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.
