As we are developing both PLA and Recycled PET, some of you may wonder what are the differences between them. Now we summarize the major differences below. I also added other common materials melamine and plastic PP for more comprehensive comparison. Here is the differences introduction between Recycled PET and PLA and Melamine

4 Material Performance Competition

 

Character: PLA Recycled PET(RPET) Melamine PP Plastic
 

 

Temperature

Resistance:

 

 

-20℃-100℃

 

 

-20℃-140℃(without IML print)

 

 

-30°C~120°C

 

 

20℃-120℃

 

 

Microwave:

 

 

400Wmax and 3mins at most

 

 

Yes

 

 

Not recommend

 

 

Yes

 

 

 

Dishwasher:

 

 

 

Yes

 

 

 

Yes

 

 

 

Yes

 

 

 

Yes

 

 

Print:

 

 

1C print

4C heat transfer print

 

 

 

1C print

4C heat transfer print

IML print

 

1Cprint

Decal for 4C print

 

1C print


4C transfer print

IML print

 

 

 

Printing Plate and Cost:

 

Heat transfer print needs the printing plate. Printing plate charge is calculated on colors and more expensive than Decal print plate

 

 

 

Heat transfer and IML print require printing plate. Printing plate charge is calculated on colors and more expensive than Decal print plate

Decal needs a printing plate.
Cost is less expensive and flexible
 

 

Heat transfer and IML print both require printing plate. Printing plate charge is calculated on colors and more expensive than Decal print plate

 

Mold and Cost:

 

Injection mold with extra crystallization step; 2mins for each injection. Low production efficiency(Mold cost is nearly same with Mold for RPET)

 

Injection mold

(Mold steel is high standard and more expensive than other plastic. Development cost is higher. Nearly same with PLA mold)

Press Mold

Cost is less expensive than Injection mold

 

Normal Injection Mold (Cost is higher than Melamine press mold but less expensive than RPET mold and PLA mold)

We have listed up differences between Recycled PET and PLA and Melamine. But this is our understanding about the materials. If you have any questions regarding the differences, please let me know freely. We would like to discuss. Contact here.
