Composition of PET Bottle Bale:



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.

(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 seals

EVA, PP ( floatable material )
PVC or rubber seals are not separable.


Hot melt, water borne.


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

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


Section introduction of PET bottle washing line

1. De-baling Section
De-baling unit adopts weighing-connected feeding device by high automation technology and break up bottle bales and remove mixed metal. The special knife structure can avoid any unexpected mechanical clogging.

2. Sieving Section 
Sieving unit including dry trommel, disk screener and metal removal device to separate some big impurities such as mud, sands and metals from PET bottles and flakes. Meanwhile, through digital technology likes metal detector, pipe-type metal separator, metals can be separated automatically by flapping device to reduce inline manpower. Besides, belt-type metal separator can reach the same function.
3.Label Separation Section
This label separation unit is mainly designed for heat shrinkage label removal.
Label scrapping machine and label blowing machine which wind-force is adjustable.

4.Bottle Pre-washing Section
The primary features of this process are the automated water circulation system, continuous feeding and washing. This system uses special designed inner structure to cause friction for PET bottles inside the machine to remove most of adhesive labels, and uses the high-temperature chemical water to remove dirt, sands, glues, rubbers, metal and other impurities on the surface of bottles.

5.Floatation Section
Secondary washing of PET flakes after crushing is very important. Floatation unit separates PO& PP/PE caps which density is below 1 by using water as the separation media. This unit is comprised by floatation washing and packing silo. It's good to remove caps, rings to keep flakes with stable quality. And impurities of final products can be reduced to 100 ppm or even to 50 ppm.

6.Dewatering Section
De-watering process is running by high-speed mechanical centrifugal force, the moisture content of the flakes will be reduced to be less than 1%. If the heat-exchange air drying is
equipped, the moisture rate of the flakes will be further reduced to be less than 0.8%.

After-sales service
Engineers available to service machinery overseas.
Warranty:1 year for machinery,6 months for electrical.


Q:How do you assistant to install the machine on worksite?
Normally, we send our engineer(s) to supervise the installation and commissioning. The buyer need to prepare the operation staff to implement it. RETECH is able to send mechanical engineer, electrical engineer and operation engineer. The operation engineer is to help the buyer's labors to know how to operate the washing line and get the best efficiency.


Q: How far is your factory from Shanghai?
A: It takes 2~2.5 hours from Shanghai airport to RETECH according to traffic situation.
