EVA (ethylene vinyl acetate) sheet is a type of material that is commonly used in leather bags for a few different reasons:
Durability: EVA sheet is a durable material that can withstand wear and tear, making it ideal for use as a lining or reinforcement in leather bags.
Water resistance: EVA sheet is water-resistant, which means that it can help to protect the contents of the bag from water damage.
Shape retention: EVA sheet can help to maintain the shape of the bag and prevent it from collapsing or losing its structure over time.
Softness: EVA sheet is also relatively soft and flexible, which means that it can help to provide a cushioning effect and make the bag more comfortable to carry.
Overall, the use of EVA sheet in leather bags can help to improve their durability, water resistance, and shape retention, while also providing a soft and comfortable interior lining.
