Innovative Pressure-Sensitive Carbonless Paper Roll: Eliminating Bulky Edges
Overview
A groundbreaking method has been developed to wrap carbonless paper rolls using interleaved foam and film, eliminating bulky edges. By rotating the roll and applying tension, the foam and film are tightly wrapped around it.
What is Carbonless Paper?
Carbonless paper facilitates image transfer through a chemical reaction between coatings on its sheets. Typically used for multi-part forms, the paper has coatings on the front (CF), back (CB), or both (CFB) sides. Pressure bursts tiny microcapsules, creating a duplicate impression on subsequent sheets.
New Wrapping Method
The innovative process involves a method and apparatus for wrapping carbonless paper rolls with foam under tension. By rotating the roll and feeding packaging foam and stretch film, the roll is effectively protected without creating bulky edges.
This invention revolutionizes the wrapping of pressure-sensitive carbonless paper rolls by simultaneously applying interleaved layers of stretch film and foam, enhancing protection and ease of handling.
Overcoming Traditional Limitations
Conventional machines combined spiral stretch film wrapping with manual kraft wrap applications, causing challenges. These methods led to bulky edges, complicating stacked storage and leaving edges vulnerable to damage.
Previous techniques couldn't apply foam over the edges without creating bulk. This often resulted in edge damage, compromising the paper's integrity. Until now, no efficient, low-cost wrapping solution existed that was both protective and easy to handle.
Conclusion
This innovative wrapping process for carbonless paper rolls reduces bulk and enhances protection. By ensuring no bulky edges, it simplifies storage and handling, setting a new standard in paper roll packaging.
