The invention discloses a fast replaced strip-shaped inner tube which is provided with two end heads, wherein the two end heads are sealed. The fast replaced strip-shaped inner tube disclosed by the invention is characterized by being made from a PVC material, and the PVC material comprises the following components in parts by weight: 45-49 parts of PVC polyvinyl chloride paste resin, 45-49 parts of dioctyl phthalate, 1-2 parts of PVC heat stabilizers and 0-5 parts of other addition agents. Because the PVC material is adopted, a rotational moulding process can be adopted, namely, firstly a powder or paste or monomer material is injected into a mould, the material is uniformly distributed in an inner cavity of the mould under the action of self gravity and is melted by heating, rolling and rotating the mould, and the material is demoulded after being cooled so that the strip-shaped inner tube is made.
