Aluminum screw-cap for PET spirits bottles
Amcor Rigid Plastics has expanded the use of its roll-on pilfer-proof (ROPP) finish design for aluminum screw-cap PET bottles to the spirits category with new 1.75L and 750ml stock PET bottles that offer light weight and smooth conversion from glass.
The ROPP finish design, available in 30-mm by 60-mm finish (750ml) and 36-mm by 52-mm finish (1.75L), helps enable a smooth conversion from glass to PET with minimal changes on the glass filling line. The ability to use the same aluminum closure for glass on PET bottles is a major advantage, offering brand owners a similar filling experience at reduced changeover and cost. In addition, brand owners are able to mimic the premium look of glass and achieve high-quality aesthetics. The ROPP finish containers are designed to withstand the top load required for aluminum cap applications. The PET bottles meet all required testing to ensure a secure seal with the aluminum closure. The ROPP finish bottle design also eliminates the neck support ring to enhance aesthetics. Various decorating options including custom printing and embossing are available for the aluminum closure. For the 1.75L stock bottle, a standard plastic pour restrictor typically used for glass bottles is incorporated inside the bottle neck to prevent spillage. For spirits makers, the switch to PET also delivers key sustainability benefits. PET containers are lightweight, unbreakable, and easy to transport. Lightweight packaging allows more cases per pallet/truck for fewer shipments, lower transportation costs, and reduced carbon emissions.
