Laminated materials can be used for “aggressive”, corrosive products or those that require additional processing such as cooking or hot fill contents.
Laminated lids can also offer a welded (un-peelable) seal so are also an ideal solution for chemical-type products.
The flexibility of laminate lids means that they can also offer an easy peel that works well for food packaging where the end user requires a good peel with a reduced risk of tearing the lid.
Laminates can offer a total barrier against water vapour & oxygen transmission as well as light and aroma. This makes them ideal choice for sensitive and extended shelf life products.
