What Is Leak-Proof Paper?

Leak-proof paper is a specially coated or laminated paper designed to contain grease, water, sauces, or food oils within the packaging. Unlike regular food wrapping paper, which may absorb and eventually break down with moisture, leak-proof paper is made to repel and contain.
Our solution combines high-density base paper with food-safe PE, PLA, or advanced grease-resistant coatings, resulting in a high-performing material ideal for hot, wet, or oily foods. It is widely used across quick-service restaurants (QSRs), bakeries, fast food chains, meal prep services, and frozen food packaging.

Leak-proof paper is highly versatile and essential for both on-the-go food service and industrial food packaging. Popular applications include:

Line trays in fast food chains, cafeterias, or food trucks - easy cleanup and grease containment.

3. Fried Chicken and Seafood Packaging

Absorbs excess oils but prevents leakage through the packaging. Perfect for crispy, juicy products.

4. Steamed and Moist Foods

Wrap bao buns, tamales, or rice balls with full moisture barrier without sticking.
