Personalized Bottle Caps 22mm Plastic Screw Caps In Bulk

1. Product Introduction

The ingenious perfume bottle cap is the finishing touch of the overall design. Selected metal or high-grade acrylic materials, finely polished and electroplated, with a heavy hand feel and extraordinary texture. Every opening and closing is accompanied by a crisp and pleasant "click" sound, giving the use process a full sense of ceremony.

3. Bottle Caps Advantages

The unique sense of weight, cool touch, and high-end luster of metal can greatly enhance the grade and brand image of products, conveying signals of "luxury", "classic", and "high-end". The metal lid has strong durability: it has a sturdy structure, strong pressure resistance, is not easily deformed, and can effectively protect the internal nozzle and bottle mouth. And high processing accuracy: Die casting can achieve extremely fine textures and complex three-dimensional shapes (such as reliefs and hollows), with unparalleled detail expression.
The plastic material lid has high flexibility in design: it can easily achieve extremely complex hollow, transparent, ultra-thin and other shapes, with greater design freedom. Lightweight: Extremely lightweight, suitable for large-sized bottle caps, will not make the product overall "top heavy and bottom light". And it has rich colors and effects: it can achieve any color (transparent, solid, pearl) without electroplating, and the coloring is uniform.

4. Bottle Caps Application:

Metal Lid:
Die casting: Injecting molten zinc alloy into precision molds under high pressure to form a structurally complex cover in one go is the mainstream technology.
Electroplating: This is the core technology for achieving a gorgeous appearance of metal covers. Coat the surface of the substrate with a layer of metal such as nickel, chromium, gold, palladium, etc., to provide anti-corrosion protection and brilliant color.
Spraying and coloring: PVD (Physical Vapor Deposition) coating, transparent paint spraying (protective coating), or special coloring treatment (such as aging, enamel) can be performed.
Inner lining assembly: A plastic inner liner (inner plug) must be installed inside the metal cover. The inner liner is usually made of ABS or PP, with an embedded elastic gasket (commonly PE or PTFE) inside, which is the key component that directly contacts the glass bottle mouth and achieves airtight sealing.

Plastic Lid:
Injection molding: Injecting molten plastic into a mold, cooling it, and forming it is a core and efficient production technology.
UV coating (vacuum coating): Coating a very thin metal film on the surface of plastic to give it a metallic luster, but at a lower cost than electroplating with water.
Spraying: Metal paint, rubber paint (providing a soft touch), pearl paint, etc. can be sprayed.
In mold injection molding (IMD): Place the pattern film into the mold, and after injection molding, the pattern is embedded on the surface, which is wear-resistant and cannot be removed.
Integrated internal sealing: Through exquisite mold design, elastic sealing structures (such as soft rubber rings) are integrated with hard covers in one or two injection molding processes.
