Offline coated PP sheet roll

Brif Intro

Offline coated PP sheet roll refer to a process in which PP (polypropylene) sheets are coated outside the production line. PP sheet is a commonly used plastic packaging material with good wear resistance, chemical resistance and heat resistance, but its surface gloss and printability are poor. Through the offline coating process, a functional coating can be applied to the surface of the PP sheet to improve its surface properties, making it more suitable for processing processes such as printing, lamination, and blistering.

Specifications of offline coated PP sheet roll

Characteristics of offline coated PP sheet roll

• Lightweight and durable: PP sheet rolls are usually lighter than other plastic materials, while having good durability and not easy to break.
• Chemical stability: PP sheet rolls have high resistance to chemical corrosion, so they are suitable for many different environments and applications.
• High temperature resistance: PP sheet rolls have a high melting point and heat deformation temperature, and can withstand high temperatures within a certain range.
• Good processing performance: PP sheet rolls can be easily cut, bent, welded and other processed.
• Low cost: PP sheet rolls are a relatively cheap material, so they have a high cost performance.

Advantages of offline coated PP sheet roll

• Excellent mechanical properties: PP sheet rolls have good tensile strength and impact strength, which can meet the requirements of various packaging and industrial applications.
• Excellent coating surface: The surface of the sheet roll is specially coated with a flat, smooth and uniform coating layer, which is suitable for printing, laminating and other processing technologies.
• Multiple colors and specifications: A variety of colors and specifications are available to meet the needs and application scenarios of different customers.
• Environmental protection and recyclability: The sheet roll coating material meets the relevant environmental standards and regulatory requirements, can be recycled and reprocessed, and reduce the impact on the environment.

Production process of PP sheet roll

The production process of offline coated PP sheet roll usually includes the following steps:

Mixing: Mixing PP resin with other additives such as pigments and antistatic agents.

Extrusion: The mixture is heated and extruded into a film or sheet.

Cooling: Cooling the film or sheet to room temperature.

Shaping: The film or sheet is heated and blistered into the desired shape.

Trimming: Trimming molded parts as needed, such as cutting, stamping, or printing.

The process flow of offline coating of PP sheet rolls usually includes the following steps:

Substrate preparation: Wash and dry the PP sheet rolls to ensure that the coating surface is clean and flat.

Coating preparation: According to the required coating properties, the coating is mixed and filtered in proportion.

Coating: Use a suitable coating method to evenly apply the coating on the surface of the PP sheet.

Drying: Remove the solvent in the coating by heating or other means to solidify the coating.

Reeling: Reel and package the coated PP sheet rolls.
