PACKAGING SUN CARE
PA+++ comes in CUBE PAK, developed by Tokyo-based Toppan, which is also used to house body washes from Taiyo Yushi Corp. CUBE PAK is described as a highly
water-resistant paper pack, which overcomes the challenge of producing paper containers for use in settings where water is present. Toppan uses a unique structure that ensures no paper edges are exposed at the base of the container, which is potentially constantly in contact with water when used in wet locations, and its water resistance is claimed as being close to that of plastic bottles. Toppan’s transparent barrier GL FILM is laminated onto the inside of the paper pack to maintain formulation quality. A final benefit is that the container’s shape enables the spout to be placed in the centre of the pack, something that has not been possible with conventional paper pack structures. This not only allows for the use of pumps – but it means these pumps can also be removed from empty CUBE PAKs and attached to new ones. Earlier this year, L’Oréal likewise launched La Roche-Posay Anthelios sun protection in one of Albéa’s eco- conscious tubes: a partially cardboard-

based option that reduces the use of plastic by 45% compared with traditional solutions, replacing it with FSC-certified cardboard.
GREEN INSIDE & OUT DSM’s Delaune explained that, due to L’Oréal blazing a trail, “we expect many sun care brands to work now on the sustainability of their packaging”. She adds: “That’s why it was important to DSM to propose one-stop- shop solutions including formulations based on eco-friendly UV-filters combined with eco-conscious packs. For us, this is one of the next big challenges to make sun protection more sustainable.”
“The tube we produced for Royal DSM combines the 3Rs: ‘recycled content’, ‘recyclable-ready’ and ‘reduced weight’,” confirms Hughes. Albéa’s tube used for DSM’s formulation prototypes is composed of the aforementioned Slim Cap, combined with a downgauged web leveraging the company’s Thin-Wall technology for reduced weight solutions. The recyclable packs also incorporate up to 38% PCR material (or 62%, excluding the cap) for a D35, 50ml tube.
SPRAY & PUMP WITH EASE Of course, sunscreen packaging is about more than just the tube or bottle – and Silgan Dispensing’s Mark VII Max Style pump has been developed to minimise some consumer pain points associated with applying sun care in real-life conditions.
It features a larger-than- average finger landing, as well as two ‘ribs’ on the actuator to reinforce grip. These grip lines allow for easy actuation even when fingers have lotion or oil on them – a common hazard for holiday-goers. Mark VII Max Style is suitable for priming high viscosity products, including thicker lotions and gels, and comes in a wide range of spray options, according to Silgan Dispensing.

Home’s range of sun care innovations including airless, aerosols and closures, Dragan and Roullet highlight its PZ and GSA spray and lotion pump solutions.
The PZ Twist option for spray is a “twist-to-lock actuator, without an additional cap, that’s compatible with a pre-compression pump and is also suitable for oil-based and complex formulas”, they explain.
The design – which dispenses with the additional plastic of an easily-lost cap, thereby reducing pack weight – can come either with or without a shielded insert, has a 24/410 neck and comes in two available dosages: 190µl and 290µl. PZ Twist’s design, according to the Aptar Beauty + Home team, includes both ergonomic and environmental benefits, with the former encompassing audible click upon opening and closing, and a ribbed actuator whose optimised design prevents slip. Meanwhile, it boasts 96% recyclability, has a POM- free PP insert, and offers the possibility for actuators, fixtures and collars in PCR material.
Meanwhile, the GSA lotion pump line (which is also available in airless) offers high protection, a high restitution rate and strong performance with high viscosity bulk.
Both Dragan and Roullet observe that the rising popularity of formulas containing mineral filters increases pumps and aerosols clogging, especially for SPF50, where the mix of UV filters can make up to 40% of the formulation.
The high solvent content to achieve a non-greasy, dry-touch feel for such formulations, with common solvents including ethanol, volatile silicones and hydrocarbons, increases the risk of chemical interactions and evaporation, resulting in a “need for protective and robust solutions, like aerosols and spray pumps”, they explain. Similarly, “film formers to build up water resistance and long wear performance… risk clogging and result in the need for high-performing spray solutions like [Aptar’s] PZ2 Technical”. A final trend that Dragan and Roullet highlight is the blurring of the skin and sun care categories. This manifests in sun care ingredients for sensitive skins; products claiming effects like hydrating, anti-pollution, anti-blue light and anti-ageing; preservative-free products; and those containing fragile actives, or premium natural ingredients. Such formulas “require more protection, precise dosage and ease-of-application”, they add, pointing to airless as an ideal option for hybrid solutions
