Plastic Coating Polyethylene Pellets Transparent And High Flow

Polyethylene pellet coating grade transparent and high flow for plastic coating
The following is an introduction to our materials:

The plastic coating process is a surface treatment technology that coats the surface of various substrates (such as metal, plastic, wood, etc.) with a layer of plastic so that it can maintain the characteristics of the original substrate and have the characteristics of plastic. Certain excellent properties, such as corrosion resistance, wear resistance, electrical insulation, self-lubrication, etc. This process is of great significance for expanding the application range of products and improving their economic value.

The plastic coating process can be roughly divided into three steps:

1. Pretreatment: First, the substrate needs to be prepared, including removing all grease, contaminants, and rust. At this stage, a lot of chemicals are used, mainly including rust remover, degreasing agent, surface conditioner, phosphating agent, etc. Pretreatment is a critical step to ensure that the plastic adheres firmly to the substrate surface.
2. Plastic coating: After pretreatment, plastic powder is used to apply plastic to the substrate by spraying, scraping, dipping, etc. The key to this step is to ensure that the surface coating of the coated substrate is uniform and consistent in thickness to avoid problems such as thin coating, missing coating, and rubbing off.
3. Post-processing: After coating is completed, baking or curing processing is required. This step requires strict control of processing technology, temperature and time to avoid problems such as color difference, over-baking or insufficient curing.

In specific implementation, for small quantities of product workpieces, manual powder spraying devices and natural drying, sun drying, air drying and other processing methods can usually be used; while for mass-produced product workpieces, automatic powder spraying devices and Low-temperature drying and other efficient and stable processing methods.

The plastic coating process has a wide range of applications. It can be used in the manufacturing of instant noodle bowls, melon seed bag packaging, paper cup lamination and other products. It can also be used in the production of release paper on tapes, liquid food packaging, breathable masterbatch and other products.

The plastic coating process is an efficient and practical surface treatment technology that can significantly improve the performance and value of products and meet the needs of different fields.
