Can you use Thermography on Recycled Polypropylene?

Feasibility of Thermography on Recycled Polypropylene

Thermography is a printing technique that involves the application of heat to create a raised effect on the printed surface. When it comes to recycled polypropylene, a common type of plastic, the feasibility of thermography is somewhat limited. Polypropylene has a relatively low melting point, which can make it challenging to use with high-heat printing techniques like thermography. However, with careful control of the heat application, it is possible to use thermography on recycled polypropylene.

Is Thermography on Recycled Polypropylene Advised?

While it is technically feasible to use thermography on recycled polypropylene, it is not generally advised. The low melting point of polypropylene means that there is a high risk of damaging the material during the printing process. Additionally, the heat from thermography can cause the polypropylene to warp or deform, which can negatively impact the quality of the final printed product.

Better Printing Techniques for Recycled Polypropylene

Given the challenges associated with using thermography on recycled polypropylene, other printing techniques are typically recommended. One such technique is pad printing, which involves transferring an image from a plate to the polypropylene surface via a silicone pad. This method is gentle on the material and can produce high-quality prints. Another option is screen printing, which uses a mesh to transfer ink onto the surface of the polypropylene. This method is also gentle on the material and can produce vibrant, long-lasting prints. Both of these methods are better suited to recycled polypropylene than thermography due to their lower heat requirements and ability to produce high-quality prints without damaging the material.
