Barrier Paper is a special type of paper that has excellent barrier properties and can effectively prevent air, moisture, light, grease, oxygen and other external elements from penetrating.The future prospects for barrier paper are quite promising, driven by growing demand and technological advancements.

With the improvement of consumer requirements for product protection and packaging, as well as the continuous progress of technology, the demand for barrier paper will continue to grow。

The coating process is essential for producing high-performance barrier paper because it allows for customization of the coating liquid's composition and thickness according to the product requirements to achieve the desired barrier properties.Here is an overview of the general steps and key aspects of the coating process:

1.Selection of base paper:To achieve function of barrier properties,selection of base paper plays a key role in coating.According to the request of barrier,the base of PE,PP,Aluminum Foil and Bleached Paper are always selected for base paper.Bleached paper is often used for product packaging because it provides a certain level of barrier performance. While its barrier properties are not as strong as specialized barrier materials, it can still offer adequate protection in some cases.

2.Coating process:As the higher demand for the barrier properties,many coating methods have been developed.Like gravure coater,blade knife coater,air knife coater and so on.For meeting the demand of package and considering of the cost,our company,QINGDAO JIERUIXIN MACHINERY&TECHNOLOGY CO LTD,usually recommend our customer for choosing blade knife coater to achieve precisely coating and cost control.We have rich experience in setting up coating lines for customers from more than 20 countries.

3.Coating chemicals:Besides the barrier properties of the base paper,the coating chemicals also provide base paper barrier properties to prevent air,water,grease and etc.We have mature formula of chemicals supplied for our customers and steadily used in the coating machine line to get products with stable quality and excellent barrier properties,adaptable for precision coating at high speed and high yield.

The coating process is essential for producing high-performance barrier paper because it allows for customization of the coating liquid's composition and thickness according to the product requirements to achieve the desired barrier properties. Different types of coating methods and material combinations can be used to manufacture barrier paper with various barrier performance levels, making it suitable for a range of applications, such as food packaging, pharmaceutical packaging, electronic product packaging, and more.Our company QINGDAO JIERUIXIN Machinery and Technology Co., Ltd. focuses on the development and manufacture of coating processes and equipment.
