Aside from food packaging, one of the most commonly encountered industrial products in people's everyday life is plastic products, particularly plastic bottles. But because of the widespread use of disposable plastic bottles, environmental protection is under considerable strain. As a result, the development of plastic products must be directed toward environmental protection.
Environmental issues are becoming increasingly important in the twenty-first century, and obtaining and conserving resources and energy is becoming increasingly time-intensive. Making the transition to a circular economy and society, as well as the focus of sustainable work, has become a matter of critical importance. It should also be accepted as the norm in order to promote the development of all aspects of human life and activity. Developing plastic packaging materials that are resource-saving, energy-saving, easy-to-recycle after use, and environmentally friendly is essential in order to meet the demands of the new millennium while also meeting the growing market demand for apparel box packaging quality and quantity. Technical development begins with the acceptance or degradation of a state of affairs. New materials, new processes, new technologies, and new plastic packaging products are constantly being developed, with the goal of becoming high-performance and multi-functional in nature. To broaden the range of applications, new raw materials and new technologies are being introduced, while the development of plastic packaging and environmental protection are coexisting.
For their ability to extend shelf life while also maintaining freshness and flavor, high permeability plastic packaging materials have been developed quickly and are widely used. Along with polyvinyl chloride (PVC), ethylene and vinyl alcohol copolymer (EVOH), polyvinyl alcohol (PVA), polyethylene terephthalate (pen), and copolyamide (MXD6) have all been developed into environmental protection materials in recent years. Silicon or alumina membrane (soft glass) will be more prominent in the development of inorganic materials in the coming years.
When metal polyamides (mhdpe, mLLDPE, and MPP) are used in flexible packaging, they can improve a variety of properties such as strength and rigidity. They can also be transparent, provide a barrier, be heat resistant, and be easy to operate. Those in the business community will be both concerned and grateful.
Expand the development of functional packaging materials like films and new films (such as detectable micro growth films), permeable packaging films (such as breathable packaging films), functional packaging films, and custom makeup palette and products with special functions and convenience (such as easy to open and reset). There is a major advantage to using aseptic packaging materials and technology because it eliminates the need for preservatives and refrigeration, allowing food to be preserved for as long as possible while retaining its nutritional components and taste. Shelf life can be significantly extended, and storage, transportation, and market development are made much easier. Its speed is incredible, and its applications are becoming increasingly widespread. The company will continue to expand its presence in a variety of industries, including medicine, cosmetics, and condiments, in addition to dairy products and fruit sweat.
With the rapid advancement of nanotechnology, nanocomposite packaging materials will be introduced in a short period of time. The significant improvement in wear resistance, hardness, strength, barrier and transparency makes them suitable for use as special packaging as well as for food packaging in particular. The traditional plastic packaging materials are expected to undergo significant transformation, much like the packaging of dangerous, electromagnetic, explosion-proof, and invisible goods.
Attracting global attention have been environmentally friendly plastic packaging materials (also known as green plastic packaging materials) and the implementation of the ISO14000 series environmental management system. Among these are biodegradable plastic packaging materials such as pet and pen, which are easily degraded by the natural environment. Real-time points in the life cycle of biodegradable plastics (EDP) in plasticsThere has also been a lot of interest in other things such as uncontaminated foamed plastics, thin walled bottles, and bag-like containers, among others.
Comparing traditional sterile paper packaging, metal three piece cans, and glass bottles for fruit juice and tea beverage packaging, the material costs are lower, the packaging is transparent, the packaging is light weight, the packaging is not easily broken, and the packaging is highly environmentally adaptable. As a result, they have become more widely used, accounting for more than half of the total heating market today. Additionally, BOPP bottles have received a lot of attention in recent years, in addition to the pet in the hot pot phenomenon. Among the advantages of the BOPP bottle are the following: the heat resistance is improved through the PP stretching process, the canning temperature can be increased to 100 degrees Celsius, the bottle mouth does not require special equipment, and the oxygen resistance is greatly improved. When compared to PET bottles, the BOPP bottle is less expensive because it does not absorb moisture, has a longer storage period, and is easy to recycle.
