What is the production process of single-sided fog TPU film?

Single-sided fog TPU film is a polyurethane film with high transparency, high elasticity and good wear resistance. Its production process mainly includes the following steps:

1. Raw material preparation: First, you need to prepare TPU particles, which are the basic raw materials for producing TPU films.

2. Melt extrusion: Melt TPU particles at high temperature and extrude them into a film through an extruder.

3. Cooling and shaping: The extruded TPU film is cooled on the cooling roller to shape it and maintain the required thickness and size.

4. Single-sided atomization treatment: This is a key step in the production of single-sided fog TPU film. Through a special atomization process, one side of the film is formed with a fine rough surface, increasing its friction coefficient while keeping the other side smooth.

5. Stretching and shaping: The film is biaxially stretched to improve its strength and durability.

6. Rewinding and packaging: Rewind the produced TPU film and package it for easy transportation and use.

7. Quality inspection: Strict quality inspection is required throughout the entire production process to ensure that the product meets relevant quality standards.

Single-sided fog TPU film is widely used in shoe materials, clothing, medical supplies and other fields due to its unique properties. Fine control of the production process is the key to ensuring product quality.
