Shandong PsiPrime Packaging Co., Ltd. specializes in the research, development, and manufacturing of eco-friendly food-grade packaging products. Our product portfolio includes compostable food containers, paper-based food packaging, eco-friendly paper bags, food wrapping paper, and disposable catering supplies. These solutions are designed to meet the diverse needs of restaurants, food delivery platforms, food processors, and retail businesses.
Our focus centers on offering one-stop customization services ranging from custom sizes, structural engineering, material weight selection to custom multi-color printing.
We emphasize stable delivery performance and strict quality control, ensuring efficient and reliable global supply chain management for brands worldwide.
For industries demanding extreme moisture resistance, high compression tolerance, and physical durability, waxed cardboard sheets are an irreplaceable industrial staple. At Shandong PsiPrime Packaging Co., Ltd., we combine advanced paper chemistry with high-capacity waxing technologies to produce industry-standard-setting materials.
Wet Waxing: Applies a layer of wax to both sides of the sheet, creating a glossy, high-barrier finish that is ideal for direct moisture contact (e.g., seafood, wet ice, and fresh produce).
Dry Waxing: Submerges the paper fibers in molten wax without leaving a heavy film on the surface. This creates an oil-resistant surface that remains easy to handle and glue.
Our OEM capabilities allow clients to specify material configurations:
Our waxed liners undergo rigorous testing to ensure peak mechanical performance:
As a premier manufacturing hub, Shandong provides significant industrial advantages that allow PsiPrime Packaging to offer market-leading values in custom waxed cardboard sheets production.
Shandong houses some of the world's largest paper mills. By sourcing premium virgin wood pulp and recycled liners locally, we reduce logistics markups and guarantee pricing stability for long-term supply agreements.
Our factory utilizes advanced computerized high-speed waxing and laminating lines. This ensures a uniform coating thickness across every sheet, preventing raw spots that compromise moisture resistance during shipping.
Located near Qingdao Port, one of the world's busiest container hubs, we minimize inland transportation costs. This proximity enables us to secure reliable shipping windows to North America, Europe, Australia, and Southeast Asia.
Our facility features clean-room production standards, advanced machinery, and rigorous quality check protocols to ensure food-grade compliance and structural integrity.
Waxed cardboard sheets serve as critical components in industrial packaging systems. We engineer specific grades tailored to these primary global market applications:
During hydro-cooling and field-packing, standard cardboard boxes disintegrate. Our wax-impregnated sheets maintain their compression strength, providing structured support for melons, grapes, broccoli, and root vegetables.
Transporting frozen or iced poultry requires direct contact barriers. PsiPrime’s food-grade waxed sheets prevent grease, oil, and purge liquids from leaking through, keeping secondary shipping cartons clean and stable.
Machined parts coated in anti-rust oils require greaseproof interleaving sheets to prevent staining. Additionally, heavy-gauge dry-waxed sheets serve as temporary protective barriers on construction floors.
As a forward-looking enterprise, Shandong PsiPrime Packaging Co., Ltd. is actively preparing for future regulatory landscapes. Historically, paraffin-waxed cardboard faced recycling challenges because standard repulping mills could not separate the petroleum-based wax from the wood fibers.
To solve this problem, we are investing heavily in biodegradable wax formulations. By blending natural plant-based waxes, soy-based coatings, and bio-polymers (such as PLA and PHA), we are developing a new generation of waxed sheets that deliver traditional moisture resistance while remaining fully compostable and recyclable.
These advancements help our international partners comply with strict packaging waste directives, such as the EU Packaging and Packaging Waste Regulation (PPWR), without sacrificing performance.
