Fully biodegradable material - PLA material

A fully biodegradable material is a plastic whose properties meet the requirements of use, remain unchanged during storage and degrade to an environmentally friendly substance in the natural environment after use. It is therefore also known as an environmentally fully biodegradable material.

 

The degradation process of degraded materials mainly includes biodegradation, photodegradation and chemical degradation. The degradation processes are mainly synergistic. For example, photodegradation and oxidative degradation often occur simultaneously and contribute to each other; photodegradation is more likely to occur after photodegradation.

PLA is one of the most researched biodegradable materials in China and abroad. It is made by polymerising lactic acid as the main raw material. PLA is a non-polluting, biodegradable product. When the temperature is higher than 55°C or when oxygen enrichment and microbial action are reduced, PLA can be decomposed into carbon dioxide and water by composting, and the material is recycled in nature without any impact on the environment. Currently, polyacrylate ring-opening polymerisation is mainly used in the production of PLA. PLA is prepared by dehydrating lactic acid into oligomers, depolymerising it into propyl esters and then subjecting it to ring-opening polymerisation. PLA also has reliable biosafety, biodegradability, good mechanical properties and is easy to process. The disadvantage of PLA is the relatively harsh degradation conditions. However, PLA is at the forefront of consumption due to its relatively low cost among biodegradable plastics.

food packaging, disposable tableware and medical materials being its three most popular applications.

How are drinking straws made?

Drinking straw is widely used in our daily life, there are many types like paper straw, plastic straw, PLA straw,

 

PLA straw paper straw plastic straw

While most people don’t know how these straws are made,in this article, we are going to explain how these plastic /PLA drinking straws are made.

 

The manufacture of straws involves several steps. First, the plastic resin is mixed with the other ingredients; then the mixture is extruded into a tube shape; the straws may undergo subsequent specialized operations, and finally, the straws are packaged for transport.

 

1. Plastic compounding(Material)

 

straw-making factories can get plastic/PLA resin from material suppliers. mostly use PP/PLA granules for the straw extrusion

 

2. Straw extrusion

 

The PP/PLA pellets are dumped into a hopper at one end of the machine and are forced through a long channel by a screw mechanism. The screw rotates inside the barrel and is powered by an electric motor running through a gear reducer. As the screw rotates, it moves the resin along the barrel. As the resin moves along the heated channel, it melts and becomes easier to flow. To ensure good movement and heat transfer, the screw has only a few thousand inches of clearance inside the barrel. It is machined from strong steel rods and almost all surfaces in contact with the barrel are hardened to prevent wear. By the time the resin reaches the end of the barrel, it is completely melted and can be easily extruded through the opening in the die.

 

The resin exits the die in a long string in the shape of a straw, the diameter of the straw can be adjusted by the mold & airflow, the straw will go through the cooling water tank, then will be pulled by the hauling & cutting machine, Ultimately, the long tubes are cut to the proper length by the cutting machine
