BA-137 Marble Pattern and Gold PVD Plated Stainless Steel Vacuum Flask Series | Wholesale Supplier

Elevating the proven “777” brand vacuum flask platform into the premium lifestyle segment, the BA-137 series showcases two sophisticated surface treatment techniques that transform a functional kitchen essential into a decorative statement piece. The water-transfer marble pattern models feature either a black base with gold veining or a white base with grey veining, while the gold PVD electroplated model delivers a mirror-finish luxury aesthetic. All variants share the same reliable spherical body, push-button dispensing, and “HOT & COLD” dual-function标识 that wholesale buyers have come to trust from the 777 product family.

The water-transfer printing (hydrographic) process for the marble pattern models is a multi-step technique that achieves remarkably realistic stone textures on curved metal surfaces. First, a specialized PVA film printed with the marble pattern is floated on the water surface. The flask body is then dipped through the film at a precisely controlled angle and speed, transferring the pattern onto the stainless steel surface. A clear protective topcoat is then applied and cured, providing scratch resistance and ensuring the pattern remains vibrant through years of daily use and hand washing.

The gold PVD (Physical Vapor Deposition) electroplated variant employs a vacuum chamber process where titanium nitride is deposited onto the stainless steel surface at atomic level, creating a brilliant gold finish that is far more durable than traditional gold plating. The PVD coating achieves a hardness of 2000-3000 HV, making it highly resistant to scratching, tarnishing, and fading. This process is environmentally friendly, using no liquid chemicals or heavy metals, and is fully compliant with REACH and RoHS regulations.

The marble texture designs directly respond to the global home decor trend toward natural stone aesthetics that has dominated interior design for the past several years. The black-gold marble variant exudes opulence and is particularly popular in Middle Eastern and Asian luxury markets. The white-grey marble variant offers a more versatile, Scandinavian-inspired look that appeals to European and North American consumers. Both patterns create eye-catching retail displays that command premium shelf positioning and higher price points than solid-color alternatives.

Inside, the BA-137 series maintains the same uncompromising 304 food-grade stainless steel double-wall vacuum insulation that defines the 777 brand. Hot beverages stay above 60°C for over 12 hours, and cold drinks remain chilled for up to 24 hours. The push-button dispensing mechanism, anti-slip black lid, and arc-shaped anti-scald handle are identical to the main BA-136 series, ensuring consistent user experience across the product range while the exterior delivers a dramatically different visual impression.

The primary specification is the 2.0L capacity (Φ14×26cm, ~500g), which represents the best-selling size in the series. This focused approach simplifies inventory management for wholesale buyers while ensuring the most popular configuration is always available. Custom capacity orders (1.5L, 2.5L, 3.0L) are available for larger orders above 300 pieces, allowing distributors to tailor their assortment to specific market preferences.

The “HOT & COLD 777” branding is positioned to complement rather than compete with the premium surface finishes. The label placement is designed to be visible for brand recognition while maintaining the aesthetic integrity of the marble and gold surfaces. This balance between functional branding and decorative appeal is crucial for the gift market, where recipients value both the practical utility and the visual statement of the product.

Wholesale buyers will appreciate the identical packaging logistics to the BA-136 series: each flask in a full-color retail box, 12 units per export carton (55×40×35cm, 16kg GW, 12kg NW). This standardization reduces warehousing complexity and enables mixed orders across both standard and premium series within a single shipment.
