Why waterproof backpacks are more expensive than regular backpacks

 

With the progress of science and technology, the common products in people's lives are constantly updated and iterated, and the price has also risen a lot. Take the most common backpack, nowadays more and more people are used to using a waterproof backpack, the price is much more expensive than ordinary backpacks. However, have you ever wondered why waterproof backpacks are often more expensive than ordinary everyday backpacks? In fact, behind this, there are a lot of technology and fabric upgrades, which is not just a waterproof coating on the surface of the backpack. Professional waterproof backpacks are designed to provide weatherproof protection, which also involves the difference in materials, zipper design and air tightness design. Waterproof backpacks are a popular choice for outdoor enthusiasts, travelers, and commuters, and in this article, we'll explore the key factors that make them more expensive and why investing in them is worth it.

 

 

The difference between waterproof backpack and ordinary backpack

Waterproof backpacks and regular backpacks may look similar on the surface, but their structure and function are very different. Below we will introduce the main differences from the materials used in the backpack, production technology, design characteristics and other aspects in detail:

 

 

Materials: Ordinary backpacks are usually made of fabrics such as polyester or canvas, these fabrics have basic durability, but the water resistance is very poor, some ordinary backpacks said that their backpacks can be waterproof, in fact, they are only in the backpack to show some waterproof coating, can only be slightly waterproof, such as splashing and other short time contact with water. In contrast, waterproof backpacks usually use advanced materials such as TPU (thermoplastic polyurethane), PVC (polyvinyl chloride) or coated nylon, which has excellent water resistance, and other waterproof technologies can realize that the backpack can be soaked in water for a long time without getting wet. And these materials are usually high-density materials with excellent tear resistance and are very durable and strong even under extreme conditions. Due to the excellent performance of these materials, the relative cost will be higher, resulting in a higher price of waterproof bags.

 

Manufacturing technique: Regular backpacks are typically stitched with standard seams, which make the seams susceptible to water seepage and tear. However, waterproof backpacks often use advanced stitching methods such as thermal welding, seamless bonding and high-frequency welding, which ensure extremely high air tightness and ensure that no water will penetrate into the joint. At the same time, these complex technologies require specialized machines and professional technicians to operate, resulting in higher production costs.

For example, the principle of high-frequency welds (HF) is to use high-frequency electromagnetic fields to make the contact surface molecules of plastic materials (such as PVC, TPU, etc.) vibrate to generate heat, melt quickly and combine under pressure to form a solid seamless welding. The main equipment used includes high-frequency welding machines (which generate electromagnetic fields for heating), molds (which control the shape of the weld), air pressure systems (which apply pressure), cooling systems (which solidify the weld), and control panels (which regulate welding parameters). The cost of this technology is relatively high, and the cost is higher than that of RF welding joints. But it can also bring more efficient waterproof effect.

 

Design features: Waterproof backpack is usually used in the sealing design of the roll top seal, waterproof zipper and sealing layer and other special design, can maximize the waterproof effect. Regular backpacks may have a basic zipper and an open compartment, which makes them almost impossible to contact water for long periods of time without risking water.

 

 

Why is a waterproof backpack more expensive

After understanding the difference between the waterproof bag and the ordinary backpack mentioned above, I believe we can probably understand why the waterproof backpack will be more expensive, then let us in-depth understand the specific reasons for the higher price of the waterproof backpack in many aspects:

 

 

 

 

• Quality materials: Waterproof backpacks are made of high-density materials such as TPU and coated nylon for excellent water resistance, durability and environmental adaptability. These materials are much more expensive than the basic fabrics used in ordinary backpacks. FLW's Medium Waterproof Backpack, for example, uses seamless welding technology, ultra-lightweight TPU waterproof and tear resistant material, with a thoughtfully designed waterproof zipper, and the elastic band compressions into a double seal when pulled to ensure lasting waterproof protection.

