Good adhesion resin and curing agent on the PP+PE bottle cap

2020-08-14
Questions: Is there any better adhesive force of resin and curing agent which can be used on our PP, PE bottle caps?
Answer summary:

That is the resin itself is not working. The resin in the entire system should be replaced first.

Cpp resin for cap

iSuo Chem CPP resin, Chlorinated PP

We ever have one customer who have done polyketone resin + elastic rubber resin + CPP resin before. The effect is very good on this type of material of plastics, but the resin compatibility is a little bit worse.

Polyketone resin for cap

iSuo Chem Polyketone resin

So our engineer suggested polyketone resin + chlorinated EVA + CPP resin or polyketone resin + elastic rubber + Chlorinated PE, these two methods will be better with wax powder or abrasion resistant agent.

CEVA for cap

iSuo Chem Chlorinated EVA

Until now, our company can supply TDS and the free samples of Polyketone resin (also called Ketone Resin), Chlorinated EVA (also called CEVA), and CPP resin for your test.
