Carbonless paper roll a chemical reaction between two different uses.

Carbonless paper used a chemical reaction between two different coatings, contact to transfer a picture when pressure is applied. A paper that is used most often for multiple part forms contains a chemical coating on the front that (CF known as) on the back (known as CB) or on both sides (called CFB). When occurs a handwritten or machine impression on the first sheet of several parts, dark copy of the impression used the impression posts from a page or ply to the next due to the bursting of the tiny microcapsules in the chemical coating release on the first page.

Provided a method and apparatus for making one wrapped foam package to protect of a role of the pressure-sensitive carbonless paper.. Interleaved foam and film that the roles and separate feeding packaging foam are energized to the outer periphery of the role of carbonless paper by selectively turning and stretch film roll towards the rotating.

The present invention refers to a procedure for the production of a foam wrap package and more especially, to a process for packaging and protecting a paper roll of pressure carbonless paper copy by simultaneously interleaved layers of stretch film and packaging foam on the role of carbonless paper wrapping.

So far, manufacturers stretch wrapping equipment have the spiral wrapping silage stretch film with limited non spiral wrap of a single face corrugated medium or a power wrap combines marketed. Traditional machines have been developed, the foam wrap in a single operation provide and then wrap in a second task force, and have needed a considerable amount of the wrapping process by hand be carried out.

Problems have arisen in the State of the art with the existing foam/force packages. In particular can not these packages that produce power wrap apply foam over the edge of a role of the pressure carbonless paper without a bulky edge roll stack makes difficult. The lack of foam over the edge leaving role of carbonless paper roll that subject to edge damage. Prior to this time, sufficient packaging procedure, or a final wrapped package in art has been achieved, would require only a relatively limited capital costs and produce a resulting packaged product easy to use.
