Smart plastic bottles change color when water expires

A company called Braskem in Brazil has successfully developed a plastic bottle that identifies whether the water has expired or not through color change on the bottle cap.

According to Science Alert, Braskem, a Brazilian plastic and chemical company, has successfully created a plastic, beverage container that can change colors based on the response to changing internal pH levels. Signs of pH change suggest that products may have been damaged due to expiry date.

Simulate the color transfer process of the bottle cap when the inner component expires.

Although this technology has been in many forms for several decades, Braskem is a pioneer and has certain advantages when developing this technology.

Andrew Manly, communications director of the Packaging Industry Association (AIPIA) said: "Braskem has many advantages in scale and is well known in this particular field with good quality products".

Plastic and chemical company worth $ 7 billion Braskem is one of the manufacturers of materials for making bottles, bottles, reusable containers, cosmetic packaging, . the largest in America. Braskem has many manufacturing plants located in Brazil, USA, Mexico and Germany.

Signs of pH change suggest that products may have been damaged due to expiry date.

The idea for this special plastic technology comes from Brazil, the country recently involved in many food safety scandals, including those at a food company that bribed government inspectors to consumption of rotting flesh and salmonella contamination in the market.

Patrick Teyssonneyre, director of technology and creativity at Braskem, said: "In many countries, we find that contaminated food, food packages are not wrapped well, food is contaminated in the country. production process, transportation and even in the supermarket ".

Meanwhile, many users continue to confuse the date of sale and rely on smelling to assess whether the quality of the food is still usable. In fact, just by feeling it is difficult to determine whether food ensures food safety and hygiene.

However, to reach more customers, Braskem will need to know how to work with food manufacturers and retailers to ensure the most convenient distribution.

The production process for special resins has the ability to detect an expired internal product.

Another issue also needs attention, which is the cost. According to Meghan Stasz, senior director of the Association of Grocery Producers, the cost issue will be an important challenge for Braskem if the company continues to produce these special plastic boxes.

Braskem said that production costs could be reduced somewhat if the technology is widely accepted in the future. Above all, Braskem believes they can provide a cost-effective, competitive solution, especially when compared to the benefits offered to consumers.

Braskem can even persuade Braskem's plastic food manufacturers to choose from many different benefits besides finding out whether they are overdue. For example, with this technology, consumers can avoid defective products, containing harmful ingredients that are harmful to users' health.

With this technology, consumers can avoid defective products.

It is known that the company has started researching this plastic technology since 2013 and first launched the prototype in 2015. Braskem still needs extensive testing to ensure that the plastic production technology can meet all requirements. safety standard.

In addition, Braskem also needs to understand how indicators beyond the specified pH level will affect manufacturers and retailers, while helping consumers understand safety limits. .

The company hopes to find a potential partner and deploy distribution of this smart plastic product to stores in the next two or three years.
