Complete Guide to Choosing Raw and Auxiliary Materials for Backpack and Bag Manufacturing

Choosing raw and auxiliary materials for backpack and bag manufacturing determines the quality and value of the final product. May Hop Phat, through practical experience, helps manufacturers, workshop owners, and handmade makers thoroughly understand canvas fabric, polyester, high-quality zippers, and standard accessories. From selecting appropriate materials to finding reputable custom backpack suppliers, this guide makes everything easier.

I. Types of Fabrics Used in Backpack and Bag Production

1. Polyester and Nylon Fabrics

Polyester fabric is one of the most popular materials when discussing raw and auxiliary materials for backpack and bag manufacturing. They stand out with high durability, good wrinkle resistance, and reasonable prices. At May Hop Phat, we commonly use Polyester 600D, 1000D, and 1680D for different products to manufacture custom backpacks in small or large quantities.

Polyester 600D is a balanced choice between durability and weight, suitable for everyday products. Meanwhile, Polyester 1000D and 1680D provide superior durability for heavy-duty products.

Nylon fabric is also an excellent choice with properties lighter than polyester but still ensuring high durability. Especially, Nylon Ripstop with its special reinforced structure helps prevent tear propagation, making it the ideal material for travel and mountain climbing backpacks.

2. Canvas and Cotton Fabrics

Canvas fabric brings classic and luxurious beauty to backpacks and bags. Traditional canvas is made from cotton, while modern canvas often combines with polyester to increase durability and reduce costs.

We favor cotton canvas fabric for its environmental friendliness and natural feeling it brings. However, cotton fabric needs thorough waterproof treatment to increase durability in wet conditions.

Waterproofing treatment techniques for cotton fabric include:

• Natural wax impregnation
• PU (Polyurethane) coating
• Silicone treatment

3. Oxford and Parachute Fabrics

Oxford fabric is one of the most popular backpack manufacturing auxiliary materials currently. They are classified by thickness such as 210D, 420D, 600D. Oxford fabric stands out with a slightly glossy surface, high durability, and good waterproof capability after PU coating.

Parachute fabric with ultra-light characteristics and excellent water resistance is the top choice for foldable backpacks and jackets. Here, we often use parachute fabric for small details or specialized backpacks for outdoor activities.

4. Premium Specialized Fabrics

Cordura is a famous premium fabric brand with superior durability, many times greater than regular nylon and polyester. This is premium raw and auxiliary materials for backpack and bag manufacturing, commonly used in professional products.

Microfiber fabric brings soft and luxurious feeling, suitable for premium bags. Meanwhile, anti-theft cutting fabric is reinforced with thin steel mesh inside, creating safe backpack products for users who frequently move in crowded places.

II. Auxiliary Materials and Accessories in Backpack and Bag Production

1. Zippers and Opening Systems

Zippers are one of the most important backpack manufacturing accessories. Zipper quality directly affects product lifespan and user experience. At May Hop Phat, we prioritize using high-quality zippers with durability and smooth operation.

Zippers are divided into several types:

• Metal zippers: Durable, luxurious but heavy and may rust
• Plastic zippers: Light, rust-free, suitable for everyday products
• Waterproof zippers: Coated with waterproof layer, ideal for waterproof backpacks

Besides zippers, other backpack manufacturing accessories like magnetic locks and snap locks also play important roles in creating good user experience.

2. Straps, Carrying Straps, and Handles

Straps made from polyester, nylon, or PP (polypropylene) are indispensable components in raw and auxiliary materials for backpack and bag manufacturing. Straps need high tensile strength and should not stretch after usage time.

Ergonomic carrying straps are designed according to ergonomics, helping reduce pressure on users’ shoulders and backs. They are usually padded with foam and covered with breathable mesh fabric to increase comfort.

Handles need to be designed firmly and comfortably when held. At May Hop Phat, we often use rubber or EVA-wrapped handles to create soft feeling and good grip.

3. Lining Layers and Padding

Lining made of polyester or nylon not only creates aesthetics inside backpacks and bags but also protects internal contents. High-quality lining will not fade or tear after usage time.

EVA foam (Ethylene Vinyl Acetate) and EPE (Expanded Polyethylene) are important backpack manufacturing auxiliary materials, creating protective compartments for laptops or electronic devices. EVA is harder and shapes better, while EPE is softer and more flexible.

Breathable mesh fabric is commonly used for parts in contact with back and shoulders, helping increase comfort and reduce sweat accumulation when using backpacks for long periods.

III. Criteria for Selecting High-Quality Raw and Auxiliary Materials

1. Durability and Load-Bearing Capacity

When selecting raw and auxiliary materials for backpack and bag manufacturing, durability is the top important factor. You can check fabric durability by simple methods such as:

• Check thickness: Thicker fabric is usually more durable, but consider the overall product weight
• Test stretch: Pull fabric in multiple directions to assess elasticity and load-bearing capacity
• Check abrasion resistance: Rub fabric sample on rough surface to assess abrasion resistance

We apply different durability standards for each product type. Laptop backpacks require higher durability than fashion bags, while travel backpacks need superior load-bearing capacity.

2. Water Resistance and Stain Resistance

Backpack and bag manufacturing fabric needs good water resistance, especially for products used daily. Modern waterproofing treatment technologies include:

• PU (Polyurethane) coating: Most common, provides basic water resistance
• Silicone coating: More premium, more durable and better water resistance
• DWR (Durable Water Repellent) technology: Creates nanoscopic coating helping water slide off fabric surface

You can test water resistance at home by dropping a few water drops on fabric surface. If water forms beads on surface instead of soaking in, the fabric has good water resistance.

3. Aesthetics and Color Diversity

2025 color trend for raw and auxiliary materials for backpack and bag manufacturing is moving toward:

• Natural and neutral tones
• Gentle pastel colors
• Neon colors for sporty style
• Modern camo and tie-dye patterns

Dyeing technique and color fastness are quality-determining factors of fabric. High-quality fabric will not fade after washing or direct sunlight exposure.

We carefully consider the combination of colors and materials to create products that are both aesthetic and durable.
