PulPac is developing a new generation of fibre-based caps, using its dry-moulded fibre technology.<\/p>\n

<\/p>\n

The caps will be revealed publicly for the first time at the interpack 2026 trade fair, scheduled to take place on 7\u201313 May in D\u00fcsseldorf, Germany.<\/p>\n

Targeting one of the most widely used plastic parts in everyday packaging, the initiative aims to support a shift toward more material-aligned packaging systems.<\/p>\n

The new caps are designed to match the functional and consumer expectations of plastic alternatives while moving to a fibre-based solution.<\/p>\n

Early tests show \u201cpromising\u201d performance in thread engagement, opening and closing, sealing architectures and overall tactile experience, according to the company.<\/p>\n

The design also allows a high degree of flexibility, including differentiation between the inside and outside of the cap.<\/p>\n

The development is being carried out with PA Consulting and in close dialogue with industry stakeholders, including Optima, PulPac\u2019s designated machine partner for this segment.<\/p>\n

It builds on work within the Bottle Collective initiative, where complete fibre-based bottle systems, including closures, are being evaluated with several global brand owners and packaging players.<\/p>\n

Early versions of the caps have already been produced and tested in real-life packaging and bottle applications.<\/p>\n

PulPac chief technology officer Charlotte Walldal said: \u201cAt PulPac, we focus on creating value both in what can be realised today and what comes next in packaging. Advancing fibre-based caps is a natural step in that journey.\u201d<\/p>\n

Last year, SIG partnered with<\/a> PulPac to develop paper-based closures for its aseptic cartons.<\/p>\n
