Start with the formula, not the look
Cosmetic and personal care products vary widely in how they interact with packaging. A water-based lotion, a silicone-heavy primer and a fragrance oil each place different demands on the pack. Before choosing a pouch, bottle or tube, list what the formula contains: water, oils, alcohol, acids, essential oils, fragrance or preservatives. These ingredients drive the barrier requirement and the material structure. A pack that looks right but fails on compatibility will leak, swell or degrade on the shelf.
Also note how the product will be used. A daily-use serum may need a pump or dropper for controlled dosing. A sample sachet may only need a tear notch and a clean tear path. A refill pouch needs a resealable feature if the consumer will decant it more than once. Mapping the use case first avoids over-specifying the pack and paying for features the product does not need.
Material structures for cosmetics
Flexible packaging for cosmetics commonly uses laminates. PET/AL/PE gives a strong light and oxygen barrier, making it suitable for products with fragile oils or vitamins. PET/NY/PE offers good puncture resistance and flex crack resistance, which matters for squeezable packs and travel sizes. Kraft paper laminates suit brands that want a natural look, often combined with a PE or AL layer for product protection. Mono-material PE and PP recyclable structures are available for brands that need to meet recycling guidelines. PLA/PBS compostable options exist for specific applications.
For rigid or semi-rigid formats, cosmetic brands use airless bottles, tubes and jars. These are outside Clover's core range, which focuses on flexible packaging: flat bottom pouches, stand up pouches, flat and three-side-seal pouches, spout pouches including corner spout and STANDCAP, side gusset bags, rollstock film and special shaped bags. If your product is a cream, gel, serum or powder, a flexible pack with the right fitment can replace a rigid container and reduce material weight.
Barrier and shelf-life decisions
Barrier is a balance between protection and cost. Light barrier protects photosensitive ingredients. Oxygen barrier slows oxidation of oils and actives. Moisture barrier prevents drying out or clumping. Aluminium foil layers give the highest barrier but block any view of the product. Transparent high-barrier coatings and metallised films offer a middle ground. Clear packs without a barrier work for stable formulas with short shelf life, such as samples or products sold quickly.
Shelf-life testing should match the pack to the formula. A common mistake is to approve a structure based on appearance alone, then find that the product loses scent or changes colour after a few months. If you cannot run a full stability test, ask your packaging supplier for guidance on typical barrier levels for similar products. The manufacturing partner can advise on standard structures, but the brand remains responsible for final compatibility and shelf-life validation.
Filling, sealing and decoration
Filling method affects pack design. Vertical form-fill-seal works with rollstock film for sachets and stick packs. Pre-made pouches are filled through the top opening or through a spout, then sealed. Spout pouches need a fitment that matches the filling equipment and the cap style. For powders, consider a wide opening or a scoop-friendly shape. For liquids, a spout with a controlled flow reduces mess. Always confirm the fill temperature and product viscosity with the packaging supplier before finalising the structure.
Decoration choices include rotogravure printing up to 10 colours, digital printing and flexographic printing. Rotogravure suits long runs and photographic detail. Digital printing suits short runs and multiple SKUs. Add-ons such as a one-way degassing valve, zipper, tear notch, window, spout and cap, carry handle or hang hole can be specified. A window can show the product, but it removes barrier in that area. A zipper adds convenience but can increase unit cost and may not suit fine powders.
Cost drivers and common mistakes
Cost per pack depends on structure, size, print method, run length and add-ons. Digital printing has a lower MOQ, from 100 pcs for pouches or 10 kg for film, with lead time of 10-15 working days after artwork approval. Rotogravure requires higher volumes, from 10,000 pcs or 200 kg, with lead time of 20-25 working days. Adding a spout, valve or zipper increases material and conversion cost. Reducing pack size or simplifying the structure can lower unit price, but check that barrier and filling needs are still met.
Common mistakes include choosing a material that is not compatible with the formula, ordering too few units for a test then running out before reorder, and approving artwork without checking print tolerances. Another is forgetting that recyclable and compostable structures have specific processing and disposal requirements. Free stock pouch samples are available so you can check fit, feel and function before committing to a custom run. Courier costs for samples are paid by the customer.
