Rubber inflatable airbag also known as roller bags or ship launching balloon, are made of heavy-duty synthetic-tire-cord layers with inner and out rubber layers in long cylindrical balloon shape. Ship launching airbags can be used for the ship launching or ship landing of tanker, tugboat or barges, carrying vessel, carrier, ferry and other special vessels and so on.
Rollers Bag is a innovative ship launching technology, comparing with "end-on launching", "side ship launching", "float-out".

Synthetic-tire-cord layer is reinforcement layer of the ship launching airbags which are made of rubber coated synthetic-tire-cord fabrics. Many synthetic-tire cord layers are twined at ideal angles by unique and patented “Holistic Wrapping Technology“. To hold the internal pressure and to distribute the stress evenly. external forces. This compound has sufficient tensile and tear strength to withstand any weather condition and hard usage.
