i did melted a lot of hdpe and from experience hdpe when melted will not turn liquid it will be more like thick taffy if you want it to be completely flat you could clamp it down between two boards while still melted this way your plastic will be completely flat. and keep in mind that not all hdpe is the same because most containers like the ones you used in the video are blow molded and blow molded hdpe is higher density which makes it less flowable when melted on the other hand 5 gallon buckets are normally injection molded which uses a lower density type of hdpe that flows into the mold without pressure however the higher density hdpe is stronger
