At Get Bio Pak Co., Ltd, we have always believed that genuine innovation is born from collaboration. Every success story we create is driven by a shared commitment with our partners to achieve functional excellence, environmental responsibility, and exceptional product quality.
Our recent project with Pınar Süt, one of Turkey’s foremost dairy and beverage producers, is a strong reflection of this philosophy.
This case study showcases how we developed and delivered a customized 6-ounce double-side water-based barrier coated paper cup that perfectly aligned with Pınar Süt’s technical, aesthetic, and brand objectives.
The cup we designed combines performance durability, outstanding print precision, and sustainability — supporting Pınar Süt’s reputation for product innovation and high standards in consumer experience.
Understanding Pınar Süt’s Vision
Pınar Süt, headquartered in İzmir, is a pioneer in Turkey’s dairy and beverage market. As part of their ongoing research and product innovation under Pınar Süt Ar-Ge Merkezi, the company recently introduced several new product lines, including Pınar Protein Pro+, Pınar Latte, Pınar Protein range, Pınar Nature Blend, Pınar Ekşi Krema, and the Pınar Sos family. These products represent a renewed emphasis on health-oriented, high-protein, and naturally blended beverages that appeal to modern consumers.
To match this new generation of functional drinks, Pınar Süt required a new packaging solution that could communicate quality, freshness, and environmental awareness. The challenge was clear: they needed a 6-ounce cup that would not only protect the sensory properties of the drink but also reflect the brand’s visual identity with high-fidelity printing and tactile quality. Additionally, sustainability was a key parameter, as Pınar Süt continuously invests in eco-friendly practices and materials across its production and packaging processes.
Identifying the Technical Challenge
The primary challenge lay in achieving an optimal barrier protection and structural integrity for dairy-based and protein-fortified beverages. Conventional paper cup coatings often rely on polyethylene (PE) films on one or both sides. While PE is effective in moisture protection, it creates challenges in recyclability and end-of-life processing, as the polyethylene layer complicates the paper fiber recovery process.
At the same time, Pınar Süt’s beverage range includes products with sensitive compositions—especially those requiring specific temperature control and resistance to internal moisture and protein residues. This required a barrier solution that was not only functional but also chemically stable, odorless, and compatible with food-contact safety standards.
Introducing Our Double-Side Water-Based Barrier Coating Solution
For this project, our R&D and production teams at Get Bio Pak Co., Ltd. proposed a 6-ounce double-side water-based barrier coated paper cup. Unlike traditional PE-coated cups, our solution employs an aqueous dispersion system, often referred to as a water-based coating, which provides excellent water resistance, grease resistance, and heat sealability—while remaining fully recyclable when processed correctly in paper recovery systems.
Key technical advantages included:
- Dual-side protection: Both the inner and outer surfaces received our proprietary aqueous barrier coating, ensuring strong resistance to moisture and condensation, which is particularly valuable for dairy and protein drinks served both hot and cold.
- Superior print receptivity: The aqueous coating enhances the surface tension of the paperboard, allowing for high-resolution and color-accurate printing. This enabled Pınar Süt to achieve consistent brand colors and sharp logo definition across every production batch.
- Enhanced stiffness and cup integrity: The coating maintains the paperboard’s flexibility while improving its dimensional stability under varying temperatures. The structural feel of the 6-ounce cup conveys quality in hand—a small but essential element of consumer perception.
- Sustainability performance: Water-based barrier coatings minimize the use of plastics, reduce carbon footprint during manufacturing, and maintain compatibility with existing paper recycling infrastructure. The result is a cup that aligns with circular economy goals without compromising performance.
Collaborative Development Process
A defining aspect of this project was our cross-functional collaboration with Pınar Süt’s technical and R&D teams. Both companies share a commitment to product excellence supported by scientific research and data-based decision-making.
Our project began with a series of laboratory evaluations in which Pınar Süt’s R&D team tested various barrier options under realistic product conditions—temperature cycles, fill line performance, and flavor stability. Our role was to provide iterative sample sets with different coating weights and surface treatments until the most effective combination was confirmed.
Concurrently, our printing and prepress teams worked closely with Pınar Süt’s design department to ensure that every cup met the brand’s visual expectations. The vibrant and detailed artwork representing their new product lines demanded precise ink trapping, color matching, and gloss uniformity. Our aqueous coating not only preserved these elements but enhanced them by reducing ink spread, producing brighter and cleaner print tones.
Seamless Coordination with the Sales and Supply Teams
Beyond product design, this collaboration also depended on effective communication and supply coordination. Our sales and client service teams played a critical role in aligning timelines, managing the sample approval process, and translating technical requirements into scalable production steps.
Working alongside Pınar Süt’s procurement and operations staff, we ensured a transition from pilot production to full-scale delivery with complete traceability and production control. The success of this project underscored our company’s ability to combine technical innovation with consistent service quality—a hallmark of long-term partnerships.
Product Deployment and Market Reception
The new Pınar Süt product line was introduced through internal tastings at the company’s R&D center, where employees evaluated the flavor, texture, and presentation of the beverages. For these sampling events, our 6-ounce aqueous-coated paper cups were used exclusively, representing the final packaging adopted for the commercial rollout.
The positive reactions during these internal evaluations validated the combined effort. Team members expressed appreciation for the cup’s smooth print finish, comfortable grip, and the overall premium feel that complemented the beverages. From a manufacturing standpoint, the cups also delivered consistent performance on Pınar Süt’s filling lines, maintaining perfect sealing and minimal waste rates.
Since its introduction, the cup solution has supported the successful launch of the new beverage range, contributing not only to brand visibility but also to a tangible improvement in environmental footprint through plastic reduction at the source.
Outcome and Forward Outlook
This collaboration reaffirmed our engineering and material science capabilities in barrier-coated paper technology. More importantly, it demonstrated how joint development between supplier and brand can create packaging solutions that meet complex product needs while promoting sustainability.
We are grateful for the trust of Pınar Süt’s R&D and sales teams, whose expertise and continuous communication made the process efficient and results-driven. The successful deployment of this solution has reinforced both companies’ positions as innovation leaders within their respective industries.
At Get Bio Pak Co., Ltd, we view this case as more than just a project. It represents our ongoing mission to combine technological precision, environmental integrity, and aesthetic quality in every paper product we design. As the global packaging landscape evolves, we remain committed to advancing aqueous barrier technologies and delivering solutions that serve both business and the planet.
