PP/PE/PA/PETG/EVOH Multilayer Barrier Sheet Co-Extrusion Line：An Innovative Force Shaping the Future of Packaging

PP/PE/PA/PETG/EVOH Multilayer Barrier Sheet Co-extrusion Line：an innovative force shaping the future of packaging

Plastic packaging sheets are commonly used in the manufacture of disposable plastic cups, plates, bowls, discs, boxes and other thermoformed products, and are widely used in the packaging of food, vegetables, fruits, beverages, dairy products, and industrial parts and components. With its excellent flexibility and high transparency, plastic packaging sheet can be easily moulded into a variety of fashionable styles to meet the diversified needs of the market. Compared with glass products, plastic packaging sheet is more resistant to breakage, light weight, easy to transport and storage, greatly reducing logistics costs.

However, the packaging industry is very strict on the performance requirements of plastic packaging sheet, it is expected to be able to have mechanical strength, heat resistance, cold resistance, effective barrier to gas and water vapour, glossy and transparent appearance, good heat sealing performance, excellent printing adaptability and non-toxic and harmless properties. Single-layer plastic sheet, although it has certain advantages, but obviously can not fully meet these high-performance requirements, especially in the packaging of oxygen-sensitive commodities, its barrier performance is far less than metal and glass containers.

Multilayer co-extruded barrier sheets are here to stay

Therefore, in order to meet the packaging industry's demand for high-performance plastic packaging materials, multilayer co-extruded barrier sheet was born. By cleverly co-extruding different types of plastic raw materials for multi-layer composite, you can give full play to the unique properties of each material, the advantages of a variety of resins into one, so as to comprehensively enhance the comprehensive performance of packaging products. This multilayer composite sheet not only has excellent barrier properties, can effectively protect the goods from the external environment, but also has excellent mechanical strength and heat and cold resistance, to ensure that the packaging products in a variety of harsh environments can maintain stable performance. At the same time, its good printing adaptability and non-toxic and harmless properties also make it become the preferred material in many packaging areas.

Wide range of applications for multilayer co-extruded barrier sheets

Multi-layer co-extruded barrier sheets are used in a wide range of applications covering food, pharmaceuticals, electronic products, daily necessities, cosmetics and many other fields.

In food packaging, it can be used to protect perishable foods such as fresh fruits and vegetables, meat, dairy products, etc. and extend their shelf life;

In pharmaceutical packaging, it prevents drugs from becoming ineffective due to moisture, oxidation or exposure to light;

In the packaging of cosmetics, it can effectively prevent the invasion of microorganisms and provide a sterile packaging environment. Improve the aesthetics of the packaging and increase its practicality, such as easy to carry and easy to open.

JWELL PP/PE/PA/PETG/EVOH Multilayer Barrier Sheet Co-extrusion Line

In the modern packaging industry, material selection and innovation are key drivers for the industry. As consumers become increasingly concerned about the safety, shelf life and environmental performance of their goods, the functionality and sustainability of packaging materials are at the centre of market attention. Against this backdrop, multilayer co-extruded barrier sheets are rapidly emerging as a new favourite in the packaging sector due to their unique performance advantages.

The PP/PE/PA/PETG/EVOH Multilayer Barrier Sheet Co-extrusion Line from JWELL https://www.jwellmech.com/PP-PE-PA-PS-PETG-EVOH-EVA-Multilayer-Barrier-Sheet-Co-extrusion-Line-pd525666398.htmlis a multi-layer structured sheet formed by simultaneous extrusion of plastic raw materials with different properties in a certain order and ratio. This technology enables precise control of the thickness and composition of each layer to achieve the best combination of properties. With multilayer co-extrusion technology, raw materials such as PP, PE, PA, PETG and EVOH can be skilfully combined to form multilayer co-extruded barrier sheets with excellent barrier properties, mechanical properties and appearance. Each layer assumes a specific function, such as blocking gases, water vapour, light, etc., or providing mechanical strength, heat and cold resistance. By precisely designing the structure and material of each layer, it is possible to achieve a high degree of customisation of packaging performance to meet the packaging needs of a wide range of goods.

Application: EVOH material has good barrier properties. Through co-extrusion technology with PP, PE, PA, PETG and other  materials, it can be processed into 5-layer, 7-layer, and 9-layer high-barrier lightweight packaging materials, mainly used in  aseptic packaging, jelly drinks , dairy products, chilled fish and meat products packaging etc. In the non-food aspect, it is used  in pharmaceutical, volatile solvent packaging and other fields, with excellent barrier properties, which greatly improves the  shelf life of products.
