BUYER RESOURCE CENTER

Make bottle decisions with fewer assumptions.

Practical guidance for supplement brands, contract manufacturers, packaging distributors and sourcing teams.

How do I choose a bottle capacity?

Start with filled volume, capsule or tablet count and headspace. Then confirm dimensions, neck finish and closure through a sample.

Should I choose PET or HDPE?

PET offers clarity and a rigid premium appearance; HDPE is opaque and widely used for robust supplement packs. Compatibility must be confirmed with the actual formulation.

What makes a bottle child-resistant?

Child resistance depends on the complete bottle-and-cap system and applicable testing—not cap appearance alone. Request evidence for the exact combination and market.

Which finishes are available?

Available directions include electroplating, spray coating, sandblasting, silkscreen, hot stamping and labels.

What is the usual lead time?

The existing corporate FAQ states that standard items are typically 15–25 days after order confirmation and deposit. Custom tooling or complex decoration requires a project-specific schedule.

What should I include in an inquiry?

Share contents, target capacity, quantity, destination, material preference, bottle color, cap, liner, decoration and required compliance.

Which certificates are available?

The corporate materials display ISO 9001 and other company certificates. Request current copies and verify their validity, scope and applicability to the exact product.
