EnglishPapers coated with polyethylene (PE) are an essential material used in many different types of packaging. These papers provide a variety of benefits, including the ability to protect products from moisture and grease. The paper is also easy to print on and offers good printability. In addition, PE Coated Kraft Paper Bowl are biodegradable and can be composted in environmentally friendly ways. In order to produce high-quality PE-coated paper, manufacturers must follow strict quality control and testing procedures. These measures ensure that the paper meets specific standards and can withstand various conditions.
The process of producing PE-coated paper involves a variety of steps, from raw materials inspection to finished product inspection. The first step is to inspect the raw materials, which include both the paper and the polyethylene. This ensures that the paper has the proper thickness and water resistance for the intended application. Then, the PE is added to the paper using a special technique.
