OEM & ODM Custom Process for PVC Bags & Fabric Bags | Complete Guide
For global brand owners and wholesale buyers, customized bag products are the core way to build product differentiation and improve market competitiveness. Generic universal styles can only participate in low-price competition, while exclusive customized products can form brand characteristics, increase product added value and obtain higher profit margins. Lvfeng Packaging provides one-stop OEM and ODM custom services covering all our product lines, including PVC packaging bags, waterproof dry bags, swimming bags, walkie-talkie waterproof pouches, bucket bags, kids school bags, outdoor backpacks and insulated lunch bags, helping customers create exclusive market hot-selling products.
Our complete custom process is standardized, transparent and efficient, which can effectively save customers’ time cost and communication cost. The first step is demand communication and scheme confirmation. Customers can provide design sketches, reference pictures, size parameters, target materials, printing requirements and market usage scenarios. Our professional technical team will evaluate product feasibility, optimize structure and technology according to customer budget and market standards, and put forward professional improvement suggestions to avoid potential quality risks in advance.
The second step is material selection and sample confirmation. For PVC series products, we provide transparent, frosted, colored, thickened and environmental-friendly food-grade PVC materials with different thickness options. For fabric bags, we match waterproof Oxford cloth, thickened canvas, breathable sponge and food-grade thermal insulation lining according to product positioning. After material confirmation, we will produce pre-production physical samples, adjust size, structure, printing position and color effect according to customer feedback until the sample is 100% confirmed.
The third step is mass production and process quality control. After sample approval, we arrange raw material procurement, cutting, molding, printing, welding or sewing, assembly and fine processing. During mass production, our QC team conducts random inspection for multiple times to check flatness, sealing performance, stitching firmness and printing fastness, ensuring that all bulk goods are consistent with the confirmed samples.
The fourth step is finished product inspection and export packaging. Before delivery, all products will pass full inspection, eliminate defective products, and conduct professional export packaging, customized carton marks and labels according to customer requirements to meet international shipping standards.
We support diversified custom needs, including brand logo customization, appearance color customization, structural function customization and exclusive new style ODM development. Whether it is small-batch trial customization for new brands or large-batch long-term customized orders for mature enterprises, we can provide matching solutions. With mature foreign trade experience, we are familiar with international environmental protection standards and export procedures, providing stable and reliable customized products for global customers.
