“To increase recyclability, save energy and reduce consumption, extend the storage period of nutrients, and broaden the scope of application are the four major trends in the development of polyethylene terephthalate (PET) bottles at this stage. With the help of new additives, it is easy to recycle. PET bottles can replace glass bottles and polyethylene (PE) bottles in more areas; considering the recyclability of materials in advance at the raw material stage can help downstream packaging companies go in this direction.†US Carlos Plastic Colorants (Suzhou) Co., Ltd. General Manager Cai Junxiong said in an interview.
Mr. Cai Junxiong said that the concept of recycling, energy conservation and sustainable development has become more and more popular, and beverage bottle manufacturers are also striving to find such a solution. Some manufacturers are using high performance additives to achieve this effect.
The use of high barrier performance additives is currently an important trend in the world. In the past, the bottle wall had to be made thicker in order to achieve a better barrier effect. Now the barrier performance is improved, and even if the bottle wall is thinner, the effect of protecting the beverage can be achieved. He said that after the drink bottle wall will be very thin, after the drink is finished, the hands can be squeezed with a twist of the bottle, recycling more convenient. Although the purchase of additives adds some cost, the total cost is reduced due to the use of less PET, and it will be helpful for environmental protection. Carlos is now recommending this concept to Chinese customers. This year, Aloesorb and Amosorb SolO2 launched by Glorias are two oxygen absorbers specially designed for the packaging of PET containers for oxygen-sensitive beverages and foods. It is possible to achieve better protection and longer shelf life. s Choice.
Cai Junxiong pointed out that consumers are now demanding more and more nutritional ingredients in beverages. For example, 100 mg of vitamin C is required during the shelf life of beverages. This requires improvement of the bottle and minimizes the loss of nutrients. In addition, milk beverages are generally bottled in PE. The new concept is to use PET bottles that can extend shelf life. Previous milk bottles were made thick to block UV rays, and were usually white PE bottles. The Ultimate UV390 UV absorber exhibited at the Carlsberg facility provides comprehensive and extensive protection for UV-sensitive foods and beverages in plastic products and plastic containers. Lactra is a highly efficient product that enhances the aesthetics of the packaging. Photo-agents, they can achieve the promised shelf life of translucent PET bottled milk, which traditional methods can not do.
It is understood that many European brands have already started cooperation with Carlos and began to use PET bottles extensively. He believes that after the PET has been used in beer packaging, the packaging of red wine, sports drinks, and health products will soon follow, and plastics, a more easily recycled raw material, will be used for glass.
In addition, although the PET material can be recycled many times, once it is used once per cycle, the performance will be degraded; the material will turn yellow after repeated use, and the more times of repeated use, the darker the color. For this reason, PET bottles can only be used retrospectively when they are recycled, and they can be changed from transparent products to non-ferrous product packaging. Cai Junxiong said that in Carlslow's view, any additive must be considered for recycling in the development stage, and for the transparent material to be reused after recycling, it can also be used in transparent products without affecting the appearance and quality of the product. Currently, Carlos is developing some additives to dilute the color of recycled materials.
Cai Junxiong said that in addition to providing packaging material properties, additives can improve the processing performance of plastics to achieve the effect of energy saving. In this regard, Gloria has two main directions: one is the Smart Heat technology that reduces the thermal energy consumption of the process; the other is the Eze technology that improves the machining efficiency and reduces friction during processing. By reducing the processing temperature of the material, energy can be saved on the one hand, and on the other hand, the requirements on the equipment can be reduced. Joule RHB Reheat, Joule RBK Reheat, and Optica Toner heat exchangers developed by Carlos can be added during compounding. In this way, downstream companies do not need to add anything during the injection molding process, which can increase production efficiency.
"We are expanding our Suzhou plant's production capacity and we hope to have the plant's production cover the company's full range of products by 2010," said Cai Junxiong. Following the construction of the first colorant production line in Suzhou in 2008, Carlos's PET resin reinforcing agent and additive product line will be delivered within China this year.
