Background
Following the visit at Uralplastic the 18th of February, I came back with
3 samples:
1/. Peel to PS: they used for this 3 Appeel® grade 11D554, 20D855 and
20D751, they didn’t have a good peel at 170-180°C and the peeling is
not stable. Generally the structure is: 20% / 50% / 30%
(Appeel®:10microns)
2/. Second point of discussion the Appeel®72D811, they are looking
for something for PET/Pe and PVC/PE trays, they have produced a
film of Appeel®72D811 with 3% of Conpol 20S2 and 2% of Conpol 20B.
We will performe some analysis on this one.
3/. Others topics: Appeel®93D894 and also tie layer in presence of AF
recommandation Bynel®4109, proposition of used of Surlyn 1605 to
avoid leackers on the corner of trays.

Objectives:
1/ For the 2 structures with Appeel®20D855 and Appeeel®11D554,
measure the adhesion strenght on PS between 160 to 210°C.
2/ For the structure with Appeeel®72D811, the analysis will be the
control of the thickness of each layer and also the measure of peeling
on PE between 120 and 180°C.

With the Appeel® 20D855 after 160°C , the film Break so the adhesion

Summary
For the Appeel® 11D554 and 20D855, we observe that the adhesion is very high
for the 20D855.
And for the third film with Appeel®72D811, we confirm the structure and thisckness,
and also the adhesion on PE was perfomed.
