Now social environment problem has become increasingly important, energy resources more nervous and construct circular economy society, to create a harmonious society, sustainable development has become a global focus and urgent task, and become the norm in all walks of life development and human activities. In order to adapt to the demands of a new age, plastic packaging materials in addition to the requirements to meet the market of packaging of quality and quantity is increasing day by day, its development must be to save resources, save energy, after use easy to recycle, or easy to be easy environment given or degradation as the starting point of technology development. Plastic industry in China has been into the era of energy conservation and environmental protection, plastic packing new material, new craft, new technology, new products constantly emerging, and are high performance, multi-function, the active adoption of new materials, new technologies, broadening the application field and development direction, such as the coordinated development of plastic packaging and environmental protection.
Developing circular economy is an important way to build a resource-conserving, environment-friendly society and realize sustainable development. Insist on developing and saving, saving priority, according to the principle of reduction, reuse, recycling, vigorously promote energy conservation water in rhythmic materials, strengthening comprehensive utilization of resources, improve the renewable resources recycling system, fully implementing clean production, low input, low consumption, low emissions and high efficiency of economical growth way. Actively develop and promote resource conservation, substitution and recycling technology, accelerate the technological transformation of energy saving and consumption reducing of enterprises, technology of high consumption, heavy pollution, backward technology and product implement compulsory elimination system, favorable to the price of resource saving and the fiscal and taxation policies.
High resistance and permeability of plastic packaging materials, can be endowed with good quality, fresh, flavor and prolong shelf life function and obtained rapid development and wide application, in addition to the currently widely used of poly (vinylidene chloride (PVDC), ethylene vinyl alcohol copolymer (EVOH), in recent years, the development environmental protection eligibility material, prompting polyvinyl alcohol (PVA) and polyethylene terephthalate (PEN), polyamide (MXD6), silicon or aluminum oxide film (soft glass), the development of nano inorganic materials will be more remarkable.
Functional packaging materials, such as functional preservation film, sheet, microporous breathable fresh-keeping film, choice through the sexual packaging film, multifunctional heat shrink packaging film and special function, convenience, easy open sealable, easy to seal), such as packaging materials and products will have a bigger development. Aseptic packaging materials and technology biggest advantage is under aseptic conditions, no preservatives, no food cold storage, can maximum limit retained the original nutrition and flavor, can significantly extend the shelf life, convenient storage and transportation, market development is very rapid, use continuously expanded, in addition to has set up a file in the dairy products, fruit drinks accounted for a larger share, will further expand the field of pharmaceuticals, cosmetics and spice.
Nano packaging materials will be along with the rapid development of nanotechnology and rapid industrialization, due to its wear resistance, hardness, strength, permeability resistance, are enhanced obviously and improve the plasticity, except for food packaging, can also be used for special packaging such as anti-static, electromagnetic, explosion-proof and stealth, dangerous goods packaging, etc., it is expected to prompt the traditional plastic packaging materials produce a great change.
Environmentally friendly (green eligibility) plastic packaging materials (or green plastic packaging materials), as the implementation of environmental management standards ISl4000 series is becoming a hot spot of global concern, including easy recycling of plastic packaging materials such as PET, PEN, easy environment degradable plastics (EDP) of biodegradable plastic, more become hot spot in the hot, other such as foam, thin wall and zero pollution of bag packaging container also has attracted much attention.
Hot canned plastic bottles of juice and tea beverage packaging, with the traditional sterile paper, three pieces of metal cans, glass bottles packaging compared with low cost and material of the transparent, light weight, not easy damaged, as well as good environmental adaptability, therefore has gained more and more widely used, its consumption accounts for more than half of the entire heat canned city. In recent years, BOPP bottles have received a lot of attention in addition to PET. BOPP bottles has the following advantages: the improvement of heat resistance is made by PP tensile technique, canned temperature can increase to 100 degrees Celsius, bottle does not need special processing equipment, and makes the oxygen resistance performance is greatly improved: BOPP bottles don't absorption of moisture, storage period is longer, easy recycling: the product cost is much cheaper than PET bottle by more than 20%.
