Frequently Asked Questions About Packaging Terms
Quick clarification for common buyer and design questions.
What does GSM mean in packaging? +
GSM means grams per square meter. It’s a standard measure of paper weight that helps buyers estimate thickness, stiffness and perceived quality.
What is the difference between FSC and recycled paper? +
FSC focuses on responsible forest management and chain-of-custody certification. Recycled paper describes fiber content (post-consumer or pre-consumer). Many projects use both.
What is a dieline in packaging design? +
A dieline is a technical template showing cut lines, fold lines, bleed and safe areas—used to ensure your artwork fits the packaging structure in production.
Which printing method is best for premium packaging? +
Offset printing is often best for premium packaging with consistent color and high-volume needs. Digital printing can be ideal for small runs, prototypes, or personalization.
What is the difference between rigid boxes and folding cartons? +
Rigid boxes use thick board (often greyboard) and are pre-formed for luxury presentation. Folding cartons ship flat and are more cost-efficient for many retail applications.
How do packaging suppliers determine MOQ? +
MOQ depends on materials, printing method, finishing processes, tooling, and production efficiency. Suppliers calculate MOQ to balance setup cost and unit price.
