Biaxially oriented polypropylene film production continues to increase, and the industry has huge development potential
Biaxially oriented polypropylene film (BOPP film for short) is an excellent transparent flexible packaging material. It is made from polypropylene particles that are co-extruded into sheets and then stretched in both vertical and horizontal directions. Biaxially oriented polypropylene film has the advantages of high physical and mechanical strength, light weight, non-toxicity, moisture-proof, wide range of use and stable performance. According to different uses, biaxially oriented polypropylene films can be divided into heat sealing films, label films, matt films, ordinary films and capacitor films.
According to the “2022-2027 China Biaxially Oriented Polypropylene Film Industry Application Market Demand and Development Opportunities Research Report released by the Industrial Research Center 》 shows that polypropylene is an important raw material for biaxially oriented polypropylene film. Polypropylene is a thermoplastic synthetic resin with excellent properties. It has the advantages of good dimensional stability, high heat resistance, and good electrical insulation. It is in high demand in the packaging field. In 2021, my country’s polypropylene (PP) output reached 29.143 million tons, a year-on-year increase of 10.2%. Benefiting from the sufficient supply of raw materials, my country’s biaxially oriented polypropylene film industry has developed rapidly and output has continued to increase. According to data from the National Bureau of Statistics, my country’s biaxially oriented polypropylene film output reached 4.076 million tons in 2021, a year-on-year increase of 8.7%.
The production methods of biaxially oriented polypropylene film include tube film method and flat film method. Due to the uneven quality and low efficiency of products produced using the tube-membrane method, it has been gradually eliminated by major companies. The flat film method can be subdivided into simultaneous biaxial stretching method and stepwise biaxial stretching method. The process flow of the stepwise biaxial stretching method is raw material→extrusion→casting→longitudinal stretching→trimming→corona treatment→rewinding→large film roll→aging→slitting→finished product. At present, the gradual biaxial stretching method is adopted by most companies due to its advantages such as mature technology, high production efficiency, and suitability for mass production.
Biaxially oriented polypropylene film is widely used in packaging materials such as clothing, food, medicine, printing, tobacco and alcohol. At present, biaxially oriented polypropylene film has gradually replaced ordinary packaging films such as polyethylene (PE), polypropylene (PP), and polyvinyl chloride (PVC). my country is the world’s second largest packaging country, and packaging demand continues to grow. According to statistics from the China Packaging Federation, the cumulative revenue of enterprises above designated size in my country’s packaging industry will reach 1.20418 billion yuan in 2021, a year-on-year increase of 16.4%. With the rapid development of my country’s packaging industry, biaxially oriented polypropylene film will have broad market prospects as an important packaging material.
Industry analysts said that my country’s biaxially oriented polypropylene film industry has great development potential due to sufficient supply of raw materials and high maturity of production technology. huge. The rapid development of the packaging industry will drive the further expansion of my country’s biaxially oriented polypropylene film market. As the concept of green consumption continues to deepen, consumers’ requirements for the quality of packaging materials will further increase, and energy-saving and environmentally friendly biaxially oriented polypropylene films will become the mainstream of the market.
