The market size of multi-layer co-extruded films continues to grow. There are many manufacturers in my country

Multi-layer co-extruded film refers to a film in which a variety of plastic raw materials are divided into many channels and extruded from a die at the same time. Multi-layer co-extruded films have the advantages of good mechanical properties, good heat sealing performance, good barrier properties, high oxygen resistance, high/low temperature resistance, etc., and are widely used in daily chemicals, medicine, food processing, electronic products, agriculture and other fields.

Multi-layer co-extruded films are usually made of a three-layer structure of adhesive layer, base layer and functional layer. The adhesive layer is located between the base layer and the functional layer to play a bonding role. Ethylene-vinyl acetate copolymer (EVA) and maleic anhydride grafted polyolefin are its main raw materials; the base layer is usually made of PET, EVA, PP and PE. It is made of polymer materials such as polyvinylidene chloride (PVDC), ethylene-vinyl alcohol copolymer (EVOH), etc. and plays a decisive role in the comprehensive performance of the multi-layer co-extruded film. be made of.

The top-blowing method and the down-blowing method are the main preparation processes for multi-layer co-extruded films. The up-blowing method has the advantages of good finished product quality, low production cost, and high technological maturity. It is the mainstream preparation method for multi-layer co-extruded films, but its production capacity is low and the product is only suitable for small packaging; the down-blowing method can be used to prepare high-stretch films. High-efficiency, high-transparency food-grade multi-layer co-extruded film. However, this method currently has problems such as high production costs and high equipment requirements, and has not yet been applied on a large scale. In the future, with technological advancement, my country’s multi-layer co-extruded film production capacity and output are expected to increase.

As a packaging material, multi-layer co-extruded film has a wide range of applications. Daily chemicals, medicine, food processing, electronic products, agriculture and other fields are its main demand ends. In the field of daily chemicals, multi-layer co-extruded films can be used as packaging materials for toothpaste, soap, dishwashing liquid and other products; in the field of food processing, multi-layer co-extruded films can effectively block water and oxygen and can be used to preserve the freshness of meat products. Film; in the pharmaceutical field, multi-layer co-extruded films can be used to produce medical packaging materials such as fluid storage bags and infusion bags. According to the “2023-2028 China Multilayer Co-extruded Film Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center It shows that strong downstream demand has driven the continued growth of my country’s multi-layer co-extruded film market, reaching nearly US$400 million in 2022.

There are many players in my country’s multi-layer co-extruded film market. The main manufacturers include 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. The multi-layer co-extruded films it produces are mainly used as pharmaceutical packaging and food packaging materials.

Industry analysts said 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 manufacturers in my country, and the market competition is fierce. It is expected that in the future, with technological advancement, my country’s multi-layer co-extruded film industry will gradually develop in a high-quality direction.
