Eyeliner packaging design must consider functionality, aesthetics, and environmental sustainability. The following are the key points:

Pen Barrel Design

Materials and Shapes: They are mostly made of plastic or metal materials such as ABS plastic, which are lightweight and cost-effective. Metal pen barrels are more upscale. The shapes are mostly cylindrical and slender, which are convenient for holding and operating. There are also triangular and other irregular shapes designed to prevent rolling.

Slip-resistant design: The surface is equipped with slip-resistant textures or rubber coatings, such as vertical stripes, raised dots, etc., to prevent slipping during use.

Pen tip protection design

• Sealing cap: made of soft rubber or plastic materials such as PE resin soft rubber sealing caps, which are cost-effective and have good sealing effects, preventing the nib from drying out and leaking ink.

• Nail and Clip: The nail is placed inside the pen barrel, and the clip is attached to the outside of the pen tip, further securing the tip in place and preventing it from moving.

Pen Tip Design

• Precision: The liquid pen tip is extremely fine, ranging from 0.1mm to 0.5mm, allowing for precise drawing; the tip of each pen uses extremely fine fiber or nylon bristles.

• Elasticity and Durability: The tip has a certain degree of flexibility to adapt to different facial contours and pressure, and is made of wear-resistant materials to ensure a long service life.

Capacity design

Consider the frequency of use: Common eyeliner bottles have a capacity of 0.5ml to 1ml, and frequent users can design large-capacity cartridges or replaceable cartridges.

The appearance design

Colors and styles: Bright and vibrant colors or minimalist and sophisticated styles that match the brand's positioning, such as pink for girl brands and gold and silver for high-end brands.

• Pattern and Printing: Use screen printing, hot stamping, and hot silver foil printing to print brand logos, product names, and patterns, which can enhance brand recognition.

Environmentally friendly design

• Recyclable materials: The pen barrel and outer packaging are made of recyclable plastics such as PET and PP plastic to reduce the impact on the environment.

Minimalist packaging: avoid excessive packaging by adopting lightweight, simple designs and reducing material usage.
