As environmental awareness increases, more and more brands and consumers are paying attention to the application of sustainable materials to reduce the burden on the environment. Recycled Polyurethane (Recycled PU) is one of the eco-friendly materials that has attracted widespread attention, especially in the backpack industry, where more and more companies and designers are choosing it to produce their products.   What is Recycled PU? Recycled PU, also known as recycled polyurethane, is made from recycled PU materials (such as production waste or discarded items) through processing and regeneration. Typically, these PU waste materials go through processes such as crushing, melting, and reshaping to be turned into reusable polyurethane raw materials. This process not only reduces waste generation but also decreases the dependence on new resources. Recycled PU not only retains the softness, wear resistance, and waterproof advantages of traditional PU but also has a more environmentally friendly production process. Therefore, recycled PU, which combines environmental protection and high performance, is an important material for the fashion and luggage industry to achieve sustainable development goals. Main Features of Recycled PU Environmentally Friendly: The production process of recycled PU uses recycled materials, reducing the exploitation of natural resources. This not only lowers the carbon footprint but also reduces the accumulation of PU materials in the natural environment. High Durability: Recycled PU materials, after modification treatment, maintain excellent tensile and tear resistance, making them very suitable for the frequent use and wear of daily backpack products. Waterproof and Easy to Clean: Similar to traditional PU, recycled PU has good waterproof performance, making it highly valuable in outdoor backpacks and sports bags. In addition, its surface is easy to clean, facilitating daily maintenance. Diversity and Design Flexibility: Recycled PU can be customized in different thicknesses, textures, and colors, allowing for a variety of styles and design options, enriching the appearance choices for backpacks.   The Production Process of Recycled PU 1.Collection and Sorting: Producers collect waste PU from post-consumer or industrial waste and sort it. 2.Crushing and Melting: The sorted PU waste is crushed and then melted to be reshaped at high temperatures. 3.Filtering and Treatment: Chemical treatment is used to remove impurities and maintain the stable performance of the PU material. 4.Reshaping and Processing: Finally, the material is reshaped into films or fabrics for production, creating the recycled PU materials we are familiar with. This production method is more energy-saving and environmentally friendly than synthetic PU materials, and it also reduces the dependence on chemicals.   Why Choose Recycled PU? For brands and consumers who focus on environmental protection and social responsibility, recycled PU represents a forward-looking choice. It not only reduces material waste and environmental pollution but also provides a sustainable alternative to traditional materials. Synberry is well aware of the importance of environmental protection to the industry, and we are committed to continuously introducing more recycled PU materials into our future backpack products, making every backpack a contributor to the protection of the Earth's resources.

Cork Leather: The Perfect Blend of Sustainability and Style Cork leather is a material made from the bark of cork oak trees, which offers natural, eco-friendly, and sustainable qualities. In recent years, as environmental awareness grows, cork leather has become increasingly popular in the fashion industry, especially in backpacks, footwear, and accessories. This material combines the beauty and texture of traditional leather with additional environmental benefits.   The Making of Cork Leather The process of making cork leather begins with the harvesting of cork bark. The bark is carefully stripped from the tree, without harming it. After being cleaned, dried, and compressed, the bark undergoes specialized processing to create leather-like material suitable for making a wide range of products. This sustainable process not only ensures high-quality products but also helps protect the environment.   Features of Cork Leather Cork leather is preferred by many designers and consumers due to its natural texture and lightweight properties. It is both durable and has a unique aesthetic, offering an eco-friendly alternative to traditional leather because its production process has a smaller environmental footprint. Moreover, cork leather’s water resistance and durability make it a popular choice for backpacks and other daily use items. Due to its breathability and antibacterial properties, cork leather is also favored for creating comfortable and health-conscious products. At Synberry, we are committed to providing high-quality, sustainable backpacks and accessories. We prioritize the use of eco-friendly materials and actively follow innovations in sustainable materials within the backpack industry. As a company with over 30 years of experience in manufacturing, we strive to blend environmental consciousness with stylish design, pushing the industry forward. Cork leather, as an innovative material, perfectly aligns with our commitment to sustainability and fashion quality.

Traditional leather production significantly harms the environment, requiring large amounts of water and energy, and releasing harmful chemicals that pollute soil and water. The demand for livestock also leads to deforestation and biodiversity loss, worsening the ecological crisis. With growing global awareness of sustainability, finding eco-friendly alternatives has become essential. The innovative use of reusable materials like apple waste to create leather alternatives is particularly important. Recently, the fashion and leather industries have sought solutions to reduce their environmental impact. A notable advancement is converting apple waste into leather alternatives, which helps minimize waste and promotes sustainability in an industry criticized for resource-intensive practices. The Danish company Beyond Leather Materials has partnered with polymer producer Covestro to develop an innovative leather alternative made from apple waste generated during the production of apple juice and cider. From Waste to High-End Material Every year, approximately 4 million tons of waste are produced globally from apple juice and cider production. This waste is often viewed as a useless burden, ultimately discarded or burned, leading to significant resource waste and environmental pollution. However, Beyond Leather Materials has creatively transformed these previously discarded materials into an eco-friendly leather alternative—a new type of leather material—through innovative technology. They begin by filtering out fibers such as seeds and stems from the apple waste, which contain high levels of polymers. This is followed by a series of reactions to create a strong and flexible material, which is then combined with a textile base layer. Finally, a protective layer produced by Covestro is applied to the surface. Beyond Leather has positioned this material as a preferred new-generation option for various industries and applications, including the backpack industry and furniture sector. In the near future, this material may even be used in automotive interiors. At Synberry, we are always focused on sustainable development and environmental innovation. We are confident in this emerging material that transforms apple waste into leather alternatives and see its enormous potential in the backpack industry. In the future, we plan to explore the application of this eco-friendly material in our products, creating backpacks that are both stylish and sustainable, meeting the dual demands of modern consumers for environmental friendliness and high quality. Through these efforts, we hope to contribute to protecting the Earth while providing our customers with more innovative choices.

