Your Trusted Partner for High-Quality, Customizable Closures
When it comes to packaging, we often focus on the bottle—the shape, the color, the label. But anyone who's struggled with a leaky lotion bottle or a shampoo cap that won't stay closed knows the truth: the closure makes or breaks the user experience. That's where disc top caps shine, and today, we're diving into two specialized stars of the closure world: 24/415 and 28/415 disc top caps. These "taller thread" closures aren't just another product in the catalog; they're the solution to specific packaging challenges that brands face every day.
As a leading custom plastic bottle manufacturer with over a decade of experience in the industry, we've seen firsthand how the right closure can transform a product. Whether you're packaging luxury skincare serums, everyday hand lotions, or pet grooming products, 24/415 and 28/415 disc top caps offer something unique: a taller thread design that ensures a tighter seal, better compatibility with deep-neck bottles, and a smoother user experience. And with our ISO9001 certified packaging factory and dust-free GMP compliant workshop, you can trust that every cap meets the highest standards of quality and safety.
Let's start with the basics: what do those numbers mean? In the world of packaging, disc top cap sizes follow a simple code: the first number is the diameter in millimeters, and the second (after the slash) refers to the thread finish. For example, "24/415" means a 24mm diameter cap with a 415 thread finish. But what makes 415 special? It's all about height.
Standard disc top caps like 24/410 have a shorter thread, which works well for most shallow-neck bottles. But when you're dealing with deeper bottle necks—think large-format shampoo bottles, 500ml body washes, or thick-walled containers—those shorter threads might not cut it. They might not screw on all the way, leaving gaps that cause leaks, or they might feel wobbly in the user's hand. That's where 415 comes in: the "taller thread" design adds extra length to the threading, allowing the cap to grip deeper into the bottle neck for a secure, rattle-free fit.
Key Difference: 24/415 and 28/415 caps have a thread height of approximately 11.5mm, compared to the 8.5mm of standard 24/410 caps. That extra 3mm might seem small, but it's a game-changer for compatibility with deep-neck bottles.
So, why two sizes? 24mm and 28mm diameters cover the sweet spot for medium to large containers. 24/415 is perfect for 250ml to 400ml bottles—think body wash, hand soap, or pet shampoo—while 28/415 steps up to 500ml and beyond, ideal for family-sized products or industrial-use liquids. Both are designed to handle thicker formulas, too, from creamy lotions to gel-based cleansers, without getting stuck or leaking.
Confused about which size to choose? Let's break it down with a quick comparison. The table below highlights the key differences between standard and taller-thread disc top caps:
| Cap Size | Diameter | Thread Height | Best For | Typical Applications |
|---|---|---|---|---|
| 24/410 (Standard) | 24mm | 8.5mm | Shallow-neck bottles, small to medium sizes (100-200ml) | Travel-sized toiletries, facial cleansers, hand sanitizers |
| 24/415 (Taller Thread) | 24mm | 11.5mm | Deep-neck bottles, medium to large sizes (200-400ml) | Body washes, pet shampoos, liquid soaps |
| 28/415 (Taller Thread) | 28mm | 11.5mm | Extra-deep necks, large formats (400-500ml+) | Family-sized shampoos, industrial cleaners, salon products |
Here's a real-world example: imagine you're launching a 500ml organic body wash in a thick-walled HDPE bottle with a deep neck. A standard 28/410 cap might only screw on halfway, leaving a gap that causes the product to leak during shipping. Worse, customers might struggle to open it, leading to frustration and negative reviews. Swap it for a 28/415 cap, and suddenly everything works: the taller thread grips the bottle securely, the cap opens smoothly with a satisfying "click," and there's zero leakage. That's the difference the right closure makes.
At the end of the day, packaging is about more than function—it's about branding. That's why we offer a full range of customization options for 24/415 and 28/415 disc top caps, so your closures can tell your brand's story as effectively as your bottles do. Let's explore how we can tailor these caps to your needs:
Whether you need caps in your brand's signature Pantone color or a trendy matte finish, we've got you covered. Our in-house color lab can match any shade, from vibrant neons to subtle pastels, using high-quality pigments that resist fading and chipping. We even offer two-tone designs—think a white cap with a black flip-top—or metallic finishes (gold, silver, rose gold) for a luxury touch. No minimum order for standard colors, and low MOQs for custom shades, so even small brands can afford to stand out.
Your cap is prime real estate for branding, and we offer multiple ways to make it yours:
Leakage is the enemy of any liquid product, which is why we offer a range of liner options to ensure a tight, secure seal:
Have a unique vision for your cap? Our custom mold design for plastic bottles (and closures!) service can turn your idea into reality. Whether you need a special shape, a larger flip-top, or a unique grip texture, our 3D design team will create a prototype, test it for functionality, and produce a custom mold—all at a fraction of the cost of other manufacturers. We even offer free mold testing, so you can see and feel the cap before committing to production.
