What is a returnable glass bottle?

The "Odyssey" of a returnable bottle

After its first use, a returnable bottle has to go through a washing process with hot caustic used by fillers. Hot and Cold-end coatings are washed off successively and scuffing is generated every cycle by constant filling, washing, shipping, and stocking on shelves in consumer stores. This is why the overall appearance in the lifetime of a bottle will depend on the caring solutions you choose.


Packaging strategy

The aesthetic of your bottles is the heart of our expertise and our technologies are the solutions to place packaging in the center of your brand strategy. Moreover, it is also a commitment to final consumers who have first contact with your product.

Packaging strategy is critical in the beverage market across the world. Returnable glass bottles offer advantages on environmental impact and cost among others. Kercoat® protective coating will prevent returnable bottles from scuffing, scratching, and wearing even up to 50 cycles of filling.

Kercoat® is designed to fit into the life cycle of returnable glass bottles by:

  • Brings protective coatingafter caustic washing process
  • Extends bottle aesthetics over time thanks to its anti-scuffproperties
  • Reduces friction and damage during bottle to bottle contact
  • Reduces costsof bottle pool over time
  • Keeps burst pressure strength at higher level for considerable safety aspect
  • Bringslubricity on the bottles and increases productivity.


Beverage manufacturers need a solution to keep returnable glass packaging looking new, even after many cycles of filling and shipping to customers. Brand image depends on having a bottle look clean and free of scuffing or cracking. To help the bottle survive the returnable life-cycle, Arkema developed the Opticoat® technology. Opticoat® masking coatings are designed to: 

  • Mask scuffing rings and help bottles appaer "new" by providing a nice and shiny look and feel
  • Offer competitive advantage over uncoated bottles
  • Function well on dry or cold and wet bottle surfaces > Opticoat® 140/150
  • Survive harsh storage and transport conditions.
