Custom Waterproof Bag Lining

For professional waterproof bags such as dry bags and waterproof duffel bags made with heat-sealing or high-frequency welding, we typically use an unlined construction. This helps reduce internal stitching and structural interference and improve overall waterproof performance.

If your product requires better internal organization, cushioning, stain resistance, or user comfort, we can also add different types of linings, inner layers, or functional pockets based on the intended application

Available lining and functional material options include 210D polyester, PU-coated polyester, TPU-laminated lining, PVC / PEVA, tricot / fleece, and mesh pockets.

Structural Design of Custom Waterproof Bag

Custom Waterproof Bag Structural Design

We can customize a wide range of waterproof bag structures based on different applications, capacities, and load-bearing requirements.

Common waterproof bag structures include:

Custom Waterproof Bag Zipper

Based on your waterproof performance requirements, opening and closing experience, and durability needs, we can recommend the most suitable zipper options. Available choices include YKK, SBS, standard nylon zippers, water-repellent zippers, waterproof zippers, and airtight zippers in different specifications.

In addition to the zipper itself, the zipper sliders and pull tabs can also be customized. Options include metal sliders, rubber/PVC pull tabs, cord pulls, and webbing pull tabs, with your brand logo added if required.

If you already have specific requirements for the zipper brand, color, size, or construction, we can source the components and produce samples accordingly.

Custom Hardware for Leather Bag

Custom Hardware and Buckle

We can select suitable hardware and buckles based on different product requirements, including D-rings, square rings, adjuster buckles, snap hooks, side-release buckles, magnetic buckles, rivets, eyelets, and metal logo plates.

Common hardware materials include zinc alloy, stainless steel, aluminum alloy, and iron. For waterproof bags, we prioritize corrosion resistance, strength, and long-term durability. For product with a greater focus on appearance, we can apply finishes such as gunmetal, black nickel, matte black, silver, antique brass, and gold to create a consistent overall look.

If you already have specified hardware components, we can produce samples according to your requirements.

Seam Construction and Joining Methods

We offer a variety of joining methods, including sewn construction, seam taping, adhesive bonding, welded construction, and hybrid combinations.

 

For products with more complex structures and multiple compartments, such as waterproof backpacks, laptop bags, and travel bags, we typically use sewn construction to allow for more pockets and internal organization. Waterproof seam taping can also be added to reduce the risk of water entering through needle holes.

For structures that are not suitable for traditional sewing, we can also use adhesive bonding or bonding film techniques. Professional adhesives or bonding films are used to join materials and improve seam sealing performance.

For products that require a higher level of sealing, such as dry bags, waterproof travel bags, kayak bags, fishing bags, and marine bags, we can use HF/RF welding, hot-air welding, or other suitable heat-welding processes, depending on the material. These processes fuse the waterproof-coated materials directly together to create sealed seams and achieve more consistent waterproof performance.

Quality Control and Testing for Waterproof Bags

Full-Process Quality Control

At AG Bags Factory, quality inspections are carried out throughout the entire production process, from incoming raw materials and pre-production confirmation to manufacturing, packaging, and final shipment. Any issues identified during production are addressed before the products move to the next stage.

Comprehensive Testing Capabilities

Our factory is equipped with more than 20 types of testing equipment for materials and finished products. Depending on product requirements, we can conduct zipper tests, load-bearing tests, strength tests, seam and stitching tests, drop tests, and relevant compliance testing. For waterproof performance, we carry out appropriate tests based on the fabric, bag construction, closure system, and seam-sealing method.

Flexible Inspection Standards

During mass production, products are inspected at different stages, and final shipment inspection can be carried out according to AQL 2.5. You may also arrange inspections by SGS, Intertek, BV, or other designated third-party inspection agencies, and we will fully cooperate with the inspection process.

Choose the Right Development Route

Whether you already have a complete design package or only a product concept, we can provide the right development solution for your needs, including OEM production based on your drawings, ODM product development, or private label customization based on our existing designs.

We can help you finalize details such as materials, structure, functionality, logo, colors, and packaging, reducing development time and trial-and-error costs while making the sampling and mass production process more efficient.
