Aerosol Spray Cap is Recyclable

Weener Plastics has developed a fully recyclable aerosol spray cap, called the Ultimate Spray System, which consists of a two-piece spray cap made from a single material. According to Weener, the cap offers spray performance equal to proven, conventional spray caps.

Mono-material: PP Insert

To achieve refined spray patterns for specific application requirements, aerosol products often use a spray cap with an insert. Traditionally, inserts are made of PMMA, which cannot be recycled and disrupts waste streams. To address this, Weener makes both the insert and cap from PP, which can be recycled in standard waste streams. For true circularity, the cap is also available in recycled PP.

Removable Spray Cap

The PP spray cap can be easily and conveniently removed from the aerosol container before disposal. The finger-button can be lifted, at which point the housing of the spray cap is torn open and can be removed. The separate spray cap and aerosol container can then be disposed of in the appropriate waste stream.

Weener Plastics anticipates adoption of the spray system by customers involved in personal and home care products. Customers will be able to customize the spray characteristics including orifice and spray pattern. The caps fit standard aluminum and tinplate aerosol containers and can be processed on standard filling lines.
