PU Leather In Bag Manufacturing – The Ultimate Guide

PU Leather

In the world of bag manufacturing, the right material can make or break a design. Not only does it heavily influence the aesthetic of the bag, but it also impacts its durability and quality. The usage of materials will define a brand and its place in the market, which is why it’s crucial for any bag designer or manufacturer to do their due diligence before beginning production. Below, we’ll be sharing everything you need to know about PU leather for bag manufacturing, so that you can decide if it will be the winning material for your designs.

What Is PU Leather?

PU leather, commonly referred to as polyurethane leather, synthetic leather, or faux leather, is an artificial material that imitates the look and feel of genuine leather. It achieves a leather-like texture and appearance by applying a polyurethane coating to a fabric backing. PU leather offers a versatile and vegan-friendly alternative to genuine leather. It has found immense popularity in the fashion and bag manufacturing industries since its creation for its numerous benefits.

The Advantages Of Using PU Leather In Bag Manufacturing

  1. Aesthetics & Variety. PU leather is available in a wide range of colors, patterns, textures, and shapes. This allows bag manufacturers and designers to create diverse designs that cater to any aesthetic. It can replicate the look of genuine leather, suede, or exotic animal skins, providing a luxurious and stylish alternative to genuine leather. The fashion industry widely uses PU leather to create a range of products, including everyday tote bags, practical backpacks, and eye-catching evening clutches..
  2. Affordability. PU leather offers a significant advantage in terms of affordability when compared to genuine leather. Since it is easier to produce, PU leather generally comes with a lower price tag. It’s a cost-effective option that doesn’t sacrifice visual appeal or quality.
  3. Durability & Versatility. PU leather offers a balance of durability and versatility, making it suitable for various applications. While high-quality PU leather can withstand regular use for an extended period, it’s important to note that lower-quality PU materials may exhibit signs of wear and tear sooner. These lower-grade variations can show signs of scratches and diminished quality after approximately 6 months of use. However, well-crafted PU leather variants maintain their appearance and structural integrity, exhibiting resistance to fading, cracking, and peeling for up to 5 years or more.
  4. Vegan-Friendly & Cruelty-Free. One of the most appealing qualities of PU leather is that it’s made without the use of animals or animal byproducts. This makes it an excellent choice for vegans or anyone else who has ethical concerns with animal products. PU leather is currently the most popular type of faux leather. It allows bag designers and manufacturers to easily cater to the growing demand for cruelty-free and vegan products.
  5. EU REACH Compliance. PU leather easily meets the European Union’s Registration, Evaluation, Authorization, and Restriction of Chemicals (REACH) standards. This ensures that PU leather used in bag production adheres to stringent safety and environmental regulations, giving manufacturers and consumers peace of mind regarding the material’s compliance with health and environmental standards.

The Limitations of Using PU Leather in Bag Manufacturing

  1. Breathability. PU leather replicates genuine leather in many ways, but one thing it lacks is its natural breathability properties. Its lower level of ventilation can lead to moisture build-up inside the bag. Proper bag design and incorporation of ventilation features can effectively prevent these issues.
  2. Environmental Impact. PU leather is often considered a more sustainable alternative to genuine leather. It is still a synthetic material derived from petroleum-based sources. The production of PU leather involves chemical processes that can have environmental implications. However, the industry has made significant advancements, including the development of eco-friendly alternatives such as water-based PU. Water-based PU leather is produced using water-based formulations instead of solvent-based ones, reducing the reliance on harmful chemicals and minimizing its negative environmental impact.
  3. Heat Sensitivity. PU leather is more susceptible to damage from heat compared to genuine leather. Exposure to high temperatures or direct sunlight for extended periods can cause PU leather to warp, fade, or lose its original texture. Bag users should be cautious and avoid leaving PU leather bags in hot environments or exposing them to excessive sunlight to maintain their quality and appearance.

PU Leather Production & Manufacturing Considerations

Working with PU leather involves similar manufacturing processes as genuine leather. This versatile material can be cut, stitched, and assembled using specialized sewing machines and tools. The lightweight nature of PU leather simplifies the working process. This allows for easy handling, while its visual appeal can be enhanced through embossing, printing, or embellishments.

A bag manufacturer wanting to work with PU leather will need to use specialized blades, knives, and PU leather-cutting machines to ensure precise cuts. Sewing machines with Teflon-coated or roller presser feet are recommended to minimize friction and prevent sticking, and large-sized needles for heavy fabrics should be used. By investing in the necessary equipment and training production teams on specialized techniques, manufacturers can ensure the efficient and precise manufacturing of high-quality PU leather bags.

PU Leather Sustainability & Environmental Impact

The environmental impact of PU leather versus genuine leather is a subject of significant debate within the sustainable fashion community.

As a cruelty-free product with no animal origins, PU leather is undoubtedly the more ethical choice. It is preferred by vegans and vegetarians across the globe. This is why PU leather is often considered to be more sustainable. However, the synthetic nature and petroleum-based origins of PU leather can have a negative environmental impact.

PU leather production often involves the use of toxic chemicals like dimethylformamide, and the material is reliant on the fossil fuel industry. These reasons make people question if PU leather truly is a sustainable choice. However, new technologies mean that eco-friendly PU leather alternatives are emerging at a faster rate than ever before, utilizing recycled materials and water-based coatings. Manufacturers that want to make a positive difference in the industry can choose PU leather from responsible sources and prioritize eco-friendly production practices to reduce its environmental impact further.


PU leather presents a compelling option for bag manufacturers, combining style, durability, affordability, and ethics. Its versatility and ease of maintenance make it an attractive choice for a wide range of bag types. While it may have limitations, such as reduced breathability, and it historically comes with environmental concerns, strategic design and developing eco-friendly options can help manufacturers overcome the challenges typically associated with PU. From on-trend bags that don’t cost a fortune to cruelty-free designs that cater to the vegan market, PU leather will be a fantastic choice for many different types of bag manufacturers.
