History of Tube Aluminum-Plastic Caps

Plastic Screw Caps / Flip Caps

First generation — the most common, conventional caps.

High production capacity, cost-effective, and versatile.

Acrylic Caps

Second-generation premium caps that improve tactile feel and visual appearance.

Usually constructed in two or three layers, with an inner cap made of PP and an outer cap made of acrylic or other high-transparency materials such as AS, MS, or PS.

Silicone and Zinc Alloy / Ceramic-Head Caps

Third-generation premium caps that enhance tactile sensation and user experience.

Typically single-piece, two-piece, or four-piece constructions; the massage/dispensing head is made of silicone, zinc alloy, or ceramic.

Special-Style Caps

Third-generation premium caps that enhance tactile feel, aesthetics, and user experience.

Usually two- or three-layer constructions with distinctive shapes and high-end materials, such as PETG or vacuum pump types.

Roller-Ball / Vacuum Check Caps

Fourth-generation functional caps that improve perceived quality and user experience, with better vacuum isolation.

Generally multi-piece constructions, sometimes with vibration features; massage heads may be silicone, zinc alloy, ceramic, or steel ball types.

Tube / Caps Compatible with Beauty Devices

Fifth-generation premium caps that integrate beauty devices with packaging for a stronger sense of technology.

Examples include vibrating eye cream applicators, cleansing device caps, vibrating CC sticks, vibrating massage devices, and features like rechargeable red/blue light, heating, EMS, and pulse functions.
