How to Choose a Stamp for Plastic
Plastic, poly mailers, and coated packaging need a specific ink formulation — standard ink smudges or fails to set on non-porous surfaces, so this collection uses our permanent (glossy) pre-inked stamps, made specifically to stay set on plastic and similarly smooth materials. These come ready-inked, with no separate ink pad needed, and are available across several sizes up to our largest, 8cm × 5cm, which comfortably fits a full logo with business name and social handle. That larger size is a maximum print area rather than a fixed shape, so your design is fitted proportionally to whatever shape it is. If you're also stamping paper packaging alongside plastic, note that this is a different ink formulation from our matte range — you'll likely want both if your packaging mixes materials.
