Most bioplastic products are typically made from a blend of PLA, PBAT and starch. Each of these materials have their own unique physical properties like stiffness, flexibility and resilience, but none of the materials have all of the desired properties when used by themselves to make a finished product. That is the reason why they are blended in order to make a Biopolymer copolymer compound that meets the desired performance specifications of the finished product.
What is PBAT (Polybutylene Adipate Terephthalate)?
Polybutylene Adipate Terephthalate (PBAT) is a green eco-friendly biodegradable random copolymer biobased polymer that is both flexible and tough. This makes it an ideal blending resin for other biodegradable polymers that are strong but brittle. PBAT is a good alternative material to use in place of conventional low-density polyethylene that is made from oil or natural gas. PBAT is a biobased polymer that is made from fossil resources. The largest application for PBAT is flexible film that is used to make products like food packaging, industrial packaging, pet waste bags, shopping bags, cling wrap, lawn leaf and garbage bags. In addition, most biodegradable food services items (boxes, dishes, cups) are made from PBAT or one of its copolymer blends. The material is well suited for sheet extrusion, vacuum forming, blow molding and extrusion film applications. When properly stored the material has approximately a 12-month shelf life in the original sealed bag. Once the bag has been opened it is best to reseal the bag properly and use the material within 3 months. When used to make extruded film we suggest the customer uses the material within 6 months to achieve maximum product performance.

What is Polylactic Acid (PLA)?
Polylactic Acid (PLA) is made from renewable green eco-friendly bioplastic polymer, which is typically produced through the extraction and fermentation of starch from plants such as corn, sugar beets, cassava and sugarcane. PLA accounts for the second largest volume of any bioplastic currently being used to make biodegradable and compostable products. It is the most used polymer for making 3D printer ribbon filament, because of its smooth glossy finish, and is easily printable. Polylactic acid can be melt processed like many other plastics to make blown or extruded film, extruded straws, or drawn and spun into fiber. PLA is rigid and 100% compostable, so it is an excellent substitute for making polystyrene or polypropylene forks, spoons, knives, and straws. It is bio-compatible with other bioplastic polymers, so it can be easily processed with PBAT to add strength to film. It can be used in a broad range of manufacturing techniques that include injection molding, extrusion, spinning, casting, and is easily processed on conventional LDPE blown film lines.

Environmental Advantages for using Biopolymers and Bioplastics
- It shows the customer that you are environmentally conscious and care about the Earth.
- Offers the buyer an alternative to using conventional oil or natural gas derived polymers.
- Made from renewable resources such as waste agricultural biomass, corn and potato starch.
- Uses less energy to produce, and lowers the carbon foot print during the manufacturing process.
- The products are biodegradable and compostable when properly managed.
- Protects the environment, conserves non-renewable resources, and reduces landfilled waste.
- Does not alter or impact the scent or taste of the packaged food item.
