About TDI Custom Packaging

Manufacturer of Custom Poly Bags & Film



About TDI

TDI Custom Packaging is a plastic blown-film extruder that specializes in the manufacture of made-to-order plastic bags, film, and tubing.

TDI has been producing US-made quality packaging products since 1974.

TDI has a simple premise —

High Quality,

Lower Minimum Orders

Custom Packaging

with shorter lead times than most.




TDI extrudes, converts, and prints a wide range of plastic bags, sleeves, tubing, and other high- and low-density polyethylene products.

We’ll work with you on projects of almost any size, and if we can’t help you, we’ll recommend someone who can. We specialize in smaller quantity production runs, and can often complete jobs faster.

— we have shorter lead times than most!

“From the office to the plant, everyone goes above and beyond to take care of the customer. I never worry when I place an order with TDI, that’s not very common. I can’t say enough good stuff.”

— Kevin Lynch

Environmentally Conscious

TDI only uses premium FDA-approved resins to manufacture our products. We are environmentally conscious and maintain strict compliance with the Air Quality Management District (AQMD) and the EPA at all stages of production.
