Current situation and future of plastic packaging materials

consumers have a mixture of love and hate for 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

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, plastic has successfully replaced most other materials, among which the separator polypropylene is particularly prominent. Processors, such as RPC company, add vinyl acetate layer into transparent polypropylene, 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 this kind of packaging by the industry giant dole is another successful case of contradictory marketing strategy.) Compared with long-term fresh-keeping tin packaging, in addition to the price being 50% higher or higher, the use of this kind of plastic packaging has been welcomed by everyone. At present, the market has an increase of 3-4%

Vince Dean, sales manager of metal stretching field of RPC Corby company, 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 clapboard polypropylene cannot 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 plagued by some children's soft drink markets, so Dean believes that the potential market for plastic packaged fruits in the field of sales 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 been using 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 this problem is. 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 partition packaging can be developed, and no one in the industry can underestimate this possibility, but bottle and can manufacturers don't need to panic at the moment. John Hayes, President of Ball Packaging Europe, predicted that pet could not do much for those consumers who knew beer. Peter Davis, chairman of the British Plastics Federation, expressed different views. In Britain, the long-awaited beer bottle revolution, that is, rigid plastic instead of glass bottles, has not yet happened, but this does not mean that it will not happen. Police and waste organizations hope that alcohol drunk at sports parties and outdoor activities is packaged in plastic bottles

other countries have already done so. In Denmark, Carlsberg beer company has built 10 The function of traversing the curve point by point: the click force and deformation value on the curve can establish a reusable beer bottle industry chain. Customers can get a corresponding refund after returning this wine 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 bulk fruits in the market, he admitted. But if you don't pack these fresh fruits, they won't be fresh for long. The demand for baskets and trays for packaging these fresh fruits will further increase, but the materials used are non environmentally friendly

like other rigid plastic processors, linpac also recognizes the need to supply biodegradable polymers to its customers. But as Barnett quickly admitted, there are potential defects in 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 through the integration of polymer raw materials and post consumer recycling in the primary and secondary packaging industries, processors, brands and retailers can establish a truly closed cycle supply chain

there are many other examples of rigid plastic growth, many of which are small-scale applications. For example, linfreeze series of hybrid polymers launched by linpac a few months ago are supplied to some enterprises that need ultra-low temperature freezing in the dry goods industry. The original purpose of the development of hybrid polymers is to supply frozen food customers in the UK. It can remain 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 special material looks very similar to glass, but it does not have the disadvantage of fragile glass. 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 and becomes garbage, it is difficult 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 another competition funded by the UK waste and resource action plan (wrap) and similar organizations and supply chain partners. Some pet and HDPE waste recycling projects are currently 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 are not opposed to recycled products. For example, only a few 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 plastic 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 increasingly stringent
