China Top 8 Silicone Cup Lid Producers for Wholesale Straw Hole Covers

If you are in the drinkware business—whether you are distributing stainless steel bottles in Canada or selling branded tumblers on Amazon US—you have likely noticed a massive shift in the market. It’s not just about the bottle anymore; it’s about the accessories.

Specifically, the demand for silicone cup components like straw hole covers, spill-proof stoppers, and lid gaskets¹ has exploded. This is largely driven by the popularity of large travel tumblers (like the Stanley Quencher) where spills are a major pain point for end-users. As a business owner, you need these small, high-margin silicone items to upsell your core products or solve a functional problem for your customers.

But here is the challenge: finding a reliable manufacturer in China who understands FDA/LFGB compliance², offers precise molding for leak-proof fits, and doesn’t vanish when you need after-sales support.

I am Aries Hua, the founder of Silijoy. With over 10 years of experience in silicone manufacturing right here in Zhejiang, I have seen the good, the bad, and the ugly of the supply chain. I understand that buyers like you—seasoned veterans who value transparency and efficiency—don't have time to sift through thousands of trading companies on Alibaba. You want factory-direct partners.

To help you streamline your sourcing, I have compiled a list of the Top 8 Silicone Cup Lid and Straw Cover Producers in China. This list is based on manufacturing capabilities, export experience to North America and Europe, and reputation for quality control.

1. Silijoy (Zhejiang)

Website: https://silijoy.com
Location: Zhejiang Province, China
Business Type: Manufacturer (OEM/ODM)

I am putting Silijoy first not just because it is my business, but because our entire production model is built around the specific needs of B2B wholesalers in the drinkware accessory niche. Unlike massive factories that treat small silicone accessories as an afterthought, we specialize in them.

We focus heavily on the "pain points" of drinkware. Whether it is a silicone boot to stop a bottle from denting or a custom-molded straw hole cover³ to prevent leaks in a tumbler, we have the molds and the expertise ready to go.

Why Wholesalers Choose Silijoy:

• Specialized Expertise: We produce millions of silicone straw toppers⁴, straw plugs, and lid gaskets annually. We understand the precise shrinkage rates of silicone, ensuring that the straw cover fits tightly and doesn't fall off—a common quality issue with cheaper competitors.
• Material Safety: For the Canadian and European markets, safety is non-negotiable. We use 100% food-grade silicone⁵ that is BPA-free and LFGB certified. We can provide raw material test reports before you even place a bulk order.
• Design to Production: If you have a rough sketch of a custom straw cover (perhaps a specific logo shape or animal design), my team handles the 3D rendering, prototyping, and mold creation in-house.
• Low MOQ & Fast Samples: I know you need to see the quality before committing. We offer free samples for quality reference and keep our Minimum Order Quantities flexibility to support growing brands.

If you are looking for a partner who acts as an extension of your own team—providing technical advice rather than just taking orders—Silijoy is your best fit.

2. Dongguan Oumeng Houseware Products Co., Ltd.

Location: Dongguan, Guangdong
Business Type: Manufacturer

Dongguan is known as the "World's Factory," and Oumeng is a significant player in the plastic and silicone houseware sector. While they are very famous for their Bento Boxes, they have expanded extensively into drinkware accessories.

Key Features:

• They have a massive production capacity suitable for Walmart-level orders.
• Their location in Dongguan gives them access to a sophisticated supply chain for packaging materials.
• Pros: Great for massive volume orders where price is the only factor.
• Cons: Because they are so large, communication can sometimes be impersonal. Small to medium custom projects (like a specific straw cover design) might not get the priority attention they deserve compared to their massive bento box orders.

3. Huizhou Melikey Silicone Product Co., Ltd.

Location: Huizhou, Guangdong
Business Type: Manufacturer

Melikey is a strong competitor that originally started in the "Baby & Mom" niche (teethers, pacifiers, beads). However, the manufacturing process for a silicone baby teether is nearly identical to that of a silicone straw cover or cup lid.

Key Features:

• High Safety Standards: Because their background is in baby products, they are extremely strict about FDA and LFGB compliance. Their clean rooms are often top-tier.
• Molding Capability: They excel at multi-color silicone injection, which is useful if you want straw covers that have intricate, multi-colored designs without fading.
• Suitability: Excellent choice if your brand leans heavily towards the "Cute/Mom/Baby" aesthetic for your drinkware accessories.

4. Shenzhen Benhaida Rubber & Plastic Products Co., Ltd.

Location: Shenzhen, Guangdong
Business Type: Manufacturer

Shenzhen Benhaida is a veteran in the silicone kitchenware industry. If you have searched for silicone products on Alibaba, you have likely seen them. They have been exporting to the US and Europe for over a decade.