In the rapidly evolving world of technology, RFID (Radio-Frequency Identification) and anti-RFID technologies are gaining traction in various industries, including the school backpack sector. RFID technology harnesses electromagnetic fields to automatically identify and track tags attached to various objects. In the backpack industry, embedding RFID tags within backpacks can offer a wealth of valuable information. To use this technology, simply hold a scanner within a few centimeters of the chip, and it will wirelessly read the data stored within the chip.   In the student backpack industry, RFID mainly serves the following purposes. Inventory Management: RFID tags significantly enhance inventory management by allowing manufacturers and retailers to monitor stock levels in real time. With RFID readers, staff can quickly scan items in a warehouse or store, ensuring accurate stock counts. This minimizes the risk of stockouts, where customers cannot find products, or overstocks, where excess inventory ties up resources. Customer Engagement: Brands can leverage RFID technology to create personalized experiences for customers. For example, when a customer scans their RFID-enabled backpack, they can access tailored content, including care instructions, usage tips, or even videos showcasing how to best utilize the product. This engagement not only enhances customer satisfaction but also builds brand loyalty.   Anti-Theft Measures: RFID tags can play a critical role in theft prevention and recovery. When a backpack with an RFID tag is stolen, RFID readers can help locate it by tracking its movements within range. Some companies even partner with law enforcement to facilitate the recovery process, adding an extra layer of security for consumers. Although RFID technology offers many conveniences, the ability to quickly read information wirelessly without authorization has also raised concerns about data breaches. As a result, anti-RFID technology—RFID shielding materials has emerged. Some backpacks now come equipped with RFID shielding pockets designed to block the sensitive information stored in RFID tags embedded in items such as passports and credit cards. These pockets utilize special materials that prevent unauthorized scanners from reading the data, effectively protecting customers' privacy and ensuring their security while traveling or shopping.   In summary, RFID technology is enhancing backpacks with improved inventory control and personalized customer experiences, while anti-RFID shielding preserves privacy. It's a win-win combination for functionality and security in the backpack industry. Synberry is committed to respecting and safeguarding our customers' personal information. The adoption of RFID technology is aimed at enhancing our warehouse management and improving our service to customers.

This is undoubtedly an eternal topic that the backpack industry has been continuously exploring since its inception. In the design and manufacturing process of backpacks, there is no uniform standard answer to how to create products that are not only aesthetically pleasing but also favored by a wide range of customers. After all, the feeling of beauty is subjective, and everyone's pursuit and definition of beauty are diverse. Children always have a special fondness for cartoon elements, and kids cute backpacks are decorated with lovely and charming animated characters. Who could say that their childhood lacked a lovely and charming animated character? These characters have almost become an indispensable companion of their childhood. Young people pursue fashion, and they tend to choose backpacks with bright colors and bold designs, which can quickly attract their attention. However, for mature and steady middle-aged people, they may not be attracted by these bold designs, and they prefer classic and timeless design styles. Retro and classic elements can often evoke good and interesting memories in their hearts. Although everyone's perception of beauty is different, there are some universally recognized basic principles that comply with the public's aesthetic when designing popular backpacks.   Color Matching and Patterns To create an eye-catching backpack, the first step is to carefully select the color matching. Whether it is soft pastel colors, natural earth tones, or bright and vibrant colors, they can create a unique style. Skillfully integrating popular patterns, such as flowers, geometric shapes, or abstract art, can enhance the visual impact. The key is to ensure the harmony and unity of color and pattern to create an eye-catching overall effect.   Material Selection The material of the backpack not only affects its durability but also greatly determines its appearance. Using high-quality fabrics, such as canvas, denim, or eco-friendly materials, can enhance the design level. Consider using materials with a rich texture, such as corduroy or suede, to add a sense of hierarchy. At the same time, the clever combination of contrasting materials, such as leather trim or mesh pockets, can add a touch of fun and complexity to the design. It is worth mentioning that eco-friendly materials are indeed an intrinsic aesthetic element in backpack design. They not only provide a natural and simple beauty visually but also reflect care and responsibility for the environment in material selection. This environmentally friendly design concept is a powerful aesthetic force in itself, which can touch people's yearning for nature and a sustainable lifestyle.   Practical Details Beauty and practicality go hand in hand. Incorporating fashionable and practical details into backpack design, such as magnetic buckles, unique zippers, or decorative straps, not only enhances visual beauty but also does not affect its practicality. Carefully designed external pockets and customizable straps further enhance the daily practicality and visual appeal of the backpack. Exquisite sewing techniques and delicate edge processing show the backpack's ultimate pursuit of detail, highlighting its craftsmanship. Personalized Options Allowing customers to personalize their backpacks can make them more attractive. Providing options such as detachable patches, embroidered names, or color embellishments allows users to express their personality. This not only makes the backpack unique but also adds aesthetic elements that resonate with consumers.   In summary, designing a backpack that is both beautiful and practical is an art and a challenge. It requires designers to deeply understand the aesthetic preferences of the target user group while continuously innovating to perfectly combine fashion elements with practical functions. From lively cartoon patterns to simple modern designs, from the selection of eco-friendly materials to personalized customization services, every detail reflects the designer's pursuit of beauty and deep insight into user needs. In this diverse world, a backpack is not only a tool for carrying items but also a reflection of personal style and attitude towards life. A successful backpack design not only meets functional needs but also touches people's hearts and conveys emotions, becoming an indispensable part of people's lives. Synberry has always been committed to the aesthetics of backpacks, combining the continuous progress of design technology and the emergence of new materials. We believe that future backpack designs will be more diverse, personalized, and visually attractive. Let us look forward to and create more beautiful and practical backpacks together, making them shine in people's lives.

