Why CRC Caps?

Child-resistant closures exist to meet a regulatory requirement, but they also need to function reliably under real-world use — the press-down-and-rotate mechanism in HB Packaging’s CRC caps is engineered to pass compliance testing without frustrating adult users.

The C Series covers 24–45mm neck finishes across 7 SKUs, suited for pharmaceuticals, household chemicals, and agricultural liquids that require tamper and child-resistant packaging. For buyers sourcing CRC closures that need to clear compliance without a customs broker sourcing headache, these ship from a factory with 20 years of production history.

CLOSURE SEALING GUIDE

Choose the right liner for child-resistant caps

A good liner choice starts with your formula, bottle neck, filling process and how the product will ship, not the cap alone.

Liner required

Specify the liner with formula and market requirements

Child-resistant caps should be quoted with a liner. Common choices include PE, pulpboard/foil, PE plus foil, or pressure-sensitive liners depending on product compatibility, sealing method and market requirements.

Common order setups

PE Liner

Reliable compression seal for compatible products.

Pulpboard / foil liner

A structured liner option often used when extra barrier support is needed.

PE liner + foil seal

Layered setup for sealing, barrier protection and tamper evidence.

Pressure-sensitive liner

Simple option for dry goods, samples or applications that do not use induction sealing.

Confirm the final setup with your formula, bottle material, neck finish and filling temperature before bulk production.
