate is easily recognizable thanks to the prominently displayed "ilac-MRA" and "CNAS" logos. What Information is Contained in a China Laboratory Accreditation Certificate? China laboratory accreditation certificates are only issued by the China National Accreditation Service for Conformity Assessment (CNAS) and should be similar in appearance to the certificates above. Who Issues a China Laboratory Accreditation Certificate? As Mainland China's only signatory to the International Laboratory Accreditation Cooperation (ILAC) under the Mutual Recognition Arrangement (MRA), CNAS is the only authority which can issue China laboratory accreditation certificates. International Mutual Recognition China national accreditation system for conformity assessment has been a part of international accreditation multilateral recognition system, and is playing an important role in it. CNAS was the accreditation body member of International Accreditation Forum (IAF) and International Laboratory Accreditation Cooperation (ILAC)，as well as the member of Asia Pacific Laboratory Accreditation Cooperation (APLAC) and Pacific Accreditation Cooperation (PAC) GBPI CNAS Laboratory supply water vapor permeability testing,oxygen transmission rate testing,tensile testing,coefficient of friction testing,leakage testing,heat sealing testing etc.

In the food packaging industry, using a material composition that extends shelf life is a key component to ensuring the safety of the product and preserving the taste of the food. In addition, using packaging material that prolongs a products shelf life can drastically cut down on waste of perishable products, and creates a longer window for grocery stores to stock product before it reaches the hands of the consumer. A great way to achieve this is by using a packaging material that reduces the amount of oxygen that permeates the plastic, such as EVOH. So what is EVOH film and how does it contribute to increasing the shelf life of packaged food products? EVOH stands for Ethylene-vinyl alcohol copolymer and is a flexible, crystal clear, glossy thermoplastic copolymer. This material has excellent flex-crack resistance, and exhibits a high resistance to hydrocarbons, oils and organic solvents. EVOH is known for having some of the best barrier resistance to gases such as oxygen, nitrogen, and carbon dioxide which makes it particularly suited for packaging food, drugs, cosmetics, and other perishable products. When compared to other common films, EVOH is considered to have superior barrier properties. You might be thinking so how to test EVOH oxygen transmission rate.GBPI Oxygen Permeability Analyzer Y110 help you find out the answer.This oxygen permeation tester is our GBPI design for EVOH Barrier film oxygen transmission rate testing,popular for our EVOH Barrier material customers.
