Famous China Leaf Disc Filters for Plastic Film Industry - Top Suppliers & Factory Solutions Manufacturer, Company

Leaf disc filters play a crucial role in polymer film filtration by effectively removing impurities, contaminants, and particles from the polymer melt or solution prior to the film formation process. This essential function ensures the production of high-quality, defect-free polymer films, making them indispensable in the industry, Compared to traditional melt filter elements, leaf disc filters offer significant advantages, including a larger effective filtration area, enhanced stability due to their robust mechanical structure, and ease of maintenance. These features make them particularly suitable for high impurity environments, high output requirements, and high-pressure conditions. As a leading supplier in China, our factory is dedicated to providing premium leaf disc filters tailored to meet the specific needs of your polymer film production processes

Product Description

Polymer Leaf Disc Filters

Our Polymer leaf disc filters are well-developed filtration products after we are delicate to developing and improving on it for many years by using advanced professional welding equipment and process.

It has the characteristics of the resistance to high pressure & temperature, to chemical corrosion; and good permeability, large dirt-holding capacity, reliable performance and long lifetime with high strength, tenacity, excellent impact resistance, and can be repeatedly used after cleaning. It is mainly used for polymer filtration in the production line of BOPA, BOPET, and BOPP, in order to remove polymer gel, coagulating agent, catalyst, and other solid impurities. Polymer Discs filters are widely applied in the industry of film, polyester polymer, spinning, packaging materials, engineering plastics, oil, chemical and others.

How to Choose Between Filter Discs and Melt Filter Elements?

It depends on the specific production process requirements and economic benefit considerations.

Situations where filter discs are preferred:

The Recycled Material (Recycled material) has a very high impurity content.
Continuous production, pursuing an extremely long replacement cycle and the highest equipment stability.
The melt pressure is extremely high and the working conditions are harsh.
From a long-term economic perspective, accepting a higher initial investment in exchange for lower long-term operating costs.

Situations where melt filter elements are preferred:

The raw materials are relatively clean with low impurity content.
It has extremely high requirements for filtration accuracy (some filter elements can provide even more extreme accuracy).
Due to limited space, a more compact filtration solution is needed.
The production batches are variable and require flexible adjustments, or the initial investment budget is limited.

Frequently Asked Questions

What are the primary applications of Polymer Leaf Disc Filters?

They are mainly used for polymer filtration in BOPA, BOPET, and BOPP production lines to remove polymer gel, coagulating agents, catalysts, and other solid impurities, and are widely applied in films, spinning, packaging, and engineering plastics.

What materials are these disc filters made of?

The filter media options include stainless steel sintered fiber, multi-layer sintered stainless steel wire, and sintered metal powder to ensure high durability.

Can these leaf disc filters be cleaned and reused?

Yes, the filter elements are designed for long lifetimes and can be repeatedly cleaned and reused, typically utilizing ultrasonic cleaning methods.

What are the operating temperature and pressure limits?

These filters can withstand working pressures of up to ≤31.7MPa and working temperatures up to ≤300℃, with an allowable pressure differential of ≤10Mpa.

When should I choose filter discs over melt filter elements?

Filter discs are preferred when processing materials with high impurity content (like recycled plastics), in continuous production requiring long replacement cycles, under extreme melt pressure, or when looking to lower long-term operating costs despite a higher initial investment.
