DFRL, Mysuru develops biodegradable water bottles
Mysuru: The Mysuru-based Defence Food Research Laboratory (DFRL), a DRDO lab, has developed a biodegradable water bottle, in an effort to reduce the overall carbon footprint in the environment.
These bottles, developed in a limited quantity, were launched by Union Minister of State for Defence and Tourism Ajay Bhat, here on Friday during the two-day national seminar at SDM College.
According to the release issued by DFRL-DRDO, these bio-degradable are compostable as per the ISO 17088-2021 and IS 17899 T: 2022 standards. These bottles are absolutely safe for food and beverage contact applications and what more, even the bottle cap and label are also compostable.
These bottles look like those other bottles as they too are transparent. Besides, these are durable and strong as any other plastic bottle.
With an aim to check plastic pollution that has become a menace due to indiscriminate littering and also insufficient recycling, these bottles have been developed in collaboration with M/s Konkan Specialty Polyproducts Ltd, Mangaluru. The technology that has been used to develop these bottles is the poly lactic acid manufactured using injection blow moulding technique.
These bottles are yet to be developed for commercial use as the availability of raw materials is scarce, it is said.
Sidel unveils StarLITE®R – a new, ultra-efficient 100% rPET bottle for carbonated soft drinks
To help carbonated soft drink (CSD) packaging producers embrace material circularity, Sidel has launched StarLITE®R – a 100% rPET bottle. Sidel’s signature StarLITE® family is evolving to address the challenges associated with working with recycled content.StarLITE®R allows CSD producers to switch to rPET bottle production with ease and efficiency, while significantly reducing the impact on product quality or packaging integrity.
Embracing 100% rPET
With over 45 years of experience in the blowing and PET packaging sector, Sidel has developed a deep understanding of recycled PET resin characteristics and its impact on bottle production. Laurent Naveau, Packaging Innovator Leader at Sidel, comments on the challenge rPET resin can present the packaging industry:
“The characteristics of rPET are impacted by several factors. Firstly, by seasonality. Consumption habits fluctuate over the course of the year impacting the product category mix. And secondly, by different PET collection models which means that post-consumer PET material bales will vary from region-to-region and even country-to-country. The recycling process and equipment used will also influence PET resin. All these factors can pose new challenges for manufacturers looking to produce bottles with rPET content.”
In addition to common CSD bottle manufacturing challenges such as stress cracking, roll out and bursting during blowing, a higher temperature is also required to process rPET. Consequently, packaging manufacturers can experience reduced control over rPET material stretching and distribution of the substance in the bottle-making process.
Traditionally, greater variability in rPET resin leads to a narrower process window and lower bottle quality.
However, Sidel’s innovative base, StarLITE®R uses leading technologies to ensure efficient rPET bottle production by restoring a much wider process window. The StarLITE®R design is easier to blow as it can be done within a wider range of parameter settings on the blower achieving a much higher quality bottle.
High performance rPET bottle base
To achieve a high performing rPET bottle base, StarLITE®R features an optimised mould base profile and uses an advanced stretch rod end design.
The new mould base profile allows for perfect material distribution through advanced stretching and a high base clearance for optimum stability. The advanced stretch rod end design has improved the preform end-cap material stretching and ensures accurate injection gate centering on the bottle. Finally, the perfect combination of grooves and venting holes allows for high-precision base feet formation.
The new bottle solution also utilises dual external and internal bottle base cooling to ensure a perfect shape. Externally, the process uses a mould base cooling circuit that focuses on the warmer bottle base zones and internally a hollow-stretch rod requiring no additional air supply is used.
