1. Product Overview

EVOH High Barrier Sheet Extruder is an advanced equipment specially used for producing EVOH high barrier sheet. In many fields such as modern packaging, food preservation, and medicine, the barrier properties of materials are extremely high, and the EVOH sheets produced by this extruder can effectively meet these requirements.

2. Technical Principle

Precise Extrusion Process

The extruder adopts advanced screw design, which can accurately control the material conveying, plasticization and extrusion process. The structure of the screw has been carefully optimized to ensure that the EVOH resin is evenly heated and fully plasticized during the extrusion process, thereby ensuring the stable quality of the sheet. Through precise temperature control and screw speed adjustment, it can adapt to different production process requirements and produce EVOH high barrier sheets with uniform thickness and consistent performance.

Realization of high barrier performance

EVOH has excellent barrier properties, especially for substances such as oxygen, carbon dioxide and aroma. During the extrusion process, the machine can maintain the integrity of the molecular structure of EVOH, so that its barrier properties can be maximized. At the same time, the extruder can also add other additives or perform multi-layer co-extrusion as needed to further improve the comprehensive barrier properties of the sheet.

3. Equipment Structure and Features

Sturdy and Durable Structure

The main structure of the extruder is made of high-strength metal materials, such as high-quality alloy steel. This structure ensures the stability and reliability of the equipment during long-term, high-intensity production operations. The shell is rust-proofed and can adapt to different production environments, including humid and highly corrosive environments.

Efficient Heating and Cooling System

Equipped with an efficient heating system, it can quickly heat the material to the required extrusion temperature. The heating elements are evenly distributed around the barrel to ensure that the material is heated evenly. At the same time, the cooling system is also very critical, which can take away excess heat in time to prevent the material from overheating and decomposing. The synergy of this heating and cooling system improves production efficiency and reduces energy consumption.

Intelligent Control System

With an intelligent control system, operators can easily set and adjust various parameters such as temperature, pressure, screw speed, etc. through the touch screen. The system also has a fault diagnosis function, which can monitor the operating status of the equipment in real time. Once an abnormal situation occurs, it will issue an alarm and display fault information in time, which is convenient for maintenance personnel to quickly locate and solve the problem.

4. Product application field

Food packaging

In the field of food packaging, the sheets produced by EVOH High Barrier Sheet Extruder are widely used in the packaging of meat, cheese, fruits, vegetables and other foods. It can effectively prevent oxygen from entering the packaging, slow down the oxidation and deterioration process of food, extend the shelf life of food, and maintain the flavor and nutritional content of food.

Pharmaceutical packaging

For pharmaceutical products, high barrier packaging is essential. EVOH sheet can prevent drugs from being damp, oxidized and affected by external pollutants. The sheets produced by the extruder can be used to manufacture sealed packaging for medicine boxes and medicine bottles, etc., to ensure the quality and safety of medicines during storage and transportation.

5. Production efficiency and environmental protection

High output and high quality

The extruder has high production efficiency and can meet the needs of large-scale production. At the same time, due to its precise control and stable performance, the sheets produced are of excellent quality and low scrap rate, thereby improving the economic benefits of the enterprise.

Environmental Advantages

EVOH itself is a relatively environmentally friendly material, and the extruder uses energy-saving technology in the production process to reduce energy waste. In addition, the high barrier sheet produced helps to reduce the waste of food and medicine, etc., and indirectly contributes to environmental protection.

EVOH High Barrier Sheet Extruder is an ideal equipment for modern production of high barrier sheets with its advanced technology, excellent structure and wide application fields, providing strong support for the development of many industries.
