PLA: The Sustainable Alternative to Other Plastics

Compared to other “green” plastics such as PETE, PEF, and PHA, PLA offers better strength at a lower cost . And it can be used in more applications than its alternatives. In addition,  it is made from renewable resources, rather than petrochemicals, as other forms of plastic production are. So it is a better choice for those looking to reduce their carbon footprint. Unlike conventional plastics from fossil fuels and other non-renewable resources, PLA comes from renewable resources, such as cornstarch, sugar cane, and cassava. Plastic has become a significant part of our everyday lives,  but the environmental effects of traditional plastics have left many searching for an alternative. Fortunately, there is one. Polylactic Acid  is a sustainable solution that provides all of the benefits of traditional plastics without any drawbacks.

What is PLA, and how does it differ from other plastics?

PLA, or polylactic acid, is a polymer from renewable resources such as corn starch or sugar cane. It is biodegradable and compostable, meaning it can be broken down into harmless products when exposed to certain conditions. It commonly use to produce food packaging, textiles, and 3D printing materials. It’s also famous for its versatile uses due to its low melting point and accessible molding properties.

The difference between PLA and other plastic

The PLA’s manufacturing process also makes it different from most other plastics. Unlike petroleum-based materials, which are melted and injected into molds to create the desired product, PLA is produced using heat extrusion technology which causes the raw material pellets to be melted and pushed through a die, making long strands of plastic that are then cut into small pieces for use in various applications. This results in plastic with better durability and a longer lifespan than traditional thermoplastics.

It also differs from other types of thermoplastics in its processing temperature range. The average melt temperature needed for standard PET plastic ranges between 200°C and 250°C . While, on the other hand, PLA needs only around 150°C – 175°C to produce successful results. This lower temperature during production means faster cycle times. It can make parts with less deformation due to overheating — a bonus, if you’re looking for particular items or trying to achieve a specific finish on your product.

Factors to consider when choosing PLA

There are several important factors people have to consider when considering whether or not PLA is suitable for your project. If cost savings is your primary concern, then PLA may not be appropriate since its higher price point will drive up costs significantly over time compared with more traditional plastics such as PET or Acetal/Delrin materials. Additionally, its higher melting point somewhat limits its uses . But if you’re looking for something that won’t leach pollutants into food or water,  then PLA is worth exploring further!
