Food packaging sealing techniques |

In [[Food packaging]], sealing can be defined as a joining process consisting in the permanent attachment of two or more surfaces of polymeric materials by the controlled application of a thermal, mechanical, or [[Electromagnetic radiation|electromagnetic radiation]] source, with or without pressure, such as to cause surface melting of the materials, in order to achieve a hermetic, mechanically stable closure suitable for the protection of the [[goods]]. |

To achieve proper sealing, several methods can be employed, depending on the type of product to be protected, the material’s compatibility, and the desired [[shelf life]]. |
