Customizable Anti-Leak Moisture-Proof Disc Caps – 3D Design Available

Leakage is the enemy, and we've engineered our caps to fight it on every front. The secret starts with the seal—our caps feature a precision-engineered inner lining that conforms tightly to the bottle's neck, creating a barrier that even the thickest lotions or thinnest serums can't break through. Many of our caps also come with an optional aluminum foil liner, which adds an extra layer of protection against moisture and air. Think of it as a double lock for your product's freshness.

But we don't just stop at the seal. The disc itself is designed with a smooth, flexible hinge that snaps shut with a satisfying "click," ensuring it stays closed during transit or when tossed in a bag. We've tested these caps in real-world scenarios: dropped from waist height onto concrete, shaken in a tumbler for hours, even stored in extreme temperatures (from freezing cold to sweltering heat). The result? Zero leaks, every time. Because when you're trusting a cap to protect your product, "maybe" isn't good enough—you need "definitely."

Moisture is a silent killer for many products. It can cause creams to separate, powders to clump, and even create a breeding ground for bacteria. That's why our caps are built with moisture resistance in mind, starting with the materials we choose. Most of our disc top caps are made from high-quality HDPE (High-Density Polyethylene) or PP (Polypropylene), both of which are naturally resistant to water and moisture. These materials don't absorb liquids, so even if the outside of the cap gets wet (like in the shower), the inside stays dry, protecting your formula.

For extra-sensitive products—like organic skincare or pharmaceutical creams that need to stay sterile—we offer caps with moisture-proof liners that act as a barrier against humidity. We also design the cap's interior to minimize air pockets, where moisture could linger. It's these small, intentional details that add up to a cap that doesn't just "work"—it works hard to keep your product as fresh on the day it's used as the day it left the factory.

Whether you're packaging a tiny 30ml travel-size lotion or a large 500ml shampoo bottle, we have a disc top cap that fits. Our caps come in a range of sizes and neck finishes, designed to work with standard bottle threads so you don't have to redesign your entire packaging line. Here's a quick look at some of our most popular options (and if you don't see what you need, we can custom-make it—more on that later!):

This table just scratches the surface—we also offer 20/410, 28/415, and custom sizes for unique bottle designs. The point is: no matter what bottle you're using, we can find (or create) a cap that fits like a glove.

Ever had an idea for a cap but weren't sure how it would look in real life? Our 3D design service takes the guesswork out of the process. Here's how it works: You share your vision—maybe you want a cap with a curved edge instead of a flat one, or a logo that's raised (embossed) instead of printed. Our design team then creates a detailed 3D model of the cap, which you can view from every angle on your computer or phone. You can tweak the design as much as you want—change the color, adjust the size of the logo, even test different liners—until it's perfect. No more expensive mistakes or "surprises" when the caps arrive—you'll know exactly what you're getting before we make a single mold.

And if you don't have a design yet? No problem. Our team can work with you to brainstorm ideas based on your brand aesthetic, target audience, and product needs. We've helped everything from luxury skincare brands create sleek, gold-accented caps to eco-friendly companies design caps made with recycled materials. The goal is simple: make sure your cap doesn't just seal your bottle—it tells your brand's story.

Sometimes, standard sizes or shapes just won't cut it. Maybe you have a unique bottle design with a non-standard neck, or you want a cap that's completely one-of-a-kind to stand out on store shelves. That's where our custom mold design service comes in. We don't just "modify" existing molds—we build new ones from scratch, tailored to your exact specifications. And yes, we offer free mold testing to make sure the cap fits perfectly before you place a full order. It's our way of ensuring you're 100% happy with the final product.

Our mold-making process is fast, too. Thanks to advanced CNC machining, we can turn a 3D design into a functional mold in as little as 2-3 weeks (depending on complexity). And because we handle the entire process in-house—from design to manufacturing—we can keep costs lower than many competitors who outsource mold-making. So whether you need 10,000 caps or 100,000, custom mold design is within reach.

Your cap is a mini billboard for your brand, so why not make it count? Our private label services let you add your logo, brand colors, or even a custom message to your caps. Choose from silk-screen printing (great for bold, bright logos), hot stamping (perfect for metallic accents like gold or silver), or embossing (for a raised, textured logo that feels premium). We can even match your brand's exact Pantone color, so your caps coordinate seamlessly with your bottles and labels.

For example, if you're a natural skincare brand with a earthy color palette, we can make caps in soft greens or browns with your logo embossed in a subtle, matte finish. If you're a bold, youthful brand, we can do bright pink caps with a glossy finish and your logo printed in neon orange. The options are endless, and the result is a cap that doesn't just hold your product—it reinforces your brand identity every time a customer uses it.

ISO 9001 is an international standard for quality management systems, and it means we follow strict processes to ensure every cap is made the same way, every time. From testing raw materials (we only work with suppliers who meet our quality standards) to inspecting finished caps (each batch is checked for leaks, cracks, and proper fit), we leave no room for error. This consistency is crucial if you're ordering caps in bulk—you don't want the first 1,000 caps to be perfect and the next 1,000 to have loose hinges or faulty liners. With ISO 9001, you can trust that every cap meets the same high bar.

GMP (Good Manufacturing Practices) is especially important if you're making products that need to stay sterile, like pharmaceutical creams or organic skincare. Our dust-free workshop is designed to minimize contaminants: air is filtered through HEPA systems to remove particles, employees wear protective clothing (hairnets, gloves, gowns), and surfaces are sanitized regularly. Even the equipment is cleaned and maintained daily to prevent dust or bacteria from getting into the caps. The result? Caps that are safe to use with even the most sensitive formulas, from baby lotions to prescription medications.

We also understand that transparency matters. If you want to see our facilities for yourself, we're happy to arrange a virtual tour (or an in-person visit, if you're local). We'll show you how we make the caps, test them, and package them—so you can feel confident that you're partnering with a factory that prioritizes quality and safety.

From facial cleansers to body lotions, our caps are a favorite among cosmetic brands. The smooth, easy-to-open design makes them user-friendly (no struggling with tight caps in the shower!), and the moisture-proof seal keeps formulas like serums and oils fresh for longer. We've worked with brands to create caps in custom colors that match their product packaging—like a rose gold cap for a luxury rosehip oil, or a matte black cap for a men's skincare line.

Shampoo, conditioner, hand soap, body wash—these are products people use every day, and they need caps that can keep up with frequent use. Our caps are durable enough to withstand being opened and closed multiple times a day, and the anti-leak design means they're perfect for family bathrooms (no more sticky spills on the counter!). We also offer caps in larger sizes (like 28/410) for big bottles, and smaller sizes (like 18mm) for travel sets.

When it comes to medical and pharmaceutical products, there's no room for error. Our GMP-compliant caps are designed to meet strict safety standards, with moisture-proof liners that protect pills, creams, and ointments from humidity. We also offer tamper-evident caps, which have a small ring that breaks when the cap is first opened—letting users know the product hasn't been opened or tampered with before they buy it.

Even cleaning products need reliable caps! Our HDPE caps are chemical-resistant, so they can handle everything from dish soap to all-purpose cleaners without cracking or degrading. The anti-leak design is also a plus for products that might be stored under sinks or in cabinets—no more leaks that damage wood or attract pests.
