Based on more than 20 years experience we BORETECH provide all output capacity PET bottle recycling line & technial support
PET Bottle Recycle Line
Key Word: PET bottle recycle line, 500 kg/h PET bottle recycling line, 500 kg/h PET flake produce line
Designed Capacity: 500 kg/h~6000 kg/h
*The Process Flow Depend on the Bottle Material Input. there are different Process Flow design between 500 kg/h ~6000 kg/h
Basically the standard process design as below:
De-baling------ Label Scrapping------- Label Separation-------- Persorting------Bottle Pre-washing ------ Manual Sorting and Metal Detecting-----Wet Grinding-------Gravity Separation-------Chemical Washing for PET Flakes-------Rinsing--------Drying--------Packing
Description :
The Process is used to recycle big capacity and stable quality raw material, especially for PSF manufacturer and recycled POY manufacturer with big capacity.
Composition of PET Bottle Bale
Description
Characteristic
PET Containers
One-way bottles
Colors Fraction
PET bottles should be pre-sorted by color. If the percentage of color bottles is higher than 30%, we suggest customer to install the automatic color bottle sorting machine to achieve efficiency.
Base Cups
Included, if any, and should be PP or PE plastic.
Labels
(shrunk or glued)
The production line is designed for removing label mechanically. All type of labels will be removed by mechanical action. It includes paper, BOPP, PET, PVC, etc.
Caps
PP, HDPE
Caps seals
EVA, PP ( floatable material )
PVC or rubber seals are not separable.
Glue
Hot melt, water borne.
Contamination
Mixed with the bottles could be present contaminations coming from the collection and storage of the postconsumer bottles or made by consumer. These contaminations include mud, sand, soil, glass, organics, paper, residual liquid, etc.
Total contamination content should not exceed 10%.
Total Non-PET
Containers
Non-PET containers max 2% of which
PVC Container
0.5 -1% max
Polyolefins Container
3 % max. It will only affect the output volume but not quality of end product.
Wrong PET Colors
and Opaque
1-2% max
Glass and Ceramic (metals excluded)
0.5 -1% max
Magnetic Metals
0.5 - 1% max
Aluminum and Non Magnetic Metals
0.5 - 1% max
All kind of metal will be separated before crushing
