Smooth Finish for Labels & Customization
Unlike ribbed or heavily textured closures, Goodlook® lids feature a smooth matte surface across the top and sides. This creates a clean presentation and provides usable surface area for branding and package identification.
The smooth finish works well with:
- Top-applied lid labels
- Sidewall labels
- Tamper-evident label configurations
- Applicable custom-decoration methods
Compatible custom concentrate labels are available for building a coordinated jar-and-lid packaging system.
Push-Down-and-Turn Child-Resistant Closures
Both sizes use a push-down-and-turn child-resistant closure design commonly used for concentrate packaging.
Child-resistant requirements can vary by product, complete package configuration, and jurisdiction. Brands should verify that the finished jar-and-closure system meets the requirements applicable to their specific product and market.
Foil-Faced, Foam-Backed Liner Included
Each closure includes a foil-faced, foam-backed liner. The smooth foil face provides the product-contact surface, while the foam backing adds compressibility to help the liner conform against the jar opening when the closure is applied.
The current liner measures approximately 0.72mm total thickness. Exact foam polymer, commercial liner designation, and induction compatibility have not yet been verified, so brands should evaluate the complete jar, liner, closure, and product combination under their intended production and storage conditions.

Build a Complete Concentrate Jar System
The 28-400 and 38-400 lids are designed to work as part of the broader Goodlook® packaging system. Makerbaus offers wholesale glass concentrate jars, compatible closures, custom labels, and custom concentrate boxes.
A defined neck finish makes it easier to select compatible components and build a coordinated packaging system around either the compact Goodlook® Mini or the larger Goodlook® Classic.
