About Masking

Many plastics, especially those used for displays or signs, are enshrouded in some kind of protective covering, called masking. The two most common are paper masking and poly masking (polyethylene film). LEAVE THE MASKING ON WHILE YOU CUT! If you need to draw your shape on the material first and then trace it with a tool then paper masking should be requested and there will be a bit of premium paid since paper costs more than poly film. As a general rule, poly will be shipped unless otherwise specified.

Remember to peel back the masking

The sheet masking should be left in place during most fabrication operations to protect the sheet surface. The masking may be removed for intricate detail work on the sheet if necessary. Certain heat sources used in line bending and thermoforming operations may also require removal of the masking.

Unmasked sheet should be stored in the original shipping cartons. Avoid handling unmasked sheet unnecessarily.

You can remove the paper masking with a cardboard tube by rolling the masking around it. If the adhesive has hardened, moistening it with aliphatic naphtha, hexane or kerosene will help to soften it. Do not use gasoline or sharp-edged objects such as razor blades. Any oily film left behind by solvents should be removed immediately by washing.

Banner Stands And A Shout Out To SCL Imaging!

Owen and his crew over at SCL Imaging did a great job on our TIVAR bulk handling/linings banner stand we needed for an upcoming trade booth. The process is pretty simple – lay it out, flip it to a PDF, and email it to them. Turn around was quick, no hassles, and the quality is A#1!

SCL Imaging is a full digital print house capable of doing print on demand, posters, point of purchase displays, food service displays, exhibits and displays, lambda imaging, flatbed imaging and a lot more.

Give’m a call with your next project and let’m know the PlasticGuy sent you

Thanks again, Owen
