BOPE does not have a competitive advantage and the current market demand is relatively low.

Biaxially oriented polyethylene film (BOPE) is a polyethylene film product produced by using LLDPE as raw material and using the biaxially oriented step-by-step stretching process of the flat film method. BOPE has the advantages of high transparency, heat sealing performance, and good longitudinal and transverse tensile strength. It can still achieve the performance of other polyethylene films even if its thickness is reduced by 50%. Using BOPE film for packaging can effectively reduce the thickness of plastic packaging and reduce the use of packaging materials. It has the advantages of environmental protection and cost reduction, so the industry has good development prospects.

At present, BOPE film has been developed into application fields such as composite bags, agricultural films, white films, and medium packaging bags. In terms of production, BOPE film production equipment is complex and requires high investment in equipment. Currently, BOPE film equipment in the world is mainly provided by Bruckner Group. In 2017, it proposed a concept production line for the co-production of BOPE and BOPP films. The theoretical output of BOPE film can reach 5 tons/hour, and trial production is being carried out around the world. The industrialization of BOPE film plays a promotional role.

Compared with the development of biaxially oriented films such as PP, PA, and PET, the industrialization of BOPE films lags behind, mainly due to three limitations: First, BOPE films have extremely high requirements for the stretching stability of raw materials. In the absence of special materials, In the context of the use of general-purpose polyethylene and additives, products produced with general-purpose polyethylene have shortcomings such as small stretch ratios and high crystallinity; the second point is the lack of BOPE film processing equipment. In 2017, adopting companies launched equipment dedicated to BOPE film production; The third point is that due to immature technology, the current quality stability of BOPE films is poor and the production cost is high.

According to the “China Biaxially Oriented Polyethylene Film (BOPE) Industry Application Market Demand and Development Opportunities Research Report 2021-2026” released by the Industrial Research Center It shows that in general, the key to restricting the industrialization of BOPE films is the stability of film quality, price difference, unstable supply cycle, low cost performance, etc. Except for a few companies that have mastered the core technology, they can stably supply high quality. Except for BOPE film, most companies still remain on the sidelines. The main purpose of BOPE film production is to replace traditional BOPE, BOPET, BOPA and other products. However, currently, BOPE film lacks cost advantages. The industry is currently in a vicious cycle of inactive application and development and slow commercial scale expansion.

Industry analysts said that BOPE film has excellent performance, a wide range of applications, and good industry development prospects. However, in actual production, due to the slow development of special equipment and materials for BOPE films, and the fact that the core technology of BOPE films is mastered by some companies, most companies do not have the ability to stably produce BOPE films, and most of the products they produce are of poor quality and low cost. High, it does not have the advantage of replacing traditional BOPE, so the market enthusiasm is low. Although BOPE films have made great progress in the packaging field of liquids, quick-frozen foods, chemical products, heavy packaging, etc., overall, the market popularity is low and the industry development risks are high.
