Polyethylene terephthalate (PET) film is a common material used in adhesive, electronic, die-cutting, printing and other industries. There is a large market demand in China every year. However, due to the backward substrate and silicon coating technology, domestic PET profiling film still relies on imports for high-end products. The main factors affecting the quality of PET membrane are as follows:

1. Substrate: The silicone release agent is coated on the surface of the PET film. The quality of the substrate directly affects its performance. Domestic PET film substrates lag behind foreign countries in thickness control and thermal shrinkage.

Residual Adhesion Rate: Residual Adhesion Rate refers to the force of separating paper after the first peeling and the second peeling. The calculated data mainly reflect the curing effect of silicone oil.

3. Peeling force: Peeling force directly affects the performance of PET film. The tolerance range of peeling force in general industry standard is (+15%). Dongguan Hongyuan Film Co., Ltd. has been engaged in the PET film industry for many years. Various kinds of PET materials have rich experience and professional technical control, which can control the peeling force stability of the separated film very well.

4. Processing environment: With the increasing progress of various products and the improvement of quality technology, the requirements for cleanliness of PET parting membranes are becoming stricter and stricter, especially in the electronic film cutting industry. Dongguan Hongyuan Film Co., Ltd. now all products are produced in 10,000 class dust-free workshop, divided into sections; leading peers in quality.

Of course, there are many factors affecting the quality of PET separating film in actual production. Different industries, different companies and different processes have different requirements for the use of various films. Dongguan Hongyuan Film Co., Ltd. has been committed to product quality improvement, promotion and application. We will uphold the tenet of "satisfying customers with high quality products and serving customers with sincere reputation", and wholeheartedly work together with our customers to create brilliance with exquisite technology, exquisite quality and honest service.
