To withstand the rigors of shipping perishable foods wax treatments for corrugated boxes and packaging is often used. Wax is used as treatment, coating, laminate and impregnation of primary food contact materials such as paper, board, and aluminum. Waxes are used in food packaging materials because they have great moisture barrier characteristics. As such, they can reduce moisture loss of wet product, as well as protect dry foods from environmental moisture. Wax coating enables corrugated containers to handle hydro-cooling, top-icing, slush ice injection, high-humidity storage and long distance shipping.
SCHC has exclusive Wax treatments to offer you cost effective, water resistant packaging. Before becoming acquainted with them, it’s useful to know the three most common methods of wax application:
- Wax Impregnation: It imparts a dry wax coating to containerboard during corrugated operations.
- Curtain Coating: It’s applied to flat blanks by passing the sheet horizontally through a thin continuous curtain of polymer-modified wax, which forms a film over the entire surface of the walls of the board.
- Cascading: It’s applied to a box or blank passing vertically through multiple cascades of paraffin-based wax with the objective of saturating the combined board. This is the most water resistant.
SCHC uses these three techniques, sometimes overlapped, plus various paperweights and unusual box shapes, to ensure you have as much protection, leakage-resistant, long distance resistance, stacking strength and large load capacity as each one of your products requires.
These are the SCHC exclusive Wax treatments:
