CumaPET L04 100

Design4Recycling: CumaPET L04 100 top layer
DuFor has developed CumaPET L04 100, which drastically improve recyclability and sealability compared to standard PET grades. When re-extruding APET sheet which is coextruded with a CumaPET L04 100 top layer, the end-product will be completely homogeneous with the same clarity as 100% virgin material. CumaPET L04 100 is characterized by lower melting and glass transition temperatures, which widen the processing window for sealing drastically. Further the packaging which is produced with CumaPET L04 100 is fully recyclable, and of course so is the trimming waste which originates during tray production. 

rPET main layer
When rPET is used for the main layer, the IV is often somewhat lower which results in a higher crystallization rate. If the tray will be recycled, with our L04 100 top layer, the crystallization rate, and thus the clarity of the main layer is improved.

There are also more possibilities to increase the recyclability of your packaging with our other CumaPET types. Interested in our CumaPET L04 100 or other specialty grades please contact us!

Product category: Polyethylene terephthalate (PET)


A typical CPET tray is made of a main layer in combination with a co-extruded top layer to allow sealing of a lidding film. Especially for these layers we are supplying the following materials:

- CumaPET L04 065 top layer
- CumaPET E05 200 & CumaBatch 340 black main layer

Key characteristics
The combination of the above mentioned products will give you the following key characteristics in the end-product:
 Excellent high temperature stability (steam sterilisable)
 High impact resistance at deepfreeze temperatures
 High stiffness
 Food contact approved
 Good barrier properties
 Excellent chemical resistance
 Skeletal waste can be recycled in the main layer

For the production of high quality CPET trays, DuFor offers a complete range of raw materials, please see the added PDF. 

Usage of recycled materials
In addition to the use of virgin materials, we can also offer a solution for the usage of recycled materials. Our grade EcoClear E05 300 green is made of 100% post-consumer bottle flakes and is suitable for the production of CPET. Further information is available upon request. If you are interested in our materials for the production of CPET, please let us know so we can help you determine which material would suit your
application best.

About us

Company portrait

Together we can make the polyester with the best properties your product needs. We develop customized raw materials combined with a high level of technical support. Typical applications for our specialty polyesters are packaging both rigid and flexible, strapping, monofilaments, fibers and other high demanding technical applications. DuFor focuses on developing innovative polyesters that are recyclable and made with renewable resources. 

Customized Raw Materials
Using over 40 years of experience in polymer development and processing in a variety of markets and applications, we are able to translate our customers’ requirements into the recipe of the polymer needed. When the product requires special properties that are not available we develop it together with our customers. We do this by modifying the polymer structure through adding or changing comonomer content, additives, catalysts, changing the molecular weight (IV), compounding, blending or a combination of the before-mentioned. Our goal is to find the perfect polymer formula to meet your needs, from concept to product launch.
