Hygienic, Grease-Resistant Food Paper Bags for Restaurants & Food Brands
As China’s first listed paper packaging supplier, Nanwang Pack engineers high-performance, direct-food-contact paper bags built for quick-service restaurants (QSR), bakeries, cafes, delis, and food delivery platforms. Produced in dedicated dust-free workshops certified under BRCGS (Grade A+) and ISO 22000:2018, our food packaging bags combine superior tensile strength, leak-proof grease resistance, and eco-friendly recyclability.
Core Food-Grade Paper Bag Styles & Structural Designs
We manufacture a full spectrum of food bag structures tailored to hot, cold, greasy, or freshly baked food items:
-
SOS Bags (Self-Opening Sacks): Heavy-duty flat-bottom takeaway bags that stand upright on packing counters for rapid order assembly. Available with or without flat handles for burger chains, meal boxes, and grocery delivery.
-
Pinch Bottom Bags: Slim, envelope-style bags with a folded and heat-sealed/glued bottom flap that prevents grease or crumbs from seeping through seams—ideal for pastries, fried snacks, and hot sandwiches.
-
Greaseproof Bakery & Deli Bags: Lightweight, high-barrier paper pouches engineered to hold oily croissants, donuts, fried chicken, and grilled wraps without oil staining.
-
Clear-Window Bread & Pastry Bags: Combines breathable kraft paper with food-grade PLA or PP transparent display windows to showcase artisanal breads and baked goods on retail shelves.

Frequently Asked Questions About Food-Grade Paper Bags
Q1: Are your greaseproof food bags free from PFAS and harmful chemicals?
A: Yes. Nanwang Pack offers 100% PFAS-free grease-resistant paper bags engineered with food-safe, water-based barrier coatings and high-density natural fibers. They comply strictly with FDA, EU, and BRCGS (Grade A+) food safety standards and are fully recyclable.
Q2: What is the difference between SOS takeaway bags and pinch-bottom bags?
A: SOS (Self-Opening Sack) bags feature a wide, gusseted rectangular bottom that stands upright on its own, making them ideal for packing bulky takeout containers, soup bowls, and multiple meal boxes. Pinch-bottom bags are flat, gusseted pouches with a folded and sealed bottom—engineered specifically to hold direct-contact oily or handheld foods like pastries, burgers, and fried snacks without leaking grease.
Q3: Can your food paper bags handle hot, steamy takeaway foods without tearing?
A: Yes. For hot and humid delivery items, we utilize wet-strength virgin kraft paper paired with moisture-barrier coatings and high-temperature food-grade adhesives, ensuring the bag maintains its structural rigidity and handle strength throughout transit.
Q4: What is your Minimum Order Quantity (MOQ) and can we request food-testing samples?
A: Because our high-speed food-bag lines operate at an annual capacity of 9.5 billion+ food packages, our standard MOQ for custom-printed food bags starts from 20,000 to 50,000 pieces per size depending on bag dimensions and GSM. We provide free stock samples for your kitchen grease and heat testing (you only cover express shipping).
