The answer lies in the Sink-float separation tank, a masterclass in applying basic physics to industrial challenges. The principle is density separation. PET has a density of ~1.38g\/cm\u00b3, causing it to sink in water. Conversely, PP and PE have densities less than 1.0g\/cm\u00b3, allowing them to float. In our high-capacity PET bottle washing line, the flakes are agitated in the tank. The &#8220;sinkers&#8221; (pure PET) are collected by a screw conveyor at the bottom, while the &#8220;floaters&#8221; (labels and caps) are skimmed off the surface. To achieve the highest PET flake purity, we recommend a multi-stage [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":8719,"parent":0,"template":"","tags":[134],"info-type":[3],"class_list":["post-8718","info","type-info","status-publish","has-post-thumbnail","hentry","tag-pet","info-type-knowledge-base"],"taxonomy_info":{"post_tag":[{"value":134,"label":"PET"}],"info-type":[{"value":3,"label":"Knowledge Base"}]},"featured_image_src_large":["https:\/\/www.recycle-plant.com\/wp-content\/uploads\/2026\/02\/Sink-Float-Separation-Tank-Works.webp",720,540,false],"author_info":{"display_name":"Ella","author_link":"https:\/\/www.recycle-plant.com\/ja\/author\/admin\/"},"comment_info":"","_links":{"self":[{"href":"https:\/\/www.recycle-plant.com\/ja\/wp-json\/wp\/v2\/info\/8718","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.recycle-plant.com\/ja\/wp-json\/wp\/v2\/info"}],"about":[{"href":"https:\/\/www.recycle-plant.com\/ja\/wp-json\/wp\/v2\/types\/info"}],"author":[{"embeddable":true,"href":"https:\/\/www.recycle-plant.com\/ja\/wp-json\/wp\/v2\/users\/1"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.recycle-plant.com\/ja\/wp-json\/wp\/v2\/media\/8719"}],"wp:attachment":[{"href":"https:\/\/www.recycle-plant.com\/ja\/wp-json\/wp\/v2\/media?parent=8718"}],"wp:term":[{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.recycle-plant.com\/ja\/wp-json\/wp\/v2\/tags?post=8718"},{"taxonomy":"info-type","embeddable":true,"href":"https:\/\/www.recycle-plant.com\/ja\/wp-json\/wp\/v2\/info-type?post=8718"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
