In the past year, there are many bright spots in the plastic packaging industry that deserve attention: the process of lightweight packaging continues to advance and has achieved good results; functional plastic packaging is emerging, and some functional plastic foods with high barrier, cooking resistance, oxidation resistance, etc. Packaging has been rapidly promoted; bio-based plastic packaging is no longer out of reach, and the situation of "thunder and heavy rain" has been reversed; in-mold labeling packaging has become active again, setting off a small climax in the plastic packaging market; convenience has become An indispensable and important part of packaging, more and more companies are increasingly interested in the convenience of packaging ...
These changes are just the beginning. Entering the new year, the author conducted a comprehensive scan of the packaging trends in 2014 and counted the five hot trends in the field of plastic packaging technology.
Keywords: lightweight packaging
Lightweight is a commonly used industrial vocabulary used to describe the practice of reducing the weight of packaging by using less material to produce. Lightweight materials are increasingly favored in the field of plastic packaging, and almost every type of plastic packaging emphasizes this in shape and structure. There are many challenges to reduce the weight and thickness of packaging materials. The lightweight packaging needs to maintain the performance and function of the original packaging, which is a major test for the production technology of lightweight packaging materials. In the past few years, through a series of material innovations and technological advancements, lightweight packaging has made great progress. In 2013, Sidel launched a new 0.5-liter PET bottle called RightWeight, weighing only 7.95 grams. Compared with the current 0.5-liter water bottle with an average weight of 12 grams, the weight of the bottle is reduced by as much as 34%.
In fact, the reason why lightweight packaging can get a positive response from most companies is not only environmental protection, but also because lightweight packaging allows companies to use less packaging materials and directly save a lot of costs. Therefore, in the future, as the price of raw materials rises, the value of lightweight packaging for enterprises will become increasingly prominent. Lightweight packaging in 2014 is still the biggest development direction of plastic packaging.
Keywords: functional film
In recent years, the plastic film market is gaining momentum, showing a significantly higher growth trend than traditional packaging materials such as paper packaging, cardboard, and aluminum foil. At the same time, while the packaging film is thinning, the functionality is stronger, which promotes a higher rate of growth in this market. In such a fast-growing market, more and more companies will invest in the upsurge of functional films in 2014, which can accelerate technological innovation and promote the continuous emergence of new products.
Functional film is one of the most promising application fields in the development of new packaging technology. Plastic packaging films with high barrier properties, high-temperature cooking resistance, low-temperature freezing resistance, active packaging, heat-shrinkable films, baking resistance, and antibacterial properties have become the focus of market development. Especially in terms of barrier properties, the high barrier film will become the focus of corporate R & D in 2014 due to its excellent barrier performance, which plays a role in the preservation of food, preservation of freshness and the extension of the life of goods.
The new transparent high-barrier film that has been launched is gradually narrowing the distance from aluminum foil and metallized film. The new film can not only provide a good display effect for the contents, but also avoid the problems such as cracking after the aluminum foil and the traditional metal-plated film are bent.
Keywords: bio-based plastics
As we all know, oil is a scarce and non-renewable resource. The imbalance of oil resources in various countries and the predatory exploitation of developed countries have become an important factor in the unrest of the world. Therefore, developing biodegradable materials and reducing the consumption of petrochemical resources have gradually become the consensus of all countries in the world, especially developed countries. In recent years, related technologies have developed very rapidly, and more and more bioplastics have appeared in the packaging field.
In 2013, Coca-Cola's plant environmental protection bottles began to be listed in China. This is the world's first plant-based PET packaging for large-scale commercial applications. Compared with traditional PET plastic bottles that completely rely on petroleum, plant environmental protection bottles reduce the dependence on non-renewable resources and reduce carbon emissions.
Huawei, a well-known IT manufacturer in China, has also initiated application research on the first use of bio-based cushioning pads and film bags in the packaging of terminal equipment, and has achieved staged results. Bio-based plastics have brought new light to the sustainable development of the plastic packaging market. Although Biodegradable Packaging currently accounts for only a small portion, the market share of bio-based plastic packaging will continue to grow in the future.
Keywords: In-mold labeling packaging
In-mold labeling technology has been introduced into China's plastic packaging market as early as 10 years ago, and has caused a lot of sensation in the industry. However, due to various factors, it has not been able to achieve breakthrough development in China, and its market share is still very small. The good news is that the domestic in-mold labeling packaging market, which has been covered by "hard ice" for many years in the past two years, has begun to re-activate, and has set off a small upsurge in the plastic packaging market. Especially in the field of FMCG packaging, under the pressure of rising labor costs, the number of FMCG companies surveying and adopting in-mold labeling packaging technology in the market is no small.
In-mold labeling packaging adopts the processing method of container forming and labeling at one time, eliminating the link of labeling, and has obvious advantages in saving labor costs. In the current general environment in which production enterprises are difficult to work and labor costs are rising, more enterprises will adopt in-mold labeling and packaging in 2014.
Keywords: convenience packaging
In the past, packaging has done its homework in shelf display, protection, and convenient transportation, but it still lacks in packaging convenience. Nowadays, with the improvement of living standards and the acceleration of social rhythm, consumers' requirements for packaging continue to increase, thereby promoting the innovation and development of packaging in convenience. In the past, many plastic packages had to be opened with the aid of teeth or scissors, but now most of these packages have more convenient and quicker opening methods.
The emergence of new sealing technologies such as resealable zippers and screw caps on flexible liquid packaging bags helps consumers to open packages without tearing any bag heads. In addition, the latest convenient packaging can also realize self-heating, direct microwave heating, cooking resistance, automatic cooling and other functions. In 2014, convenience packaging is no longer an optional option, and more companies will consider the convenience of packaging.
In summary, in 2014, the plastic packaging industry will focus on the five major areas of lightweight packaging, functional films, bio-based plastics, in-mold labeling packaging, and convenience packaging, and they are not independent, but a closely linked overall. 2014 has arrived, and the technology has also developed rapidly. It is believed that more innovative and environmentally friendly plastic packaging products will emerge this year.
