GSM paper weight guide for packaging
GSMJun 22, 20266 min read
A packaging buyer's guide to matching gsm paper weight with labels, box wraps, cards, shopping bags, inserts and premium packaging structures.
In briefGSM should be selected by structure and converting route: labels, box wraps, shopping bags, cards and inserts each need different weight, stiffness, folding and finishing tests.
01Labels need surface and application first
Wine and premium labels often start from application environment, adhesive, wet handling, print route and finishing before the final gsm is confirmed.
02Box wraps need folding behavior
Gift-box and cosmetics-box wrapping papers need stable color, controlled cracking, clean folding and compatibility with glue, foil, debossing or UV.
03Cards need presence and edge quality
Premium cards, invitations and brand stationery often use heavier stock or duplex structures, but cutting, edge quality and print method still matter.
04Bags need load and crease planning
Shopping bags need enough stiffness for brand presence while staying workable in folding, creasing, handle reinforcement and load testing.
Frequently Asked Questions
What does gsm mean?
GSM means grams per square meter. It describes paper weight, but not the whole performance of a packaging structure.
Is higher gsm always better?
No. Higher gsm can add presence, but it can also affect folding, cracking, printing, cost and converting speed.
What gsm is common for premium cards?
Premium cards often use 350-600gsm directions or duplex structures, depending on print and finishing.
What gsm is common for box wrapping?
Box wrap directions often start around 120-157gsm, while final selection depends on box structure and converting.
What should be confirmed besides gsm?
Confirm paper surface, color, stiffness, folding, print process, finishing, adhesive, certificate scope and physical sample.
