The invention of plastic has brought great convenience to human production and life. At the same time, its pollution problem cannot be ignored. According to the European Plastics Manufacturers Association, from 2015 to 2020, the global plastic production and consumption increased steadily at an average rate of 2% per year, reaching 367 million tons in 2020, and it is expected that by 2035, plastic production will increase Doubling, production will triple by 2050. By then, the global annual per capita plastic consumption will reach 84.37 kilograms.
China is also facing serious plastic pollution problems. With the changes in people's consumption patterns and the rapid development of emerging fields in recent years, , China's plastic consumption reached 90.877 million tons only in 2020 , a year-on-year increase of 12.2%. Once discarded and lost to the natural environment such as soil and water, plastics are difficult to degrade, causing various environmental damage such as soil and water pollution. Improper disposal methods will also affect greenhouse gas emissions and bring lasting harm to the fragile ecological environment. . The entry of microplastics into the food chain may also cause serious harm to human health.
Polylactic acid (PLA) film is a new type of biodegradable material, which is completely degraded by microorganisms in nature under specific conditions, and finally generates carbon dioxide and water, which does not pollute the environment and is recognized as an environmentally friendly material. In addition to the basic characteristics of biodegradable plastics, PLA also has its own unique characteristics: its mechanical and physical properties are good, and strength, transparency and resistance to climate change are much stronger than traditional biodegradable plastics. The polylactic acid film (BOPLA) produced by the biaxial stretching process has better performance comparable to most traditional plastic packaging materials.
Foshan Cailong metallic Packaging Material Co.,Ltd uses advanced coating technology to produce BOPLA coating, which greatly improves the oxygen and water vapor barrier performance of BOPLA, making BOPLA widely used in the packaging field. The following are the characteristics and technical indicators of BOPLA coating produced by Cailong , for the reference of the majority of people who are interested in the packaging design of degradable materials:
Common substrate thickness 20μm～40μm, width and length can be customized.
Polylactic acid (PLA) film is a new type of biodegradable material. It is completely degraded by microorganisms in nature under specific conditions, and finally generates carbon dioxide and water, which does not pollute the environment and is recognized as an environmentally friendly material.
●Polylactic acid (PLA) film has good mechanical and physical properties, good tensile strength and ductility.
● Good gloss and transparency, with the same printing performance as traditional film.
●PLA is the only biodegradable plastic with excellent antibacterial and antifungal properties.
●Environmentally friendly materials, replacing non-degradable plastic films;
