In the field of custom packaging, paper is the first material encountered, and GSM (grams / square meter) is a key indicator defining paper weight and thickness. Therefore, understanding GSM helps in selecting durable and cost-effective packaging.
Common GSM ranges and applications:
Low GSM (80-120 GSM): Lightweight paper, suitable for making instruction manuals, brochures, or inserts.
Medium GSM (150-250 GSM): Strong yet easy to fold, suitable for everyday packaging, hang tags, and paper bags.
High GSM (300-400+ GSM): Stiff and rigid, often used for high-end rigid boxes and shipping cartons.
Higher GSM usually means better tear resistance and a superior feel, but it also means increased cost and potential resource waste. Therefore, choosing an appropriate GSM ensures packaging strength while avoiding excessive waste.
In custom packaging projects, GSM needs to be considered in conjunction with other factors, such as material type and surface treatment. Mastering GSM knowledge enables you to communicate effectively with manufacturers, avoid high costs associated with mistakes, and create packaging products that perform exceptionally well in the global market.

FAQ
What does GSM mean in custom packaging?
GSM stands for "grams per square meter" and measures paper density and thickness. A higher GSM indicates thicker, sturdier paper, while lower GSM means lighter, more flexible material.
Does higher GSM always mean better packaging?
Not necessarily. Higher GSM offers durability and premium feel but increases cost and material use.
Can GSM affect printing quality or finishing processes?
Yes. Thicker paper (high GSM) holds embossing and foil stamping better but may require adjusted printer settings. Lower GSM papers are easier to fold but may limit some finishing options.
