Explore our foundational food-grade packaging lineup, engineered for high-heat performance, ultimate oil resistance, and environmental compliance.
In the highly competitive global fast-food landscape, food presentation, sensory appeal, and packaging integrity are paramount. Greaseproof burger sheets represent a crucial intersection of material science, food safety, and brand aesthetics. From holding together gourmet brioche cheeseburgers to preventing external oil permeation in high-volume delivery operations, these specialized wrapping sheets are anything but simple paper.
Historically, the food packaging industry relied heavily on plastics and fluorochemical coatings (PFAS) to achieve liquid resistance. However, regulatory shifts globally—ranging from the European Union's Single-Use Plastics Directive (SUPD) to US state-level PFAS bans—have catalyzed a paradigm shift. Modern quick-service restaurant (QSR) networks and food delivery conglomerates require zero-plastic, biodegradable, and high-barrier alternatives that maintain structural integrity when exposed to lipids, steam, and heat. This whitepaper analyzes the manufacturing dynamics of greaseproof burger sheets, exploring how key manufacturing hubs leverage material engineering to meet these multi-layered procurement demands.
The core functionality of greaseproof paper is rated utilizing the TAPPI T 559 standard (commonly referred to as the Kit Test). The Kit Rating measures the paper's resistance to penetration by a series of mixtures containing varying ratios of castor oil, toluene, and heptane. The scale ranges from Kit 1 (lowest grease resistance) to Kit 12 (highest grease resistance).
Achieved through a sulfuric acid wash process that gelatinizes cellulose fibers, fusing them into a non-porous structure. Offers natural grease barrier properties without added chemicals, suitable for high-end baking sheets and wrapping.
Thin layers of food-grade liquid silicone applied to the surface. It provides excellent release (non-stick) properties and oil resistance, ensuring that cheese and moisture do not compromise the wrapping or cling to the food.
Constructed by laminating thin aluminum foil to paper with an air-bubble pocket layer. The honeycomb design traps air to maintain temperature (thermal retention) while delivering 100% grease protection on the foil side.
For high-volume hamburger packaging, a Kit rating of Kit 4 to Kit 7 is typically target-efficient. Achieving this range without the use of synthetic fluorinated polymers requires advanced mechanical refining of pulp fibers. Extremely dense refining increases the fiber-to-fiber hydrogen bonding, making it difficult for grease molecules to find pathways through the web. Shandong PsiPrime Packaging Co., Ltd. uses this precise mechanical configuration to offer high-durability wrapping options that balance performance and eco-responsibility.
Shandong PsiPrime Packaging Co., Ltd. is committed to advancing sustainable packaging solutions and promoting the reduction of single-use plastics, helping foodservice and food-related industries transition toward more environmentally responsible operations.
The company strongly believes that biodegradable and compostable packaging materials represent the future of sustainable development. It actively promotes the concept of “plastic alternatives” and works to raise awareness of eco-friendly packaging across global markets. With extensive industry experience and a reliable supply chain, we provide high-quality, sustainable food packaging solutions to customers in many countries and regions.
The current global imperative demands that manufacturing systems evolve from simple plastic coating (PE lining) to advanced biodegradable barriers. Under the stewardship of Shandong PsiPrime Packaging Co., Ltd., R&D is focused on compostable food containers, paper-based food packaging, eco-friendly paper bags, food wrapping paper, and disposable catering supplies. By optimizing chemical formulations and raw material sourcing, the factory is helping QSR chains achieve their net-zero greenhouse gas emission targets without sacrificing packaging functionality.
In traditional greaseproof manufacturing, synthetic polymers like Polyethylene (PE) coating are applied to paper to provide a barrier against water and fats. However, PE-lined paper is challenging to recycle in standard pulping mills because the plastic layer cannot easily be separated from the paper fibers. To solve this, Shandong PsiPrime Packaging Co., Ltd. focuses on three primary eco-friendly alternatives:
Global procurement teams face complex supply chain dynamics, including rising shipping costs, variable raw material pricing, and strict import regulations. China has emerged as the premier manufacturing hub for greaseproof burger sheets due to structural advantages that cannot easily be replicated in other regions.
In China, greaseproof packaging factories are situated in proximity to major pulp processing centers and petrochemical-free coating chemical suppliers. This cluster-based industrial organization allows for incredibly low lead times. When a global brand requests a custom design—for instance, a 40gsm Kit 6 sheet printed with soy-based inks for a promotional campaign—our factory can source the raw materials, manufacture, inspect, and package the finished product within a fraction of the time required by Western competitors.
Modern Chinese factories leverage heavy capital investments in German and domestic high-speed flexographic printing and slitting machines. These production lines operate with high automation levels, ensuring consistent sheet sizes and minimizing cutting dust. Slitting tolerances are kept within ±0.5mm, which prevents jams in automatic burger wrapping dispensers at restaurant counters. This level of precision is achieved through a systematic production flow spanning multiple specialized units.
Our complete machinery infrastructure and workflow ensure absolute food safety, precise sizing, and high-efficiency output.

Every commercial food sector requires specific physical characteristics from its packaging sheets. We provide tailored solutions to match the unique thermodynamic and chemical requirements of diverse operations:
For deliveries requiring 20 to 45 minutes of transit, standard wrapping paper is insufficient. When steam condenses inside plastic wrappers, it turns buns soggy. Our honeycomb aluminum foil paper provides a dual solution: the foil blocks thermal radiation to keep the burger hot, while the laminated paper absorbs excess steam, preserving the texture of the bread.
For modern dine-in restaurants, the wrapping paper serves as a core branding asset. Using non-toxic, odorless, food-safe soy or water-based inks, Shandong PsiPrime Packaging Co., Ltd. designs customized sheets that prominently display corporate branding. High-definition flexographic printing ensures clean lines and colors that remain stable under heat and oil exposure.
Enterprise buyers looking to import greaseproof burger sheets from China should follow a structured evaluation framework:
Technical answers to support commercial purchasing decisions and ensure regulatory compliance.
Silicone oil coating provides a highly heat-resistant (often up to 230°C/446°F), non-stick, greaseproof barrier. It is ideal for baking and wrapping greasy foods. PE (Polyethylene) coating provides excellent moisture and water resistance but has lower heat tolerance (up to 100°C/212°F) and is more difficult to recycle. Silicone is the preferred option when high heat resistance is required.
Yes. All food-grade wrapping sheets from Shandong PsiPrime Packaging are manufactured using mechanical pulp refining or FDA-compliant silicone/wax coatings, completely avoiding PFAS or fluorine-based grease-resistance chemicals.
We support high-definition, multi-color flexographic printing using eco-friendly water-based or soy inks. Customers can customize logos, patterns, and size dimensions (e.g., standard 12"x12" sheets or custom-sized rolls).
For high-moisture foods, we recommend our parchment paper baking sheets or customized wax food wrapping paper, which feature double-sided barrier coatings to prevent moisture absorption and keep structural integrity.
When stored in dry, cool conditions and protected from direct sunlight, our greaseproof burger sheets maintain their physical properties and grease barrier performance for over 2 years.
