The Future of Double Layer Paper Cups

     The temperature profile of a perfect cup of coffee requires care from extraction to serving. In the future, the Double Wall Paper Coffee Cups range will be precision engineered to keep every sip in the optimum flavour zone.

      Double Wall Takeaway Coffee Cups can be built on the NASA spacecraft insulation principle, creating a vacuum barrier between the two layers of paper. 0.2mm air layer with aluminium foil reflective film reduces the rate of heat loss by 67%. Tested by SCA certified laboratory, after injecting 92℃ hand-brewed coffee, the temperature inside the cup remains above 58℃ after 1 hour, perfectly covering the three-stage experience of coffee flavour. The mouth of the cup is specially hardened, with a thickness of only 0.8mm, but can withstand 500 lip contacts without deformation. The unique design of 'wave anti-scald ring' forms 32 micron-sized concave-convex lines on the cup body, which not only increases the friction of holding, but also accelerates the heat dissipation by enlarging the surface area, ensuring that the first sip of the coffee falls at the ideal entry temperature of 62℃.

       Double Wall Disposable Coffee Cups For high-pressure espresso, the lid has an integrated 'pressure regulator'. When the espresso is piping hot, the valve automatically opens to release the steam pressure and prevent the liquid from splashing; after 30 seconds of resting, the valve closes and switches to keep-warm mode. This technology extends the preservation time of the crema layer of espresso to 8 minutes, far exceeding the industry average of 3 minutes. The specially designed 'Flavour Ruler' at the bottom of the cup indicates the optimal drinking temperature range through a ring code of different colours: red represents the latte zone of 55-65°C, and blue corresponds to the Americano zone of 60-70°C. The barista can quickly check the temperature of the espresso according to the type of drink. Baristas can quickly match the cup shape to the type of drink to ensure complete flavour transfer.

      The double-layer cup is made of bagasse and bamboo fibre composite material, which reduces the carbon footprint by 42% compared to traditional paper cups. A separate recycling system can be introduced: the outer body can be composted, while the inner waterproof membrane is recycled separately for plastic pellets. The use of this system by coffee shop chains has reduced waste disposal costs by an average of 28 per cent.
