Primary vs Secondary Packaging for Chocolate
Primary packaging
Primary packaging is the layer that directly touches the chocolate — a flow-wrap film, a foil wrapper, a sealed food-contact tray, or a carton that holds the chocolate directly. Direct contact is a regulatory question: it depends on the specific material, coating, liner, applicable regulations, and intended use. A box can only be described as direct food contact when the board and every applied ink and coating support it.
Secondary packaging
Secondary packaging is the outer carton, rigid box, or gift box that holds the primary layer — or that carries a pre-wrapped chocolate, a bar, or an individual chocolate that already has its own food-contact wrapper. Most of what XC Paperbox produces for chocolate is paper secondary packaging: folding cartons, rigid boxes, gift boxes, two-piece boxes, and window boxes.
The boundary that matters
Grey board, art paper, and a standard folding carton should not be assumed to be safe for direct chocolate contact. Where chocolate needs direct-contact packaging, specify an appropriate food-contact primary layer — or specify a food-contact-capable board and inks and confirm the material and specification with the supplier. Our folding cartons can be specified in SBS or CCNB board with food-grade water-based inks for food-contact applications; for rigid and gift boxes the chocolate should sit in its own food-contact layer. This guide is about the paper packaging around the chocolate, not about food preservation or shelf life.