 

• Professional manufacturing process: The production of waterproof backpacks involves professional technologies such as heat sealing and seamless welding. These processes require advanced machinery and skilled technicians, which increases manufacturing costs. Unlike ordinary bags, which can be mass-produced using standard sewing techniques, waterproof bags require precision and attention to detail. FLW has a unique air tightness patent and can produce waterproof backpacks with high air tightness. HF and RF weld technologies are used.

 

• Durability: The waterproof backpack is made of high-density materials that can withstand most of the harsh conditions outdoors, whether it's sudden downpours, dusty trails or muddy campsites. Long service life means you don't need to replace it as often.

 

• Testing and quality checks: In order to earn the "waterproof" label, these backpacks undergo rigorous testing, including immersion and stress testing. This level of quality assurance adds to the total cost, ensuring that when you buy a waterproof backpack you are investing in something that truly performs well.

 

• Research and development: Different companies will invest a lot of money in the development of waterproof technology for waterproof backpacks, and different brands have their own waterproof technology patents. Brands often experiment with different coatings, material blends and construction techniques to enhance water resistance without constantly reducing the weight of the backpack and improving other essential qualities such as comfort. These innovations come at a high cost, which is reflected in the final price of the product. For ordinary backpacks, it seems that the brand only needs to consider the appearance of the design is enough.

 

• Limited production: Expensive materials and complex production techniques and processes mean that many waterproof backpacks are produced in smaller quantities than ordinary backpacks. This limited production helps maintain quality, but also increases costs due to a lack of economies of scale.

 

• Certification and compliance: Waterproof backpacks often meet specific industry standards and certifications, such as IP ratings (intrusion protection) that indicate water resistance. Obtaining and maintaining these certifications requires regular testing and compliance checks, which can increase overall costs.

 

 

Why do you need to buy a waterproof backpack

Although the waterproof backpack price is higher, but if you have the following needs, it is recommended that you can consider buying one:

 

 

 

Protect valuables: Whether it's a laptop, camera or personal belongings, a waterproof backpack ensures your belongings stay dry and safe, even in wet weather conditions outdoors. This level of protection is unmatched by an ordinary backpack.

Waterproof backpacks are ideal for a variety of activities, including hiking, biking, traveling, and daily commuting. Their versatile design means you can achieve multiple uses with just one package.

 

Enhanced comfort and durability: Many waterproof backpacks are often designed for outdoor adventure sports, so to reduce the burden of travel, ergonomic design, such as padded shoulder straps, breathable backboards and weight distribution systems, make carrying heavy loads more comfortable.

 

Less need to replace: While the cost of purchase may be higher, the durability and functionality of a waterproof backpack can save you money in the long run because you won't need to replace your backpack as often.

 

 

How to choose the right waterproof backpack

If after reading the above, you can't wait to buy a waterproof backpack, but don't worry, given the many options available, choosing the right waterproof backpack can be overwhelming. Here are some shopping guides:

 

 

• Consider the use: Please choose according to the scenarios you mainly want to use. Because of different scenarios, the functions designed by businesses for waterproof backpacks may not be the same. Before purchasing, please communicate your main application scenarios to the merchant.
• Check the waterproof rating of the waterproof backpack: Look for a backpack with a high IP rating (such as IPX6 or IPX7), which indicates excellent water resistance. Knowing these grades will help you choose a backpack that meets your needs.
• Check materials: Choose backpacks made of TPU(Thermoplastic polyurethane), coated nylon, or other advanced waterproof materials. These are not only water resistant, but also increase the durability of the bag. But pay attention to understand the outer lining and the inner lining of the material
• Pay attention to seams and closures: Make sure the bag has heat-sealed seams and waterproof zipper or roll top closures, as these features are essential for water resistance.
• Design for overall comfort: If you are going to be carrying for a long period of time, it is recommended that the selection of adjustable shoulder straps, padded rear panel and proper weight distribution are essential for long-distance walking comfort, especially if you are carrying heavy loads.
