Solution

With the continuous development of modern production technology, the application of plastic films is becoming more and more extensive, and LDPE (low-density polyethylene) and CPP (polypropylene cast film) cast films are favored for their good physical properties and chemical stability. However, due to problems such as impurities and particulate matter in the raw materials during the production process, the quality of these films is often difficult to guarantee. In order to solve this problem, by adding a plunger melt filter, improving the quality of LDPE cast film and CPP cast film products has become a solution chosen by many customers.

First, let's take a look at the production methods of LDPE and CPP cast films. Both LDPE and CPP cast films are produced using extrusion production lines, of which single-layer cast and multi-layer co-extrusion cast are two common production methods. Single-layer cast refers to heating and melting plastic particles, and then extruding the molten material into a film through an extruder. Multi-layer co-extrusion cast refers to heating and melting plastic particles of different materials separately, and then extruding them into multi-layer films through an extruder.

However, since impurities and particulate matter are inevitable in the production process, these problems will have an adverse effect on the quality of the product. In order to solve this problem, we installed a plunger melt filter on the extruder. The plunger melt filter is an efficient filtering device that can filter out impurities and particles in the molten material, thereby improving the quality of the extruded product.

The plunger melt filter uses a high-precision filter screen, which can effectively filter out tiny particles with a diameter of less than a few microns, thereby ensuring the purity of the product. In addition, the plunger melt filter with backwashing function can automatically clean and automatically discharge sewage, thereby effectively reducing the maintenance cost and downtime of the equipment.

By adding a plunger melt filter, the product quality of LDPE cast film and CPP cast film has been significantly improved. Not only can it improve the transparency and glossiness of the product, but it can also reduce the defect rate and return rate of the product, greatly improving production efficiency and economic benefits.

The Su Kebang plunger melt filter is an efficient filtering device that can effectively improve the product quality of LDPE cast film and CPP cast film. We will continue to uphold the concept of professionalism, responsibility and innovation to provide customers with better melt filter products and services.
