Choosing the right paper substrate and finishing is the foundation of stable, compliant paper boxes and paper bags. Many EU buyers focus only on visual effect and overlook load requirement, recyclability and PFAS rules.
Common paper substrates for our products Virgin kraft: high tensile strength, clean printing, ideal for heavy-duty paper bags. Easy to get FSC traceability. Recycled kraft: natural rustic look, lower carbon footprint, better for light-load retail bags. Speckles may appear on solid printing. Coated art paper: smooth surface, vibrant colour, widely used as face paper for rigid boxes. Greyboard: core board for rigid boxes, thickness selected based on product weight.
Guide to post-press finishes Water-based varnish: low VOC, recyclable-friendly, low cost, recommended for most EU orders. Foil stamping: for logo highlight, small area works better than full solid foil. Embossing / debossing: tactile effect, no extra plastic added, good for PPWR. Lamination: gloss or matte, scratch-resistant, but full plastic lamination reduces recyclability. Spot UV: raises gloss contrast, suitable for logo and graphic emphasis.
Simple matching logic Heavy load paper bag → virgin kraft + water-based varnish Light load eco brand bag → recycled kraft, minimal finishing Luxury rigid box → coated art paper + small foil / deboss Gift set with strict recyclability → avoid full plastic lamination
Compliance reminder: some barrier coatings contain PFAS. If you need water or grease resistance, choose PFAS-free aqueous barrier. We provide substrate swatches and finish samples for your selection.
