Polypropylene Bags – the do’s and don’ts for heat transfer application
Polypropylene bags are made from the synthetic plastic polymer polypropylene, used in bags because it is strong, flexible, and reusable. They lend themselves to a wide variety of uses, both for consumers and businesses alike. They are most popularly used as an alternative to disposable bags for shopping, moving, and storage. Additionally, these bags are widely used as promotional products for giveaways at events, or as thank yous to your loyal customers.
We have a few tips and tricks for printing on these bags that are naturally heat sensitive due to their plastic-based fabric.
Here are do’s and don’ts for decorating polypropylene fabric:
Do decorate Polypropylene tote bags
Polypropylene bags are an inexpensive promotional item that can be decorated with traditional printing methods like screen printing. They are also able to be heat printed on your heat press.
Don’t heat print Polypropylene at high temperatures
Polypropylene tote bags should be pressed at a low temperature setting. Choose a type of heat transfer that has a low heat press application. These bags should not be pressed any higher 275 degrees without experiencing some melting of the fabric. Some transfers that heat at 300 degrees may be used, however some bags may experience minor melting at this temperature.
Do use Elasti Prints® or Stretch Litho™ screen printed transfers.
Do Raise the Print area
As with any other type of tote bag or cinch sack, be sure to create a flat and even surface for heat printing your design. Thick seams, zippers, buttons, strings and straps will need to be moved away from the printing area. If needed, use an interchangeable platen for your heat press or raise the print area with a mousepad or Print Perfect Pad for a flat, even, firm surface.
Don’t be afraid to decorate Polypropylene tote bags
Polypropylene bags can be intimidating and scary to decorate for the first time on your heat press. Just remember to keep the temperature low and you will avoid a messy, melted bag.
