In the marketing and operation scenarios of supermarkets, custom shopping bags have long gone beyond the simple attribute of carrying tools and become a core carrier for conveying brand images, strengthening consumer memory, and practicing environmental protection concepts. As a key link in the "visual expression" of shopping bags, the printing process directly determines the presentation effect and communication intensity of brand logos, promotional information, and environmental slogans. Choosing the right printing process can allow shopping bags to accurately convey core information in massive circulation; choosing the wrong one may lead to blurry patterns, insufficient wear resistance and other problems, affecting the brand image. Guangdong Gahumi Textile Co., Ltd. (referred to as "Gahumi") has been deeply engaged in textile OEM/ODM customization for 31 years, and has become a designated customization partner for many chain supermarkets around the world with its full-chain capabilities of "process adapting to scenarios + quality guaranteeing circulation + batch efficient delivery".
The accurate selection of printing processes first depends on grasping the core needs of supermarket custom shopping bags. The customization needs of supermarket shopping bags present the characteristics of "large batches, complex scenarios, and wide circulation"—the single-batch customization volume often reaches more than 100,000 pieces, which needs to adapt to multiple scenarios such as promotional activities, member gifts, and daily shopping, and must withstand wear and tear from repeated use and handling. Gahumi's 3 production bases with a total area of 5,000 square meters have built a full-process technology guarantee system. The raw material center stores various substrates suitable for different printing processes such as canvas, non-woven fabric, and kraft paper; the printing center is equipped with 20 professional printing equipment, covering all process types such as offset printing, screen printing, and digital printing; the quality control center has a special printing fastness testing link to ensure that the process effect adapts to the circulation scenario. Among more than 300 professional teams, 40 are technicians focusing on printing process and substrate adaptation, who can accurately match the optimal process plan according to the supermarket's batch, budget, and pattern requirements.
Based on 31 years of industry experience, Gahumi has established a "demand-substrate-process" three-dimensional adaptation model to provide clear printing process selection guidelines for supermarket custom shopping bags:
- For large-batch daily shopping bags (such as more than 100,000 non-woven custom printed shopping bags in a single batch), offset printing is preferred. This process has a fast printing speed, which can complete 8,000 pieces per hour, and has uniform colors and controllable costs, suitable for simple patterns such as supermarket logos and basic promotional information. When Gahumi customized 500,000 daily shopping bags for a chain supermarket in Africa, it used offset printing with environmentally friendly water-based ink, completed delivery in 10 days, and the pattern wear resistance reached 500 rubs without fading;
- For medium-batch promotional shopping bags (such as 30,000 - 100,000 canvas custom printed shopping bags), screen printing is recommended. This process has a thick ink layer and strong three-dimensional effect, which can accurately present patterns on rough substrates, suitable for scenarios that require visual impact such as holiday promotions and theme activities. A supermarket in the United States customized 80,000 canvas shopping bags during the Christmas promotion season, and presented Christmas theme illustrations through screen printing, which had high color saturation and became a popular carrier during the promotion period;
- For small-batch high-end custom gift bags (such as member-exclusive, organic food supporting), digital printing is selected. This process has a pattern reproduction rate of 98%, supports gradient colors and fine texture printing, and is suitable for high-end and personalized customization needs. An organic supermarket in Europe customized 20,000 member-exclusive shopping bags, and presented organic farm illustrations through digital printing with clear details, enhancing the member experience;
- For high-end logo printing (such as high-brightness presentation of brand logos), gold/silver stamping can be matched to add a metallic texture on the basis of offset printing or screen printing, strengthening brand recognition.
Quality assurance for process implementation is the core support for the circulation value of supermarket custom shopping bags. Gahumi controls printing quality from the entire process of "substrate pretreatment-process execution-finished product inspection": before substrate storage, flatness and ink absorption are tested to avoid missing printing and smudges during printing; an intelligent alignment system is used during printing to ensure that the position deviation of logos and texts does not exceed 0.5mm; during the finished product stage, rub fastness test (500 dry rubs, 300 wet rubs without fading) and folding resistance test (200 repeated folds without pattern cracking) are carried out to ensure that shopping bags maintain a good visual effect in the high-traffic circulation scenario of supermarkets. At the same time, in response to the common "multi-material, multi-process combination" needs of supermarkets, such as offset printing on the main body of non-woven custom shopping bags + gold stamping on logos, Gahumi has established process connection standards to ensure natural transition between different processes and unified quality.
Rich global supermarket
customization cases confirm Gahumi's adaptability to printing processes. A large chain supermarket in the Middle East customized 600,000 recycled cotton
custom shopping bags to promote its "environmental protection upgrade" strategy, requiring
custom environmental protection logos and promotional slogans to be printed, and 3 store sizes to be distinguished, with a delivery cycle of 15 days. The difficulties of this order were "large batch + multi-size + environmental ink requirements". Gahumi locked in recycled cotton substrates in advance through the raw material center and completed pretreatment. The printing end adopted the process of "offset printing as the main + local gold stamping on logos", and launched three-line parallel production, with each production line corresponding to one size. At the same time, a sampling inspection mechanism every 2 hours was established, and finally delivery was completed 1 day in advance. The products were recognized by consumers for "clear printing + wear resistance and durability", and the supermarket subsequently handed over all annual
shopping bag customization orders to Gahumi.
In addition to core printing process services, Gahumi also provides "integrated
customization solutions for supermarket peripherals", which can customize supporting products such as
custom shopping bags,
promotional custom T-shirts,
custom employee aprons, and
custom promotional flags at the same time to ensure unified printing style and brand vision; supports
private label customization, printing exclusive supermarket logos on
shopping bag wash labels and handles; provides zoned packaging services, packaging by store and size to simplify the supermarket distribution process. An exclusive project team follows up the order throughout the process, synchronizing progress in real time from process selection, design proofing to production and delivery, making the supermarket procurement process transparent and controllable.
Since its establishment in 1994, Gahumi has always focused on the core logic of "process accurately adapting to scenario needs", and built core competitiveness with production capacity, quality and efficiency. For 2B business personnel such as supermarket purchasers, choosing Gahumi is not only choosing a
Shopping Bag Printing Supplier and
Supermarket Shopping Bag OEM, but also a partner who can deeply understand printing needs and use professional processes to enhance brand communication effects. For more printing process plans and service details, please visit the