Key Features:

• Vast Catalog: They have thousands of "open molds." This means if you are looking for a generic silicone cup lid or a standard round straw cover, they likely already have the mold, saving you the setup fee.
• Logistics: Located in Shenzhen, they have immediate access to one of the world's busiest ports, which can sometimes shave a day or two off shipping times.
• Caveat: Because they have so many open molds, their designs are very common. If you are looking for a unique, custom-branded product to differentiate yourself in the Canadian market, you will need to pay for private molding.

5. Fujian Jibang Electronic Co., Ltd.

Location: Quanzhou, Fujian
Business Type: Manufacturer

Fujian province focuses heavily on promotional gifts and electronics, but they have a strong silicone sector as well. Jibang is known for integrating silicone with other materials.

Key Features:

• Cost-Effective: Generally, labor costs in Fujian can be slightly lower than in Shenzhen, which might be reflected in a lower unit price for high-volume, simple items.
• Promotional Focus: They are excellent at silk-screen printing on silicone⁶. If you need 50,000 straw covers with a simple company logo printed on them for a trade show giveaway, they are a solid option.
• Quality Note: Be sure to specify your hardness and material requirements clearly to ensure the "feel" matches premium drinkware standards.

6. Ningbo Yinzhou United Plastic Industrial Co., Ltd.

Location: Ningbo, Zhejiang
Business Type: Manufacturer

Located near us in Zhejiang, this factory focuses heavily on the hard plastic components of tumblers but supplies the accompanying silicone gaskets and lids.

Key Features:

• Integrated Solutions: If you are looking to buy the entire lid (the hard plastic screw-top + the silicone sealing ring + the silicone straw cover), they are a good one-stop-shop.
• Port Access: Ningbo port is one of the largest in the world, ensuring excellent logistics for heavy sea freight shipments.
• Focus: They are less focused on the "cute" accessory market (like animal-shaped straw toppers) and more on the industrial/functional side of lid manufacturing.

7. Xiamen Xinxing Silicone Rubber Co., Ltd.

Location: Xiamen, Fujian
Business Type: Manufacturer

Xinxing is a high-tech enterprise. They focus on Liquid Silicone Rubber (LSR) injection molding. This is a more advanced process than standard compression molding.

Key Features:

• Precision: LSR molding creates products with very minimal flash (excess material) and extremely tight tolerances. This is perfect for "Tumbler Seal Rings" and O-rings where a 0.1mm difference can cause a leak.
• Durability: LSR products generally have better tear resistance and clarity than compression-molded standard silicone.
• Cost: The tooling (molds) for LSR is significantly more expensive than standard compression molds. This option is best for mature brands ordering 50,000+ units who need aerospace-level precision.

8. Dongguan Invotive Plastic Product Co., Ltd.

Location: Dongguan, Guangdong
Business Type: Manufacturer

Invotive is an aggressive, design-forward manufacturer. they are often seen at trade shows and invest heavily in R&D for trendy silicone products.

Key Features:

• Trend Awareness: They are very quick to copy or adapt to TikTok trends. If a new style of "Stanley Cup Snack Bowl" or "Cloud Straw Cover" goes viral, they usually have a mold ready within weeks.
• Packaging: They offer sophisticated retail packaging options, which saves you from having to repackage goods upon arrival in Canada.
• Communication: They have a large sales team with decent English proficiency, making the initial inquiry process relatively smooth.

How to Choose the Right Partner?

Mark, based on the profile of a successful distributor like yourself, you know that the "cheapest" price is rarely the "best" price. When sourcing silicone cup lids and wholesale straw hole covers, you are actually buying three things:

1. The Material: It must be food-grade and odor-free. Cheap silicone smells like chemicals.
2. The Function: The cover must fit the straw snugly. Loose covers lead to leaks and bad Amazon reviews.
3. The Service: You need a transparent timeline and honest updates on production.

While the Guangdong giants (Shenzhen/Dongguan) are great for massive general orders, and Fujian is good for promotional items, Zhejiang manufacturers like Silijoy provide the sweet spot. We offer the manufacturing sophistication of the south with the cost-efficiency and direct service culture of the east.

Conclusion

Sourcing the right silicone accessories can make or break the user experience of the drinkware you distribute. While all 8 companies on this list are capable producers, your choice depends on whether you prioritize massive generic volume or high-quality, customized precision.

At Silijoy, we combine over a decade of manufacturing expertise with a specific focus on OEM drinkware accessories. We understand the North American market's demand for safety certification and the rigorous quality control required by Canadian distributors.
