China's petrochemical equipment manufacturing industry is at a crucial stage of development, with significant investment and demand expected in the coming years. According to estimates from relevant departments, during the "11th Five-Year Plan" period, annual investments in petrochemical equipment are projected to reach 30 billion yuan, with total investments exceeding 150 billion yuan. The demand for petrochemical equipment is estimated at 2.5 million tons, including 700,000 tons of key equipment. Specialized equipment such as reactors, heat exchangers, towers, storage and transportation systems, heaters, and special machinery account for 100,000 tons, requiring an investment of 47.5 billion yuan. The National Development and Reform Commission has identified 28 industries and 526 products and technologies for encouragement, including infrastructure and services. Within the petroleum and petrochemical sector, three major areas have been emphasized: the development of key technologies and equipment for large-scale fertilizer and ethylene plants, the production of large turbine compressors for petrochemical facilities, and the exploration and drilling of oil and gas. As the saying goes, "Heaven does not take, but follows others." China's ambitious development plan for the petroleum and petrochemical industry presents a golden opportunity for its equipment manufacturing sector. However, this opportunity can only be seized by addressing internal shortcomings and securing strong government support. Otherwise, the benefits will flow to foreign manufacturers, leaving domestic companies behind. Despite progress over the past two decades in localizing major petrochemical equipment, the goals outlined in the State Council’s 1983 "Decision on Grasping the Development of Major Technical Equipment" remain unfulfilled. Localization efforts have continued for more than 20 years alongside ongoing technology imports, leading to a widening gap with international competitors. While China ranks fourth or fifth globally in petrochemical equipment output, its overall scale is only one-fifth of the U.S., one-fourth of Japan, and one-third of Germany. With over 500 petrochemical equipment manufacturers, none have achieved global prominence, and the industry still lacks the capability to supply large-scale equipment for major projects. Although the industry is large in size, it remains "big but not strong." A key factor contributing to this weakness is the lack of effective government guidance, which has exacerbated the gap between Chinese and foreign manufacturers. The industry suffers from disorganization, with many small enterprises competing in a limited market. Over 300 companies generate more than 500 million yuan annually in sales, but their fragmented resources and dispersed technological capabilities prevent them from achieving scale. Market limitations and intense competition lead to non-standard practices, particularly in price wars that erode profits. The product structure is also highly similar, with many manufacturers producing the same goods without differentiation. Most equipment is low-end, lacking innovation and intellectual property. For example, while China produces thousands of drilling rigs, most are technologically outdated. Corporate integration has been slow, with state-owned, private, and foreign enterprises coexisting without unified coordination. This lack of consolidation hinders the formation of strong, large-scale enterprises capable of meeting future demands. Without centralized leadership and policy support, the industry cannot fully localize critical equipment or compete effectively. Compared to the petroleum equipment sector, the petrochemical equipment industry faces even greater challenges. Over 60% of petrochemical plant technologies come from abroad, with limited independent innovation. R&D lags behind process technology, and imported equipment is often re-introduced without meaningful adaptation. The industry lacks professionalization, standardization, and long-term R&D centers. Moreover, insufficient policy and financial support for localization creates high risks for manufacturers, dampening enthusiasm and long-term planning. Leadership changes and resource shortages further hinder progress. To revitalize the sector, the government must play a leading role in guiding integration, providing stable policies, and ensuring the security of national economic interests. Only through coordinated efforts can China achieve self-reliance in petrochemical equipment and secure its place in the global market.

PVC Food Grade

PVC sheet is a widely used and popular material. PVC Film can be divided into food grade and industrial grade, and it can be made into transparent, colorful, anti-static, gold-plated, flocking, etc. For vacuum forming, its main characteristics are high transparency, good surface gloss, less crystal points, small water lines, wide use, strong impact resistance, and easy molding. The finished product meets the US FDA and Japanese PL food hygiene standards. It is widely used in the outer packaging of toys, food, electronic products, medicine, electrical appliances, gifts, cosmetics, stationery and other products.

The main classification of blister products
1. If classified according to the thickness of the material, it can be divided into
A. The thickness of ordinary thin blister is 0.14~5.0mm-mainly made of various materials and effects such as PVC, PP, PS (HIPS), PET (including APET and PETG), PE, BOPS and recyclable paper trays Folding, half-folding, three-folding, cylinder, Folding Box, heaven and earth box, high frequency and other non-thermoformed blister products are widely used in food, medicine, electronics, toys, computers, daily necessities, cosmetics, machinery hardware and other industries.
B. The thickness of the special thick blister is 0.14~5.0mm-mainly the plastic injection products with various materials and effects such as PVC, PP, PS (HIPS), PET), ABS, PC, PE, etc.
The reason for not classifying the types of materials is mainly considering that there are some differences between the materials used in ordinary thin blister and special thick blister, but PVC, PP, PS and PET are all in these two types of blister products. To have a role to play!
PVC hard film has moderate toughness and is not easy to burn. It will produce chlorine when burned, which will affect the environment. PVC is easy to heat and can be sealed with a sealing machine and high-frequency machine. It is the main raw material for producing transparent plastic products.
PS hard film has low density, poor toughness, easy to burn, and will produce styrene gas (a harmful gas) when burned, so it is generally used to produce various industrial blister trays.
PET hard film has good toughness, high transparency, easy to burn, and does not produce harmful gas when burned. It is an environmentally friendly material, but the price is high, and it is suitable for high-end blister products. The blister blister in European and American countries generally requires PET hard film, but It is not easy to heat seal, which brings great difficulties to packaging. In order to solve this problem, people compound a layer of PVC film on the surface of PET, named PETG rigid sheet, but the price is higher.
