Hen 3 Posted January 9, 2019 I'm needing to cut and press 50 polypropylene bags and not sure which vinyl I need to use. Share this post Link to post Share on other sites
dcbevins 340 Posted January 9, 2019 Never done these bags, but polypropylene is going to melt around 330 F. This stuff has a low press temp compared to others, but have never tried it. Limited colors. https://www.cutterpros.com/specialty-materials-polybag-flex-for-polypropylene-bags I have a bit of brand loyalty gong on with Siser. On one of there forums they state this: Quote Kim Mason December 22, 2017 at 11:31 am - Reply I have polypropylene grocery bags to put a design on. Can I use easyweed on them? Lily December 26, 2017 at 10:36 am - Reply Hi Kim! Absolutely, you can apply HTV to polypropylene. You will need to use a low temperature of 270°-280°F to prevent carrier lines and melting. http://www.siserna.com/heat-apply-htv-heat-sensitive-material/ Maybe someone else has actually done this. 1 Share this post Link to post Share on other sites

I went to http://www.siserna.com/heat-apply-htv-heat-sensitive-material/ and found the answer in the comments. She said that the Siser Easy Weed would work. So I did a test on one of the bags and it worked great! I did 12 seconds at 270 and it didn't stick so I raised it to 280 for 12 seconds and it worked great! 2 Share this post Link to post Share on other sites
