Takeout Packaging Upgrade: Food Packaging with Oil- and Water-Resistant Packaging Paper Bags

The rapid growth of the takeout industry has made the oil- and water-resistant properties of packaging a key factor in consumer experience. While traditional plastic food containers can address leakage issues, they face environmental policy restrictions and recycling challenges. Today, packaging paper bags have achieved breakthroughs in oil-resistant and waterproof performance through technological innovation, making them the core choice for Food Packaging upgrades. Guangdong Guowei Guanli New Materials Co., Ltd., with 17 years of experience in replacing plastic with paper, offers customized sustainable Packaging Solutions for takeout scenarios. These solutions not only meet practical needs but also help brands fulfill their environmental commitments.

 

Technological Breakthrough: Dual Assurance from Materials to Processes

The oil-resistant and waterproof performance of packaging paper bags stems from innovative material combinations and processing techniques. Guowei Guanli employs a “kraft paper + plant-based lamination” composite structure, with the inner lamination layer made from cornstarch to form a nanoscale protective film. Oil penetration rates are controlled below 0.2g/24h, far exceeding the industry standard of 1g/24h. After adopting this solution, a certain spicy hot pot brand saw a 80% reduction in complaints about soup leakage and a 35% increase in packaging reputation.

For high-temperature takeout scenarios, a heat-resistant oil-proof process has been developed, enabling packaging paper bags to withstand direct contact with hot food at 120°C without releasing harmful substances. A fried chicken brand's tests showed that using these paper bags reduced oil absorption by 50% and extended the crispiness of the food by 1 hour. Additionally, laser micro-perforation technology balances breathability and waterproofing to prevent food from spoiling due to sealed heat. A sushi brand that adopted this technology extended the freshness of its products by 2 hours.

Scene adaptation: comprehensive coverage across all categories, balancing environmental friendliness and practicality

Different takeout categories have varying packaging requirements. Packaging paper bags achieve full-scenario adaptability through customized design. For soup-based foods, packaging paper bags are used with leak-proof folded edges, capable of holding 400ml of liquid upside down for 10 minutes without leakage. For dry foods like fries, windowed custom paper bags are used, which both showcase the product and maintain crispness through ventilation holes. After a fast-food chain replaced all its packaging categories, plastic usage decreased by 65%, and annual environmental protection costs were reduced by 400,000 yuan.

 

Brown paper bags, after waterproof treatment, become the ideal takeout packaging for beverages like bubble tea. A tea beverage brand replaced dual packaging with cup sleeves and plastic bags, reducing per-customer packaging costs by 0.3 yuan. Due to its biodegradable properties, it obtained “green takeout” certification, and platform traffic diversion led to a 15% increase in orders. This “multi-use” characteristic positions packaging paper bags at the core of takeout packaging upgrades.
