Compare
Styrofoam is still everywhere for one strong reason: it is cheap. But price is not the only criterion — microwave safety, brand image and regional regulation increasingly favour paper packaging.
This comparison is honest about where styrofoam wins, and clear about the risks for a growing business.
| Criteria | Paper Lunch Box | Styrofoam |
|---|---|---|
| Unit cost | Generally higher than styrofoam | The cheapest in its class — the main reason it persists |
| Heat insulation | Sufficient for normal delivery runs | Superior — foam holds heat longer |
| Microwave | SEALPAK lunch boxes are microwave safe up to 100°C for 1 minute | Must not go in the microwave |
| Saucy / oily dishes | PE leakproof lining holds broth and oil | Prone to leaking at seams and punctures easily |
| Brand image | Clean, modern, eco-conscious | Associated with a budget feel |
| Branding | Custom printable with your logo | Practically unprintable — plain white |
| Environment | Paper-based and recyclable | Slow to degrade and rarely recycled |
| Regional regulation | Safe from restrictions | Several Indonesian regions have restricted or banned styrofoam for food |
The unit-price gap is real — but for a brand-building business, a plain white unbranded box is a lost promotion at every single order. SEALPAK plain paper lunch boxes sell with no minimum order (packs of 50 pcs), so you can measure customer response before committing.
