Current situation and future of plastic packaging materials

Huicong Chemical News: consumers love and hate the current packaging materials, especially plastics. In the eyes of some people, rigid plastic packaging is safe and easy to use, while in the eyes of others, it wastes raw materials and pollutes the environment

it integrates the functions of measurement, control, calculation and storage. Although plastic has won again and again in new markets with new styles, it is not so popular in the minds of consumers; Even in some packaging industries, it is still regarded as a bad material

in the field of mainstream packaging materials, plastics have successfully replaced most other materials, among which the separator polypropylene is particularly prominent. Processors, such as RPC company, affect the color of finishing paint in transparent polymer; 2. The ethylene acetic acid layer is added into the stressed propylene, and the packaging material can be used in the field of long-term fruit preservation. Although this product also has some performance defects. (the adoption of such packaging by the industry giant dole is another successful case of contradictory marketing strategy.) Compared with the long-term fresh-keeping iron can packaging, the use of this kind of plastic packaging is welcomed by everyone except that the price is 50% or more higher. At present, the market is growing by 3-4%

Vince Dean, marketing manager of RPC Corby, asked: plastic packaging is more difficult to recycle than iron can packaging, but why do people prefer to buy plastic cans? He should also add that the shelf life of plastic packaging is also very short, because even polypropylene clapboard can not extend the shelf life to more than two years. The answer is that many consumers think plastic packaging is safe and easy to use, and associate it with freshness and health. They can see the products inside through the packaging without worrying about being as fragile as glass, which is deeply loved by customers

the problem of food health has been puzzling some children's soft drink markets. Therefore, Dean believes that the potential market of plastic packaged fruits in the sales field is huge. At present, the partition structure products with the same structure have established a solid foundation in the field of salad and fast food packaging. The beverage industry, especially the beer industry, has always used glass and metal as its packaging materials, but plastic packaging has entered this field on a large scale. It is the cost and performance that affect the choice of packaging in the beer industry, rather than the environmental problems

advocates of glass and metal packaging point out that pet is degraded after being exposed to sunlight and oxygen. The smaller the size of plastic packaging, the more prominent the problem of roller peeling experiment. This means that in Western Europe, where small bottle packaging is popular, consumers either endure a short shelf life or wait for expensive partition packaging solutions

of course, more effective and cheaper clapboard packaging can be developed. No one in the industry can underestimate this possibility, but bottle and can manufacturers need not panic at present. John Hayes, President of Ball Packaging Europe, predicted that pet could not achieve much for those consumers who understand beer. Peter Davis, chairman of the British Plastics Federation, expressed different views. In Britain, the long-awaited beer bottle revolution, that is, the replacement of glass bottles with rigid plastics, has not yet taken place, but this does not mean that it will not happen. Police and waste organizations hope that drinks at sports parties and outdoor activities are packaged in plastic bottles

other countries have already done so. In Denmark, Carlsberg beer has established a reusable beer bottle industry chain. Customers can get a refund after returning the bottle. Recycled beer bottles are refilled with beer after industrial cleaning

in this way, retailers follow the choices of consumers with a confused attitude towards plastic packaging. Adam Barnett, marketing manager of linpac plastics, analyzed the conflict between environment and interests: the current bulk fruits and vegetables sold in retail stores. There has always been a demand for fruit in bulk, he admitted. But if you don't pack these fresh fruits, then it won't be fresh for too long. The demand for baskets and trays for packaging these fresh fruits will further increase, but the materials used are not environmentally friendly

like other rigid plastic processors, linpac recognizes the need to supply biodegradable polymers to its customers. But as Barnett quickly admitted, there are potential defects in the new materials from the perspective of the company as a recycler. He explained: we can supply polylactide, but polylactide in the waste stream will seriously damage our recycling area. Linpac may focus on providing r-fresh products and adding food grade recyclable pet. Barnett believes that processors, brands and retailers can establish a real closed-loop supply chain through the integration of polymer raw materials in the primary and secondary packaging industries and post consumer recycling

there are many other examples of rigid plastic growth, many of which are small-scale applications. For example, linfreeze series hybrid polymers launched by linpac a few months ago are supplied to some enterprises in the dry goods industry that need ultra-low temperature freezing. The original purpose of the development of hybrid polymers is to supply frozen food customers in the UK. It can still keep normal at a low temperature of - 40 C

in another field, as a typical example, Surlyn supplies a special plastic, which changes the current cosmetics and personal care product packaging market. This particular material looks very similar to glass, but it doesn't have the disadvantage that glass is fragile. However, Beaute France, a subsidiary of RPC, pointed out that it also has some special effects and colors, such as multi-color co injection molding, over molding and electroplating

however, once plastic is no longer packaging but garbage, it is hard for users to think of it as a superhero. If the problem of plastic packaging waste is not so serious today, the industry will enter a competition funded by the UK waste and resources action plan (wrap) and similar organizations and supply chain partners. Some pet and HDPE waste recycling projects are progressing smoothly, and the waste treatment capacity after completion will reach the previously promised capacity

according to Paul Davidson, technical manager of plastics, wrap also collects reports indicating that consumers do not object to recycled products. For example, only a small number of consumers are concerned about the PCR content of baby food packaging. But most importantly, wrap's report confirmed that the recycled material content of plastic packaging is likely to have a cumulative impact in further recycling. Davidson believes that in the long run, glass containers are regarded as environmentally friendly products because they are easy to be recycled, but plastics can solve those shortcomings and eventually replace glass. No matter what standard is used, in terms of performance or aesthetics, plastics will eventually be proved to be able to defeat traditional packaging materials. However, the requirements for environmental protection have become more and more stringent