When you're choosing a supplier for your packaging, quality isn't just a nice-to-have—it's a necessity. That's why we've invested heavily in ensuring our production processes meet the strictest global standards. Let's take a closer look at what that means for you:
Our ISO9001 certification isn't just a piece of paper—it's a commitment to consistent quality, from the first prototype to the final shipment. Our quality management system covers every step of the process: raw material sourcing (we only use FDA-approved, food-grade plastics), production monitoring (real-time checks on thread height, closure tightness, and color consistency), and post-production testing (drop tests, leak tests, and durability tests). The result? Caps that perform the same way, every single time—no surprises, no defects, no disappointed customers.
For pharmaceutical packaging or high-end cosmetic products, even a speck of dust can ruin a batch. That's why our disc top caps are produced in a Class 100,000 dust-free workshop—part of our GMP (Good Manufacturing Practice) compliance. What does that mean? Air is filtered to remove 99.97% of particles, workers wear full cleanroom gear (hairnets, gloves, gowns), and equipment is sanitized daily. Whether you're packaging medical-grade hand sanitizer or a luxury face serum, you can trust that your caps are produced in an environment that meets the same standards as pharmaceutical factories.
And it's not just about compliance—it's about peace of mind. When you partner with us, you're not just getting a supplier; you're getting a team that understands the importance of quality in your brand's reputation. We'll even provide batch test reports on request, so you can see exactly how your caps performed during our quality checks.
We know that in the fast-paced world of beauty and personal care, time is money. A delayed packaging shipment can mean missed launch dates, empty shelves, or rushed marketing campaigns. That's why we've built our production and logistics around one promise: fast delivery without sacrificing quality. Here's how we do it:
Unlike some suppliers who outsource production, we control every step in-house—from mold design to manufacturing to packaging. Our factory in Guangdong (a major manufacturing hub in China) is equipped with 20+ state-of-the-art injection molding machines, running 24/7, so we can handle large orders quickly. For standard 24/415 and 28/415 caps in stock colors, we can ship in as little as 5-7 days. For custom colors or branded caps, lead times start at 10-15 days—significantly faster than the industry average of 20-30 days.
Located just 2 hours from the Port of Shenzhen (one of the world's busiest ports), we can get your shipment on a container ship within 24 hours of production completion. We work with trusted freight forwarders who specialize in B2B plastic container wholesale, offering flexible shipping options: sea freight for large orders (30-40 days to major ports), air freight for urgent shipments (5-7 days), or even express delivery (3-5 days) for small batches. We'll even help you navigate customs paperwork, so your caps clear quickly and reach your warehouse on time.
We believe fast delivery shouldn't be reserved for big brands. That's why we offer low minimum order quantities: just 5,000 pieces for standard colors, and 10,000 for custom colors or branded caps. Whether you're a startup launching your first product or a large brand testing a new line, you can get the caps you need without overstocking or tying up cash in inventory.
Today's consumers care about more than just how a product works—they care about how it's made. Sustainable plastic packaging solutions aren't just a trend; they're a business imperative. That's why we've invested in eco-friendly options for our 24/415 and 28/415 disc top caps, helping you reduce your environmental footprint without compromising on quality or cost.
Our PCR (Post-Consumer Recycled) plastic caps are made from 30-100% recycled plastic, depending on your needs. These caps look and perform just like virgin plastic—same strength, same seal, same color options—but with a fraction of the environmental impact. PCR is perfect for brands targeting eco-conscious consumers, and we can even provide certification to prove the recycled content, so you can market your sustainability efforts with confidence.
We've reengineered our disc top caps to be lighter without losing durability. By optimizing the thickness of the plastic and using advanced molding techniques, we've reduced material usage by up to 15% per cap. That means less plastic waste, lower shipping costs (since lighter packages cost less to transport), and a smaller carbon footprint—all while maintaining the same tight seal and user-friendly design.
All our disc top caps are made from HDPE or PP plastic, which are widely recyclable in most countries. We avoid mixed materials (like plastic with metal springs) that make recycling harder, and we can even add recycling symbols or "how to recycle" instructions to your caps, helping educate consumers and boost your brand's eco-credentials.
With so many suppliers in the market, why should you partner with us for your 24/415 and 28/415 disc top caps? Here's what sets us apart:
We don't just sell caps—we solve packaging problems.

We've helped brands of all sizes—from indie startups to Fortune 500 companies—overcome their packaging challenges, and we're ready to help you too.
Our ISO9001 certification and GMP-compliant workshop aren't just for show—they're a reflection of our commitment to quality. Every cap undergoes rigorous testing: we check for leaks, test the flip-top durability (how many times it can open and close before wearing out), and verify color consistency across batches. We even simulate shipping conditions to ensure caps arrive in perfect condition. The result? A closure that your customers can rely on, every single time.
We know that communication is key in B2B partnerships. That's why we assign a dedicated account manager to every client, who speaks fluent English and is available 24/7 to answer questions or address concerns.
