PET bottles vs doypacks for supplements

When deciding between PET bottles and doypacks for supplement packaging, brand owners must evaluate product form, shelf presence, and supply chain efficiency. PET bottles offer rigidity and stackability, ideal for capsules and tablets, while doypacks provide lightweight flexibility and reduced shipping costs, often used for powders and gummies. This guide outlines the key differences to help you choose the right format for your private-label supplement line, working with a partner that supports both options under the Personalization model.

What to know first

Before selecting a packaging format, confirm that your supplement form—capsules, tablets, powders, or gummies—is compatible with the container. PET bottles are moisture-resistant and suitable for solid doses, while doypacks require a resealable zipper and are better for powders or soft chews. Also consider your target market's preferences: bottles convey pharmaceutical-grade quality, whereas doypacks appeal to eco-conscious consumers seeking reduced plastic use.

Key considerations

Cost, shelf life, and logistics differ significantly. PET bottles have higher per-unit cost and shipping weight but offer longer shelf life due to superior barrier properties. Doypacks are lighter, lowering freight costs, but may have shorter shelf life if not properly laminated. Brand owners should also evaluate filling efficiency: bottles are faster for high-volume lines, while doypacks require specialized equipment for powder fills.

Personalisation and packaging

Under the Personalization model, both PET bottles and doypacks can be customised with your brand's label, color, and closure options. For bottles, choose from various neck finishes and cap styles; for doypacks, select size, zipper type, and gusset dimensions. Artwork and copy are your responsibility, ensuring compliance with your target market's regulations. DAT Supply provides technical specifications to guide your design choices.

Documentation scope

You will need to provide product specifications, ingredient lists, and any third-party test reports for raw materials. For packaging, supply artwork files in the required format and dimensions. DAT Supply may request a certificate of analysis for the supplement formulation to verify compatibility with the chosen container. All final claims and label compliance remain your responsibility as the brand owner.
