Gum wrappers, specifically the inner ones that directly enclose the chewing gum stick, are primarily produced from a specialized material designed to protect the gum's freshness and texture. The core material used is aluminum paper laminate.
The Core Structure: Aluminum Paper Laminate
The foundation of a gum wrapper is aluminum paper laminate. This material combines layers of aluminum foil and paper, providing a barrier that helps preserve the gum. The aluminum layer is crucial for preventing moisture and oxygen from reaching the gum, while the paper layer provides structure and a surface for printing.
Sealing and Application
To ensure the layers are bound together and to facilitate wrapping the gum, an application of wax or glue is used on the laminate. This adhesive or wax layer helps in the folding and sealing process, keeping the gum securely enclosed.
Finishing and Decoration
The visible side of the wrapper can undergo several finishing processes to add branding and visual appeal. These include:
- Lacquering: Applying a protective coating.
- Printing: Adding logos, text, and designs.
- Embossing: Creating raised patterns or text for tactile interest and branding.
These steps allow manufacturers to create distinctive and informative packaging.
Modern Alternatives
In addition to the traditional laminate with wax or glue, newer innovations exist. One example mentioned is FoldAdLam, which is highlighted as a wax-free laminate. This suggests ongoing development in packaging materials to potentially improve environmental impact or performance.
In summary, the production of inner gum wrappers involves creating an aluminum paper laminate, applying wax or glue, and finishing it with lacquering, printing, and/or embossing.
