Choosing a bag material is not only a production decision. It affects how the product looks, how much weight it can carry, which printing methods can be used, how compactly it can be packed, and how buyers understand the brand.
Cotton, canvas, and RPET are three frequently requested materials for custom shopping bags, promotional totes, corporate gifts, retail packaging, and private label collections. They can sometimes be used for similar products, but they create very different results.
A lightweight cotton tote may work well for an event giveaway. A heavy canvas bag may be more suitable for a premium retail collection. An RPET foldable bag may be the better choice for supermarket campaigns or travel programs where low weight and compact storage matter.
This guide compares the three materials from a practical B2B purchasing perspective.
| Factor | Cotton | Canvas | RPET |
|---|---|---|---|
| Material type | Natural textile fiber | Heavier woven cotton or blended fabric | Recycled polyester material |
| Typical appearance | Soft and natural | Structured and premium | Modern and technical |
| Weight | Light to medium | Medium to heavy | Usually light |
| Foldability | Good | Lower with heavy fabric | Excellent |
| Carrying strength | Depends on fabric weight | Usually strong | Depends on density and construction |
| Printing | Good for screen printing | Excellent for printing and embroidery | Suitable for multiple printing methods |
| Water performance | Absorbs moisture unless treated | Absorbs moisture unless treated | Can be coated for water resistance |
| Common uses | Promotions, retail, gifts | Premium retail, fashion, heavy-duty totes | Supermarkets, travel, sports, campaigns |
| Brand positioning | Natural and approachable | Durable and premium | Recycled and functional |
There is no single best material. The correct choice depends on the product structure, target buyer, intended load, expected price, visual direction, and sustainability claim.
A cotton bag is usually made from lightweight or medium-weight woven cotton fabric. It is softer and more flexible than heavy canvas and is widely used for promotional totes, retail shopping bags, event bags, gift packaging, and lifestyle merchandise.
Cotton bags are often selected because they provide a familiar textile appearance and a relatively smooth surface for logo printing.
Cotton gives bags a casual and approachable appearance that works well for:
Cotton generally supports:
Simple logos, slogans, illustrations, and campaign graphics can normally be applied clearly.
Light cotton bags can be packed flat and distributed efficiently for events, trade shows, retail campaigns, and promotional programs.
Cotton can be used for:
Cotton absorbs moisture unless it receives a special finish. Lightweight cotton may also lose shape when empty and may not be suitable for heavy products without stronger fabric, reinforced seams, or wider handles.
Cotton can shrink or change appearance after washing, so care instructions should be based on the actual fabric, dyeing, printing, and construction.
Canvas is a heavier and more tightly woven fabric commonly made from cotton or cotton blends. It is generally thicker, firmer, and more structured than standard cotton fabric.
Canvas is widely used when buyers want a reusable bag with stronger carrying performance and a more premium textile appearance.
Canvas is suitable for products that require:
Canvas bags are commonly used by:
The heavier fabric creates a more substantial hand feel than lightweight promotional cotton.
Canvas supports:
Embroidery and patches are especially effective when buyers want the bag to look like a retail product rather than a simple giveaway.
A properly constructed canvas tote can be used for shopping, work, travel, books, groceries, gifts, and daily carrying.
Canvas usually costs more and weighs more than lightweight cotton or RPET fabric. Heavy canvas also requires more carton space and may increase shipping costs.
Like cotton, untreated canvas absorbs moisture. A lining, coating, laminated interior, or waxed finish may be added where more protection is required.
RPET refers to recycled polyethylene terephthalate. In bag manufacturing, it is commonly processed into recycled polyester fibers and fabrics.
RPET fabric can be lightweight, woven, ripstop, mesh, felted, laminated, or coated. It is used across shopping bags, backpacks, cooler bags, drawstring bags, travel organizers, cosmetic bags, and outdoor products.
RPET allows brands to use recycled polyester in product development and reduce reliance on virgin polyester feedstock.
Buyers should verify:
RPET fabrics are well suited to:
The material can often be packed into a small pouch, making it useful for high-volume distribution and travel retail.
Depending on the specification, RPET fabric can offer:
RPET can be used for:
RPET does not automatically mean the entire product is recycled. A bag may still include standard zippers, virgin polyester lining, PP webbing, foam, metal hardware, or other materials.
RPET is also not automatically waterproof or biodegradable. These claims depend on the complete product structure and supporting evidence.
Material name alone does not determine strength.
Important factors include:
A heavy cotton canvas bag may be stronger than a lightweight RPET tote. A reinforced RPET Oxford bag may perform better than a thin cotton shopping bag.
Buyers should request load testing based on the intended product rather than relying only on the material description.

Best suited to:
The correct printing method depends on fabric texture, color, coating, artwork, order quantity, and required durability.
Untreated cotton and canvas absorb moisture. Buyers can add:
RPET polyester can be developed with:
However, coated fabric does not automatically make the finished bag waterproof. Seams, zippers, and openings must also be considered.
Lightweight RPET and ripstop fabrics can fold into compact pouches and are suitable for travel, supermarket, and promotional programs.
Light and medium cotton bags pack flat easily, but thicker cotton requires more space.
Heavy canvas provides better structure but increases folded thickness, carton volume, and freight cost.
For large-volume promotional orders, folded dimensions and carton quantity should be confirmed during sampling.
The final cost depends on more than the base fabric.
Important cost factors include:
In general:
Buyers should compare complete specifications rather than only the material price.
Cotton is a natural fiber, but buyers should avoid assuming that every cotton product has the same environmental profile. Farming method, dyeing, fabric weight, production, and product lifespan all matter.
Canvas describes a fabric construction, not a sustainability category. Canvas may be made from conventional cotton, organic cotton, recycled cotton, polyester blends, or other fibers.
RPET contains recycled polyester, but the recycled percentage and product-level claim must be verified.
Responsible claims should be specific, such as:
Avoid broad unsupported claims such as:
unless the complete composition and supporting documentation justify them.

Not exactly. Canvas describes a heavier woven fabric construction. It is often made from cotton but may also contain polyester or other fibers.
Strength depends on fabric weight, weave, stitching, handles, and reinforcement. Heavy canvas is often strong, but properly constructed RPET and cotton bags can also perform well.
