<p>The present invention provides a manufacturing method of a PET bottle lid. The method includes a melting and blending step, comprising preparing a slurry substantially consisting of polyethylene terephthalate raw material, plasticizer and nano clay; and an injection molding step to mold the lid. Thereby, the lid has enhanced mechanical properties to facilitate follow-up mechanical process. Due to the composition of the lid being highly similar to that of the bottle, the difficulty of recycling PET bottle can be significantly reduced and the cost thereof can also be lowered.</p> |
