Because they are better for the environment (biodegradable - will rot down and create fertile soil) and because crude oil was not needed to develop the material, they used cornstarch, so it is renewable.

PLA is used in carrier bags, sandwich containers, plastic cups and plastic cutlery.

hope this help :)

What is the melting point of pla plastic?

The melting point of polylactic acid (PLA) plastic typically ranges from about 150°C to 160°C (302°F to 320°F). However, the exact melting point can vary depending on the specific formulation and additives used in the PLA. PLA is known for its relatively low melting point compared to other thermoplastics, making it suitable for 3D printing and biodegradable applications.


What is PLA's monomer?

polyethene is the 1st and then the third =2.45 i 6658 (poly)hydron b2 1 Poly(methane) Poly(pentane( This is all a load of rubbish dont believe it


What is the monomer for bio-plastic?

The monomer for bio-plastic is typically derived from renewable resources such as corn starch or sugarcane. One common example is polylactic acid (PLA), which is made by fermenting sugars to produce lactic acid, which is then polymerized to form PLA bio-plastic.


How does post consumer regrind compare with PLA?

Post consumer regrind is Plastic (mainly HDPE, LDPE and PET) that has been cleaned and reground into pellet or flake form to make a new plastic object (packaging is a big one). So, in short post consumer regrind or PCR is recycled plastic. PLA is short or Poly lactic acid and is one of many bioplastics. This one is specific is made from corn starch. Not sure but I think Natureworks is the main supplier. The difference is PCR is more stable and has many more uses because the material is just recycled plastic. PLA, because it is made from natural substances, breaks down, melts and losses its rigidity a lot faster and is typically used for one time use. PLA is best used for products that will not have to endure long shelf life or hold volatile products. There are many advancements being made to bioplastics/biopolymers that will improve its rigidity, strength and shelf-life. It's almost hard to keep up! PLA is only one of many biopolymers. They can be made from starches such as potato, pea and corn as well as sugar. But I'm sure there's many more in development! I am a rigid packaging distributor and work with a lot of Plastic!


When were antibiotics developed and commercialized?

Antibiotics were developed in the 1920s and later commercialized in the 1940s.
