PEN is a great material for returnable/refillable bottles that need to be cleaned in hot caustic solutions because of its excellent chemical resistance and capacity to endure high temperatures.
A 1.5-L bottle for Bon aqua mineralized water being tested in Uruguay by Montevideo Refrescos S.A., a bottling company controlled by Atlanta-based Coca-Cola Co., is the first significant field test of a bottle manufactured with homopolymer PEN.
The Global Returnable bottles Polyethylene Naphtholate (PEN) Resin market accounted for $XX Billion in 2023 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2024 to 2030.
High-performance polyethylene naphtha late (PEN homopolymer) and naphtha late-based co polyesters, which share some of PEN’s performance attributes, are two of the more interesting developments in the packaging industry in recent years.
The refillable/returnable Bon aqua bottle is manufactured of pricey PEN homopolymer, as opposed to that. High-performance bottles made of co polyesters or PEN homopolymers based on naphthalene’s are starting to emerge from technical forums and make their way onto store shelves all over the world.
Though more work has been done with ISBM containers, applications for extrusion-blown containers and flexible film are also being developed.
The resilience of PEN to UV light is greater. Reusable containers lessen the current garbage and recycling issues brought on by throwaway plastic drinking containers. Additionally, a refillable bottle offers a safer, lighter-weight plastic container in those glass-dominated areas where using non-returnable products is prohibited by law.
The objective is to develop a refillable bottle that is both affordable to make and has the physical properties needed to sustain several refill cycles.
To be commercially viable, a refillable plastic bottle needs to keep its aesthetic and functional qualities over at least 10 and ideally 20 cycles or loops.
A cycle typically consists of an empty hot caustic wash, contaminant inspection (before and/or after wash), product filling and capping, warehouse storage, distribution to wholesale and retail locations, and purchase, use and empty storage by the consumer, followed by an eventual return to the bottler.
