The Complete Guide to Disc Top Caps and Closures for Cosmetic & Personal Care Packaging

Everything you need to know about selecting the right disc top closures — from material choices and sizing to finding a reliable manufacturing partner.

When it comes to packaging for personal care and cosmetic products, every component matters — from the bottle body to the closure that dispenses the product. Among the most versatile and widely used closure types in the industry are disc top caps and closures. Whether you are formulating a new shampoo, body wash, lotion, or liquid soap, the disc top cap is often the first thing your customer touches. It needs to be functional, leak-proof, and visually aligned with your brand identity.

As a leading plastic packaging supplier in China, MGG Group has been manufacturing precision-engineered plastic closures and containers since 2006. With over 16 years of experience serving the pharmaceutical, cosmetics, and personal care industries, MGG understands that the right closure can make or break a product's user experience.

What Are Disc Top Caps and Why Are They So Popular?

Disc top caps — also known as press-top caps or disc top closures — are a type of plastic dispensing closure that opens and closes with a simple press on one side of the cap. The user presses down on the raised disc, which tilts the closure open, revealing a dispensing orifice. A second press on the opposite side snaps it shut. This one-hand operation makes disc top caps extremely convenient for everyday use in bathrooms, kitchens, and professional settings.

Compared to flip-top caps, disc top closures offer a sleeker profile and a more controlled dispensing experience. They are widely used across:

Key Specifications: Understanding Disc Top Cap Sizing

Disc top caps follow a standardized neck finish system that ensures compatibility with corresponding bottle threads. The most common sizes are designated by two numbers: the cap diameter in millimeters and the thread finish (e.g., 24/410 means a 24mm cap with a 410 thread finish).

MGG Group manufactures a full range of disc top caps in these standard sizes, including 20/410, 24/410, 24/415, 28/410, and 28/415 variants. Each closure is precision-molded to ensure a secure, leak-proof fit with the corresponding bottle neck finish.

Material Choices: PP vs. HDPE Disc Top Caps

The material of your disc top closure directly affects its durability, chemical resistance, and aesthetic appeal. The two most common materials are:

Both materials are BPA-free and food-grade compliant. MGG's manufacturing facilities operate under ISO 9001:2015 and GMP standards, ensuring every closure meets rigorous quality and safety requirements.

Liner Options: Aluminum Foil and Beyond

One critical feature that sets professional-grade disc top caps apart is the inclusion of an induction seal liner. These liners serve multiple purposes:

MGG offers 24/410 disc top caps with aluminum foil liner as a standard option, along with liner-free variants for brands that prefer alternative sealing methods. Custom liner specifications are available for OEM and ODM projects.

Customization: Making Disc Top Caps Your Own
