How to roll and pack
To roll pack the mattress, several procedures are possible. Inline productions often include a packaging machine at the end.
Normally, the mattress is pressed, vacuumed, and packed into an airtight foil while flat. Afterwards, it is rolled, put into a bag, and tightly closed. Because the inner foil is not airtight over a long period, the vacuum slowly fades. But due to the outer bag, the mattress keeps its shape.
The benefits of this option are its simplicity, the small tension on the glue because of the flat vacuuming, and especially the suitability for spring core mattresses.
A disadvantage is the big amount of plastic used if the inner foil and outer bag are both made of plastic. But there are already alternatives such as bags made of strong paper or textile materials. These materials are more challenging because they are not naturally water resistant, but they are much more eco-friendly. The paper bags can even be disposed of with wastepaper.
