Polylactic acid-- a bio-degradable material helps the green environment protection

Plastic has brought a lot of convenience to our life. Many plastic packagings are used in our clothing, food, housing and transportation.But when it comes to plastic, many people have a common impression -- it's not environmentally friendly.This is because the commonly used petroleum-based plastics are difficult to degrade in the natural environment, and its pollution control is also a worldwide problem.In order to protect the environment we live in together, scientists have put forward the new concept of "originating from nature and returning to nature", and developed synthetic methods of converting corn and other biomass into biodegradable Poly(lactic acid) plastics, which provide feasible solutions to control plastic pollution through the magic of chemistry.

--What is PLA material?

PLA is not plastic material.It also known as polylactic acid,it is similar plastic material made of plant starch. Different from traditional plastics, it comes from renewable resources such as corn starch, which also makes it biousable and decomposable.Most conventional plastics come from the distillation of non-renewable oil and natural gas."Plastics" derived from biomass, such as PLA, are called "PLA biodegradable plastic".

Biodergradable PLA material

--Its advantages:

1.Environmental protection.Polylactic acid (PLA) is a new type of biodegradable material, using renewable plant resources (such as corn) made of starch raw materials.Starch raw materials through saccharification to obtain glucose, and then from the glucose and a certain strain fermentation into high purity lactic acid, and then through chemical synthesis method to synthesize a certain molecular weight of polylactic acid.It has good biodegradability, can be completely degraded by microorganisms in nature after use, and eventually generate carbon dioxide and water, which does not pollute the environment, which is very beneficial to the protection of the environment, and is recognized as an environmentally friendly material.

2. Good mechanical and physical properties.It can be used for all kinds of plastic products, dessertfood packages, fast food lunch boxes, non-woven fabrics, industrial and civil fabrics. It has a unique advantage in disposable tableware, food grade packaging materials and other disposable products.Its ability to fully biodegrade is also in line with the world, especially the European Union, the United States for environmental protection of the high requirements.Our factory has recently produced macaron plastic blister display tray using PLA material, which is very popular with our customers

3. Good compatibility and degradability.Polylactic acid is highly safe for human body and can be absorbed by tissues. Combined with its excellent physical and mechanical properties, polylactic acid can also be used in the field of biomedicine, such as disposable infusion tools non-removable surgical sutures, drug relief packaging agents, artificial fracture internal fixation materials, tissue repair materials, artificial skin, etc.It has been used to replace stainless steel, as a new type of orthopedic internal fixation materials such as bone nails, bone plates and has been widely used. Its characteristics of absorption and metabolism by the human body make patients free from the pain of second operation.Its high added value technology is a promising polymer material in the medical industry.

4.Polylactic acid (PLA) and petrochemical synthetic plastics have similar basic physical properties, that is, it can be widely used to manufacture a variety of applications.Polylactic acid also has excellent gloss and clarity, comparable to films made from polystyrene, which other biodegradable products cannot provide.

The PLA material ushered in a new opportunity for market development. This grain-based plastic realized the environmental protection concept of "originating from nature and belonging to nature", pointing the way to solve the problem of plastic pollution.Perhaps one day, we will be able to make environmentally friendly and biodegradable plastics widely available, so that we can enjoy the convenience of plastic products and live in harmony with nature.We support custom packaging size, material, design, if you are interested in custom transparent packaging box please feel free to contact us.
