Corrugated Double Wall Insulated Cup Factory Direct Custom Logo Durable Heatproof

Say goodbye to burnt hands and flimsy cups. This cup delivers both temperature control and structural strength. Featuring a thickened double-wall hollow insulation structure combined with an outer deep 3D corrugated texture, thermal resistance is taken to the next level. In tests, when filled with a 95°C hot beverage, the outer wall temperature remains at ≤38°C (approximately 15°C cooler than standard single-wall cups). No sleeve needed—comfortable to hold, eliminating the common frustrations of slipping sleeves, grease stains, and awkward one-handed gripping. The cup wall is thickened by 15%, with a basis weight 1.5 times that of conventional cups. Even when filled to the brim with bubble tea or a large serving of iced slush, the cup stays rigid and does not collapse, solving the problems of easy crushing, lid popping, and leakage. Full size range covers from 6oz mini tasting cups to 32oz extra-large sharing cups, meeting the needs of any beverage brand’s full product line.

Made from food-grade virgin PP-coated paper, heat-resistant to 120°C, with no fluorescent brighteners and no odor. Certified to both GB 4806.8 and FDA 21 CFR 176.170 food safety standards. The inner coating is uniform and dense, resisting oil, acid, and puncture – safe for thick cheese foam, lemon fruit teas, or hot chocolate without any penetration or softening. Cup stiffness has been professionally tested via ring crush tests; both longitudinal and transverse compression values exceed national standards by over 30%. Stacked storage does not cause deformation, saving space and ensuring safe transport. The same strict quality control system applies across all sizes – from the 6oz mini to the 32oz sharing cup – with zero variation in quality.

The raised texture is not just decorative; it delivers three practical functions simultaneously.

1. Thickened Air Insulation Layer
The corrugated grooves create a static air cavity between the outer texture and the inner wall. Utilizing the low thermal conductivity of air, heat transfer to the outer surface is effectively slowed, improving insulation efficiency by approximately 10% over standard double-wall cups. Whether it’s a 6oz hot espresso or a 22oz large hot latte, the grip remains comfortably warm.

2. All-Directional Anti-Slip System
The deeper texture substantially increases the coefficient of friction. Whether dry hands, wet hands, or condensation from iced drinks, the cup stays securely in hand. Delivery riders navigating bumpy roads and customers walking and drinking can both enjoy peace of mind. For larger diameters (24–32oz), where the cup is heavier, the anti-slip design is particularly critical – the corrugated texture provides extra reassurance.

3. Structural Reinforcement Skeleton
The corrugated ribs act as longitudinal stiffeners, enhancing the cup’s compressive strength from a structural standpoint. It resists crushing and deformation, and when stacked for delivery, the lower cups remain intact. For larger capacities, where the filled weight is greater, the reinforcing effect of the thickened corrugation is especially pronounced.

The cup rim features a thickened rolled edge, smooth and non-abrasive to the lips, enhancing drinking comfort. The base incorporates a reinforced inward-curved design for stable placement without tipping, and prevents residual table moisture from seeping into the cup bottom. Paired with high-seal leak-proof lids (options include PS high-clarity hard lids, PET easy-tear lids, flat lids, and dome lids, matched per size), the lid and rim engage with precision locking. Triple-tested (90° tilt, light squeeze, and upside-down shake), the leakage rate is zero. A micro-vent hole on the lid balances internal and external pressure, preventing hot beverage lids from popping off or making it difficult to insert a straw for cold drinks. For larger sizes (20oz and above), reinforced lids with wider and thicker locking mechanisms are available for upgraded seal integrity.

One thickened corrugated cup directly replaces the traditional "cup + sleeve" combo, reducing paper consumption and waste generation by approximately 30% at source. The outer corrugated paper is made from FSC® certified sustainably managed pulp, ensuring traceable, renewable, and legal raw material sourcing. The inner coating can be customized with water-based non-plastic coatings or PLA bio-based degradable coatings to support your brand’s ESG commitments. Packaging is also optimized – because no sleeves are required, each carton holds about 20% more cups, lowering per-unit shipping carbon footprint and warehousing costs. Sustainability is covered across all sizes – from 6oz tasting cups to 32oz large sharing cups – enabling unified green packaging for your entire product line.

The deepened corrugated texture offers a distinctly more pronounced tactile sensation compared to standard corrugation. When fingers press against it, there is a clear elastic feedback that unconsciously creates a memorable brand impression. The cup body features a subtle ergonomic waistline that better fits the natural grip of Asian hand sizes, allowing even smaller hands to hold larger sizes (24–32oz) with greater ease and stability. For custom printing, the corrugated grooves can showcase 3D UV embossed effects or hot stamping (gold/silver), where the brand logo catches light from different angles to create dynamic shadows – delivering a visual depth far beyond conventional flat printing. The same design language across all sizes ensures brand consistency throughout the product range. When customers take photos and share them on social media, the unique cup texture naturally becomes the focal point, providing free secondary brand exposure.

Premium café third-wave takeaway (6–12oz espresso to standard cups), modern tea beverage full range (16–22oz milk teas and fruit teas), winter hot drink pop-ups, summer iced coffee stations, camping and picnics (large sharing sizes), art collaboration exhibitions, corporate office tea breaks (mini tasting cups), hotel lobby bars, conference events, cinema beverage counters, convenience store coffee stations, gym juice bars – in every scenario, from 6oz mini samples to 32oz mega shares, the thickened corrugated cup delivers stable physical performance and distinctive visual appeal, carrying both brand warmth and beverage quality.

For orders of 1,000 pieces or more, we can print your brand logo with UV full-color printing – high color saturation, abrasion-resistant and fade-proof. For orders of 3,000 pieces or more, we offer special processes including hot stamping (gold/silver), partial tactile varnish, spot colors, and embossed debossing. Custom artwork and samples are welcomed. Free digital samples are provided for approval. Bulk orders are delivered within 15–20 working days after confirmation. Professional packaging uses thickened 5-layer corrugated cartons with interlayer partitions to ensure cup integrity during transit. We support mixed-size orders for flexible procurement, satisfying one-stop purchasing for your entire product line.
