Quality is a process, not a badge.
Diller Kids connects material selection, product development, production control and market-specific documentation so buyers can evaluate each project with clarity.
Define the requirement before production begins.
Material, construction, testing and documentation depend on the selected model, destination market, age group and order requirements. We confirm these details project by project instead of treating every bottle as identical.
Materials selected for product function and market needs.
Diller Kids products may use the following food-contact material families. Final construction and documentation are confirmed against the specific model.
304 stainless steel
A widely used stainless steel direction for durable bottle bodies and insulated structures.
316 stainless steel
Used in selected product directions where the design brief calls for a higher-grade inner liner.
Tritan and PPSU
Transparent or translucent material options used for selected lightweight and child-focused formats.
PP and silicone
Common component materials for lids, straws, seals, handles and other functional parts.
Material statements, test scope and reports should always be matched to the exact product, colour, component construction and target market.
Checks continue from incoming material to packed order.
The control plan is adjusted to the product and cooperation requirements.
