Compostable Material PLA
| 1.What is PLA and how does PLA made ? |
| Polylactic acid (PLA) is a new biodegradable material, which is made of starch raw materials proposed by renewable plant resources (such as corn). Glucose is obtained from starch raw material through saccharification, and then high-purity lactic acid is produced by fermentation of glucose and certain bacteria, and then polylactic acid with certain molecular weight is synthesized by chemical synthesis method. It has good biodegradability. After use, it can be completely degraded by microorganisms in nature, and finally produce carbon dioxide and water, which does not pollute the environment, which is very beneficial to environmental protection. It is recognized as an environment-friendly material. Care for the earth, you and I are responsible. World carbon dioxide emissions according to news reports, the global temperature will rise to 60 ℃ in 2030. The treatment method of ordinary plastics is still incineration and cremation, resulting in a large number of greenhouse gases discharged into the air, while polylactic acid plastics are buried in the soil for degradation. The generated carbon dioxide will directly enter the soil organic matter or be absorbed by plants, which will not be discharged into the air and will not cause greenhouse effect. |
| 2.What is PLA plastic application? |
| PLA has achieved large-scale industrial production, and the time has come for PLA products to partially replace traditional plastics. With the support of national policies, the world will usher in a new period of vigorous development of PLA plastic products. The following list shows some common examples of PLA usage |
| 3.What is the difference between PLA and other biodegradable plastics? |
| There are some polymer products on the market called biodegradable plastics. These so-called biodegradable plastics have caused controversy and debate among environmentalists. Oxidative biodegradable plastics actually use a controlled catalyst to initiate chain cracking reactions to attack polymer macromolecules. The catalyst is formed from a series of active organic transition metals added to the polymer. When the oxidized biodegradable polymer is exposed to ultraviolet and free oxygen, the chain cracking reaction takes place in a large area, and the final product is carbon dioxide. Such "environmentally friendly" plastics are controversial because they still come from petroleum based products and their degradation is still to produce carbon dioxide, which violates the principle of carbon credit products. PLA, which uses the biological activity of bacteria to convert plant products (such as starch) into the initial product of polymerization. These polymers use renewable raw materials and have carbon credits in the production process. Again, it shows that the use of microbial derived fully biodegradable PLA as a polymer with carbon credit is very important for the future of sustainable development. |
| 4. What are the benefits and advantage of PLA products? |
|
PLA requires 65% less energy to produce than
traditional, petroleum-based plastics. It also emits 68% fewer
greenhouse gases. And that’s not all: The environmental benefits: Comparable to PET plastics – More than 95% of the world’s plastics are created from natural gas or crude oil. Fossil fuel-based plastics are not only hazardous; they’re also a finite resource. PLA products present a functional, renewable, and comparable replacement. Bio-based – A bio-based product’s materials are derived from renewable agriculture or plants. Because all PLA products come from sugar starches, polylactic acid is considered bio-based. Biodegradable – PLA products achieve international standards for biodegradation, naturally degrading rather than piling up in landfills. It does require certain conditions to degrade quickly. In an industrial composting facility, it can break down in 45–90 days. Doesn’t emit toxic fumes – Unlike other plastics, bioplastics don’t emit any toxic fumes when they’re incinerated. Thermoplastic – PLA is a thermoplastic, so it’s moldable and malleable when heated to its melting temperature. It can be solidified and injection-molded into various forms making it a terrific option for food packaging and 3D printing. Anti-bascterial & mite- PLA surface of polylactic acid is weakly acidic, with strong anti mite effect and natural antibacterial property. The antibacterial rate against Candida albicans, Escherichia coli and Staphylococcus aureus is more than 95%; Flame retardant, less smoke, no black smoke and toxic gas; Moisture proof, moisture conductive, fast drying, and good air permeability, especially suitable for the field of medical care. Breathable & Skin-friendly- PLA has excellent drapability, smoothness, moisture absorption and permeability, natural bacteriostasis, weak acidity that reassures the skin, good heat resistance and UV resistance. FDA-approved – Polylactic acid is approved by the FDA as a Generally Recognized as Safe (GRAS) polymer and is safe for food contact. |
| 5. Are PLA Products right for my business? |
|
If your businesses currently uses any of the following items and you’re
passionate about sustainability and reducing your business’s carbon
footprint, then PLA packaging is an excellent option: All range of packaging bags Food containers Cutlery Cups & straws Cutting Boards |
