DN114pu material 0.6 mm packing material off paper pattern large quantity spot

PU leather is more complex in the manufacturing process than PVC leather. The bottom fabric of PU is a canvas PU material with good tensile strength, so it can not only be coated on the bottom fabric, but also include the middle bottom fabric, where the endless fabric can be seen from the outside. PU leather has better physical properties than PVC leather, with twists, softness, tensile strength, and breathability (without PVC). The patterns on PVC leather are hot-pressed using a pattern roller made of steel.

Products Description

Synthetic leather other than general leather is collectively referred to as PVC, PU leather, Artificial leather or imitation leather. PVC and PU are both polyvinyl chloride (one of the plastics), but their manufacturing processes are different.

In the manufacturing process of PVC leather, firstly, the plastic particles should be melted to make dough, which should be evenly coated on the T/C knitting base according to the specified thickness, and then enter the foam furnace, which has the flexibility to adapt to the production of a variety of products. At the same time, the surface treatment (dyeing, embossing, polishing, matting, grinding stone) should be carried out.

The bottom fabric of PU is a canvas PU material with good tensile strength, so it can not only be coated on the bottom fabric, but also include the middle bottom fabric, where the endless fabric can be seen from the outside. PU leather has better physical properties than PVC leather, with twists, softness, tensile strength, and breathability (without PVC). The patterns on PVC leather are hot-pressed using a pattern roller made of steel. The pattern of PU leather is to use a pattern paper to apply a hot sticker to the surface of semi-finished leather, wait for cooling, and then separate the paper skin for surface treatment. The price of PU leather is more than twice that of PVC leather, and some special requirements require that the price of PU leather be 2-3 times higher than that of PVC leather. The patterned paper required for regular PU leather can only be discarded 4-5 times. Due to the long service life of fancy rollers, the cost of PU leather is higher than that of PVC leather. There are also some differences in the applicability of these two materials. In the case of footwear, PVC leather is often used to make parts or children's shoes that do not bear lining or weight. PU leather can be applied to the fabric or weight bearing parts of footwear. The most commonly used bag is PVC leather. Because the things in the bag are different from the feet in the shoes, they won't heat up. No need to bear personal weight.

PU leather

Due to the flexibility, ductility, toughness, instability affected by temperature, environmental friendliness, and non-compliance with social and commodity market requirements of PVC products, PU synthetic leather has emerged.

Initially, PU leather achieved unprecedented development and use in clothing, laying a solid foundation for the diversification and multi quality development of PU leather in the future. Subsequently, PU leather achieved multi quality development in products such as bags and shoes. However, the production and manufacturing of PU synthetic leather became more complex, with higher raw material prices. PU leather not only met social needs but also generated corresponding high prices.

The difference between PU and PVC is relatively easy. From the corners, the cost is much thicker than PVC, and there are also differences in the feel. PU has a soft feel. PVC has a harder feel. It can also be burned with fire. The taste of PU is much lighter than that of PVC.
