Frequently Asked Questions
What does "reverse tuck" mean on a folding carton?Reverse tuck means the top and bottom closure flaps tuck in opposite directions. The top flap tucks into the carton from the front panel, while the bottom flap tucks in from the back panel. This creates a secure pye-lock closure and keeps the printed front panel facing forward on a retail shelf. Do reverse tuck cartons need glue or tape?No. The pye-lock tuck design holds the carton closed securely without adhesive. You can add a security seal sticker or tamper-evident tape for extra protection if needed. What does .024 fibreboard mean?.024 fibreboard refers to the paperboard thickness — 0.024 inches, roughly 24 point or 610 microns. This is a standard lightweight carton thickness suitable for small products up to about 1 lb. Can you print your logo on kraft and white folding cartons?Yes. Both kraft and white cartons accept printing. White cartons are ideal for full-color printing, while kraft works best with 1-2 color designs. Custom printing typically requires a minimum order of 1,000-5,000+ units — contact us for a quote. Are folding cartons recyclable?Yes. Paperboard folding cartons are 100% recyclable and biodegradable. They are made from sustainably sourced fibers and can be recycled with other paper products. What is the PPP-B-566 federal specification?PPP-B-566 is a federal standard for folding boxes used in government packaging. It specifies requirements for bursting strength, tear resistance, and overall quality. Our reverse tuck cartons meet or exceed this spec. How do you choose the right folding carton size?Measure your product's length, width, and height, then add 1/8" to 1/4" of clearance on each side so the item slides in easily. Extra space can be filled with tissue paper or inserts for a premium look, and ordering samples first is the reliable way to verify fit before a bulk order. How to Choose the Right Folding Carton Size
