Polymer laminated glass bottles for lightweight beverage packaging
Introducing polymer laminated glass bottles that offer a lighter and safer alternative to traditional glass beverage packaging. These bottles maintain essential performance properties like gas barriers and recyclability while providing enhanced safety and reduced weight.
Overview
This innovative solution presents polymer laminated glass bottles designed to revolutionize beverage packaging. By integrating a polymer layer between two layers of glass, these bottles maintain the essential properties of traditional glass packaging such as transparency, gas barrier effectiveness, and recyclability. The primary advantage is their reduced weight and enhanced safety, making them a superior choice for manufacturers looking to optimize their packaging solutions without compromising performance.
Technical specifications
The laminated glass bottles consist of three layers: an inner and outer glass layer with a polymer layer sandwiched in between. This design leverages the strength and transparency of glass while utilizing the lightweight properties of polymers. The polymer most commonly used in such applications is polyvinyl butyral (PVB), selected for its mechanical performance and compatibility with glass. The manufacturing process involves heat and pressure to adhere the layers, ensuring durability and transparency. Key considerations include selecting polymers with suitable mechanical properties, ensuring optical transparency, and addressing potential regulatory and product performance issues.
Technology readiness level
Currently, this technology is at a TRL 2. The concept has been formulated, and the next phase involves partnership with a glass bottle manufacturer to develop a three-layer laminated bottle. This phase will address manufacturing challenges and test various polymers for optimal performance, with the aim of advancing to higher TRLs.
