Smooth 28-400 PP Push Pull Cap for Dish Soap

What this packaging is

A 3.5mm orifice and push-pull dispensing mechanism make this 28-400 PP Push Pull Cap a practical, no-fuss closure for dish soap and similar household liquid products. Built from durable polypropylene with a ribbed collar for confident grip, it fits any container with a standard 28mm 400-finish neck — one of the most common neck finishes in the market, which means broad compatibility across your bottle lineup. The glossy finish keeps shelf presence clean, and PCR content is available for brands with sustainability commitments. At 4 grams, it's light without feeling cheap — a reliable everyday closure that holds up through repeated use.

Why brands choose this

• Precision dispensing built for liquid formulas: The 3.5mm orifice paired with a push-pull mechanism gives consumers direct control over flow — reducing waste and mess at point of use, which matters in a household category where over-dispensing is a known frustration.
• Standard 400 neck finish means maximum bottle flexibility: The 28-400 spec is one of the most widely used neck finishes across HDPE and PET bottles, so this cap integrates easily into existing packaging lines or gives product developers broad options when sourcing containers.
• PCR content available for brands with material goals: This cap can be produced with recycled polypropylene content, giving brands a credible sustainability story without switching formats — a straightforward way to reduce virgin plastic use in a high-volume household product.
