In 2B customization scenarios such as international expos, brand promotion, and supermarket gifts, canvas bags, as carriers with both practicality and communicability, their design directly affects brand exposure and user experience. Among them, large-capacity design is a core demand—visitors need to load brochures, samples, souvenirs and other items during the expo. Canvas bags with insufficient capacity are easily discarded, which directly weakens the brand communication value.
Guangdong Gahumi Textile Co., Ltd. (abbreviated as Gahumi) has been deeply engaged in textile customization for 31 years, and has a deep understanding of the design logic of international expo custom canvas bags. It has formed an exclusive plan from structure, material to detail control, becoming the first choice OEM manufacturer for many global brands' expo customization.
The design of large-capacity
custom canvas bags must adhere to the three core principles of "load-bearing compliance + reasonable space + portability balance". Many
customizers only pursue "large size" but ignore the balance between load-bearing and portability, leading to problems such as shoulder strap breakage and bag deformation during use. When receiving requirements, Gahumi's design team will first clarify the core loading needs of the expo scenario—for example, technology expos mostly have paper materials and small samples, so layered storage should be emphasized; consumer goods expos may involve trial products and other heavy objects, so the load-bearing structure needs to be strengthened. Based on this, the team will issue a
customization plan including size parameters, load-bearing test data, and storage partitions to avoid design blind spots from the source.
Scientific structural design is the key to achieving large capacity. Gahumi commonly uses a combined design of "main bag expansion + layered storage". The main bag adopts a three-dimensional cutting process, which increases the storage space by 30% compared with flat cutting under the same fabric consumption. At the same time, the bag mouth adopts a double design of drawstring and snap button, which not only ensures large capacity but also prevents items from falling. To meet the needs of classifying expo materials, 2-3 inner bags of different sizes will be added inside the main bag for placing mobile phones, business cards and other small items; in some high-end customization needs, a detachable side bag will also be matched to meet the separate storage of kettles, umbrellas and other items. In a customization project for an international electronics expo in Europe, this design allowed a 42cm×35cm×15cm custom canvas bag to successfully hold 10 thick brochures, a small sample machine and personal items, with no obvious marks on the shoulder straps.
Material selection and process treatment determine the durability of large-capacity custom canvas bags. Gahumi's raw material center strictly screens canvas bag fabrics, usually using 8oz-16oz pure cotton canvas. This kind of fabric has high density and strong stretch resistance. After pre-shrinking and shaping treatment, it can bear more than 10kg weight without deformation. For brand customization needs that require long-term reuse, "canvas + Oxford cloth composite" material will be used to enhance wear resistance. In terms of craftsmanship, the connection between the shoulder strap and the bag body is treated with "three-thread sewing + reinforced rivets", and the joint strength is increased by 50% compared with ordinary sewing; the bag bottom adopts a diamond-shaped double sewing process to disperse the pressure of heavy objects on the bag bottom.
These detailed treatments ensured that the custom canvas bags customized by Gahumi remained intact after 8 hours of daily load-bearing use at the Ghana Economic and Trade Expo in Africa, winning repeat orders from the participating brands.
As an OEM/ODM manufacturer integrating production, design and service, Gahumi can provide customizers with full-chain services. The 3 production bases with a total area of 5,000 square meters are equipped with a fully automatic printing center and a sewing center, which can realize integrated production from fabric cutting, printing to sewing.
More than 300 professional employees can be flexibly deployed to efficiently meet the needs from small orders of 1,000 pieces to million-level bulk custom canvas bag orders. Whether it is a simple large-capacity custom canvas bag for supermarket gift customization or a creative layered custom canvas bag for coffee chain peripherals, Gahumi can combine brand tone to perfectly integrate large-capacity design with brand elements, making the canvas bag a mobile brand promotion carrier.
At present, the
international expo large capacity canvas bags customized by Gahumi have been exported to regions such as the United States, Europe, and the Middle East, serving many large-scale official expos and brand events.

Q: What is the customization quantity range of international expo custom canvas bags that Gahumi can undertake?
A: We support small-batch trial orders starting from 500 pieces, and can also undertake million-level bulk orders. Relying on multi-line production resources, small batches can be delivered within 7 days, and large batches can be completed within 15-20 days.
Q: Can the design plan of large-capacity custom canvas bags be modified according to brand needs?
A: Yes. The professional design team can adjust the size, storage structure, printing position, etc. according to the brand VI and expo scenario, and provide more than 3 design drafts for selection until a satisfactory plan is confirmed.
Q: What links are included in the OEM service process of canvas bag customization?
A: The process is: demand communication (capacity, material, style, quantity) → design plan + quotation → sample making and confirmation → contract signing and advance payment → mass production → multiple quality controls → customer acceptance → logistics and distribution.
Q: Besides large-capacity custom canvas bags, can other expo-related textile products be customized?
A: Yes. We can customize expo promotional custom T-shirts, custom brand scarves, custom caps and other products simultaneously, supporting multi-category combined customization to achieve a unified style of expo peripheral products.
Q: How to ensure that the load-bearing of bulk customized canvas bags is consistent with the samples?
A: Adopt the mechanism of "pre-production material inspection + sampling test during production + full inspection of finished products". Each finished product must pass a tensile test of 1.2 times the rated load-bearing to ensure that the bulk products are consistent with the sample quality.
