What this packaging is

Thick-wall construction and a compact 4ml footprint make this USA-made polypropylene jar a go-to for sample packaging, lip products, pharmaceuticals, and nutraceuticals that demand precise small-volume containment. The 0.1oz / 4ml 33-400 PP Jar from MRP Solutions features a straight-sided profile with a 33-400 neck finish, giving it broad compatibility with standard closures right out of the gate. Available in white, natural, and clear PP, with offset print decoration supported for branded or compliance labeling. Domestic manufacturing keeps lead times tight and supply chains simple. PCR content can be incorporated for brands with material reduction commitments. At 4ml, it's purpose-built for trial formats and specialty formulas that need serious protection in a small package.

Why brands choose this
