Ribbed 48-400 Straight Sided Threaded Closure

What this packaging is

Wide 48mm geometry and a 400-thread neck finish make this closure a workhorse across beauty, wellness, and supplement packaging. The Ribbed 48-400 Straight Sided Threaded Closure is a polypropylene cap with a vertically ribbed exterior for confident, no-slip handling at scale. Its straight-sided, low-profile form — just 0.45 inches tall — stacks efficiently and integrates cleanly into automated filling lines. Made in the USA, this closure keeps domestic lead times short for brands scaling production fast. It fits containers used for vitamins, capsules, gummies, and powders, and can be specified with PCR content for brands with sustainability commitments.