The materials used directly determine the waterproof performance of a backpack. Previously, In the article "Which material is best for laptop bags?", we previously introduced some commonly used waterproof materials. However, the overall waterproof performance of a backpack depends not only on the materials but also on the waterproof capabilities of the zippers. Zippers are one of the weakest points in any waterproof gear. If designed poorly, water can seep in, compromising the integrity of the equipment. Therefore, high-quality zippers are essential for maintaining waterproof standards, especially in outdoor environments. The two common types of zipper waterproofing treatments are waterproof zippers and water-resistant zippers. Understanding the difference between waterproof and water-resistant zippers is crucial. Water-resistant zippers are usually treated with a coating that helps repel water, making them suitable for light rain or splashes. In contrast, waterproof zippers are designed to completely prevent water from entering. These zippers typically feature a sealed or taped construction to ensure comprehensive protection against moisture.   Types of Waterproof Zippers 1.Coated Zippers: These zippers have a waterproof coating that helps repel water and are commonly found in many outdoor products. 2.Taped Zippers: Taped zippers have waterproof tape covering the seams, sealing the zipper and preventing water ingress. This type is often found in high-end outdoor gear. Additionally, some designs of waterproof backpacks also enhance waterproofing, such as fabric flaps covering the zippers, effectively preventing rainwater from entering.

Whether a transparent backpack is a good design is indeed a controversial topic.   Proponents argue that this transparent design allows users to see what's inside without unzipping, providing a clear view at a glance. Have you ever been about to leave home and start your trip, only to suddenly wonder if you've packed something important (like keys, driver's license, wallet, etc.)? If you use a transparent backpack, you wouldn't need to open it to check again. Moreover, this unique design might attract more attention. According to our market research, backpacks in this transparent style are more popular among children, especially little girls. Perhaps this pure design style is more appealing to little girls' hearts. However, some people believe that this kind of backpack does not protect privacy since everything inside is visible, and the special backpack itself is more eye-catching. I think many introverted people might not like it when others' gaze lingers on their bag and counts the items inside while they are shopping.   Regarding privacy issues, using this kind of backpack in special occasions (such as sports events, large-scale activities) should be a good idea, as it allows staff to quickly check items and reduce potential risks, especially in popular large-event venues.   Ultimately, this unique design cannot please everyone, and this is true for most designs. So, do you think this transparent-style backpack is suitable for you?  

For most people, a computer is much more expensive than a computer bag, and it contains a lot of data that we use daily, which may even exceed the value of the computer itself.

What are the cons of tyvek？Previously, we discussed the advantages of Tyvek. Now let's talk about some of the material's disadvantages.   The feel of wrinkles: You must be familiar with this sensation. Tyvek has a texture that feels like crumpled paper. If you want to know what this material feels like, just take a piece of A4 paper, crumple it up, and then smooth it out on your desk. Yes, it's that unique feeling. Of course, for some people, this may not be a disadvantage at all. What do you think? Expensive price: Why is DuPont paper so expensive? This is probably a question that many people care about. As mentioned earlier, it is a great invention, and DuPont paper is a product with many unique features, combining the advantages of many other materials. I believe this is why it is more expensive than other traditional materials such as nylon or PU leather. Its high production cost and unique manufacturing process are also one of the factors contributing to its high price.   Service life: Unfortunately, I think this is the biggest disadvantage of Tyvek Backpack products. As a company dedicated to providing customers with satisfactory services, we must admit that the service life of Tyvek Backpack is not as long as products made from other traditional materials（such as webbing, PU Glitte, Nylon ）. According to professional testing in our laboratory, the service life of this material is about 4-5 years, although this can also meet the life expectancy requirements of most people for backpacks.
