Growth in market scale of multi-layer co extruded film and increase in production enterprises

Multi layer co extruded film refers to a film formed by simultaneously extruding multiple plastic raw materials into multiple channels from a single die. Multi layer co extruded films have advantages such as good mechanical properties, good heat sealing performance, good barrier properties, high oxygen resistance, and high/low temperature resistance. They are widely used in daily chemical, pharmaceutical, food processing, electronic products, agriculture, and other fields.

Multilayer co extruded films are usually made of a three-layer structure consisting of an adhesive layer, a base layer, and a functional layer. The adhesive layer is located between the base layer and the functional layer, playing a bonding role, with ethylene vinyl acetate copolymer (EVA) and maleic anhydride grafted polyolefin as its main raw materials; The base layer is usually made of polymer materials such as PET, EVA, PP, and PE, which play a decisive role in the comprehensive performance of multi-layer co extruded films; The functional layer, also known as the barrier layer, is usually made from raw materials such as polyvinylidene chloride (PVDC) and ethylene vinyl alcohol copolymer (EVOH).

The top blowing method and bottom blowing method are the main preparation processes for multi-layer co extruded films. The upper blowing method has the advantages of good product quality, low production cost, and high technological maturity, making it the mainstream preparation method for multi-layer co extruded films. However, its production capacity is relatively low, and the product is only suitable for small packaging; The down blowing method can be used to prepare edible grade multi-layer co extruded films with high elongation and transparency. However, currently, this method has high production costs and high equipment requirements, and has not yet achieved large-scale application. In the future, with technological progress, the production capacity and output of multi-layer co extruded films in China are expected to be improved.

As a packaging material, multi-layer co extruded film has a wide range of applications, with daily chemical, pharmaceutical, food processing, electronic products, agriculture and other fields as its main demand end. In the field of daily chemical industry, multi-layer co extruded films can be used as packaging materials for products such as toothpaste, soap, and detergent; In the field of food processing, multi-layer co extruded films can effectively block water and oxygen, and can be used as preservation films for meat products; In the pharmaceutical field, multi-layer co extruded films can be used to produce medical packaging materials such as liquid storage bags and infusion bags. According to the "2023-2028 China Multilayer Co extruded Film Industry Market Deep Research and Development Prospects Prediction Report" released by the Xinsijie Industry Research Center, the strong downstream demand has driven the continuous growth of China's multi-layer co extruded film market, reaching nearly 400 million US dollars in 2022.

There are many participants in the multi-layer co extruded film market in China, with main manufacturers including Huaqiang Technology, Bosheng Medical Materials, Haishun New Materials, Shisiyao Group, Chutian Technology, Jinjia New Materials, etc. Haishun New Materials focuses on the research and development, production, and sales of new high barrier composite materials. Its multi-layer co extruded films are mainly used as pharmaceutical packaging and food packaging materials.

Industry analysts from Xinsijie stated that multi-layer co extruded films, as polymer composite films, have broad application prospects in the packaging field. In terms of market competition, there are many multi-layer co extruded film production enterprises in China, and the market competition is relatively fierce. It is expected that in the future, with technological progress, China's multi-layer co extruded film industry will gradually develop towards high-quality direction.
