Food Packaging Maintain The Ability To Produce Qualified Products Continuously Oct 11, 2017

The quality and safety of food directly affects national health, packaging as an important part of food, in the product after the factory to play an important role in quality protection. Jinan Lan light combined with the relevant provisions of the existing food packaging packaging test items, and a brief introduction to the corresponding detection equipment.

Food Packaging as the current mainstream packaging, is widely used in various types of goods packaging, especially in the food industry applications up. Our daily consumption of liquid / semi-liquid food, powdered food, solid food, etc. are mainly Food Packaging. Commonly used food packaging materials used in polyethylene, polyvinyl chloride, polypropylene, polyester, polyvinylidene chloride and polycarbonate; different materials due to their different characteristics of its application is different, we usually use the material according to actual needs Of the different characteristics of its complex together to use.

The quality and safety of food directly affects national health, packaging as an important part of food, in the product after the factory to play an important role in quality protection. Especially with the "Food Safety Law" introduced, the food industry is no longer only concerned about the safety of food, food packaging safety is equally important. China's State Administration of Quality Supervision in 2006 to start food packaging QS certification and market access work, the use of Food Packaging products for food production license and market access system. Food packaging products should be consistent with the "food packaging containers and other products with the production license" and "food packaging containers and other products with the production license approval rules" requirements; related enterprises should be based on product applications to test the performance of packaging And evaluation to ensure the ability to maintain a continuous production of qualified products.

Barrier performance refers to the packaging material on the gas, liquid and other permeate barrier effect. Barrier performance tests include testing of gas (oxygen, nitrogen, carbon dioxide, etc.) and water vapor transmission properties. Barrier performance is an important factor affecting the quality of the product during the shelf life. It is also an important reference for the analysis of the shelf life. Through this test, it can solve the problems such as oxidation and deterioration caused by oxygen or water vapor sensitivity.

At present, the industry commonly used gas barrier performance testing equipment is divided into two test principles - pressure method and isobaric method. 

Food packaging materials or containers of water vapor barrier performance testing is selected with moisture permeability equipment. Common test principle that is cup and sensor method, in which the principle of sensor equipment, including electrical sensor method, infrared sensor method and humidity sensor method three.
