| Glass jar or bottle | Rigid and premium-feeling; heavier and breakable. A wide-mouth jar is easy to access but exposes more product to air and fingers than a suitable pump or tube. | Glass can be recycled where collection and processing are available. Its weight increases shipping emissions, and lids, pumps, coatings, or mixed-material parts may need separation. | Medium to high | Consider glass weight, protective shipping materials, breakage risk, closures, and the cost of any protective outer packaging. | Creams, serums, and products where a substantial feel or product visibility is important. |
| PET bottle | Lightweight and impact-resistant compared with glass. Compatible closures and dispensing components depend on the product and design. | PET is accepted in many recycling systems, but acceptance varies by location. Color, labels, residue, and attached components can affect sorting and recycling. Recycled-content availability and suitability vary by specification. | Low to medium | Check resin grade, recycled-content requirements, bottle and closure compatibility, filling-line performance, and local recycling guidance. | Lotions, cleansers, and other products that benefit from a lightweight bottle. |
| HDPE bottle | Lightweight, durable, and suitable for many squeeze or pour applications. The dispensing closure should be tested for leakage and dose control. | HDPE is recyclable in many established collection systems, subject to local rules and package design. Labels, color, residue, and non-HDPE parts can influence recyclability. | Low to medium | Assess bottle wall thickness, closure choice, shipping efficiency, filling compatibility, and the availability of the required material grade. | Shampoo, conditioner, body wash, and other products sold in squeeze or pour bottles. |
| Aluminum tube | Lightweight and squeezable; helps limit product exposure after opening. It can crease during use and may require a compatible internal coating. | Aluminum is recyclable where appropriate collection and processing exist. Coatings, caps, and other components can affect recycling, so local guidance and package construction matter. | Medium to high | Include tube and cap costs, coating requirements, filling equipment, transport protection, and compatibility testing with the formula. | Ointments, creams, and concentrated products that benefit from controlled squeezing and reduced air exposure. |
| Plastic airless pump | Can dispense product with limited air return and controlled doses. The mechanism adds components and may leave some product inaccessible; performance varies by design and formula. | Many airless packs combine different plastics, springs, or other components, making recycling more difficult unless the pack is designed for separation or accepted by a suitable recycling stream. | Medium to high | Account for pump price, assembly, filling-line requirements, priming and dose testing, component compatibility, and product remaining after use. | Formulas that need metered dispensing or are sensitive to repeated exposure to air. |
| Flexible mono-material PE tube | Lightweight and squeezable. Dispensing is simple, but the tube may not empty completely and its barrier performance depends on its structure and formulation. | A tube made primarily from one polymer can be easier to design for recycling than a mixed-material laminate. Flexible-film collection is not widely available everywhere; verify local acceptance. | Low to medium | Check barrier needs, seal quality, tube and cap material compatibility, filling equipment, and whether local collection accepts the finished pack. | Lotions, gels, and creams where flexible, lightweight dispensing is suitable. |
| Paperboard carton (secondary packaging) | Provides space for instructions and product information and can protect a primary pack from scuffs. It adds a packaging step and is not a substitute for a product-contact container. | Paperboard is recyclable in many areas when clean and accepted locally. Laminations, foil, coatings, windows, and heavy finishes can complicate recycling. | Low to medium | Include printing, finishing, carton assembly, packing labor, storage volume, and whether the carton provides enough protection to justify the added material. | Products needing extra information, light protection, or additional protection during transport and retail handling. |
