PLA Shrink Sleeves - Biodegradable Solutions
Packaging is an integral part of our daily lives. The use of plastic in the packaging of food products is frowned upon, but various innovations have made it safer. Yet the need for bio-based plastic was always missed. By now, you must be clear about the intention of this article. Yes, you are right! “Plant based Shrink Sleeves” You might have already heard about PLA Shrink Sleeves. Let’s talk about PLA so we can better understand it and use it. Polymer and Packaging Industry is always been a dynamic industry. The product update, renew and replace in short period of time. As a Global Advisor and Director of Taurus Packaging, I have always been the supporter of holistic technologies that create significant steps in closing the loop. With 15 years of active experience and comprehensive exposure, I tend to implement it everywhere I can. PLA, or Polylactic Acid is a plant-based plastic made from fermented starch. It is comparatively new plastic material compared to the other shrink sleeve materials in the industry. PLA is mostly manufactured from corn. It is also made from sugarcane in some regions. Although the usage of PLA shrink labels is only 10% in developing nations, it has a huge scope in the near future. PLA is given due prominence because of its biocompatible polyester property. It is developed in 4 processes: fermentation, separation, lactide conversion, and polymerization. Let’s take a closer look at its properties as a shrink sleeve substrate. It is biodegradable, with a thickness in the range of 45–60 microns. It can be kept at a good temperature of more than 38 °C or less than 4 °C. It can be printed with almost all printing technologies, like – Gravure, Flexo Solvent, Flexo Water based, Flexo UV, Rotary UV offset & Digital printing.
