PLA full biodegradation conditions:

Under the composting environment,PLA ill be decomposed into lactic acid. After the polymer is decomposed,

lactic acid will be engulfed by bacteria and then converted into water and carbon dioxide.

It will take about 90-180 days depending on the size and thickness of the product and the composting environment.

A compostable environment refers to the existence of three main elements:

High temperature ( 58~70 ℃ ), high humidity, bacteria.

(1) Sufficient relative humidity of more than 90%.

(2) Sufficient oxygen (non-closed environment).

(3) Appropriate temperature.

Product Introduction

PLA takes annually renewable resources – corn, cassava and other plants as raw material. After fermentation by microorganisms, lactic acid will be extracted, then PLA will be produced through a process of refining, dehydration polymerization, high temperature pyrolysis and final polymerization. Modified PLA hes has excellent biodegradable property. After disposal, within one year, it can be degraded into carbon dioxide and water by microorganisms in the soil, and do no harm to our environment. PLA is a kind of aliphatic polyester with basic characteristics of general micromolecule materials. PLA modified masterbatch has good machanical properties, low shrinkage, and is competent to the application of most synthetic plastics, also it s widely used in the production of package materials, disposable tableware,household electrical appliance shell, fiber, 3D supplies etc.

Because modified PLA masterbatches derives from plant resoures but not the petroleum-based traditional plastics, so it can truely realize energy-saving and enviromental protection, and PLA is considered to be the most promising new ecological material.

Biodegradable particle color: transparent/translucent/not transparent/other staining, etc.

The market often uses different types of degradablemodified pellets：

1. The material composition is different, the quality isdifferent, the purchase quantity is different, and the price is different.    

2. ($：cost) ($$：cost) ($$$：cost) ($$$$：cost) ($$$$$：cost)

$：Sunshine degradable plastic: Mix traditional plasticmaterials (PS, PP, PE, PVC, etc.) withphotosensitizer to make particles.

$$：Cleavable Plastics: Master-batch made from traditionalplastic materials (PS, PP, PE, PVC, etc.) mixedwith minerals and shellfish.

$$$：Non-PLA composite degradable Plastics: such as compounds,microorganisms, animals, polymerized to make granules.

$$$$：Add PLA modified polymerization 100%biodegradable particles.

$$$$$：Pure PLA modified 100%biodegradable particles.

3. Biodegradable particle color: Translucent / nottransparent / other staining, etc.

4. At present, we can provide polymer modified particles(PLA, PBAT) (, PLA, Plant Starch) (PBAT, Natural minerals) (PBAT, PLA, Natural minerals) (particle coloring) .Can accept customer requirements to add: bamboo fiber, coffee fiber, grain fiber and other biodegradable polymer modified particles. 

5. The current environmental degradation materials, thebuyer wants to reduce costs, the seller wants to increase sales, environmentalprotection degradation materials about 20 to 30 different ingredients, so the quality and priceare very confusing.

6. The more PLA is added, the better the biodegradationeffect and the more expensive the price.

7. At present, there are only three factories in the worldthat produce pure PLA. In the second half of 2019,PLA began to be out of stock, and the price rose sharply. The production PLAcompany adopted a limited allocation of supply to old customers, and PLA wasnot provided to new customers.

8. The PLA plant in the United States allocates 15～18 tons per month to our company.

9. The material composition is different, the quality isdifferent, and the purchase quantity and price are different.

1. Heat-resistant Extrusion grade.

2. General Extrusion grade.

3. Blister grade.
