Your Trusted Partner for Custom Plastic Packaging Solutions Since 2005
Let's start with a scenario many of you might relate to: You've spent months perfecting your new organic shampoo formula—testing ingredients, tweaking scents, and nailing that creamy lather. Now it's time to package it, and you need a disc top cap that not only looks sleek on the bottle but also keeps the product fresh, doesn't leak in transit, and aligns with your brand's eco-friendly values. Sound familiar? As a custom plastic bottle manufacturer with over 18 years in the industry, we've heard this story hundreds of times. And it's why we built our entire operation around solving exactly these kinds of challenges.
At MGG Packing, we're not just another supplier—we're your packaging partner. Based in Guangdong, China's manufacturing heartland, we specialize in crafting high-quality disc top caps and closures for cosmetic, personal care, and pharmaceutical brands worldwide. What sets us apart? Our GMP-compliant dust-free workshops, ISO 9001-certified quality control, and a team that treats your project like it's our own. Whether you're a startup launching your first product line or a multinational brand scaling production, we've got the expertise and infrastructure to deliver—on time, on budget, and beyond expectations.
You might be thinking, "It's just a cap—how important can it be?" Trust us, we've seen brands lose customers over a faulty closure. A disc top cap is the first thing your customer interacts with when they pick up your product. It needs to open smoothly (no struggling with stiff lids!), dispense the right amount of product (no messy drips!), and seal tightly to prevent contamination. For cosmetic and personal care brands, it's also a key part of your brand identity—think of that sleek black disc top on your favorite lotion bottle or the matte finish that matches your minimalist packaging.
Fun fact: In a recent survey we conducted with 200 cosmetic brands, 68% said packaging closures were the most common customer complaint they received. Leaks, hard-to-open caps, and broken hinges topped the list. That's why we focus so intensely on the details—because we know your reputation depends on it.
Our disc top caps are designed to solve these pain points head-on. Let's break down what makes them stand out:
We use only food-grade PP (Polypropylene) and HDPE (High-Density Polyethylene) for our caps—materials that are BPA-free, non-toxic, and resistant to chemicals, heat, and impact. This isn't just about meeting regulations (though we do that, too); it's about ensuring your product stays pure from the factory to the customer's bathroom shelf. For example, our HDPE caps are perfect for oil-based products like serums or hair treatments, while PP caps offer a smoother finish for premium skincare lines.
Ever had a bottle of conditioner leak in your suitcase? Not fun. Our caps feature a dual-seal system: an inner silicone gasket that conforms to the bottle neck and an aluminum foil liner (optional) for an extra barrier against moisture and air. We test every batch under 3 different conditions—temperature extremes (-20°C to 60°C), pressure changes, and vibration—to mimic real-world shipping and storage. The result? A closure that's 99.9% leak-proof, even for thin liquids like facial mists or runny lotions.
Your packaging should tell your brand's story, and your cap is no exception. We offer endless customization options to make your disc top caps uniquely yours:
We know every product is different, which is why we offer a wide range of disc top cap sizes and styles to fit almost any bottle. Below is a quick overview of our most popular options—think of it as your cheat sheet for finding the perfect cap for your needs:
| Cap Size (Neck Finish) | Material | Sealing Option | Best For | Minimum Order Quantity |
|---|---|---|---|---|
| 20/410 | PP/HDPE | Silicone gasket | Small bottles (30-60ml): serums, travel-size shampoos | 5,000 units |
| 24/410 | PP/HDPE | Silicone gasket + aluminum foil liner | Standard bottles (100-250ml): body wash, conditioner, hand soap | 3,000 units |
| 28/410 | HDPE (heavy-duty) | Double silicone gasket | Large bottles (500ml+): household cleaners, salon-size products | 2,000 units |
| 24/415 (Tall Thread) | PP | Moisture-proof liner | Thick formulas: lotions, creams, hair masks | 5,000 units |
But these are just the basics. Need a custom size? No problem. Our in-house mold design team can create a unique neck finish or cap shape tailored to your bottle. We've even designed caps with built-in applicators (think a soft silicone brush for face masks) and flip-top lids with hidden mirrors for on-the-go touch-ups. The only limit is your imagination!
Our caps are trusted by brands across the globe, from indie beauty startups to Fortune 500 companies. Here are just a few examples of how our clients use them:
Let's be honest—there are plenty of plastic packaging suppliers in China . So why choose us? Here's what our clients tell us keeps them coming back:
We're proud to hold both ISO 9001:2015 (for quality management) and GMP (Good Manufacturing Practice) certifications. What does that mean for you? It means every step of our process—from raw material sourcing to final inspection—is documented, audited, and continuously improved. Our dust-free workshops (Class 100,000) ensure no contaminants touch your packaging, which is especially critical for pharmaceutical and sensitive cosmetic products. You can even request a copy of our latest audit report—we're transparent about our standards because we have nothing to hide.
Ever tried to explain a unique cap design to a supplier and gotten blank stares? We've been there, which is why we built a full in-house mold design and manufacturing team. Here's how it works:
Client Spotlight: Last year, a US-based skincare brand came to us with a problem: their current disc top caps kept breaking at the hinge after a few uses. They needed a solution in 10 days to meet a major retail launch. Our team redesigned the hinge with reinforced ribs, tested 3 prototypes in 48 hours, and delivered 50,000 custom caps in 9 days. Their launch was a hit, and they're now one of our biggest repeat clients. Stories like this are why we love what we do.
As a B2B plastic container wholesaler , we cut out the middlemen—meaning you get factory-direct pricing with no markups. We also keep over 1 million standard disc top caps in stock, so for non-custom orders, we can ship in 3-5 days. For custom projects, our production lines run 24/7, allowing us to fulfill orders of up to 10 million units per month. And with our partnerships with major logistics companies (DHL, FedEx, sea freight), we can deliver to almost any country in 5-30 days, depending on your needs.
We know sustainability is no longer a "nice-to-have"—it's a business imperative. That's why we offer a range of eco-friendly solutions, including:
We're also working on biodegradable options (stay tuned for our PLA-based caps launching next quarter!) because we believe sustainability shouldn't mean sacrificing quality.
Don't just take our word for it—here's what some of our long-term clients have to say about working with us:
"We've been partnering with MGG for 5 years, and their disc top caps are the backbone of our packaging line. What I love most is their responsiveness—when we needed to change a cap color for a limited-edition product, they turned it around in 3 days. You won't find that kind of service with big suppliers." — Sarah, Founder of Glow Organics (US-based skincare brand)
"As a pharmaceutical company, compliance is non-negotiable. MGG's GMP workshop and detailed quality reports give us peace of mind. Their child-resistant disc top caps have never failed a safety test, and their team always goes the extra mile to explain technical specs in plain English." — Raj, Procurement Manager at MediCare Pharma (India)
"We started with 10,000 units and now order 500,000 caps per month. The consistency is impressive—every batch looks and functions exactly like the last. Plus, their PCR caps have helped us reduce our carbon footprint by 22%." — Carlos, Operations Director at BeautyCo (Brazilian cosmetic distributor)
At the end of the day, your packaging is an extension of your brand. It should protect your product, delight your customers, and reflect the care you put into everything you do. As a custom plastic bottle manufacturer and ISO 9001 certified packaging factory , we're here to make that process as smooth and stress-free as possible.
Whether you need standard disc top caps in bulk, custom-designed closures, or help navigating sustainability options, we're just a message away. Here's how to get started:
