What is bioplastic?

Biodegradable bag supplier introduces you: "Bioplastic" means that all or part of it is made of organic natural materials instead of traditional petroleum. Many bioplastics are biodegradable. This is also one of the biggest advantages of bioplastics. There are three terms about bioplastics that describe "biobased plastics", "biodegradable plastics" and "compostable plastics". Although these terms are similar, they should not be confused.

Bio-based plastic

This is a very broad term that refers to the extraction of part or all of plastic from plants. Starch and cellulose are the two most common renewable raw materials used to make bioplastics. These ingredients usually come from corn and sugar cane. Bio-based plastics are different from common petroleum-based plastics. Although many people believe that all "bio-based" plastics are biodegradable, this is not the case.

Whether plastic comes from natural substances or petroleum, and whether plastic can biodegrade (the process by which microorganisms break down materials under the right conditions) are two issues. Technically, all plastics are biodegradable. But for practical purposes, only materials that degrade within a short period of time (usually weeks to months) are considered biodegradable. Not all "bio-based" plastics are biodegradable. In contrast, some petroleum-based plastics degrade faster than "bio-based" plastics under the right conditions.

Compostable plastics

According to the American Society for Materials and Testing, compostable plastics are plastics that can be biodegraded in a compost yard. These plastics cannot be distinguished from other types of plastics in appearance, but they can be broken down into carbon dioxide, water, inorganic compounds and biomass (biomass refers to various organisms formed through photosynthesis, including all animals and plants and microorganisms), And there are no toxic residues. The feature of no toxic residue is one of the characteristics that distinguishes compostable plastic from biodegradable plastic. It should also be noted that some plastics can be composted in home gardens, while others require commercial composting (temperatures rise much, and the composting process occurs faster).

Corn and sugar cane are the two most popular raw materials currently used to produce bioplastics. Of course, there are many other options. For example, waste from the processing of banana peels, mango peels, and potatoes is used to produce bioplastics and used to develop new packaging. European Snickers candy bar packaging comes from bioplastics.

Which products make use of bioplastics?

Did you know that bioplastics have been around for at least 100 years. Corn oil and soybean oil were used to make auto parts for the Ford Model T. In recent years, bioplastics have been used in various consumer products, such as food containers, food bags, biodegradable cutlery and food packaging. Bioplastics can also be used in engineering-grade applications, such as electrical and electronic enclosures.

In short, bioplastics has entered almost every industry: automotive, electronics, food and beverage packaging, agriculture, textiles and healthcare ...
