Gruber offers a variety of tapes and protective film products to support engineered composite manufacturers:



Masking Tape

Masking tape is used constantly by cast polymer manufacturers to protect mold areas such as back splash door hinges, mold edges, and polydomes during gelcoating and casting. Masking Tape is available by the case in widths of ¾”, 1", 1½”, and 2”.

See detailed information on all tapes here.

  • #515 Utility Grade Masking Tape (Intertape)
  • #519 General-Purpose Masking Tape
  • #591 Double Coated Paper Tape
  • PG505 Crepe Paper Masking Tape
  • RG15 General Purpose Strapping Tape

Protective Film

Gruber Protective Films are perfect for protecting the finished surface of all of your cast polymer products. Different protective film products are required for cultured marble compared to solid surface, and Gruber has them both.  Designed to protect the finish of any product during shipping, storage, or installation, protective film is the best way to insure your product looks as good as the day it was made.

Note: Certain items in the list may have longer lead times and/or additional freight charges attached. Call for availability or more information.


Clear Protective Film - For Cultured Marble and General Purpose Applications

This film is specifically developed for Cultured Marble applications, with lower tack, and less residue than blue protective film.


Co-Extruded Clear Protective Film

The coextruded is a little thicker than the 2 mil regular film, and it should perform equally well on both cultured marble and solid surface applications.
Note: All co-extruded protective film is drop-shipped, and conditions apply.


For Solid Surface Applications - Blue Protective Film

Specifically designed for solid surface applications. Higher tack, with more residue than clear protective film.


* Blue Protective film and co-extruded protective film are available F.O.B. Rockledge, FL only.
** Special order item - minimum order based on size requested applies. Lead times apply.
