How to Choose the Right Material for Custom Bags
The main material families
Cotton runs from light single-layer fabric for promotional totes to medium weights with gussets and reinforced handles for retail. Canvas is the heavier, structured end: it holds shape, feels substantial, and takes print well. Polyester is lightweight, tear-resistant and easy to decorate, which makes it the basis for drawstring bags, backpacks and many pouches; woven polyester is more durable than non-woven. Non-woven polypropylene is cheap, printable and light, common in promotional and grocery-style bags. Recycled RPET, made from PET bottles, gives a recycled-content option with a look close to standard polyester.
Material decision guide
| Material | Typical GSM range | Best used for | Durability | Relative cost |
|---|---|---|---|---|
| Light cotton | ~100-140 gsm | giveaways, high volume | low-medium | low |
| Medium cotton | ~160-280 gsm | retail totes, reuse | medium-high | medium |
| Heavy canvas | ~300-350 gsm | beach, structured retail | high | medium-high |
| Woven polyester | varies by denier | backpacks, drawstring, pouches | medium-high | low-medium |
| Non-woven PP | ~80-120 gsm | low-cost promo, grocery | low-medium | lowest |
| Recycled RPET | varies | recycled-content lines | medium | medium |
GSM ranges above are general industry references; confirm exact weights offered for your product with the manufacturer.
What affects the price
Fibre and weight set the base. Construction (gusset, reinforced base, lining) and hardware add to it. Decoration method and colour count matter, and so does whether the fabric suits that method: an all-over photographic print needs laminated cotton or sublimation-ready fabric, not raw canvas. Quantity spreads setup cost.
What buyers should prepare before requesting a quote
- The use case in one line (giveaway, retail, reuse, technical carry)
- A target weight or GSM range, or a reference product
- Required durability and load
- Any recycled-content or certification requirement, marked as a requirement so it is verified
- Decoration method, so fabric and print are chosen together
Common mistakes to avoid
Choosing a fibre by name and ignoring weight. Specifying heavy canvas for a budget giveaway, or thin cotton for a bag meant to be reused for years. Assuming "non-woven" and "woven" polyester perform the same. Treating "sustainable" as a blanket label: only genuinely recycled or certified material should carry that claim, and certifications should be confirmed with documentation.
Material decision guide for branding
Decoration follows the fabric. Screen print and digital print suit cotton, canvas and polyester. Sublimation needs laminated or sublimation-ready fabric. Embroidery suits heavier cotton, canvas and waffle fabric. Decide both together so the artwork you want is achievable on the fabric you pick.

Buyer checklist
- Use case (giveaway, retail, reuse, technical carry) determines the material family.
- Weight (GSM) affects durability as much as the fibre itself.
- Decoration method must suit the fabric (e.g. sublimation needs laminated fabric).
- Construction (gussets, lining, padding) adds cost beyond the base material.
- Only state recycled-content claims you can back with documentation.
RFQ / spec checklist
- Use case in one line (giveaway, retail, reuse, technical carry)
- Target weight or GSM range, or a reference product
- Required durability and load expectation
- Any recycled-content or certification requirement
- Decoration method, so fabric and print are chosen together
Frequently asked questions
What GSM should a cotton tote be?
It depends on the use. Light cotton around 100-140 gsm suits giveaways; retail and reusable totes usually use heavier cotton or canvas. Confirm available weights with the manufacturer.
Is recycled RPET as durable as normal polyester?
In general use it performs similarly for most bag applications. Durability still depends on weight and construction, so specify both.
Which material is cheapest?
Non-woven PP is usually the lowest unit cost, which is why it is common for large promotional runs. Cost also depends on size, construction and decoration.
Can I get an all-over print on canvas?
Full-coverage photographic prints need sublimation-ready or laminated fabric. Raw canvas suits screen and digital logo printing rather than edge-to-edge artwork.
How do I claim a bag is sustainable?
Only on the basis of genuinely recycled material or a held certification, with documentation. Avoid blanket sustainability claims that cannot be supported.
