Brands using sensitive products face several challenges: protecting their products from light, ensuring the recyclability of their packaging, and strengthening their brand identity. How to reconcile these issues of protection, eco-design and image? HDPE and opaque PET packaging do not meet the requirements of recycling flows: only clear PET containers allow closed-loop recycling. LDPET, a full-body sleeve label compatible with the recycling of clear PET, has been a recognized and proven in the beverage market for over 15 years. It is now enriched with a light-blocking function to meet the specific needs of light-sensitive liquid food products: - Light blocking with a transmission < 1%. - Preservation of organoleptic properties: taste, color, vitamin content - Increases the shelf life of products Brands can reconcile recyclability, product quality and shelf visibility.
