Advantages of using PVC leather in bag manufacturing
1.Versatility and aesthetics The unique texture of PVC leather offers great design flexibility. Brands and manufacturers using PVC leather can create eye-catching bag designs in a variety of colors, textures and patterns. It can mimic the look of materials such as leather or create a unique transparent look in its natural form.
2.Durability and longevity. pvc leather’s high heat and abrasion resistance makes it a great choice for everyday, travel or heavy duty bags. It can withstand harsh conditions, such as exposure to moisture or extreme temperatures, without compromising quality. These qualities ensure that PVC leather bags maintain their structural integrity and visual appeal for over a decade to come.
3.Affordable. PVC leather is an affordable material compared to leather and other fabrics. Manufacturers use it to create stylish bags without compromising on their visual appeal as well as quality.

3.Affordable:PU leather is an affordable fabric for backpacks. The appearance of backpacks made of it can be comparable to that of leather bags, but the price is much lower!
4.Easy to clean: PU leather material is very easy to clean, you just need to wipe it with a damp cloth to restore a clean backpack.
PVC leather manufacturing bag shortcomings
- Flexibility:PVC leather is usually flexible, but if it is to make highly flexible and soft bags may not be suitable for the use of PVC leather.
- heat sensitivity:PVC leather is sensitive to high heat. Manufacturers, suppliers and consumers should avoid exposing PVC leather bags to extreme heat when storing or transporting them, as this can compromise their structural integrity and cause them to deform in value.
- Weight:PVC leather is slightly heavier than other synthetic materials. For travel convenience or other reasons, people who worry about the weight of the backpack to avoid using PVC leather bag
- UV resistance:PVC leather is susceptible to UV degradation, especially when exposed to sunlight for long periods of time. Without proper protection, this material may fade or become brittle over time. Manufacturers can overcome this problem by using UV resistant additives or coatings.
- Environmental concerns:As an oh petroleum-based product, PVC leather may have a negative impact on the environment. Although environmentally friendly alternatives to PVC leather exist, the production of traditional PVC leather generates plastic waste and often uses harmful chemical additives. Manufacturers using PVC leather should implement appropriate recycling and waste management measures to mitigate its environmental impacts.
Disadvantages of PU leather for bag manufacturing
- Plastic texture. PU akpụkpọ anụ has a strong plastic texture, and bags made from it will look cheap and low quality. Can’t imitate the glossy feeling of real leather.
- Odor irritation. Because PU leather for petrochemical synthetic materials, PU leather leather odor and leather is very different, PU leather leather smells like plastic or chemicals, while the smell of leather is more natural, almost undetectable.
- Durability. PU leather leather’s durability is not good, it is easy to be pierced or torn. the service life of PU leather is about 1-2 years, when the PU leather leather aging will appear after the phenomenon of peeling, cracking.

- VOC emissions VOCs are a group of chemicals that are released into the air in the form of gases from certain products, including certain adhesives and coatings used in the production of PU leather. These chemicals can cause a range of health problems (headaches, dizziness, and eye, nose, and throat problems).
- Heavy metals: for example lead and cadmium. These metals are toxic to humans and animals, and exposure to high concentrations can cause serious health problems, including nerve and kidney damage and cancer.

But in terms of cleaning and maintenance, PU leather and PVC leather are much easier.
In terms of ethical and environmental issues, many people will think that killing animals is unethical and avoid genuine leather, but think about it from another angle, is genuine leather really not environmentally friendly. In the case of cowhide, which is widely used and hard-wearing, leather comes from beef cattle that have been bred. This means that the leather industry is actually a by-product of the livestock and beef industries. Utilizing cowhide, which is not loved by the public, actually reduces waste.

Mmechi
When choosing whether to use PVC or PU leather, it is important to consider their advantages and disadvantages as well as their impact on the environment PVC leather is favored for its durability, versatility, and lower cost, and is particularly suited to applications where water resistance and ease of cleaning are required. However, there are negative environmental impacts associated with its manufacture, such as dioxin emissions and persistent waste issues, which need to be treated with caution. In contrast, while PU leather is more simulated and affordable, it also suffers from environmental issues such as VOC emissions and heavy metal releases, and is less durable.
From a sustainability point of view, leather is relatively more environmentally friendly as a biodegradable material and as a by-product of animal husbandry. Although it requires strict management and handling to avoid environmental pollution, under the right conditions leather is still an option with lasting value and texture.
Therefore, the selection of the right leather material should take into account functional needs, durability, cost, and environmental impact. In practical applications, the recovery and recycling of materials should also be promoted to minimize resource wastage and environmental burden.
