bulk empty makeup eyeshadow palette distributor

The material selection for eyeshadow cases should balance aesthetics, protection, and environmental considerations:

1. Plastic

Acrylic (Polymethyl Methacrylate)

Light transmittance >92%, similar to glass, but lighter and more shatter-resistant.

Highly corrosion-resistant, withstands long-term contact with cosmetics without deteriorating or deforming.

Recycled Plastic (rPET/PETG)

Contains 30% recycled content, aligning with environmental trends.

Excellent ductility, suitable for custom shapes.

2. Metal

Zinc Alloy

High rigidity supports 360° rotating lens cover.

Magnetic interchangeable design enhances Strong functionality (aluminum palette tolerance ±0.1mm)

III. Other Material Options

Paper inner tray

Honeycomb structure recycled paper mold with waterproof film, 20% increased shock absorption

Requires use with a plastic/metal outer shell

Plant-based materials

PLA corn plastic (highly biodegradable)

Recommended durable eyeshadow palette materials:

I. EVA (ethylene-vinyl acetate copolymer)

Ultra-durable: EVA is extremely flexible and resilient, retaining its shape after repeated use or drops, and resists deformation or breakage.

Cushioning: Its cushioning properties effectively disperse external forces (such as impacts and crushing), protecting the palette from damage and extending its lifespan.

Waterproof and moisture-resistant: In humid environments, it seals out moisture, keeping the interior dry and preventing moisture from deteriorating the eyeshadow.

II. Comparison of other materials

Acrylic: High light transmittance (>92%) and drop resistance, but less cushioning than EVA and may cause scratches with long-term use. Paper inner trays: Typically coated with a waterproof film for shock absorption (up to 20%), but require a metal or plastic outer shell. Standalone packaging offers poor load-bearing capabilities and is susceptible to wear.

Metal materials (such as zinc alloy): High hardness makes them suitable for magnetic replacement designs, but they are also heavier and more expensive, making them less suitable for everyday portability.

Overall Recommendation: EVA offers the best durability, protection, and lightness, making it particularly suitable for frequent portability or for situations prone to impact.

Avoid packaging printed with heavy metal inks and prioritize RoHS-certified materials.
