Explore our core biodegradable, compostable, and plastic-alternative product line engineered to meet stringent international standards.
The global commercial and industrial packaging sector is undergoing a profound paradigm shift. Driven by aggressive environmental legislation—such as the European Union’s Single-Use Plastics Directive (SUPD), stringent plastic bans in China, and regional EPS (Expanded Polystyrene) prohibitions across North America—brands are seeking viable alternative barrier materials. Among these, waxed paper packaging has emerged as a front-runner, bridging the gap between functional grease-and-moisture resistance and biological circularity.
Historically valued for dry food packaging, wax coating technology has evolved significantly. Traditionally reliant on petroleum-based paraffin, the modern packaging industry now operates in a highly technical space involving vegetable-based waxes (soy, palm, and candelilla), beeswax, and innovative water-based bio-polymers (aqueous coatings). This chemical transition has allowed waxed paper bags, sheets, and wraps to retain high physical performance while aligning with global compostability and recyclability frameworks.
Compound annual growth rate (CAGR) of over 6.8% for sustainable bio-barrier flexible papers through 2030.
Over 80 countries have enacted strict regulatory caps on single-use poly-coated food service items.
Demonstrable life-cycle safety parameters backed by FDA, LFGB, and EN 13432 compostability certifications.
From a commercial perspective, Chinese exporters are leading the global distribution of these products. Leveraging sophisticated raw-material integration, scaled manufacturing units, and advanced flexographic printing lines, Chinese factories provide the global market with cost-competitive, premium greaseproof and wax-coated products. The structural reliability of Chinese exports guarantees supply chain stability for large-scale enterprise partners across Europe, America, and Southeast Asia.
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.

Inside our high-precision production facility. We maintain fully integrated processes from raw substrate cutting to automated final product packing under sanitary conditions.
For a waxed paper bag to perform reliably in demanding commercial environments, the underlying materials must resist grease penetration, moisture vapor transfer, and physical tearing. The traditional method uses microcrystalline paraffin waxes. Paraffin forms a continuous hydrophobic film over cellulose fibers, yielding exceptional barrier properties. However, paraffin remains persistent in ecosystems and is difficult to process in standard municipal recycling pulpers.
To address these challenges, Shandong PsiPrime Packaging has engineered advanced biodegradable formulations. Our technical roadmap focuses on three main alternative coating technologies:
Water-borne polymer dispersions are applied directly to raw kraft or glassine substrates. Once cured, they form a micro-thin, grease-resistant layer that repels hot oils and liquids. Crucially, during the recycling re-pulping process, these aqueous coatings dissolve back into the water phase, allowing 100% fiber recovery without clogging processing equipment.
Blending plant-based waxes, such as soy and carnauba, with purified beeswax yields a robust, non-toxic coating with a high melting point. This organic matrix provides excellent moisture barrier protection, ideal for wrapping warm bakery goods, fresh cheeses, and premium meats without affecting taste profiles.
For heavy-duty applications requiring high heat resistance and moisture seals (such as microwavable bowls and hot liquid packaging), we utilize bio-plastics like Polylactic Acid (PLA) and Polybutylene Succinate (PBS). These biodegradable coatings offer strong mechanical strength and compost rapidly in industrial composting systems.
| Coating Type | Grease Resistance (KIT Test) | Moisture Vapor Transmission Rate (MVTR) | Primary Industrial Application | End-of-Life Profile |
|---|---|---|---|---|
| Standard Paraffin Wax | Kit 9 - 11 | Low (< 20 g/m²/day) | Cold food storage, meat wraps | Non-compostable, landfill-bound |
| Aqueous Coating | Kit 7 - 10 | Medium (~ 45 g/m²/day) | QSR sandwich wrapping, burger boxes | 100% Recyclable, repulpable |
| Vegetable Wax Blend | Kit 6 - 8 | Low-Medium (~ 35 g/m²/day) | Artisan bakery, dry confectionery | Home and industrial compostable |
| PLA Bio-lining | Kit 12+ | Extremely Low (< 15 g/m²/day) | Hot coffee cups, microwavable bowls | Industrial compostable (EN 13432) |
Flexible waxed paper and packaging materials are utilized across diverse localized commercial landscapes, each requiring specialized material designs:
Artisan Bakeries & Organic Food Markets
In highly eco-conscious markets, companies use custom-printed glassine and vegetable-waxed bags to package bread, pastries, and deli meats. The demand focuses on home-compostable and unbleached kraft papers that align with regional zero-waste regulations.
Quick-Service Restaurants & Food Delivery Platforms
Fast-food chains use large greaseproof wrapping rolls and double-wall insulated cups. The emphasis is on structural reliability under heat and moisture, preventing grease from leaking through packages during transit.
Fruit Growing & Protection Envelopes
Orchards in tropical and subtropical regions use specialized waxed protection bags (e.g., for mangoes and guavas). These agricultural bags shield growing fruit from insects and heavy rains while maintaining high tear strength in humid weather.
Shandong PsiPrime Packaging supports these diverse regional requirements with customizable raw-material selections, variable thickness specifications (from lightweight 28gsm to heavy-duty 90gsm sheets), and food-safe inks for custom branding.
Addressing key questions about technical specifications, environmental compliance, and global shipping logistics.
Complete packaging configurations designed for hot liquids, retail packaging, and greasy foods.
We continue to research and develop biodegradable and compostable products. Partnering with global enterprises, we help build low-carbon supply chains for food service and commercial packaging.
