Import 30 Inch Plain & Solid Foil Mylar Balloons — Buy in wholesale FOB from Supplier in China

Wei Sheng Industrial Co., Ltd. supplies 30 inch plain and solid foil mylar balloons in round, heart, and star shapes, with a finished diameter of 78-80cm. The balloons are manufactured from metallised nylon (mylar) film, a biaxially oriented polyester substrate with aluminium vapour deposition that provides helium retention and surface reflectivity. The supplier operates from Longhua District, Shenzhen, in Guangdong Province, and lists direct contact through manager William Zou for wholesale enquiries.

Mylar foil balloons of this calibre typically use nylon-based film with a thickness of 18-22 microns for the body and thicker 25-micron heat-seal layers at the seams to prevent helium diffusion. The plain and solid colour finish indicates uniform pigmentation without printed graphics, suitable for customisation or minimalist event design. Standard colour palettes in the industry include metallic, matte, and pearlised finishes. The 30 inch size category is at the upper end of retail foil balloon specifications, requiring greater inflation precision to avoid overstressing the seal perimeter.

These balloons serve event decorators, party supply wholesalers, corporate promotion agencies, and retail chains sourcing bulk volumes for celebrations and marketing activations. The large format suits venue installations, product launches, and photographic backdrops. Buyers should confirm minimum order quantities, packaging configuration, and helium compatibility directly with the supplier, as these trade terms are not stated in the listing.

Wei Sheng Industrial Co., Ltd. is located in Huixin A Building, Longhua District, Shenzhen, 518109, Guangdong Province, China. The supplier operates under a harbor trust tier with a response rate of 0.00% and zero recorded average response hours, which indicates no response history is available through the platform. The listing provides direct manager contact via Skype, QQ, WeChat, Line, and WhatsApp, suggesting the supplier prefers off-platform communication for negotiations and order confirmation.

The source description identifies William Zou as manager and gives a mobile number starting with 0086-134. No factory size, year of establishment, certification, or production capacity is stated. The company name also appears as 'Wei sheng industrial co., limited' in the source text, a common registration format for export-oriented manufacturers in Shenzhen. Buyers should verify business registration, export licence, and quality management credentials directly with the contact provided before committing to volume orders.
