ExxonMobil collaborates with Shrinath Rotopack on sustainability initiatives for India
Sustainability has grown in importance in India, especially in the last few years. With the publishing of the Plastic Waste Management Rules (PWMR) by the Indian authorities that include phasing out the manufacture of non-recyclable or non-energy recoverable or multi-layer plastics (MLPs), ExxonMobil took up the challenge of replacing MLPs with recyclable full polyethylene (PE) laminated solutions.
MLP refers to whatsoever packaging structure that has at least i layer of plastic every bit the chief ingredient combined with i or more layer of other materials such as paper, paper board, polymeric materials, metalized layers or aluminum foil.
ExxonMobil decided to tackle the issue of MLPs by replacing them with total PE laminated solutions for non-barrier based packaging applications such as for wheat flour, detergent and salt. The conventional laminate construction for such applications is more often than not PET/PE with PET as the tiptop layer/substrate and PE as the sealing layer. When irresolute from a PET/PE laminate to a full PE laminated solution, customers generally face issues in the post-obit areas;
- A significant drop in packing speed
- Unsatisfactory eyes
- Modify in sealing requirements
- Significant changes in mechanism, resulting in high costs
The challenge was to develop a technical solution for full PE laminates which could run at the desired printing and packaging equipment line speeds, while delivering splendid optical properties. ExxonMobil developed multiple full PE laminated formulations that were specifically designed to address the to a higher place bug, teaming up with the Shrinath Group, a leading film converter in India with excellent infrastructure and production capacity in blown film, press and lamination.
Using ExxonMobil's functioning PE polymers ― including Exceed XP 8784, Exceed 2012, Enable 4009, and Exceed 1327 ― every bit well as ExxonMobil HDPE HTA 108, solutions for the PE substrate/meridian picture show and the PE sealant moving-picture show were successfully produced at Shrinath on their Reifenhauser 3 layer blown film line. They were then converted into laminates after press on Bobst Rotomec rotogravure printing every bit well as Bobst F&K CI flexo press. The lamination was done on Nordmeccanica Simplex machines.
For the course-fill-seal (FFS) packaging trial, ExxonMobil collaborated with Syntegon Technology (formerly known every bit Bosch Packaging Engineering science), a leading supplier of packaging machines. The trials took identify at their Goa found, with ExxonMobil and Shrinath'due south participation. Trials were conducted on an SVZ 1803AR high-speed intermittent-motion vertical-form-fill-seal (VFFS) machine with jaw draw-off technology and servo cross sealing system. Information technology is a compact, versatile and operator-friendly bag maker, and consistently produces accurate bags and quality seals with robust design suitable for abrasive and corrosive products.
Line speeds of a maximum 65 numberless/min for 500g and 1kg packs could be easily achieved without whatsoever operational challenges. Subsequently, the packs passed driblet and leak tests to check the integrity.
