Beauty brands comparing sustainable cosmetic packaging manufacturers need more than a list of materials described as green. A useful supplier should help the buyer turn a broad environmental goal into a specific change: which component will use PCR, where paper can replace part of a conventional structure, whether a refill system is practical, or whether a durable aluminum shell adds real value to the product.

KAIYA develops these routes for color cosmetic packaging at the product level. The right direction depends on the formula, container structure, visual target, order quantity, and the environmental objective the brand wants to communicate.

1. Begin with One Clear Sustainability Objective

A brief such as “make the package more sustainable” is too broad for component selection. The brand first needs to decide what it wants to improve. Different goals lead to different packaging routes:

• Reduce virgin plastic: use a suitable percentage of PCR in selected plastic parts.
• Create a more paper-forward package: consider paper tubes, paper palettes, sleeves, or outer shells in categories where the structure suits the formula.
• Keep the outer case in use longer: develop a replaceable inner unit with a practical refill supply plan.
• Reduce unnecessary material: simplify decorative layers or components that do not improve protection, closure, or application.
• Improve transport efficiency: review package weight, dimensions, component count, and carton packing.

One clear priority gives the supplier a practical basis for recommending materials and structures.

2. Set the PCR Percentage According to the Product

PCR uses plastic recovered after consumer use and can reduce the amount of virgin plastic required for a selected packaging component. Its environmental value should be connected to the actual PCR percentage and the specific part in which it is used.

PCR content does not have to follow one fixed percentage across every project. For selected plastic components, KAIYA can adjust the PCR direction according to the specific product and the customer's requirements. A brand may request, for example, approximately 30% PCR, 50% PCR, or another project-specific percentage, subject to the selected material, component, appearance target, and production feasibility.

The percentage should be confirmed for a named part such as a cap, bottle body, compact case, or decorative shell. A higher PCR percentage may suit an opaque component, while a clear component may require a lower percentage to protect transparency and color consistency. Buyers should compare the resulting base color, surface, decoration, fit, and function.

For a useful PCR proposal, the buyer should provide:

• the product and component intended to use PCR;
• the preferred percentage, such as 30% or 50%;
• the required color, clarity, finish, and formula-contact status; and
• the expected order quantity and intended claim.

KAIYA can then review the request within its plastic cosmetic packaging range and prepare the relevant material and appearance direction for sampling.

3. Use Paper Where the Product Structure Supports It

Paper can support a more sustainable packaging direction by replacing selected molded-plastic outer parts with a fiber-based structure. The benefit is clearest when paper forms the main tube or palette shell rather than appearing only as a secondary box.

Paper is especially useful when the package already has a relatively simple solid-product or pressed-powder structure. KAIYA's current paper routes are mainly paper lip balm tubes, selected paper lipstick tubes, cardboard eyeshadow palettes, and larger paper tubes for compatible stick formulas.

These formats offer a visible paper material direction and a broad surface for custom artwork. Paper tubes can use natural kraft effects, clean brand colors, detailed floral or illustrated patterns, labels, hot stamping, and other printed designs. Cardboard palettes can also support different pan layouts and large collection graphics without relying on a fully molded decorative shell.

Any coating, liner, adhesive, magnet, film, or plastic inner part should remain part of the material description. The construction of selected paper cosmetic packaging should be recorded so the brand's wording reflects the package that is actually produced.

4. Treat Refillable Packaging as a Complete Product System

A refillable package needs a durable outer case, a secure replacement unit, a simple installation method, and an actual refill SKU. The replacement should sit at the correct height, remain stable during application, and be easy to reorder.

KAIYA's clearest refill-oriented direction includes selected magnetic replaceable aluminum stick packaging. A compatible inner stick can be removed and replaced while the aluminum outer case remains in use. Depending on the selected component and formula, this direction may be considered for foundation, blush, contour, highlighter, balm, or other stick products.

• Outer case: should remain structurally and visually suitable for repeated use.
• Replacement unit: should fit the same case without wobbling, incorrect height, or cap interference.
• Retention: magnetic or mechanical holding strength should keep the refill secure during application and transport.
• Supply plan: the refill needs its own SKU, decoration, instructions, packing, and reorder availability.

5. Understand How Aluminum Supports a More Sustainable Direction

Aluminum is a recyclable material in many markets and is durable enough to support repeated use. In cosmetic packaging, its environmental value is clearest when the aluminum shell is kept as a refillable outer case or when the aluminum component can be clearly identified within the complete package. Actual recycling still depends on the construction and local collection system.

An aluminum shell can remain relatively lightweight while adding rigidity and a more substantial material feel. Anodized colors and selected coated finishes can coordinate the metal surface with the brand design, while the durable shell is useful for cases intended to withstand repeated opening, carrying, and refill replacement.

Within KAIYA's range, this direction is used for selected lipstick, mascara, and stick packages. These structures may still contain plastic cups, mechanisms, bottles, wipers, magnets, adhesives, or coatings, so buyers should confirm which part is aluminum and whether the case is intended for continued use. Related options are shown on the aluminum cosmetic packaging page.

6. Expect Clear Material and Construction Information

A supplier should provide a clear record for the selected route:

• PCR project: component name, resin, target recycled-content percentage, color standard, and approved sample.
• Paper project: paper structure, coating or liner, adhesive, inner support, and applicable decoration.
• Refillable project: reusable outer case, replacement unit, retention structure, installation method, and refill SKU.
• Aluminum project: aluminum outer part, functional inner parts, surface treatment, and whether the package is refillable or single use.

This record supports accurate claims and gives purchasing teams a reference for repeat orders.

7. How KAIYA Supports Sustainable Packaging Projects

KAIYA supports selected PCR plastic components with project-specific percentage options, paper cosmetic packaging, aluminum-led structures, and selected refill-oriented components.

Brands can provide the product, formula, environmental objective, preferred material, PCR percentage where relevant, appearance, quantity, and filling method. KAIYA can compare suitable options, coordinate samples and decoration, and retain the approved direction for wholesale production.
