Packaging Materials Library
Most packaging problems traced back to a bad material choice rather than a bad print, and most material choices can be made correctly from three facts: weight, surface, and environment.
At a glance
- Greyboard cores 1.0-3.0 mm
- Printed art-paper wraps from 120-170 gsm
- Specialty, linen and textured wraps
- Recycled-content core options
Overview
Most packaging problems traced back to a bad material choice rather than a bad print, and most material choices can be made correctly from three facts: weight, surface, and environment. This library is how our engineers talk about those facts with buyers before a board grade is written into a quotation.
Buyers in North America, Europe, the Middle East, Australia, New Zealand and Brazil rely on this because it removes ambiguity at the quotation stage.
Rigid Box Substrates
Rigid boxes are built from a greyboard core wrapped in printed or specialty paper; core thickness sets the perceived weight and crush resistance. Typical cores run from 1.0 mm to 3.0 mm, with the wrap chosen separately for print fidelity or texture.
- Greyboard cores 1.0-3.0 mm
- Printed art-paper wraps from 120-170 gsm
- Specialty, linen and textured wraps
- Recycled-content core options
All of this is confirmed in writing before a deposit is requested.
Folding Carton and Bag Stocks
Folding cartons use coated or uncoated board in the 250-400 gsm range, chosen for crease behaviour as much as print quality. Carrier bags use kraft or art paper from 120-250 gsm with reinforced handles and a compatible handle attachment.
- C1S and C2S coated board 250-400 gsm
- Natural, white and recycled kraft 120-250 gsm
- Grease-resistant and food-safe options
- Handle, eyelet and reinforcement specifications
Our export desk can expand any point here into a written specification for your project.
Choosing by Use Case
A heavy glass jar needs a denser core and a reinforced base; a lightweight apparel set can use a thinner board and a flat-pack structure. Humid shipping routes and long warehouse storage favour coated stocks and moisture-controlled packing.
- Match board to product weight and drop risk
- Account for humidity on sea freight routes
- Consider recyclability and mono-material goals
- Confirm food-contact barriers where relevant

Frequently Asked Questions
- What grammage should I choose for a rigid box?
- It depends on product weight and box size; send both and we will recommend a core thickness and wrap.
- Is kraft suitable for luxury packaging?
- Yes, with the right print treatment and a debossed or foil logo it is a common premium choice.
- Can I get FSC-certified material?
- Yes, subject to mill availability and stated at quotation.
