Plastic bottle / plastic packaging materials, energy market trends
The 21st century is the century of environmental protection, environmental issues become increasingly important as more strained resources and energy to build a recycling economy and society, take the road of sustainable development has become the focus of global concern and urgent tasks, and become a business strategy and guidelines for human activities. In order to meet the new demands of the times, in addition to plastic packaging materials can meet the market requirements for packaging such as increasing the quality and quantity requirements, its development must be to save resources, save energy, easily recycled after use, easy to dispose of or easy to eliminate the environment satisfied or degradation of the starting point for technology development. China's plastics industry has entered the era of energy-saving environmental protection, plastic packaging materials, new processes, new technologies, new products are emerging, and the positive high-performance, multi-functional, active use of new materials, new technology, broaden application areas as well as plastic packaging and coordinated development of environmentally friendly direction.
Development of circular economy is to build a resource-saving and environment-friendly society and an important way to achieve sustainable development. Saving both adhere to the development, conservation priority, according to reduction, reuse and recycle principles, vigorously promote energy and water conservation and land and materials, enhancing resource utilization, improve renewable resource recycling system, the full implementation of clean production, the formation of low-input , low consumption, low emissions and high efficiency of conservation-oriented growth. Actively develop and promote resource conservation, substitution and recycling technologies, accelerate the pace of energy-saving technological transformation, for consumption, heavy pollution, the technology behind the implementation of mandatory processes and products out of the system is conducive to the implementation of pricing and taxation of resource conservation policy.
High impedance and permeability of plastic packaging materials, because they can give good quality, freshness, flavor and extend shelf life protection function by rapid development and wide application, in addition to the widely used polyvinylidene chloride (PVDC), ethylene vinyl alcohol copolymer (EVOH), in recent years, development of environmentally appropriate materials to promote the polyvinyl alcohol (PVA), polyethylene terephthalate (PEN), a total of polyamide (MXD6), silicon or aluminum oxide film steamed (soft glass), the development of nano-inorganic materials will be more noticeable.
Functional packaging materials, such as functional preservation of film, sheet, microporous breathable film preservation, selective permeability packaging films, shrink packaging films as well as multi-functional with special features, convenience (easy to Kaifeng, easy to re-seal) packaging materials and products, etc. will be greater development. Aseptic packaging materials and technology the biggest advantage is in sterile conditions, without preservatives, without refrigeration, can maximize the retention of the original nutrients of food and flavor, can greatly extend the shelf life, easy storage and transportation, market development very rapidly, expanding use, except in dairy products, fruit drinks account for sweat a larger share, but will be further extended to pharmaceuticals, cosmetics and spices area.
Nanocomposite packaging materials will vary with the rapid development of nanotechnology, and rapid industrialization, due to its wear resistance, hardness, strength, permeability resistance, plasticity were significantly enhanced and improved, except for food packaging, but also for special packaging such as anti-static, electromagnetic, explosion-proof and invisible, dangerous goods packaging, which is expected to promote the traditional plastic packaging materials, a tremendous change.
Environmentally friendly (green adaptive) plastic packaging materials (or green plastic packaging materials), environmental management standards ISl4000 series with the implementation of a global focus of attention, which is easy to recycle plastic packaging materials such as PET, PEN, easy to environmental degradation Plastic (EDP) in biodegradable plastics, but also become a hot spot in the hot, the other as zero pollution foam, thin-walled bottle and pouch packaging containers are also of concern.
Heat canned plastic bottles of juice and tea drinks packaging, aseptic packaging with the traditional, three metal cans, glass bottles compared with lower cost, transparent material, light weight, unbreakable, and good environmental adaptability advantages, has been more widely used, its use accounts for the entire city of more than half of canned heat. PET plastic bottles in addition to canned heat, but in recent years, BOPP bottles are subject to greater attention. BOPP bottle has the following advantages: improved heat resistance is through the drawing process PP, canned temperature can be increased to 100 degrees Celsius, the bottle does not require special equipment to deal with, and to greatly improve the oxygen barrier properties: BOPP bottles do not absorb moisture, longer shelf life, easy recovery: PET bottle products cheaper than the cost of more than 20%. |
