The plastic stretch film industry will be broken

Plastic stretch film and polyolefin shrink film have you ever used it? Or have you seen it? Do you think you've seen it in many areas? So what do you think is going to happen in the future?

The melted or soluble polymer is processed into a soft, uniform, very thin sheet material. The thickness is below 0.25 mm (the thinnest can reach several microns). A sheet with a thickness of more than 0.25 mm is usually called a sheet. Stretch film and polyolefin shrink film for electrical insulation have high mechanical strength, certain elongation, high breakdown strength and thermal insulation resistance, and corresponding heat resistance. The application of stretch film and polyolefin shrink film in electrical engineering has greatly improved the insulation materials. For example, after replacing the yellow wax cloth with polyester film in the insulation of the motor groove, the heat resistance of the insulation is improved and the thickness of the insulation is reduced. In power capacitors, some or all of polypropylene film is used to replace the capacitor paper, which can reduce the volume of capacitors and improve the specific characteristics of capacitors (capacitance per unit volume). The appearance of stretch film and polyolefin shrink film made the heat resistance of insulation structure increase to H grade and above.

As an electrical insulating material, stretch film and polyolefin shrink film need to consider a variety of properties. The main characteristics and evaluation results of films for selection are summarized in the table.

Some stretch film and polyolefin shrink film can be used as insulation material for cryogenic electricians. Such as teflon, polyimide, high-density stretch polyethylene, polyimide, polyamide (nylon 11) film, can be used as the superconducting low temperature insulation materials. In recent years, the rapid development of agriculture, food industry and cosmetics industry in China has greatly promoted the development of packaging industry, thus boosting the advance of stretch film and polyolefin shrink film industry. In 2012, China's plastic film industry achieved a total industrial output value of 219.186 billion yuan and achieved a sales revenue of 217.951 billion yuan, according to data from the "2013-2017 forecast and analysis report on production and sales demand and investment in China's plastic film manufacturing industry" released by the national forward-looking industry research institute. Among them, the plastic packaging industry realized the industrial output value of 147.192 billion yuan and the sales revenue of 146.145 billion yuan, respectively accounting for 67.15% and 67.05% of the industrial output value and sales revenue of stretch film and polyolefin shrink film industry. It can be seen that the development of plastic packaging industry is particularly important to the development of stretch film and polyolefin shrink film industry.

In China, the plastics industry in the '50 s and' 60 s, the rapid development of plastic packaging in the 70 s, is a growth in the early 80 s to 90 s, domestic plastic packaging effect and function of all commodities, there has been a fundamental change since the 90 s, multinational consumer goods companies to enter China in succession, the consumer market demand for plastic packaging more perfect, rapid demand growth, many companies began to expand the scale of investment in the plastic packaging, window transparent film. From the perspective of packaging types, in 2012, China's plastic packaging achieved the total industrial output value of 147.192 billion yuan, and achieved the sales revenue of 146.145 billion yuan. The sales revenue of glass packaging was 553.86 billion yuan. The sales revenue of metal packaging was 107.026 billion yuan. It can be seen that in 2012, China's plastic packaging occupied the main market share of the packaging industry, leading the packaging materials such as glass and metal.

If you think the future of stretch film and polyolefin shrink film is immeasurable, so if you're in the business now, take the opportunity
