Description
Technical Field
The invention relates to the field of packaging material performance tests, in particular to a device for testing migration and barrier performance of a dry content packaging material.
Background
Packaging material refers to the generic term for materials used for manufacturing packaging containers and for constituting product packages, such as paper and paperboard, plastics, metals, wood, glass, ceramics, composites, etc. During contact of the packaging material with the contents of the package, certain chemical components contained in the material may migrate into the contents, and certain chemical components in the contents may also migrate through the packaging material into the surrounding environment, eventually possibly affecting the properties of the contents and even causing environmental or human health hazards. Therefore, the migration and barrier properties of the packaging material need to be tested.
The barrier properties of a packaging material refer to the properties that prevent the migration of a substance or substances in the contents of the package through the packaging material into the surrounding environment. The packaging material with excellent barrier property can ensure that the contents can obtain better preservation effect and longer shelf life. At present, the detection of the barrier property of the packaging material is commonly carried out by gas permeability detection (common inorganic gases such as oxygen, nitrogen, carbon dioxide, air and the like) and moisture permeability detection (water vapor), but the detection of the barrier property of some chemical components contained in the content itself, especially volatile semi-volatile compounds, is less.
The migration properties of a packaging material are generally expressed in terms of the amount of migration, which is the amount of a substance or substances in the packaging material that migrate into the contents of the package or into a simulant of the substance or substances with which it is in contact, both in direct and indirect contact. In each regulation and standard, the migration amount is an important index for controlling the limited substances. Taking the food industry as an example, in recent years, at home and abroad, various standards, regulations or documents are issued and implemented in the move quantity test and move quantity limit of food packaging materials in the European Union, the United states, China and the like.
At present, a glass culture dish or a glass weighing dish with a ground opening is generally adopted as a testing device for the migration performance of a dry content packaging material, but the glass culture dish cannot ensure the air tightness, and low-boiling-point substances are easy to dissipate in the experimental process, so that the detection accuracy is influenced; the commercially available glass weighing vessel has certain air tightness, but is not absolute, and the size of the glass weighing vessel does not meet the requirement; in particular, at present, no test device can be used for testing the migration performance of the packaging material containing dry contents and the barrier performance of the packaging material to chemical components in the dry contents.
