Utien Pack Contributes to Meat Packaging Blue Book

Utien Pack Advances Meat Packaging Technology

Meat packaging is no longer a simple final step before distribution. It has become a critical part of food safety, shelf-life extension, product presentation, logistics efficiency, and brand value. As the meat industry moves toward higher standards, better cold-chain distribution, and more diversified product formats, packaging technology must also evolve from basic protection to a complete system of preservation, automation, hygiene, and quality control.

This industry direction is clearly reflected in the BLUE BOOK ON APPLIED TECHNOLOGIES FOR MEAT PACKAGING, a professional reference developed with the participation of industry associations, research institutions, packaging material companies, and packaging equipment manufacturers. The Blue Book highlights that meat packaging now plays a key role in maintaining product quality, extending shelf life, reducing loss, and supporting the high-quality development of the meat industry. It also points out that technologies such as vacuum packaging, modified atmosphere packaging, vacuum skin packaging, active packaging, intelligent packaging, and new equipment solutions are becoming increasingly important for the sector.

Vacuum Skin Packaging and Unifresh® Technology

The BLUE BOOK ON APPLIED TECHNOLOGIES FOR MEAT PACKAGING gives significant attention to vacuum skin packaging as one of the important technologies for modern meat packaging. Compared with ordinary vacuum packaging, vacuum skin packaging uses a specially designed top film that closely fits the surface of the product and seals with the tray or bottom material. This creates a package with reduced free air, clearer product presentation, stronger protection during storage and transportation, and improved retail display.

The Blue Book explains that vacuum skin packaging is especially suitable for high value meat and seafood products, including premium steaks, lamb chops, shelf life sensitive seafood, cold chain meat, fresh e-commerce products, and high value ready to eat chilled products. These applications show that skin packaging is not only a preservation method, but also a solution for product presentation, juice control, transportation protection, and consumer experience.

Utien Pack’s contribution to this field comes from long term equipment development and industrial application. As one of the editing companies of the Blue Book, Utien Pack brings practical experience from real production lines into the industry discussion. In 2013, Utien Pack achieved a breakthrough in online vacuum skin packaging technology, supporting the development of continuous and automated skin packaging applications for different product categories.

On this foundation, Utien Pack developed its own Unifresh® technology, a skin packaging solution designed for products with higher protrusion, irregular shapes, or premium display requirements. This contribution directly reflects one of the key messages of the Blue Book: successful meat packaging depends on the coordination of packaging materials, product characteristics, equipment structure, heating control, vacuum control, sealing performance, and process stability. For meat processors, this means that vacuum skin packaging should not be treated as a single machine function, but as a complete technical system.

Thermoforming Packaging: A Key Technology Covered by the Blue Book

The Blue Book also covers thermoforming packaging as an important packaging technology for meat and meat products. Thermoforming systems are widely used in standardized and continuous production because they can form the bottom film online, load products, complete vacuuming or gas flushing, seal the package, and cut it into final packs. Depending on the product and shelf life target, thermoforming packaging can support vacuum packaging, modified atmosphere packaging, shrink packaging, zipper packaging, and vacuum skin packaging.

This is important because meat products vary greatly in shape, moisture content, fat level, storage condition, and sales channel. A sliced sausage pack, a fresh steak, a seafood product, and a cooked meat product may require completely different film structures, forming depths, sealing methods, cutting designs, and preservation technologies. The Blue Book’s discussion of stretch film packaging, material thickness, forming quality, leakage prevention, hygiene control, and common defect troubleshooting shows that thermoforming packaging is a system-level technology rather than a simple forming-and-sealing process.

Utien Pack’s contribution is to connect this technical knowledge with real equipment design and project experience. Its rollstock thermoforming equipemt, RC Series, supports vacuum, shrink, zipper, modified atmosphere, and skin packaging options for continuous and automated production. This aligns with the Blue Book’s practical purpose: helping meat processors understand how to choose and apply suitable packaging technologies in real production environments.

Rather than focusing only on machine speed, Utien Pack’s thermoforming projects emphasize the matching of product features, film materials, forming depth, sealing conditions, hygiene design, automation level, and downstream connection. This practical experience helps transform the Blue Book’s technical guidance into packaging lines that can operate consistently in daily production.

Tray Sealing and Complete Line Solutions: Connecting Packaging Technology with Factory Operation

In addition to thermoforming packaging, the Blue Book covers preformed tray packaging and tray sealing as important solutions for fresh meat, poultry, seafood, ready meals, and chilled products. Tray sealing can be applied for top sealing, modified atmosphere packaging, and vacuum skin packaging, depending on product requirements. This makes it one of the most flexible packaging formats for modern meat processing and retail food production.

The Blue Book also highlights that meat packaging is closely connected with product quality, shelf life, hygiene, safety, production efficiency, and final presentation. In real factories, these results are not achieved by the sealing machine alone. They depend on the coordination of tray handling, product loading, weighing, filling, gas flushing, sealing, printing, labeling, inspection, and conveying. This is why packaging equipment is increasingly moving toward automation, integration, and intelligent production.

Utien Pack’s contribution in this area is its experience in automatic preformed tray packaging systems and complete line solutions. The Blue Book introduces Utien Pack’s preformed tray packaging series as supporting top sealing, modified atmosphere packaging, and skin packaging, and notes that complete line solutions can cover feeding, weighing, filling, packaging, printing, labeling, inspection, and conveying.

This is where Utien Pack’s role as a editing company becomes meaningful. The company does not only provide equipment examples; it contributes production side experience to the broader industry discussion. For meat processors, the value of tray sealing technology is not only in producing an attractive package, but also in building a stable workflow that supports hygiene, capacity, consistency, and long-term operation.

Utien Pack’s role is to translate these needs into practical machine design and production ready solutions.

Advancing the Future of Meat Packaging

The future of meat packaging will be shaped by safety, efficiency, sustainability, and intelligent production. The Blue Book calls for further development in standardization, multifunctional packaging, green materials, intelligent sensing, RFID technology, and data driven packaging management.

Utien Pack will continue to support this development through equipment innovation, national standard participation, and real project experience. From thermoforming packaging to tray sealing, from vacuum to modified atmosphere and skin packaging, and from single machines to fully integrated packaging lines, Utien Pack remains committed to one clear goal: helping food manufacturers build safer, more stable, and more competitive packaging systems.
