Polylactic acid, also known as poly(lactic acid), belongs to the polyester family.paper drinking straws wholesale
PLA is a polymer made from the polymerization of lactic acid as the main raw material. The raw material source is abundant and renewable. The production process of PLA is pollution-free, and the product is biodegradable and naturally recyclable, making it an ideal green polymer material. Polylactic acid (PLA) is a new type of biodegradable material.black double wall paper cup with lid coffee cups
Starch raw materials extracted from renewable plant resources (e.g. corn) are fermented to lactic acid and then converted into PLA by polymer synthesis.
Advantages of polylactic acid (PLA)：
1.PLA has good biodegradability. It can be completely degraded by microorganisms in the soil within one year after being discarded, producing carbon dioxide and water, which will not cause environmental pollution. It truly “originates from nature and returns to nature”! According to news reports, the global temperature will rise to 60°C in 2030.sugarcane tray wholesale
Ordinary plastics are still disposed of by incineration and cremation, causing large amounts of greenhouse gases to be released into the air, while PLA is buried in the soil and degraded. single wall paper hot drink cup with handle
Carbon dioxide goes directly into the soil organic matter or is absorbed by plants and is not emitted into the air, causing no greenhouse effect.
2. PLA is suitable for various processing methods, such as blow molding and injection molding. It is easy to process and has a wide range of applications. It can be used to process a variety of food containers, packaged foods, fast food lunch boxes, non-woven fabrics, industrial and residential fabrics from industrial to residential, such as Gramman biodegradable disposable cup lids, 12 oz. hollow double wall paper cups and compostable food grade rectangular paper bowls. They are then processed into agricultural fabrics, healthcare fabrics, wet wipes, hygiene products, outdoor UV resistant fabrics, tent fabrics, floor mats, etc. The market prospect is very promising. It can be seen that its mechanical and physical properties are good.
3.The basic physical properties of polylactic acid (PLA) are similar to those of petrochemical synthetic plastics, which means that it can be used in the manufacture of a wide range of applications. PLA also has good gloss and transparency, comparable to films made from polystyrene, which other biodegradable products do not offer.
4.Good compatibility and degradability. PLA is also widely used in the pharmaceutical field, such as the production of disposable infusion devices, non-disintegrating surgical sutures, etc. Low molecular weight PLA is used as a drug slow release packaging agent.
5.Polylactic acid (PLA) has the best tensile strength and ductility. PLA can also be produced by a variety of common processing methods, such as melt extrusion molding, injection molding, blow molding, foam molding and vacuum molding. It has similar molding conditions to the polymers widely used today, and it also has the same printing properties as conventional films.8×10 paper bags
In this way, PLA can be made into a variety of applications to meet the needs of different industries.
6.When polylactic acid (PLA) is incinerated, it has the same calorific value of combustion as incinerated paper, which is half that of traditional plastics such as polyethylene, and incineration of PLA never releases toxic gases such as nitrides and sulfides… The human body also contains lactic acid in monomeric form, which demonstrates the safety of this decomposable product.
7.Polylactic acid (PLA) film has good air permeability, oxygen permeability and carbon dioxide permeability. It also has odor barrier characteristics. wholesale pla spoon
Viruses and molds can easily adhere to the surface of biodegradable plastics, so there are concerns about safety and hygiene.popcorn cups with lids
However, PLA is the only biodegradable plastic with excellent antibacterial and antifungal properties. With the increasing emphasis on resource conservation and environmental protection, can plastics be replaced and upgraded?single wall paper cup wholesale
The widespread use of biodegradable biomass material, polylactic acid (PLA), will not only alleviate the resource dependence caused by the “oil crisis”, but will also eradicate white pollution once and for all.
