Metalised multiple layer plastic packaging especially for perishable foodstuffs incorporating a barrier layer with gas and UV blocking properties

摘要

An improved plastic food packaging system has a multi-layer construction with partial metalising for modified atmosphere packaging (MAP) incorporating a barrier layer (B) which blocks gasses and aroma as well as UV. The multi layer polymer construction is sandwiched between outer sealing layers (S) and includes support layers (T), a printed layer (D) and partial metalising, e.g. evaporated aluminium.
